Bore scoring happened on M96 engine(97-08). 9A1 blocks switched to Alusil. 9A1 bore scoring is practically non existent. A handful cases, but not anywhere near M96. M96 also had oil starvation issues, that too was solved on 9A1 with baffling and variable oil pump. N55 and S55 in M2 are definitely not without their own faults.
