Blowing LOTS of smoke

[Gelbster]

You got the answer in Post #2
Forget your Boss and the cylinder head gasket
If you want the names of some Porsche M96 Indies in Vegas ask here.
Taking an M96 anywhere else is umm ....silly.

Typically an AOS failure does not hydrolock an engine very often, although it is possible.
In retrospect I should have shutdown immediately and got a tow home just to eliminate the hydrolock potential as the cost/risk ratio is too high to take a chance.

I drove a couple miles billowing tons of smoke and there were no serious side effects. It looks spectacularly bad when most cars blow that kind of smoke but is not that big a deal really for a Boxster.

We have all learned to hate the AOS after such an embarrassing event.

When it happened to me I had already read about it so I was not overly stressed and I actually started laughing at the ridiculous amount of smoke I had generated, literally blacking out a good 100' behind me and the terrified look of other drivers passing by.
Lost about 2 quarts of oil during that failure.

I simply replaced the AOS and everything was back to normal.

I would get a 2nd opinion on the blown engine theory from a proper Porsche Mechanic.

I spoke to the guy again and asked him about the AOS. Dude said they checked that first and it was dry. He wants to start a complete engine teardown to find out exactly what the problem is but just that is gonna run me three grand. The mechanic does a lot of work on european cars and has done work on my porsche before. The things he fixed haven't broken yet.

Ask him what vacuum level did he read when he test the AOS; if he says he did not check it, or has no idea what your referring to, be very afraid and take the car somewhere else...........
