Piston and pin great, rings not as good
The piston amd pin were excellent and within specs. However, the rings have a little to be desired. First the oil ring is the old single piece instead of the newer 3 piece. While it is oem style it is old technology. Second the rings are not that tight. The service manual calls for ring end gap to be between .010-.023. The best I could get is .017. While this is within spec it's towards the end of spec meaning it will act similar to worn rings. I wish these were in the tighter side so the rings would have more life. The cylinder was at oem spec so it's not an issue of worn out cylinders. If it wasn't for the rings being larger gap than I think new ones should be I would give it 5 stars. Great quality just not how I would expect rings to be new.
