Seeking Boxster mentor in Los Angeles area..

[adream8]

It was the AOS. It's diaphragm had begun to tear. Was sucking air into intake and creating a strong crankcase vacuum, substantially above what it should have been. Could barely budge the oil filler cap when the car was running.

Fortunately (and amazingly) there was no oil yet in the intake, so I was safe. And lucky.

Replaced the AOS, and now all the parameters (including fuel trim) are back within spec and the car is running perfectly. DO notice a difference in performance.

Figured I'd post, just in case it might help anyone else down the line.

Now I just have to change the oil and swap the engine mount out, and she'll be all fixed up.

Still open to getting together, if anyone's down..

These two jobs are fairly easy. But it could be fun to work with others.

And I can help with your jobs..

Let me know..

Cheers.
