Wow.

Look on the bright side, least you found it prior to the motor knocking.

Meh, just remove the knock sensor then

This isn't the kind of knock you can ignore. Well, you can, just not for very long

ok boys, I'm ready for assembly, I checked everything over with a mic and dial bore gauge and verified my measurements with plastigage. I'm looking at 0.003 for oil clearances on the mains and rods. I would of liked 0.002 but with such high oil pressure due to the lack oil balance shafts I think this is beneficial. The person who assembled this motor did it totally half assed. The old crank was way worse than he said..... 1,2,3 rod journals were all 1.76--number 4 was 1.74 this motor wouldn't of had oil pressure. The mains were off measuring 2.23---. The motor would hAve been destroyed. I'm glad this happened..... now I can build my own damn motors, from top to bottom.
