The pick up oil is changed, is fine, the oil pan adjust all, but the rear is bigger than old oil pan, I think if exist any other oil pan for my engine, part than hold crankshaft bigger, or i forget all, and cut an weld the rear part of old oil pan in the new oil pan, make a perfect oil pan for my engine...
