i would like to thank troy for this thread! i have the same combo, 472 hemi, early second gen mopar performance block, eagle crank with grooves. i have had that damn engine out three times for issues, and the rear main being a killer as of late......

after getting no help or support from my engine builder in florida, (i paid A LOT of money for this engine, kind of sad that he took this route with me) i ended up following troy's lead, and going with a rope. i have a little moisture back there, (only have thirty miles on the latest seal), but compared to the water works i had with the other two lip seals, i'll take it.....

i think you might be onto something, saying some people have issues, and others don't, and that maybe it does have something to do with aftermarket parts. both lip seals looked ok, cap measured out ok, (used two different ones) but they just didn't work, no matter how careful they were installed.....

anyway, thanks again troy!
