What did the mechanic tell you he was going to do for $4000 - $5000? Or was that based on you pulling up in a Porsche and telling him it smokes?

I think you're going to hear a number of "start with the AOS" replies - it's a likely culprit and relatively cheap to do, so why not cross it off of the list of suspects?

Jake - if you're reading this - didn't you chime in on a thread recently about using a catch can instead of an AOS? Anyone know what ever became of that idea?

Dude just replace the AOS to start. It's only $100 from Sunset Imports. Couldn't hurt.

I plan on replacing my AOS this weekend, there is a great write-up with pics on the forum.

For what it's worth, I recently had my oil changed from 5w 30 to 10w 40 (by Jake) and it resolved by smoke issues.

After the smoke clears, does she run good? If the answer is yes and the oil and coolant appear as normal, not corrupted by each other, I'd certainly cross off head gasket.

Well I'd say it's the AOS, make sure you don't have the oil overfilled as well. BTW, regarding the AOS, even when that device is new the box engine is going to puff smoke, it's inherent in the flat six layout. Since we all own regular vehicles that only smoke in cold weather, my theory is we are overly sensitive to Boxster smoke because no other cars really do that, just my two cents.
