bdave_mcc,

To me, it looks as if your photo your Rear Main Babbitt is cracked.

Look at the right side, front side of cap, at the radius where it is flush with the block, both sides appear separated. It looks as if it runs from one side to the other, not parallel but at a arc, looks like pitting at the bottom.
