Emma from my experience with trading standards you must also push them. I had a dispute with a company and trading Standards wrote several letters on my behalf which resolved the matter.
Don't give up keep pushing!
Premature camshaft failure - Vol 3 - **emma**
yes they do seem that they need a little push before they are bothered. wel the lastest is... i hadnt heard from the garage all week, we phoned on monday to get them to fix my car then we would fight after however we didnt hear all week so my dad rang on friday and they said they couldnt get the part, theyv had my car 2 and a bit weeks and known about the problem for about 4 weeks. three hours later they rang me to say i could pick it up and it was sorted, they quoted my dad £378 last week, on the phone he said it would be £408. then we we got to the garage it change to £404. we asked where the extra money had came from and the guy said they had fitted some clip, without telling me. so he took the service charge off and i payed £380. took it home 4:30pm friday by saturday 3:30pm my engine warning light was back on the engine was makeing rattling noises again and shakin violently. toed it back home and rang the garage, cant do anything its the weekend and bank holiday, so how many more weeks without my car??? when we got it home and had a look, total cowboy job, the bolts r loose the cars a mess. you would expect this from a back street garage but a reliable vauxhall dealer.
Premature camshaft failure - Vol 3 - bell boy
get some photos taken for bodgery proof

with the line----you would expect this of backstreet garages i wouldnt agree with this at all---

think on this most "back street garages" are run by profesional men that cut from the thrust of a dealership,the bad ones soon shut once word gets round just like bad main agents just like bad market stalls selling rotten veg

ok :-)

Re:- posts pete and ed - Wed 20 May and ali 1234 Wed 20 May.

Pete and ed.
Upto date postion of the Small Claims action against Vauxhall.
Vauxhall,s defence received on the 21st of May, they deny every thing, but then make another "goodwill gesture" which includes all expenses that I have receipted invoices for, a total of £1,177.42. I am to seek legal advice on the 2nd of June before deciding whether to accept this latest offer or to carry on with the court action, I have until the 8th of June to decide.
We are in contact with ali 1234, and she will be supplying copies of her repair invoice along with her Vauxhall Visual Health Check Report, which also states that Loose Bearing Caps were found.
Is there any one else that has similar written info which they can send to us.

Please send it A.S.A.P.

hi, i have recieved a visual health check report but dont no if it will be any use, i dont really understand what it has on it, it does not state anywhere about the loose bearing caps, i could still send it if you want to have a look? also after having a look since my engine light has came back on, the second cam's bearings are loose now. my dad has also asked if, does anyone know if its a certain engine number that everyones cars are, are they all they same batch?

You will not receive the final Vauxhall Visual Health Check report until the garage has completed all the repairs and you have paid the final bill.
Re: Our post of Wed - 20 May.
Ask your Dad to go back to the Vauxhall garage who is looking at the problem, and ask the mechanic why does he think the Camshaft snapped,and also did he find any Camshaft Bearings loose!! if he did you must get this fact added in writing on his Vauxhall Visual Health check report.
Mon ? 9 April.
You must get the Vauxhall Visual Health Check Report to state that bolts were found to be loose. In my case the report only stated that the Camshaft had snapped, but on talking to the Vauxhall mechanic, when asked why it had snapped, he admitted to me that he had also found 3 Bearing Caps loose, I advised him to add this to his report, which he did.
This is most important to support any claim against Vauxhall UK, as this report is an official Vauxhall document and will be signed by the garage and the customer.

well i have just heard from the garage today and the same thing again, the second cam has snapped! so guess this is going to be another £400 or more. but when we had a look on saturday when my light came on, the three bearing caps were loose, we have mentioned this to the garage. as i had it back less than 24hours since they replace the 1st camshaft.

Once the garage sort this problem since the second camshaft has gone i will ask about the visual health check report and ask them to state about the bearings being loose.

Make sure the comment of "three loose bearing caps" is added to the Visual health check report before you pay the final invoice.
Please advice when the repair has been conpleted, and send me a copy of the report, this will add weight to my court case, this will be the third report to state Loose bearing caps were found.

If the bolts are checked (every service for instance) am I right in thinking camshaft failure shouldn't be a problem?
Premature camshaft failure - Vol 3 - mjm
In over 40 years of driving/servicing and generally working on cars (as an amateur) I have never known correctly installed bolts to work loose. The fact that this is happening on a significant number of these engines tends to suggest that there is an underlying cause responsible for this phenomonen which either Vauxhaull haven't found yet or have found and are keeping quiet. Until this cause is rectified, in my opinion, then it's like playing russian roulette with the engine.

