I have already made sure the bearing's are fully seated. I took some additional measurements and the end of the pin on the crankshaft is about .0002 from the back plate. So I think that means that the rod is not sitting on the the crank pin fully. I all so measured the diameter of the big end of the wore out rods and they are all oblong by a couple of 1000's. Maybe a shim on the small end of the rod is the answer.
