So today the power was off when I got back from the gym so I parked the car on the drive way sideways and I have a pretty steep driveway. The car sat for several hours until the power came on and when I went to start the car and pull it into the garage billows of white smoke poured out of the right side exhaust the up hill side which would have been the down hill headers and cat. It cleared up after a few minutes and nothing else seemed off. No check engine light, no other unusual noises, engine oil temp good, good oil pressure & plenty of oil. What the heck ?

 

Oil sitting on the cylinder wall used gravity to push itself through the rings and into the combustion chamber. This is common if you park the car as you describe.

 

The dragon awakes!
