2003 Boxster S, Oil Castrol Edge 10w 40

After my 20 minute DE sessions I perform a very easy cool down lap. When I restart the car an hour later a good amount of orderless smoke comes out for 3 seconds.

I replaced the AOS with a new unit and have the exact same problem. The car runs fine around town and on the highway and only blows smoke after a track session.

The car is on street tires, the track is NHMS (vicious left hand banked corner), and I run in the blue group. Other Boxsters and Caymans at the track do not smoke at all.

Help.

Also sometimes coming out of the sharp banked left hand, the check engine light flashes. A OBD reader shows misfire in cylinder 5. This happened at the exact same point on the track 3 times in a row.
