If it is tied to your driving habits then you still need to find out what is wrong. I drive mine hard every day, and it never smokes. There is something not right here. It may be as bad as you thought, but you need to have it checked out.

 

I have a 2002 996 C4 and it will this the next morning on startup after spirited driving .
Now has 117k miles on it and still runs great 😄

 

I'm in Toronto. Just changed my oil from Mobil 1 0-40 to Motul 5-40. My engine sounds quieter and I just feel better after reading lots of good stuff about motul. Try a fresh oil change.

 

id check the oil level first, might be overfilled

 

Yes, oil level may be the issue.
I just had an oil change ( while having the ac evaporator changed...very expensive )
Today: no smoke on start - up.
If I drive aggressively , i am pretty sure I will have a puff of smoke the next day.
The oil level is near the top of the dip-stick.
Generally, if you do some track driving, they say you need to keep the oil level at mid dipstick level.
Boxer engine etc.
It just feels soooo gooood flooring that thing off and on :-D

 

this thread is 2 years old, i'm guessing he found the problem

maybe he could post what it was

 

let your car idle for a minute or two before shutdown after a hot drive . you will not get as much smoke the next day .

 

Try allowing the engine to idle for a full minute in a level parking spot before turning the engine off. This allows more of the oil to be pumped out of the heads & returned to the sump where it is less likely to get past the rings.

 

Are you parking on a hill/inclined driveway? If so, turn it around and park the other direction and see if that helps - or park on a flat surface. I've seen that after parking on a hill tail down.

 

I park on the level.
The idling idea seems to work.

Incidentally, I had the same thing on my '89 911 Targa off and on.
When I use it driving normally on my work commute its not a problem .
