Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

car felt the same, i even set my best time on one of those laps at 1:45.
Leading evidence: 'Set best time' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Set best time' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

That probably didn't help him one bit, but it sure was funny!!
Started my car yesterday(cold start) and white smoke came out the exhaust.
Has never happened before. It didnt happen this morning, but it has me concerned.
Anyone have an idea what causes this?
A little smoke on start up is normal for a "flat" motor. Oil can accumulate in the cylinder walls rather than drain (since the cylinders are horizontal). This oil will burn off when you first start the car which will cause some brief smoke.
My cars only do it occasionally, but it does happen. It is a fairly common question on the board.
Yea it will. Can't tell you when but it will. I happens more often to me at the track after the car has been driven hard, then restarted the next morning at the track. Some times it does it, some times it dosen't. Happens once in a while at home. Everyone I have spoken to, including the dealer, says it is normal. I am not worried about it.
Same here, usually happens at startup afer the last hard run.
Then it goes away at the next startup (or next few days) after driving it for a while without pushing hard.
In fact, I notice mine has more smoke come out of the passenger side exhaust than the driver's side.
Wonder why...?
If I start the car and run it for a very short time, then park it overnight, I get white smoke when I start it the next time. This usually happens if I pull the car out of the garage, wash it, and put it back in. On the other hand if I drive the car around the block after washing and drying it (to blow the water out of the crevices) then there's no white smoke the next day.
Michael,
I wouldnt be to concerned as it does occur, for me its when she sits in my garage for over 4 days. Usually on start up it occurs then next day it will be fine.
I like the Pope theory. I need to look back as I start mine - I've never noticed any smoke, but then again, I'm too busy being enthralled by the sound of the flat-six roaring.
In reality the white smoke on start-up is largely ceremonial. Every 911 does this from time to time to celebrate the year that it took to produce them.
Riad gave a good description of the process.
9900 miles - I get white smoke for about 2 minutes on a cold start when the car has been sitting.
White smoke seems part of the Porsche experience - I used to get it with my 1994 too. As long as it goes away after a few minutes, it's no problem.
You've got 75k on your Cab? It looks great in the avatar....
White smoke for 2 minutes is too long. Typically a short burst of smoke on startup is normal, maybe even up to 20-25 seconds if the car has sat for a period of time. Anything longer than that, and you start suspecting a bad oil/air seperator.

doc, if oil/air seperator is not fixed, what will happen?
i get the occasional, normal white smoke unpon start up, uusally after 30 min of track session then parked for another 30 min.
but i just noticed i get large puff of white smoke at tight 60mph left hairpins, like T2 at laguna seca. it occurs just when i shift from 2nd to third. is this normal, ok, or something is broken?
car felt the same, i even set my best time on one of those laps at 1:45. (cayman S)