A bolt doesn't have to move far to lose its effectiveness. The question is how long will the cam last with loose bolts?
Premature camshaft failure - Vol 3 - markandchrissie
Surely they were never tightening properly in the factory... You could always loctite them.
Premature camshaft failure - Vol 3 - mjm
So the people who repaired Emma's car have made exactly the same mistake as the manufacturer, even though they knew the bolts were loose and presumably this played a part in the failure?

I don't believe that Vauxhall don't know how to tighten bolts properly. Something is causing them to loosen.
Premature camshaft failure - Vol 3 - markandchrissie
With the proper torque how can a bolt come loose?

Millions of engines rely on the same principle. What "something" do you think might be happening to make them come loose?

It seems that there is a batch of engines built in 2005 that simply weren't torqued correctly on the production line. The new model doesn't seem to be affected - and it's exactly the same engine.
Premature camshaft failure - Vol 3 - mjm
>>If the bolts have become loose in service, then, what's to stop them coming loose again after the mechanic has wafted his torque wrench across them?

This is why I keep coming back to needing to find the root cause of the problem in order to put the correct remedial action in place. What we've heard so far doesn't convince me.<<

Taken from a post by Number Cruncher in volume 2 of this series on Corsa camshafts. N C has forgotten more about engineering than I have known. It is worth perusing the previous volumes on this.

Something is causing the bolts to come loose. It may be some harmonics, vibration or heat cycling of the components. When the cause is known then remedial action can be taken.
Premature camshaft failure - Vol 3 - markandchrissie
Where's the proof they are coming loose ? Virtually all of these cars with broken cams have never been checked from new.

Any "harmonics, vibration or heat cycling of the components" are no different to any other engine - there is nothing "mystic" about this particular engine!

I wouldn't trust a Vauxhall main dealer to change my oil, let alone rebuild a head.

Premature camshaft failure - Vol 3 - **emma**
well we have eventually heard from the garage today, the valves have also bent now, so now how much money will this cost, vauxhall should be to blame. the garage have said they have replaced these from another corsa they had at the garage, so my 3 yr old car has had 2 camshafts fitted and new valves???? and after paying all this money once these bolts come loose again does that mean i have to pay again?? will i have to check these bolts on a regular basis.
Premature camshaft failure - Vol 3 - markandchrissie
Get a written guarantee or change garages.

I've always carried out my own repairs and if in any doubt of a bolt working loose, I use thread lock for peace of mind.

Premature camshaft failure - Vol 3 - brum
I suspect that the bolts are stretching, made of wrong material, i.e. not high tensile. Once the bolt stretches, the tension is released and its free to undo itself. You should retain the loose bolts for further examination/testing. Old bolts should not be reused as the problem will reoccur.

I would have thought that spring washers would have been used on bearing caps, or threadlocking compound (not sure if that would stand the heat though).

It should cost you zero.
there must be some guarantee on the work done.
if the same fault appears within a short time span, the job could not have been done correctly.

if the garage refuse to put your car right, go to trading standards post haste!
Premature camshaft failure - Vol 3 - markandchrissie
8nm wouldn't stretch a bolt - it's little more than finger tight. (Wheels nuts are 110nm). If it was my car I would torgue to 10nm and loctite.

8nm wouldn't stretch a bolt - it's little more than finger tight. (Wheels nuts are
110nm). If it was my car I would torgue to 10nm and loctite.

Staticly no, but there is considerable repetitive peak upward force on the camshaft during operation which is transmitted to the caps. As this area is subject to high pulse loads and high temperature cycling I would think a standard mild steel bolt is not suitable. 8nm also seems ridiculously low tensioning torque - maybe someone could check what torques are used on other vauxhall engines.......
Premature camshaft failure - Vol 3 - pmh2
However do the bolts go straight into threads cut in the aluminium head?


p

Edited by pmh2 on 31/05/2009 at 14:39

Premature camshaft failure - Vol 3 - Number_Cruncher
Yes, pmh identifies the potential weakness in the design.

M6 grade 8.8 bolts should be torqued to about this figure (my calcs say 10Nm, but, I haven't accounted for the possibility of thread stripping in the Aluminium, so, it's about right)

Aside from torque to yield bolts, it's unusual for a bolt to be damaged during installation - wheras a nut is stressed beyond yield every time, and should always be replaced in a high stress or high performance application.

If the joint is correctly assembled, the bolt does not bear all the dynamic load; only about 15% of it. If however the joint and bolt do not share load properly, the bolt takes 100% of the dynamic load.




Premature camshaft failure - Vol 3 - markandchrissie
Looked at the settings on other Vauxhall engines, such as the Ecotec from the 90's and they are the same torque - and have never had any problems that I know of. Why should this engine be any different?
Premature camshaft failure - Vol 3 - Number_Cruncher
>>Why should this engine be any different?

