Question about Audi 90
As a general rule if this occurs then the valve guide seals are worn. (Located in the "head") of the engine block. Usually requires a "head" job by a mechanic.
You may also have excessive wear on the piston rings
and bores. This can be checked by having a compression check on all cylinders to
see if it is within specifications.
One last thought. If the PCV valve is failing this may occur as well. (Positive crankcase
ventilation). An inexpensive part, They can usually be checked by removing them and
blowing into them but I generally just replace them (generally less than 10 dollars).
