THANKS, Rif, this is a good start to confirm exactly what you had done so far. Too many times, the answer is hidden in an unanswered question.
Good point about the liberal oiling and the breaking of the glaze.
In the old days, I typically saw 50ish ft lbs to rotate the entire setup including pistons, all torqued to specs. Some would be a little tighter but I never saw a motor hit 100 ft lbs unless I had a main bearing/crank straightness problem. I suppose a too-tight rod bearing could contribute to the problem but it sounds as if the piston/rings/bore is the culprit. Lots of oil on the rings/piston skirts. We used to use the freebie STP for this but it attracted too much lint from the shop towels so we stopped.
