Those are the bearings and I can't see anything done differently in my engine but the front and middle bearings don't last either. A piece breaks out of them from the end of the oil slot to the edge of the bearing on the bottom insert. That hasn't been fatal but I got to the rear one just in time to avoid a more expensive exercise.I'm being serious when I ask "Is it possible to go back to babbit bearings now that the block has been machined for inserts?" I would be happy enough to stick with the bronze thrust faces but these inserts haven't been what I had hoped.
It is no burden to carry a little extra knowledge.
