Mr. Brown

After I run the car hard on the track I park it until the next session.
Upon start-up, there are huge billows of white smoke coming out of the exhaust, and that lasts for about a full minute. When it first happened a few months ago I thought that perhaps the oil was over-filled, but that is not the case.
Can anyone shed light on what the problem and fix are?
TIA,
Mr. B

A little bit of white smoke is okay. A lot (and it seems like you have a lot) could be a faulty oil separator. Take it in and let us know what the diagnosis is.

My 05 997S did just that. I now keep my oil level down one bar and it has not happened since.

This seems to be a relatively commonl oocurance after driving on the track. You might try letting the car cool down prior to shutting it off. If it has been driven hard, you get a little oil seep. Running the car for a couple of minutes after exiting the track will help reduce/eleminate the white smoke on the next startup.

If that doesn't stop it, then it could be your oil separator.

I've noticed a lot of production cars need to be 'run' on a cool down cycle as oppossed to just turning the car off hot. Might work?

My 996 would do that at the track but not anytime else.

Mr. Brown

Did any problems ever crop up?

No, I would just have to add oil after a track day.

That's why you run a "Cool Down" lap at PDE (and for the brakes) - cool her off and you will notice almost NO smoke after a hard run...

Mr. Brown

That's good advice.
I appreciate it.

Exactly right - mine did the same once - when the session got red flagged and we had to pull in without a cool down lap - it smoked on next start up . Never again since as now I always let mine tick over for a few minutes after coming in from the slow down lap on the track to enable the oil system to "sort itself out" (as a further precation to the normal slow down lap)

Interstingly mine uses hardly any oil at all - even after a good track day!
