From Audi 100 to urS4 in a week

[hunker7]

I filled the tank before 358 mile trip, and filled it again today, and consumption worked out at 8.7 l/100l which is 32mpg (doing about 80/85 mph most of the way+wasn't only motorway), which is good I guess? The trip computer said 28mpg

ALSO, I think the floaty thing in the tank isn't working right. Before filling up, tank was very very empty (I thought I won't make it to the station) and only 66 litres went in.

ALSO, is there a way to calibrate trip computer?

Thanks nightshift Dave.

Dayshift Dave usual hours are 7 AM PST to 12 midnight PST (UK is 8 hrs ahead) and last night it was 2 AM (night out) but I missed that post and am late for work this AM.

By the way Hunker7: Most of what you need to know about your AAN is found here (click on the pertinent label, in this case PCV system):

Just a thought, are you sure the PCV pipes are clear and no holes and the 2 valves are working? If you havent done it yet I would take the pipes off and wash them out and replace the 2 valves.

Good point. On a meet a couple years back there was an S2 that started smoking because of a full catchcan. Blocked PCV would result in the same problems I think?

Thanks, Dave! I'll start with that, thanks

What do they look like and where do I find them?

Just went out and checked the oil level. After 140 mile drive no change in oil level, started up, and blue smoke is shooting out of the exhaust. So if it was the turbo, then I'd have blue smoke all the time, and oil consumption would be high in city and motorway driving.

I am not buying an engine!!!!!!!!!

Fine with me

Hope you will be able to fix the issue without taking the head off

[Bowie69]

Be sure it is valve guides/seals....

I know from experience that seals are just a patch job, and actually it is the guides that need doing.

Also...

At that consumption I would be looking elsewhere, 100 miles for a litre of oil? I would be looking at a turbo personally.

Hoses off and have a look.

My guides needed doing years back, just replaced seals, still smokes now, but does about 4000 miles/litre, and that's with a crank seal that's making the underside of the engine look like the Exxon Valdez has made a showing. (new year job).

tonks4x4 has one that works on the 20vt, might be worth asking him the model.

This kind of thing

That looks interesting. Definitely worth a consideration, as rest of the work involved is unnecessary. Will ask Tonks nicely, maybe he can let me see the magin tool

How are the kits called, could have a look. As that could work out cheaper, than full gasket set + skimming.

[andy10v]

You can do it in situ, there are a few kits, compressed air into the spark plug hole to hold the valves (or string if you want to be ghetto) and a lever valve spring compressor that bolts to the head.

[hunker7]

Do you think its the valve stem seals?

You can get a head gasket kit for ECP, GSF, local motor factors, quattro corner etc. Just make sure its a MLS one. Victor Reinz seem to be rated on the forum.

You will need new head bolts (stretch)

I am quite sure it valve stem seals. On long drives levels don't change, around town, 100 miles and it's below minimum. Also, on cold start, blue smoke coming out.

You can change stem seals without taking the head off.

Is this one of those engines? Dad told me that can be done by holding the valves through spark plug holes, or something like that?
