Just got done rebuilding my WD-45 engine and I can't stop the rear main seal from leaking. I've had the engine out 4 times now, done what the farmers around here say to do-used a rope seal from a 1950-60 Ford 390, made sure the oil pan gaskets were not leaking, the last time was the ford rope seal but that was too big. I softly hammered it thin til it fit in the main bearing cap groove but then it fit so tight the engine would not turn over-tryed cutting some off and it leaked. Really would like hear some of your fixes for this leak.(with the engine running you can see the oil come out where the seal is) Thanks, Charlie H.
