The new crank has grooves where rear main seal sits. Installed new billet aluminum cap. The new split rubber seal leaked around crank (not side seals) when I assembled and ran oil pump with drill. Dropped pan and disassembled cap and cleaned but did not find anything unusual (diameter same as original crank). Installed new Viton split seal and side seals---still leaks around crank. Anyone know where I can find the old type Rope Seals? Thanks (Pretty frustrated now).

OK does the sealant go under the rope/just on the tips or live every 24 hour block of time like it's your last day on earth

They did every improvement they could think of before the Feds made them start putting all their engineering into emissions. So, what exactly did the factory do in, say..., 1972? What was the exact assembly line procedure? You could neglect them forever and a day and they still wheezed on.

The 440 source rear main seal cap needs to have .010 taken off of the height (where it sits on the block) to get the correct amount of crush on the seal. This is per 440 source. I don't know what brand you used but just a thought.... Good luck 1937 Plymouth R/S Coupe 440/727

Just measured mine (from area where bolt sits is 2.980" (+-.001)) Does this measurement sound right?

I met a guy at a car show this spring that had the rear main leak, he found out about having to mill off the .010 to stop the leak. I just purchased a rear main seal cap from 440 source two weeks ago, i asked them about cutting the .010 off, they said it should be done. Why they don't make them the correct size??????????? 1937 Plymouth R/S Coupe 440/727