Here's one possibiity:-

If I were involved in investigating this, I would want to check the hardness of the Aluminium alloy cylinder head casting and bearing caps. If there was a batch of poor material, the female threads cut directly into the head would allow the bolt to relax. The same could be true if the bearing caps were soft, allowing a bearing stress failure under the head of the bolt, again leading to relaxation of the bolt.


Premature camshaft failure - Vol 3 - markandchrissie
Personally I think that when the 2nd cam cam loose it was the garage's fault, and they should foot the bill for any further repairs.

It seems virtually all these loose cap incidents occured on cars that had never been checked from new.

Whatever weird and wonderful scientific reasons for their "self-loosening", I maintain that if the bolts were fitted tightly and loctited for peace of mind they would never come undone.
Premature camshaft failure - Vol 3 - Number_Cruncher
>>Whatever weird and wonderful scientific reasons for their "self-loosening

Not weird and wonderful at all - I have come across and dealt with just these mechanisms during my work. It does happen.

>>I maintain that if the bolts were fitted tightly and loctited for peace of mind they would never come undone.

There's much more to bolts than that. There are mechanisms which allow bolts to relax without any rotation which no amount of loctite can cure. In fact, the wrong grades of loctite can prevent a joint working properly, and drastically reduce the fatigue life of the bolt.

For a bit more, have a look at;

www.boltscience.com/
Premature camshaft failure - Vol 3 - markandchrissie
Ok, I'm no expert on the science but have rebuilt many heads without problems like this.

While the reasons you describe may be a potential cause, how many cam caps have actually loosed AFTER being checked/replaced and torqued correctly?
Premature camshaft failure - Vol 3 - Number_Cruncher
>>have actually loosed AFTER being checked/replaced and torqued correctly?

We don't know - perhaps, in time, we will see.

We don't know what steps were taken during the initial engine build to ensure the bolts were installed correctly.

However, I struggle to believe that if the bolts were loose or incorrectly installed from day 1 how it has taken 3 to 4 years for any damage to happen.

>>While the reasons you describe may be a potential cause

Yes, I am only talking about possibilities, and there are things I would investigate further. There are lots of unanswered questions about this problem, and therefore, I don't believe anyone who says they have a cure - we don't know what the root cause of the problem is yet, so, how can a cure be prescribed?

In my work, I have investigated a number of bolt failures, and the main thing I have learnt is the problem is rarely simple, and the root cause tends not to be obvious. On one project in particular, I learnt the hard way that in suggesting an engineering change before all the evidence and risks are understood can easily lead you into a worse position.

Of course, when you present all the evidence in the right way, the cause (and solution) becomes crystal clear - just like M. Poirot presenting a summing up!
Premature camshaft failure - Vol 3 - markandchrissie
Sounds to me like you'll never get a definitive answer - unless you have plenty of time and money to invest. If it was my car I would just check the bolts priodically, during a service for instance - if they stay tight between services, then you should be ok long term.
Premature camshaft failure - Vol 3 - Number_Cruncher
>>unless you have plenty of time and money to invest.

Yes, engineering investigations don't come cheap.

Vauxhall should by now have carried one out and understood what has caused the problem. Making this knowledge public would, however, leave them open to having to compensate people and rectify the situation, and they seem to be happier not to do that.

>>if they stay tight between services, then you should be ok long term.

I don't know. At the moment, we have no idea how quickly the situation progresses from all being well to bolts becoming loose to camshafts snapping. It might take 10,000 miles, it might take 500.

My 1.2 sxi 2005 corsa is on 39,000 and is a 55 plate.

I felt a sudden lurch as I was travelling to work doing about 60mph, the engine light was flashing and then the other dashboard lights were flashing, including the oil light, I quickly pulled over and the engine cut out. I tried restarting the car a few times before calling the RAC, it would start for a brief second and then cut out.

Luckily for me my boyfriends brother works for vauxhall. I broke down on the 18th May, he's been working on it for the last two weekends, it should be finished this coming saturday. The camshaft had snapped clean in half due to a bolt on the rocker finger coming loose. The 3rd cylinder wasnt holding any compression which ment that 1 or 2 of the valves were bent or broken. After 6 hours of taking the engine apart (including having to drain the oil and radiator), (the oil level was perfect and you could see that oil had been reaching the necessary parts). He found that only 1 valve was bent. For all the parts its cost me £330.

My car was 8 weeks over the warrenty, I brought it in april last year from a vauxhall dealer, so I tried my luck with them to see if they would do it out of good will, they said they would knock 30% off of the labour, but considering vauxhall charge £100 an hour for labour it wasnt worth it!
He checked out my chassis number as a certain batch of corsas were recalled due to the camchain snapping and other parts over heating, my car wasnt a recall.

