Reply to "Leaking rear main seal - sometimes!"

4vandproudMember

as it turns out aftermarket cranks (stroker cranks) usually don't have the oil slinger that the factory cranks have. lots of guys battling rear main leaks curse the standard neoprene flavor of the day rubber seal that never has an issue with a stock crank, only to find that the now discontinued can't get them any more Super Duper fluoroelastomer seal doesn't do any better than the regular seal. then they try to blame it on the diameter of the sealing area of the crank, nope, the diameter's correct. try another Super Seal, still leaks ...

my $.02 is that there's no integral slinger on the crank & if there was it wouldn't be leaking. here's a pic of a damaged rear oil slinger on a stock crank, pretty sure stock Windsor cranks have the same?
