Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have a 3.6 2002 c2 and it has always smoked on start up and during a heavy drive(track days etc) lots and lots of smoke!
OPC say no problems and car drives well, does anyone else get this?
Jon
The 996 tends to smoke a bit when you start it up. Especially if you have driven it hard on the previous drive.
So long as:
a) the smoke is white and not black or blue
b) it doesn't cough or splutter at idle
c) your oil level is at top bar on the dash display when the engine is hot and on a level surfice
.....then I would'nt worry about it.
It always smoked as you say on start up but will smoke during haevy track work, when it happens people think I have blown the engine. It is worse since I fitted Free Flow silencers!
We watched a smoking (and occasionally misfiring) 996 C2 at the June Castle Combe track day. Apparently, the owner was advised to stop but carried on until there was a big bang and lots of smoke as he did a Takuma Sato impersonation coming into the pit straight! Not very encouraging for us other 996 owners. Some people think you are asking for trouble if you track a regular 996. Well, what the hell did we shell out all that money for? Have Porsche really lost the plot? If the unhappy tracker reads this, could he advise us what happened to his engine...is it anything we can avoid?
A puff of oil smoke on start up is regarded as "normal" on many Porkers including the 996, BUT I certainly don't think it is normal for the car to smoke during driving, particularly to the degree that you have mentioned. I would definitely get your engine fully checked out at an opc or good independent.
Thanks for the quick response Richard.
Hard to tell really as saw it in the wing mirror - bluey grey I would say.
The car was serviced recently and the oil level indicator at start is showing full but I haven't checked on the dipstick - will do so tomorrow.
The car doesn't overheat or use any water and the water does not appear oily.
Could this be rings?
Unlikely to be rings, or it would be doing it most of the time. Check the oil level first. If it is OK, a good test for a failed AOS is to remove the inlet hose to the throttle body, open the butterfly, and look inside. If it is coated with an oily film, it is likely to be the AOS.

Thanks for the tip Richard.
Checked the oil level on the dipstick and seems ok. Pulled the hose off the throttle body and there were signs of oil so its going in to have the OAS changed. Hope that solves the problem.
Thanks again