I share everyones annoyance at this situation.
Premature camshaft failure - Vol 3 - dizzi30
Hi, it seems like I am joing a very long list of people who share the same problem, I was driving my mum's 55 corsa down the M1 yesterday afternoon when we suddenly lost power, I managed to get it over to the hard shoulder where we rang the AA, they came out and told us that the cam shaft has snapped. My mum has had this car from new and it only has 16k on the clock, it has full Vauxhall service history and after reading this web site we now know this is not an uncommon problem.
I would be gratefull for any advice on what do first and would also be willing to join any groups for watchdog or whatever it takes to make Vauxhall acknowledge there could be alot of potential ticking time bombs out there!!
Premature camshaft failure - Vol 3 - markandchrissie
Out of warranty, so Vauxhall won't want to know.

Take the rocker cover off (5 minute job with a torx socket) and see if the camshaft bearing caps are loose.

Hi
We understand your problem fully, but there is no quick fix, you can only get Vauxhall to fix the problem, and try to claim back all the costs after.
Refer to our posts, pete and ed Mon 6 apr 09 10.56. and after.
Get the Vauxhall garage to look at the problem, and ask the mechanic why does he think the Camshaft snapped,and also did he find any Camshaft Bearings loose!! if he did you must get this fact added in writing on his Vauxhall Visual Health check report.
Our small claims action, is in the final stages and we are waiting for Vauxhall to file their defence, but they are trying to settle out of court. So far we have been offered and have accepted a cheque for £1,177 which covers all that we had receipted invoices for.
Had a reply from watchdog, they dont want to know !!

Best of luck

Looks like you got a good result, Pete. Hope you get the result you're fighting for.

The question is, how did the bill come to over £1,100? You could buy a complete engine and fit it for less than that.

You can get reconditioned heads on the internet, complete with new valves, cams etc for around £200 - less than Vauxhall charge just for a single camshaft.


I think the reason people are reluctant to try and claim is the initial inflated outlay at a Vauxhall garage. There are many good garages out there who could do the job for a fraction of the price. If you are in doubt of getting your money back, you are not going to pay way over the odds - you just want the job done at a reasonable price.

Premature camshaft failure - Vol 3 - pete and ed
The actual amount received from Vauxhall was £1177.42 this included the following
1) Actual repair bill from vauxhall of £867.42
2) Private engineers inspection report which I had done - £225
3) Cost of initial Small claims Court Fee of - £85.

If I had not had the work done by Vauxhall I would had got nothing back, I believe the main point of my case was having the Camshaft Loose Bearing Caps stated on the Visual Health Check report.

Our Small Claims action is against Vauxhall Motors UK
Basis of Claim - Vauxhall Motors UK sold a new Corsa which was not fit for purpose.
ie. Loose Camshaft Bearing Caps were found and this fact was noted on the Vauxhall Visual Health check report.
Refer to our many posts, 19 March,6 April,and 11 April.
If anyone is to take the same action, I would suggest you change the wording as follows:-
Vauxhall Motors UK supplied a new Corsa to a franchised dealer which was not fit for purpose.
Premature camshaft failure - Vol 3 - pmh2
the legals on here will probably comment, but what contractual relationship did you have with Vauxhall UK that allowed you to make a claim?

I can understand it if you claimed against the supplying dealer.


or was it that Vauxhall just bought you off from creating too much trouble for them?

Paying Vauxhall's extotionate rate to have the car repaired - and having to spend more money on engineer's reports, filing a a small claims case etc - who's going to bother when there's no certainty of getting a refund?

A successful outcome here, but I don't think many other cases will get anywhere.
Premature camshaft failure - Vol 3 - nortones2
Perhaps there is a class action in mind? Maybe even VOSA might admit that there is a recall needed, before a fatal occurs where an engine cuts out and driver loses control, or is rear ended etc. Somehow I doubt it. The same problem as the judge in the ambulance-blocking lunatic case. Emphasis on outcomes, rather than risk.

Dear All, I am here to join the ranks of the Corsa camshaft breaking group. 2005 Corsa Breeze 1.2 50,000 miles, two vauxhall services.
Vauxhall are saying 'we have changed one or two but there is no problem with them'. Thanks to Honest John I find there is a major problem. I have given Vauxhall the go ahead to carry out the work but should I put them on notice that I want the parts and that I am going to make a claim? Surely it's time for a recall. All advice welcome.

Hi,

Last Sunday my camshaft snapped while on the motorway. My car is 2005 55 plate SXI 1.2 with 42000ish on the clock. AA man thought it may be a valve or valve spring. Turns out the camshaft has snapped clean in two and two valves also need to be replaced.

Drive (who the car is with) originally quoted 1150ish and have since dropped it to 927 as "they understand its a big amount to pay" or some crap like that. My service history is not full Vaux - only first service was with them and the second service wasn't bang on 2 years, also warranty was up nearly 9 months ago.

