41 Plymouth Hot Rod Build

Darn. I'm still fighting this oil leak and am going to take a day off and go to an auction with friends. I called Kevco yesterday to talk to them about one of their pans and the tech support guy, Josh, gave me a great idea. He said to block off the breather or PCV and take a shop vac and, in blow mode, pressurize the crankcase while squirting soapy water around the leaking area so I can see exactly where the leak is coming from. Then, clean that area as best I can with carb cleaner or similar.

Next put the vacuum in vacuum mode and de-pressurize the crankcase while applying RTV to the area. This will suck the RTV into the leaking area of the seal. Let it set up and give it a try. I'm almost certain it's leaking on the rounded portion of the cover but this will help me find out for certain. I will let you know how this works out. Not sure it's a long term fix but just knowing where the leak is is a big help.
