I have a Ford F250 that I recently dropped a 460 into from a 1978 Lincoln Continental. The car sat for 14 years not started, I cranked it (with fresh gas from a can) after I got it home, it ran fine so I just did a “poor mans bottom end” on it, I have about 6000 miles on it now and it smokes pretty bad on the deceleration from the passenger side pipe, is this a sign of a broken oil control ring ? I am sure I should have put rings in it while I had it on the stand in the shed when I put a new cam, lifters, valve stem seals, springs, retainers and locks, oil pump, timing set, rod & main bearings. The car had 93K miles on it when I pulled the engine and did not smoke when I started it, and it ran so smooth I thought the compression and rings all were fine… it has come back to bite me in the … well the back side, do you think I should pull the engine and bore it .030 with new pistons and rings, or do an in-frame hone and just new rings.
