just purchased a 99 911 carerra and no issues. Had it looked at my a local porsche mechanin and he suggested oil change okay....so I took a leap of faith and only on high rpms ( 85 = MPH) when idle smoke..smelss like oil burning is coming from engine and conduit where it connects tio spoiler? any idea would be great

 

I vote AOS gone bad.

 

+ 1 on AOS also.....is there smoke coming out of the tail pipe when start up?

 

Both tailpipes.?

 

Spirited drives will heat your rear tires up pretty good. Oil / rubber smell always made me touch and feel the temp of the rear tires...

 

did not notice any smoke from pipe

 

not even after resting all night from a spirited drive I smelled smoke and saw it come from the vent in engine

 

You bought a 996 and had no issues.
You had you mechanic do an oil change.
After the oil change, you have smoke coming out?
Am I reading this right? Possibly oil overfill or spilled some oil in you engine compartment as you're stating its coming up from under the hood.

 

yes correct after two weeks of driving I would assume oil if spilled would have disspated but after after driving hard and idle or parked and next day turned on the smoke was apparent on the left side coming from engine and conduit to spoiler

 

Plastic oil fill tube leaking oil onto engine ?? Check your oil level & check how much oil your mechanic charged you for.

 

9 quarts of oil

 

Here is a definitive DIY test for a busted AOS:

just for grins, have you checked if its overfilled after the oil change?

 

When mine was overfilled it didnt smell like burning oil.

 

mechanic says AOS good, no overfill and maybe the coolant was too high????
