wild guess.. based upon 40k heads, P&C
and that it's grey oil smoke, not black gas smoke
confirm valve guide wear is ok and check exhaust valve guide seals. Actually i'd probably just replace the seals and feed the gas and oil a few doses of Sea Foam afterwards before opening up the engine without hard info..
i also feel that a 911 leak down test isn't the most reliable for hard info.
