[QUOTE="static74, post: 15059698, member: 82255"] Some updates. Upon taking the oil pan off I spotted trouble. I had some debris in the oil pickup screen, so I decided to take the pump out for inspection. What I found was some scoring in the pump pocket under the gears, one particularly deep scratch enough to catch your fingernail. [ATTACH=full]1427726[/ATTACH] After finding this I decided to check bearings for any issues. I found containerization and scoring in the bearings, likely from dirty oil galleys from when the motor was assembled. I should add that I didn't build this motor, it was purchased from a builder. These will need replaced. It was decided to inspect bore and piston for wear. I found significant side load on the piston skirt resulting in a lot of wear and some scoring in the cylinder. The cylinder showed no signs of previous honing, so either the marks had worn off or it was never done. [ATTACH=full]1427727[/ATTACH] [ATTACH=full]1427728[/ATTACH] At this point all bets were off and the block is going to the machine shop for a crank polish and honing. I will also be re-ringing the pistons. [ATTACH=full]1427729[/ATTACH] [/QUOTE]
