Maybe a long shot but did installer forget to put anaerobic sealer between rear main and block?

lol, thats a good question, he told me everything was done correctly, but then again he did a smoke test and no issues except for a slight leak at the front of the pan...............wouldnt surprise me if he didnt even fill the anti-rotation holes.

Im trying a few suggestions i got from my two posts about this, then figure out what my next move is.

In all my years and 5 engines in my 73 TA, it has always had oil leaks. Even using the latest greatist rear main seals, pan gaskets, valve cover gaskets etc. and permatex goup. Always had a fog of oil on the car chassis and small drip. Did some research on my breather PVC system and bought a Wagner dual adjustable PVC valve. Seems to have cured the problem. Poor mans evac system!

Great advice here. I've used anaerobic for years on rear mains in my Buick builds. I also use it between the 2 halves of the neoprene rear main seal that I use instead of the rope seal. I haven't had a rear main leak since I started doing it that way. Far superior to silicone.
