Pressurized oil, whats causing it
 

So i am calling upon the knowledgeable to help diagnose a strange problem(s).

A friend has a 1995 bmw 318is which has recently been stalling. We believe it is stalling(cutting all power even under throttle and dying) due to a faulty ECU which pre-obdII bmws had problems with.

We had the car running and opened up the oil filler cap and it was blowing a constant stream of air:confused:, as if you had put your hand behind a tailpipe.

Has anyone experienced this before? if it it wasn't on an audi

bump ^^^

really curious on this one, need to have a solution by next week

nobody has an even an opinion on this?
