I have problem with a motor that I got that had sat for 7 year's . I got it running after replacing the carb & point's . But as it warms up it drips more and more oil out from were the crank pully enters the case . Could it just be I need to replace the pully ? Thinking maybe the oil slinging groove's are filled with rust and not doing there job ?
There must be a seal in there that is leaking. I had a leak from my rear main seal and added an additive to my oil that is supposed to swell the seals slightly, sealing the leak. That was about a week ago and I haven't driven it since. I'll keep you posted on if that stuff worked.
the sand seal kit comes with instructions. when you install the seal the engine needs to be clean and use a 2 part epoxy(like squeeze tube jb weld) or what i used, indian head avation sealant . all you have to do i remove the crank pully , clean the engine of oil and grime where the pully slides inside the motor , put the sealant on the seal and install it into the engine, let it sit 24 hours so the sealant can dry . install the supplied washer then the crank pullyand then the bolt and washer then torque. there is also a smaller washer that goes installed behind tour alternator pulley.
WAYNE: Did your oil-additive stop-leak do the trick? I believe I've got a front seal that's headed south, but I need to put off the fix for a while. I've been contemplating an oil additive, too. Please let us know if yours did the trick. Thanks.
I hate to say it but it made the problem worse. Where I would have a couple of drops on the floor I now have a little puddle. I ordered a special silicone double lip seal and I'm going to have to put in about a week from now.
