VW Passat 95 N reg. 1.8 petrol
My Passat has started to run slightly rough. A bit fluffy on tick over. Takes two tries to start, not usual one.
Thought I would clean and gap the plugs.
Does anybody know what the gap should be?
Thanks for your help.

Not off hand, as mine's a diesel.

My Haynes manual covers all 4-cyl variants (petrol and diesel) so if no-one else has provided the info by the time I get home tonight then I'll look it up for you.

Thanks GrahamF1
When I got the car, I said to myself I would not get a Haynes manual as I wanted to have a modern car maintained by professionals...not bodged by myself as my Herald is.
However, I can't resist getting the bonnet up this weekend!

A fellow Triumph owner!

Believe me, having 'professionals' maintain your modern car isn't all it's cracked up to be! Astronomical labour and parts charges, 'necessary work' magically appearing, etc.

That have you got?
Mine is a 1969 13/60 Herald convertible.

Are they multi-electrode?

If so, they don't need re-gapping.

I feel like a dinosaur...
Not taken them out yet, so don't know if they are multi-electrode.
I guess people don't clean and gap plugs anymore. Just replace them.

Mine's a 1972 Mk IV Spitfire. Currently SORN awaiting a new manifold, exhaust (might just buy a stainless system right through, what do you reckon?) and transmission tunnel cover for the MOT. Plan to MOT it over the Easter weekend.

Plugs could well be multielectrode. I can't understand why people throw away perfectly good plugs instead of cleaning and re-gapping them. Seems £20 for a set is cheaper than 15 mins of someone's time these days...

When I had a Vitesse, I fitted a stainless exhaust system from the Triumph Sports Six Club. It fitted well, was good and noisy, and was still on the car when I sold it many years later.

How much did it cost?

I've got prices of £300 from Canley Classics and £350 from Quiller Triumph (including manifold).

I presume you two Triumph owners already know Rimmer Brother in Lincoln.

www.rimmerbros.co.uk/

They have a very good reputation.
Plug gaps VW Passat - GrahamF1
Heard of them.

I'm fairly new to Triumphs, and the guy who I bought my car from told me to steer clear of Rimmer Bros - said that they're expensive and unhelpful.

Can't comment on the unhelpful as I've not used them, but from their catalogue they are certainly quite expensive. Canley Classics (Coventry), Quiller Triumph (SE London) and TRGB (Somersham, Hunts) price much more reasonably, even if they do lack the 'showroom' feel that Rimmer Bros seems to project.

The TSSC club sells a semi-sports stainless exhaust system including downpipe for a MKIV spit at £185.
I would recommend joining. They have a good insurance scheme (£110 year) and an excellent monthly magazine, lots of events, traders etc.
Have a look at www.tssc.org.uk.

I have had excellent service from both Canley and Rimmers. TRGB have also been very helpful in the past, but they are really focused on TRs. No experience of Quillers.

There is a guy called Bill who runs www.rarebits4classics.co.uk who specialises in hard to find bits and second-hand parts. He is really helpful and knowledgeable.

Chris Wittor (advertises in SixAppeal) is the man for advice and bits. He does new stuff, has a vast stock of secondhand at very reasonable prices, and remanufactures hard to get bits. Covers the 2000 anyway, not sure about other models.
My experience of Rimmers is that they are good on the things they do, but not very knowledgeable once you stray off into different fittings for different chassis numbers. They are good at returns though if they send the wrong parts.

I agree up to a point about cleaning old plugs. It's OK for older models, but I think modern electrical systems are more critical. I've had plugs that looked perfect to the eye but had a mysterious missfire.

Chris Wittor is a 2000/ 2500 specialist only Oh and polybushes for all makes.
Rimmers are expensive and of variable help although currently have loads of specials at the mo certainly for TRs. Think they employ ex garage storemen which tends to be a pain as with most others you talk to the guy who fits bits rather than just a storeman.
For new bits Quiller in Plumstead are good as are TD Fitchett who advertise in the classic mags. Moss very variable on price and heard things about some of their quality, the Spitfire Graveyard in Sheffield are good for s/h bits. Not used Jigsaw racing but heard good things. A lot of people use Chic Doig in "Sweaty Sock Land". Worth buying one of the low end classic mags for ads from suppliers.
A lot of people fit the exhaust from TSSC as its very competitive. Make sure if fitting a stainless exhaust you uprate the rubber hangers with Polybush ones the extra weight of a good s/s soon knackers the standard rubber ones.

As regards the plugs I'd replace, if they track HT then they can destroy electronics so generally not worth it.

I've just checked Rimmer Bros and they do a single pipe sports system with a twin-tailpipe backbox and a four-pipe manifold, all in stainless, for just over £300. Might pay them a visit.

TSSC can't really get near this. From the prices I can see how the TSSC semi-sports system would appeal if you didn't need a new manifold.

seems like a long time since I have done this but think the usual plug gap was 25thou but from memory the standard tool to set gap was a used hacksaw blade instead of feeler gauge

I always thought it was between 28 to 32 thou (0.3 to 0.4 mm)
Plug gaps VW Passat - defender
see cliffs posting on the other thread on plugs ,I only read it after posting. according to autolite plug tool 30 thou =0.7mm but also measured hacksaw blade and it is 27thou

Damn! I've previously got the mm measurements wrong before on here.
www.honestjohn.co.uk/forum/post/index.htm?t=9725

What I meant to have said was 0.7 to 0.8mm.

Sorry, I'm trying to have the same conversation in two threads at the same time.
My point was, yes I do clean and reset old plugs, but only on the old Triumph. I think modern systems may be more critical.
I do take care to set to 25, or 32, or whatever the particular book says (in emergency a hacksaw is pretty good) but I have never known whether it really matters. Maybe 25 gives an easier spark but 32 a snappier one?
