Well, yesterday I took the Audi back in for its retest - it failed onanti-roll bar bushes, one CV boot and front discs, so all easy things tocheck, and got quickly checked over and a new ticket handed to me within acouple of minutes.Then I asked how busy he was today as my newly-bought Seat Inca van iscoming up for its first MOT - h

Yup. It wasn't having any effect on my performance. I just had to top the engine oil up every week. I left it a month or so at one stage and had put

2.5 litres in (oops!). The main thing it was hurting were the people who got caught behind me in traffic. I found the only way to prevent masses of blue smoke if I got caught up in slow-moving traffic was to keep the revs above 2000 rpm. Dunno about anyone else, but whenever I've taken my car for an MoT, the testers leave the engine running on idle the whole time during the test - kinda a worse-case scenario for my engine.

Not too difficult, but does involve pulling the cylinder head off.

Really? Blimey. Most of the ones I've seen in the flesh (old stuff mostly) just have a plastic disc on the top of the valve guide.

Fairly easy on my pushrod v8, just lift the rocker shafts and push the seal down over the valve stems. With overhead cams you'd have to release the cam and try not to let the chain / belt slip, to do the same thing.

Are the seals on the bottom of the guides, then, or what? :)

I'd have to go and have another look to be certain, but it just seemed impossible to get to the seals from the top of the cylinder head. The Haynes manual doesn't say it's possible (in itself, not total proof of course!), but I've had the whole head off at one point in the past and then later, wanted to renew the stem seals in order to pre-empt what I thought was going to happen (and did) and just couldn't do it without getting the head off again. So I gave up and waited for it to get really bad ;)

If anyone would care to tell me how it is possible to change the stem seals on an XU9 engine without taking the head off, I would of course be more than happy to hear about it ;)

Chris.
