My assumption was correct. This motor had not been rebuilt, nor ever been apart. Well worn 90mm P&C's, rings were shot.

The good news, and deciding factor for this motor was the crankshaft. The journals all measured in spec. No deep grooves or gouges. The case looks great; only oil stains on the bearing journals. So with that info I decided to re-use the crank and rods. Had they been out of spec, I was going to replace all internal with a 2.0 drivetrain.

The camshaft is pretty worn, but I never intended to re-use it anyway.

More to follow after I order all the parts, rebuild the 1.8 heads I have, and return from the machine shop.
