well the #3 big end rod bearing is shot, it sure makes a rattle sound when it first starts up. Then in goes into a tick/knock sound. Anyway, I've got everything apart and the bearing is so far gone I can't see any color on the bearing like the manual says. I was thinking of ordering all 3 sizes and plastigaging till I got the right one. Anyone have any tips on getting this right. The manual says measure the ID of the big end but without a color on the bearing I'm kinda in the dark. Any help is greatly appreciated.
