[s-cars] Oil in crossflow pipe.

[Lino M. Valadas]

My 93 S4 with 170K  km at the moment, has since I bought it with 120K km
deposited a considerable amount of oil in the crossflow pipe.  I tried an
oil catcher for a while but it didn't catch any oil.  My compression is good
on 4 cylinders.  My #1 is down about 20 lbs/sq inch from the other 4.  Still
within spec. per Bentley.  The car is stock.  I get 2.2 bar of boost on the
digital display. Power feels normal.  The amount of oil in the crossflow
pipe appears to be directly related to how hard I drive the car.  the harder
I drive the greater the amount of oil.

I know this issue has been discussed before but I would like to know if
anybody has been successful fixing it.

I suspect: 1. Bad turbo seals.  2. Bad piston rings.

If you have been able to cure your oil in crossflow pipe problem, please let
me know I'm getting tired of draining it.

Thanks in advance.
