Pulled the oil pump to clean timing cover, discovered some scoring on the pump, is it useable or timing for a new timing cover assembly with # 11310-66020?
Thanks

My opinion is yes. More importantly, if your oil pump looks like that, I’d wonder what your main, rod and camshaft bearings look like.

This scaring is from the spark plug tube grommet falling into the timing cover. Big chunks of coiled wire, its what gives the tube grommet its ridged roundness. Haven't checked the any of the bearings, questioning them at this point.
