Not yet, but one wouls think these items would also smoke on the street under hard accel or braking, no?

Forgot to ask, was any work done on the motor before this started happening? Or did it just start on its own?

Not mine. Only under certain conditions and very hard track driving. When it first appeared (the big cloud of oil smoke out the tailpipe) it was at the 3-4 upshift after a long sweeping corner (Sonoma turn 6 exit). Then after a gentle corner. Then again on the long corner. I parked it at that point. Broken ring lands, bad compression test / leakdown test result.
