Changed oil 3 times and oil was black from the coating and the filter had coating material in it. Leakage ranged from 9-55%. Going to tear it down in the next couple days to see the reason but I'm sure the rings are damaged or gummed up from the coating.

Bob,
Did you tear it down and what did you find?
