I’m following this as I have the same situation. I had block and mains checked and honed. Front and center are good and rear measures.001. My machinist said it was within spec. but he likes to see .002 min. He said I could try another rear bearing or “ massage “ the bearing. After reading ole Ron’s post I’m thinking that might be worth trying.
