Title: 50 Frazer Rear main rope type crankshaft seal oil leaks.
Post by: Cwayne on November 28, 2009, 12:10:29 PM

I have a substantial rear main seal leak in an engine that was completely rebuilt only a couple thousand miles ago (8 years ago).  Wonder if anyone could suggest a simple cure that can be done with the pan off and engine and transmission in place?  This rope type seal was carefully replaced at overhaul.  I have removed the pan a couple times and see nothing wrong.  The seal holder cap is tight and the seal looks good.

When inspecting the seal, can you determine if it is leaking on top of or below the crank? you may also need to check that your not being compounded with excessive blowby.  This can be achieved by performing a compression test.   I did have a leak once and l purchased a tube of black rtv and i cleaned the pan with rubbing alcohol and put a thin bead down and around the top of the pan. I had to build up agood bead and let it set for a few hours and i added some pan spacers off a 350 chevy and torqued them to 30 inch pounds and it works sofar. The spacers are rounded L brackets and looked better than a short stack of washers.
