Had a rear main seal tryed evry thing the fix. In my case had a aluminum tool made that fit the seal and fit in the main bairing put the lower seal cap on then shine a flashlight from the back the seal was to low at the block shimed the up worked grate. will never install a rear seal without testing the fit.
This is exactly the next step! I am machining a "stub" that will sit in the main journal and feature the seal journal to eliminate the crank flange. I want to "see" WTF is going on without the damn crank flange in the way. Thanks again! J.Rob