Im sure you all understand im not happy and would like advice from anyone who has been successful at getting all costs covered. Alternatively would be up for joining up if there is some sort of group action taking place against Vauxhall.

aussiemcaleer@hotmail.com is my email address if anyone could help.

My 55 plate Corsa decided to fail on me today whilst driving on the dual carriageway. Vauxhall said the camshaft has snapped and that it?s only running on 2 cylinders, they have quoted me £405 to fix this but are nice enough to knock off 10% LOL!

I would really appreciate if you could keep me informed of any progress on this.

I can only comment on our experience.
Book the car in to the Vauxhall garage,for them to do the repair, I am sure more damage will have been done, our final cost was £866. and this was less 30% the garage was able to get, but not every body gets the same "good will gesture"
As soon as it in the garage I suggest you send a letter of intent to Vauxhall head office (recorded delivery). They will only respond to pressure at the highest level.
In our case Vauxhall Head Office came back with a 50% "good will gesture"
Ask the mechanic at Vauxhall whether he found any loose Cam shaft Bearing Caps, if so this comment must be added to his Vauxhall Health check report.
If you do get this comment on the report, you are in a good position to get a 100% " good will gesture".but you may have to go ahead with the Small Claims action, Vauxhall will try to settle at 100% before it gets into court.(Court Fee £85)

With regards to our action, Vauxhall have sent us a cheque for £1177.42, which we have accepted, but this is only a portion of our claim, they have not paid for any travel expenses I had included. Because of this, I decided to carry on with the action and have payed a further £35 to file the court allocation questionnaire, We have been notified today that the Pre-liminary hearing is on Tuesday 11th August 2009.
I would still like to receive any info from anyone, with regards to their Vauxhall repairs ie. Copy of your Vauxhall repair invoice, Vauxhall visual health check report (Loose bearing caps) and any other info which may be of help.

Premature camshaft failure - Vol 3 - markandchrissie
There seems to be one common thread here... they snap while travelling at high speed. This suggests that loose bolts could well be the the cause as there would be far more vibration at higher revs and the likelihood of breakage.

If you own one of these (that hasn't broken!), spend a fiver on the sockets needed and remove the rocker cover and check the bolts are tight.

It's literally 10 minutes work. Probably best to have a new gasket to hand as well.

SQ - no need to quote the full message you're replying to

Well suprise suprise Vauxhall fitted the camshaft but then told me that one of my cylinders is out and that they will have to take the cam head off to investigate. They've come back to me today told me that 3 valves are damaged and that they also got in touch with Vauxhall head office and asked if they would contribute for "good will" but unfortunately although i have full service history I didn't take it to Vauxhall to get serviced. I've been told that this needs 8 and a half hours labour! They've told me that they are discounting some of the labour and that the final cost is £1107! I feel at a lost end. Can someone please give me some advice please?

My Mum has a 1.2 Corsa and last week the cam shaft went. Apparently the bolts had come loose. It is an 05 plate with 35,000 miles on the clock. She has been asked to pay £1,500 which was then reduced by the garage and then Vauxhall matched the garage offer so she's now left with a bill for £800. My Husband is a senior engineer and worked for a camshaft company for a good few years. He has told her it looks like an assembly problem in her case and that the cam shaft should last the life of the engine. Apparently Vauxhalls are known for this problem (they set up a dedicated line to keep up with replacing one model, which Vauxall did on the quiet at routine services) He has told her to get the cam shaft so he can look at it and go back to Vauxhall with a request not to pay and to mention his job and that we now have the cam shaft for him to look at. She is also going to tell them she is aware this is not just a one off incident and there are many people out there with the same problem. Be interesting to see if they back down and pay her off...

Premature camshaft failure - Vol 3 - **emma**
i everyone, i havnt been able to reply for a while but, my corsa is now fixed! after 2 cams fitted as both snapped, valves, pistons, head skimmed, the full wack. as the second cam went less than 24hours after i was given it back after the first one, the guy at the vauxhall garage said he felt guilty it happend again so what would have been over the £600.00 mark he only charged me £160 just for the cam and nothing else. as he said he was going to claim expenses back from vauxhall. although this has been on going for 11 weeks now, although i have my car back, i have still lost out on alot of money. other people have alot more than me but i will still try and claim it back, the only set back is that the garage would notadmit to the bairings been loose. nd im still also having an on going battle with the garage as i have been waiting 3 half weeks now just for a letter of the write up of what they have done.

I bought my 05 Corsa SXi a year ago from my daughter. At the weekend it suddenly lost power and sounded like a tractor. The exhaust warning light was on. Took it to a garage Monday - they have told me both camshafts have snapped causing something to come loose which has caused extensive damage to the engine. (Sorry I don't understand cars/engines so can't quote exactly what they said and it's still in the garage so I don't have the bill yet). They said it was very very unusual and they can't understand why it's happened. Having to have a recon engine fitted and the cost of repairs is £862.50!! It hasn't been serviced by vauxhall since I've had it so I guess they will disown any responsibility. But I would be very willing to add my voice to any and all approaches to trading standards, Watchdog, etc. I will ask for a written explanation of the damage if that is of any help. To say I'm furious is an understatement!

