'85 5KT oil leak problems ...
Some of you may remember my post earlier this
week about an oil leak that started on my '85 5KT (147K)
after I fixed a vacuum leak. Scott Mockry had many
suggestions which have helped narrow things down a
bit, but the leak continues. I decided to post once
more, just in case anyone else has encountered this
problem. So ....If you'd like to help protect a
fellow Audi-nut from wifely ire, read on ...
Engine: KH (non W/C turbo, almost identical to MC).
1. Long-standing vacuum leak was causing
gauge to read no less than 0.8 bar and no more than 1.2.
2. Found rotten hose connecting manifold to ECU,
replaced it. Engine suddenly very happy, boosts upto
1.5 and into fuel cutoff. Owner even happier.
3. Return from somewhat spirited drive to
find pool of oil collecting under the car. Major leak
from oil pan gasket.
4. Replaced gasket, leak remains, but less severe.
5. Tried all the following, without success:
-Disconnected ECU vacuum hose.
-Checked for crankcase breather hose
-Performed dipstick and filler cap tests --
engine stalled in both cases.
