White smoke (lots) from exhaust?

[coachb]

Had a huge amount of smoke from the exhaust appear during a skidpad exercise. Had done 3 ten lap trials of the clockwise pad, when I did my first lap of the counterclockwise pad there was a lot of smoke from the exhaust. I shut her down. When started 15 minutes later some smoke came out and there was a strange ticking engine sound, shut it down immediately and had it flatbedded to mechanic who looked it over and found no problem. He thought it might have been some oil in the manifold that occured because of an oil vapor separator problem the previous owner had. Does this sound possible or probable? Needless to say this is not how I expected my first DE event to go. Really enjoyed the throttle steer on the skidpad while it lasted.