Pete,

Have you organised some press coverage for the court hearing?

Your local paper might be interested.

If they run something and there are subsequent hearings, you might get a bandwagon rolling - the story could be picked up by the local telly and others news organisations.

News-wise, your best point is that you are not just one bloke moaning about his car, but there appears to be lots of people with the same problem.

Premature camshaft failure - Vol 3 - lets work together
hi everyone
i bought a corsa 55plate last week from a garage and then read this forum.
i have decided to buy a good private car waranty to cover any mechanical/electrical problems that will no doubt arise. At the moment the general feeling seems to be the camshaft problem is only on 2005 models. My understanding is the twinport engines used on these models is also being used on the new models. Give it another 6months or so and you may find this problem on the 2006 models and then the 2007 models snd so on.

If I owned a potentially affected engine, I think I would be lifting the cam cover at every service and checking the bolts with a torque wrench set to the correct value. I would become concerned if I found any that moved - especially so if they moved again when checked some time / distance later.

Dear All, Vauxhall have denied any problem with the corsa camshaft but the garage that replaced ours, Eden of Reading, said the problem was only the front one. As if that makes it any better! We are going to go to the small claims court for the £500 odd repair so if anyone is prepared to send me the details of their car and the mileage at the time of cam failure I can cite those cases. The more we share our problem the less chance Vauxhall have of getting away with it. Graham

You do not have to strip the engine and rebuld, all you have to do is lift the Camshaft cover to get access to the bolts, about 30 min job and a new cover gasket.

sorry i cant be of any help. the garage told me none of the bolts were lose, but on my request they unscrewed them all and re-torqued them to the correct spec.
good luck in court. if there is not enough evidence given either way the judge will make a decision under the law of probability. for example who is more likely to be telling the truth you and all the other people who's 2005 corsa's have all had the same damage or a multimillion pound company trying to cop out of thier responsibilities.

My comment was "sarcastic" & not intended to be taken literally. Nevertheless the suggestion to check the bolts at every service would add about £100 to the bill. Its only anecdotal/backroom speculation that loose bolts are the cause of the problem and you can bet your bottom dollar that bolts will be over/undertightened and threads damaged by many garages.

So the advice IMO is rather silly.

I don't know where you're getting £100 from

Yes, there is no certainty about the root cause of the failure, I agree. But, checking the bolts can be done for the price of the cam cover seal at every service and represents a cheap and pragmatic step to take until the truth of the matter emerges.

I also don't see that thread damage is inevitable - in most cases, if the bolt doesn't move before the torque wrench clicks out, there's no wear at all.

So, I think your counter advice is rather poor.

You obviously live in a world where garages charge zero pounds an hour, and very little for parts and "sundries". You must have also complete faith in garage mechanics and their ability to use a torque wrench correctly (if they have one that is). You don't check the torque on an existing in place bolt by just using a torque wrench to "tighten" it. That is the wrong procedure and could easily lead to progressive tightening on each check. Not to mention, affects of block temperature etc.

So I think your counter counter advice is poorer.......;)


But what would I know as resident whipping boy?

>>You don't check the torque on an existing in place bolt by just using a torque wrench to "tighten" it. That is the wrong procedure and could easily lead to progressive tightening on each check. Not to mention, affects of block temperature etc.

In this case, simply setting the torque wrench to the right setting and applying it IS enough. If the bolt is anywhere near tight enough, nothing will move, and there will be no progressive tightening as you suggest. If the bolt is grossly loose, you'll feel the torque wrench move - which should set alarm bells ringing.

You still haven't justified £100 - where do you get that figure from?

>>But what would I know

I have no idea - why not tell us what you know?

Read my post.

But to make it clearer....

My experience of my Corsa at Vauxhall Dealer

1st service = £190

Request to correct overfilled oil (my mistake) = £75

I do not agree with your torque checking procedure. Bolts will typically show lower tension/torque after being in service for a while - this is accepted in engineering circles. Couple this with the hazards of uncalibrated torque wrenches, performance tolerance of torque wrenchs, torque wrench designs (those that allow to continue tightening beyond the preset value - i.e. most), and bad practice - never heard of that in a garage? ;)

If you dont have any other information other than an inital assembly torque, the correct way would be to loosen the bolt first and then re tighten. You then have the problem of what happens if the (soft aluminium?) block is warm, or you allow oil to flow under the cap/block joint.

To do the entire job correctly, IMO would take far more than 30 minutes.

