Oil Around Plugs

[steverrquattro]

Hi,

Just bought an S2 and trying to get to grips wiyth it today while the Mrs is out.

Bsically there is an oil leak around the back of the engine and from what I can see someone has been using a gasket sealent which may mean the rocker gasket is U/S.

So whilst starting to remove various components I noticed that there is oil in the bores where the pulgs are. Will this also be leaking through from the rocker cover gasket?

Yes, there is an internal gasket to seal the 5 spark plugs.

Thanks again Andy. I was beginning to panick a bit for a moment as originally I bought the car for the engine to put in my SWB car................but now I'm sort of thinking of putting it back on the road as it's too good to scrap.

You need item 17 in the diagram below. This includes the cam cover edge gasket, two half moons for the firewall end of the cam cover and the integral 5 spark plug well sealing gasket. Incidentally, last week I saw a running UrS4 that had so much oil in the spark plug wells (all 5) that the coil to plug boots were totally saturated. Car still ran (go figure). Nevertheless, you should buy and install the gasket set (pretty easy, 30 min job, watch out for the No. 19 (10 mm) bolts that also hold the cover down to the head. 15 Nm torque on everything (IIRC))

Cheers guys, much appreciated.

I've removed the rocker cover today and there was gasket sealant everywhere. The main gasket was in several pieces as was the one around the spark plugs.

At least I know that's what the problem is and it's a simple fix.

First thing is to buy the new cam cover gasket kit. When you remove the old one, you will naturally have to remove not only traces of the old gasket but also the bodged gasket sealant traces. Given that a previous owner didn't do it up properly , you *might* find some other surprizes as you dig into the car. Just be prepared.

Exactly what I thought. I've been here before with UR Quattro ownership. That's why I always say with an old car it's more about the most recent service history and current condition rather than for example the £10K it had spent on it all those years ago.

Does that cam cover have metal tubes sticking out of each plug hole?

Ignoring the gasket that cylinder head looks nice and sludge free to me, somebodys looked after it and done regular oil changes

It's some kind of silver paper. To be fair to the previous owner he did tell me he'd done this but at the time I didn't quite understand what he meant.

The car has a full Audi service history so at least it's had regular oil changes which is the main reason why I bought it.

Looking forward to fitting new gaskets this week and getting it running again.

Hello, with a new cam cover gasket kit is a good idea put also a bit of sealant or not?
Thanks!

The only place a bit of sealant should/could help is at the back, at the half moon(s) where the rifle drilling of the cam caps pierced the head. High Temp RTV is what some people use to make sure the half moon(s) stay in place.
