Have a SBC 327 with an extra deep, baffled, aluminum crankcase
cover which has an (UGH) oil leak. To set the scenario-- I have replaced lower gasket set/ front and rear seals twice. First time I had a leak at the rear split seal, minor as it was ( 1-2 drops per 3 day time period) this was not acceptable to this anal geezer.
My 2nd time replacing gaskets and seals, again a minor leak
appeared, this time on the front seal. Same procedure was used with both attempts to resolve this dilemma Have had no leaks in the mating surfaces of the pan gaskets (cork) just the seal areas.
About to forge ahead with 3rd attempt and wish to avoid another
great accomplishment!
Now my question - Is there any latest and greatest sealant to apply on the tab ends of the seal after they are inserted and trimmed off?

Any hints, advice or direction pointing this geezer to a solution would be welcomed and appreciated. Thanks for your time.