Premature camshaft failure - Vol 3 - markandchrissie
£75 to correct overfilled oil?!

5 minute job... That works out at £900 per hour...


Premature camshaft failure - Vol 3 - brum
No main dealer garage will charge in 5 minute increments.

I challange anyone to actually go out and drain exactly 0.5 litres from their car and time it from walking out the room to cleaning up. 5 minutes?

Don't forget to fit a new oil sump washer......

And dont forget the time to make out the paperwork.

Lets get real folks......

It's a doddle with a Pela. Suck the oil from the dipstick tube - the graduations on the side of the bottle will tell you when 0.5 litres have been extracted. There's no mess, and no sump plug washer to charge for. 5 minutes, easy.

Vauxhall dealers, or, at least the one I used to work for charged out time in increments of 0.1 hours. 6 minutes - perfect! You were robbed.


Premature camshaft failure - Vol 3 - Number_Cruncher
OK, so the £100 comes from dealer pricing - as these cars are coming out of warranty, there's little point in paying a dealer to do this work. You've deliberately chosen the most expensive route to arrive at the price.

To take the other extreme, a decent torque wrench and a lifetime's supply of cam cover gaskets could be had for under £200, allowing careful DIY care for the remainder of the car's life - compared with the costs of camshaft failure, it's a no brainer.

>>I do not agree with your torque checking procedure. Bolts will typically show lower tension/torque after being in service for a while - this is accepted in engineering circles.

We must move in different engineering circles.

Yes, a bolt tensioned by a torque wrench will relax after tightening, in terms of the axial tension. There is also some relaxation of the built in torsion.

However, all of this is dwarfed by the difference between the dynamic friction which was applied as the bolt was tightened and the static friction which must be overcome to move the bolt.

As an example, if you installed a bolt to 8Nm, and then went away and had a cup of tea, to move that bolt anymore, I would be surprised if you didn't need to apply over 10Nm.

The simple procedure as written by me will not detect a bolt which has only relaxed a tiny amount, that's true, but, it will pick up on any gross relaxation, anything that's going to have serious consequence.

>>Couple this with the hazards of uncalibrated torque wrenches, performance tolerance of torque wrenchs, torque wrench designs (those that allow to continue tightening beyond the preset value - i.e. most), and bad practice - never heard of that in a garage? ;)

As I may have written on here before, of the sources of error in torquing a bolt, the accuracy of the torque wrench is the least of your worries, again, uncertainites in the level of friction will dominate - the scatter, either as measured, or as given by specifications like VDI-2230 when using a torque wrench is significant.

>>If you dont have any other information other than an inital assembly torque, the correct way would be to loosen the bolt first and then re tighten. You then have the problem of what happens if the (soft aluminium?) block is warm, or you allow oil to flow under the cap/block joint.


This is only true if you *need* to get back exactly to the as installed condition - there's no need to do that here. The only need is to check and correct for gross loosening. If the bolt is anywhere near being correct, it will not move when the correct specified torque is applied - static friction takes care of that.

If you don't want to venture into diy, then find yourself a good local garage or mechanic. They'll be far more consciencious and diligent than a main dealer. If the acne-ridden trainee leaves that all important bolt loose, he's not really going to care. To the self-employed mechanic, any mistakes will be at the cost of his livelihood.
Also, ignore the 20,000 mile intervals - stick to 10,000 at the most.

So?

You still pay what they want. Anyone who goes outside the dealer network for servicing within the warranty period will automatically lose any chance of goodwill, both within and outside the warranty period. Its an unwritten rule with manufacturers/dealers, and theres no law against it.

The vast majority of people who own a car would struggle to check the oil level, never mind service their own car. Advising people to get spurious maintenance ops done or to have their cars serviced outside the dealer network whilst in warranty may lead to some very unhappy people later on.

So what "benefits" did you reap from your main dealer servicing Brum?


A lighter wallet, updates to the ECU software that fixed major issues with engine stalling (but not all issues), a Vauxhall stamp in the service booklet, the perception (rightly or wrongly) that Vauxhall or the dealer couldnt squirm out of any warranty/goodwill claim, and the perception that if I sold the car that a Vauxhall history would mean a lot more to a buyer than a "Joe Blogs independant" or "I did it myself" history

As it happened, the car was written off and service history was checked by the insurance assesor, subsequently got a very satisfactory settlement. Probably the best thing about the whole Corsa experience.

Once out of warranty and if I was happy that I would not want goodwill, I would be the first to DIY. (I do service other cars that I and my son has myself). I was never happy with the Corsa and it would have been highly likely that I sold it at the end of the warranty period to mininimise my losses.

I was deeply unhappy about spending £190 for a glorified oil/filter change, but thats life.

No more GM for me, ever.

