I have a high pitch wine sound on my 2000 carerra c2/c4. I was told it was the oil separator. The oil cap was almost impossible to remove while the engine was running. When it was removed the sound seemed to stop. Does this sound right?

Do you have white smoke on start up or at high RPM's going around corners? Check your throttle body (around the butterfly) for any oil. These symptoms as well as the extreme suction with your oil cap are all definite signs of a bad AOS(oil seperator.)

Do a search (AOS) here and you will find a lot of good info

Don't know if this will help but I had a high pitched whine and it turned out to be my alternator. With my engine running the force required to remove the oil fill cap is higher than I would expect so I assumed AO separator. However, pretty sure it's not as no smoke on start up and nothing in the intake.

If it is constant -- might be something else, but on start up I believe it is the AOS (air oil seperator) -- Mine has a nice whine until the DME decides

to lower idle (3.2S Boxster)
