Should of mentioned this above, apologies. Engine core was a good one with 60k miles. New OEM Main's were installed when the rebuild happened 14k miles ago.
I am going to be talking with the engine builder about machining extra clearance the top bearing in Main Cap 1. This is recommended by a good engine builder in England. See video above from Dr. Ferry!
Thanks for the feedback!
