Well, finally pulled the engine apart after the smoke screen behind me while driving spoiled any enjoyment for the car I once had.
The main concern at this point is some moderate scoring/scratches on the piston skirts and the cylinder walls. Nothing really deep except for a couple cylinders showing 1/4" long scratches in the cylinder at the very top (above the compression ring line). The heads look okay with no obvious signs of oil leaking past the guides. There is a LOT of carbon buildup on the pistons and combustion chambers considering I cleaned all of that up less than 7000 miles ago. I will evaluate my carb settings and ignition components as part of this process.
All parts go to Ollie's on Tuesday for evaluation - I'll keep you posted.