I've always bought cars at around 3 years old and run them for many years so the warranty and resale value have never been an issue.

Maybe I'm getting old, but modern cars are far too complicated and difficult to work on.

Remember the Mk3 Cavalier? Rust issues aside, with regular oil changes it would happily plod on for 400,000 miles.

What make have you sworn allegiance to?

Gone back to Skoda. Time will tell if I made a good choice. Decision was made based on my previous experience with Skoda - both the car and the dealer.

I must say that the Corsa has changed me - I no longer can get enthusiastic about cars - after almost 40 years of driving, I now look at them as just a tin box on wheels that cost me money to park on my drive.

Brum, I hope the Skoda will rekindle your enthusiasm for driving, given time. VAG cars are different to drive from Fords but in their own way are just as rewarding (as Fords are well-known to be). After only 3 months and 4500 miles I'm fond of my loosening-up Octavia already.

I've never owned a Vauxhall in 40 years of owning cars - and it's telling that I can't remember ever seeing any thread on this forum which was so enthusiastic about the joys of driving a Vauxhall that I have ever felt tempted. (*) I've driven them on occasions, but each time have felt a lack of that vital spark or 'zing' that distinguishes an enthusiast's car from one that just gets you from A to B.

And Vauxhall's attitude and lack of goodwill in what is clearly a common problem with 2005 Corsas is just plain stupid and will turn more customers away.

That said, I'm sure they make very sensible purchases if you're the second or third owner, some company fleet having taken a big hit in depreciation.

(*) Maybe a challenge for Dynamic Dave - a happy Vauxhall owner I think - to find one!

I wonder how many happy Corsa drivers are out there? OK my 99 Corsa Club now has 82,000 miles on the clock. In the past 1500 miles I have had to change four springs, a new back box and exhaust, new MAF sensor and three new tyres but its more due to the fact my standards are a lot stricter than what a quick MOT test will show up. I am hoping thats it now for a long time, though getting the coolant and brake fluid changed soon.

Despite its 82k it uses no oil or coolant whats so ever, returns 50mpg and is very sprighty round the city.

It is just nice to drive with very well balanced electronic power steering (I don't understand the comments about it being over light, I suspect people over inflate their tyres).

All the electrics work perfectly, the engine runs perfectly, its smooth, no miss fires, very good acceleration curve, it only really starts to slow down at 50mph plus. It is still on the original coil pack, lamdba sensor and all the other bits. Only engine work which has been done is a new MAF and a crankshaft sensor fitted in 2004 before I owned the car.

I am not moaning at VX about the work I have had done, its an old car it is to be expected. Springs do seem to be an issue though, never had any problems with Fords and springs.

However I am not sure I would buy a Corsa C, certainly not a 1.2 16v made between 2003-2005 anyway.

There is clearly an issue with camshafts, but on the Corsa site I am member of it is not a widely known problem. This is the only site which really seems to mention it in great deal and that is due to the google effect. There must be at least 100,000 Corsas with the 1.2 16v engine made between 2003-2006 and I suspect all the failures end up being told on this website.

My question is I wonder what the chance of the camshaft snapping on a C actually is? I am not denying there is a problem, just that websites like this can make it seem a lot worse than it actually is.

I first got interested in Vauxhalls when they bought the Astra and Nova out - at the time they were a breath of fresh air compared to other models at the time. They were so easy and cheap to work on - you could change a clutch in half an hour, for example, and you could always get parts from a breaker if necessary.

Apart from a 16 valve Astra which suffered a few head woes, all the Vauxhalls I have looked after for myself and family have been completely reliable, all seeing well over 100,000 trouble free miles with little more than routine servicing.

Modern Vauxhalls do seem to have lost that practicality, and I wouldn't think twice now about changing allegiance.

The fact is, all cars can and do go wrong, usually at great inconvenience and expense - something we just can't avoid. Yes, Vauxhall may have built a few dodgy Corsas, but you'll find that with any car. That's life!

Hi Brum - My first Vauxhall service was £143! The second one - £362! As you know, you have no choice if you have taken out finance with Vauxhall, it's in the agreement.

Good luck next week in Court Pete. I sincerely hope that as many people on the site as poss forward you plenty of documentary evidence. We must all stick together on this and stay focused.

If anyone is interested, I asked Vauxhall whether the bolts were ever modified. I have recently received a letter from Vauxhall stating the following:

I can confirm that prior to the production seizing on this model, we released a modification to the caps.

I will be taking out a small claims summons, but intend to get an engineers report first.

Please, if anyone has any documentary evidence, please forward it to me. Many thanks. Alison. greatheathmead@tiscali.co.uk

That is the most technically interesting piece of information on the thread. It would be good to find out what the modifcation was.

One possibility would be that the modified caps were made of a harder material to prevent the material under the bolt head from deforming excessively.
