| engine wear I do believe thepunisher is right, there's some piston rocking going on there. As far as the bearings, have you had any detonation? Are you using a 6.2 rod? or shorter? It looks to placing quite a load on it. Mike the crank and put rod cap back on the rod and mike the inside of the rod separately. Don't use plastic gage to check at this point.
