Why do you open the bonnet? - CL Grease

And what do you check?

I grew up with motors in the era of rotting hoses and worries about oil levels. Remember that feeling of an internally collapsed top or bottom hose? You became quite a specialist in palpitating the rubber - from different angles and in different places. A sort of `Doctor of Rubber` award should perhaps have been on offer from Dunlop - but you never got one.

Just hands that smelled of antifreeze and rusty hot water in bed....

Now you`ve got a modern motor - it`s forty years on - when did your palpitating award last pay off - and can your brain still formulate that rotted rubber and hot rusty water smell?

Do you think they`ve overdone it - taking the fun out of bonnet opening?

The bonnet of our car is locked need a key to open it.Had a look at the windscreen wiper water level,oil level.Everything else is covered up.Cars are becoming computers on wheels.Sealed engines next.

I'm not that trusting. Coolant level has dropped when a VW radiator corroded through, I also check washers, engine oil level and brake fluid regularly.And remove leaves etc blocking vents and radiators. No coolant hoses are visible in my Skoda engine bay, so I miss that udder like squeezing of my old A series pipework.

Just bought my 17 year old a 2003 Punto...

Quite enjoying my visits to Halfords and tinkering with it. So far I've replaced a boot strut, removed the battery and charged it (I knew that battery charger would come in useful again some day !), changed the wipers and just started to touch up the paintwork.

I must have got carried away, as I finally lifted the bonnet of my 5 month old IX35 at weekend....just for a look and to top up the washer fluid though.

Hello old friend.

There's still plenty to keep an eye on under that bonnet, hiding the workings with pretty plastic covers doesn't make them any less likely to fail with the passage of time. Even more important now as many new cars don't have a temperature gauge any more and an oil pressure gauge is almost unheard of, not as modern driver would have the foggiest idea what to look for.

The really important place to check for rubber degradation though is underneath, yes that place modern motorist doesn't think exists, even notorious maintenance enthusiasts.;) have gone over to the dark side and bought themselves Pela pumps to suck oil out of the blessed dispstick, wher they'd have donned overalls jcked the old girl up and had a perusal whilst said oil was draining.

So few if any have a good poke nose underneath, they never see of feel the brittleness of the drive shaft boots, they don't bend the flexible brake pipes and check for perishing, they don't notice the cracked bottom ball joint cover either, living under this manufacturer created illusion that everything modern is so wonderful.

Mind you to be able to have a nose underneath would mean hosing off the crud and salt of all previous winters first, ignorance is bliss..;)

"Sealed engines next"....

Common sense dictated that my R-reg. MGtf had an engine but there was little other evidence and apparently no way of seeing it. I asked the service manager at the dealer how to gain access. "What do you want to do that for?" he asked. I did not want to admit to idle curiosity so said it was to get at the spark plugs. "What on earth do you want to do that for?" he asked. I said, to clean the points. You've guessed his response. I said, well, I suppose they have to be cleaned from time to time. "Maybe every 60,000 miles", he conceded but his expression forbad any further enquiry. I can imagine him having a good joke with his mechanics about me later - "There was this bloke in here who wanted to see his engine!"

I never did get to see it.

A nice story bintang write a book about it be a bestseller people from the past who want to see a engine.Iam curious like to talk to mechanics or engineers.Used to do bits and pieces to the old beetles i had,putting grease in the front axle.

IMHO opening the bonnet should still be a monthly routine at least. My Suzuki has had two oil changes a year, but has never been topped up in between. Too easy then to not bother looking, you may say. I recall a post on here though, not too long ago, where the owner of a VW diesel engined Skoda found that his oil lamp would not go out. This was due to dangerously low oil level, and the car was trailered away for a check out. Having a 20,000 mile service interval, doesn't mean they all will make it without owners attention. Indeed, I think some OEM's rely on the regular top ups required, by some engines to bolster the oil quality to acheive the long drain intervals.

That reminds me of reading a forum over on the other side of the pond recently. A car owner was going to great trouble to assess the quality of his engine oil as the miles mounted. A very professional attempt over around 10,000 miles.

Of course that`s considered by some in the US to be an incredible mileage between oil changes. It was the best, Mobil 1 too.

He sent samples off every so often and there were charts of wear metals and so on. Then I noticed his top up schedule. Six `quarts` (whatever they are;-) had been added in total...

There was no comment on that and everyone seemed to regard it as normal.

You had this mental image of `consumption` of gas and oil - a relatively new US motor built to 1940`s engine clearances.

Frustrating really - the tech interest i had in the oil holding it`s quality - negated by this constant flood of new oil being poured in the top. I was left with the thought that, on the `king Arthur`s axe` principle - that the oil would actually last forever with just filter changes - but again no one had twigged that.

Well.. I know not really.. Wouldn`t want the odd `perpetual` sump molecule, turning to sludge ;-)

..and that reminds me of the wonderful description in 'Grapes of Wrath' of a famine-struck dirt poor family nursing their overloaded truck to the west coast - and changing a big end by the side of the road with little more than a hammer and spanner....
