Just a little insight of what's going on. Had a small knock between 2200-2500 rpm. pulled each plug wire one at a time. When I pulled the #2 plug, the knock went away. Dropped the oil pan and pickup. #2, 3 and 4 rods had very slight wiggle. #1 didn't have any wiggle. I removed all 4 rod caps and removed the bearings. #2 cap bearing didn't have the little tit on the side to keep in place. All caps, rods and crank looked good. no scratches or scaring. Would I be able to just throw some stock/standard bearings back in the block and call it good, or would I need to machine the crank? There was very VERY little metal in the oil, more like a metallic paint as compared to bits of metal
