I think somebody overgapped your rings, or just stuck 80mm rings in there, that'll pump oil. Piston/bore clearance of 0.0055" is too much, even for forged pistons, they'll flutter and pump oil. Also, rings like round holes. You report 0.0008" out-of-round in the cylinder. Rings can't seal to that kind of oval, they'll pump oil. Lastly, max wristpin clearance is about 0.0015", you report 0.003", way too (rattly) much. That won't last very long...
All of those are hard facts. So, maybe I should consider new connecting rods, and either re-sleeve, or bump up to the next size piston...
