While at the track yesterday doing a HPDE event (road course), car was emitting white smoke from right side exhaust of my 2006 GTO and went into a spin. Review of camera showed oil pressure dropped to zero and car would not restart. After being towed back to paddock, there was no visual evidence of oil or coolant leakage on top on from the bottom. Pulled the #6 plug and it was wet and smelled like coolant. I will be taking it to the shop for investigation, but was interested in what anybody here might have to say. Car has 56k on original motor with a 112HH supercharger.
