Pete Munroe Pete is the distributor and camshaft gear OK? That's some big chunks in the bottom of the pan. Rods 6,7,8 would be the ones with bearing damage because they are the last to get
oil in this motor. I hoping for distributor gear and camshaft. The other thing is pulling the inspection cover off this
oil pump and check the gear faces and clearance of rotors to body. .006" is within spec for crankshaft end play if this is total in both directions. .010" is about the max. I know of 2 cases where the gears in the
oil pump slip on the shafts when the motor oil was hot. When cooled off they tighten back up and worked like normal. Just a thought. Rick L. Ps crank shaft hardness should be better than the bearings hardness unless they are tri metals.
