When the engine on my '59 235 was rebuilt ( about 2000 miles, and 6 years ago ) the oil filter was plummed incorrectly. Can you say dirty oil?
Does anyone have any ideas on how to clean the inside of the engine without disassembly? Could you put something on the rockers that would help clean as it goes down to the pan?
Thanks for your help. With STOVEBOLT'S help I know how to plumb it correctly.
