I’m desperately reaching out here - I’m at a loss. I just freshened up my 88 302 with new slugs, rings, bearings, gaskets, blah blah and I am experiencing an oil drip from the flywheel cover. I took everything down AGAIN to check if I had improperly installed the seal. Although I did not, I changed it again anyway. There is no groove in the crankshaft surface; checked carefully. Things to mention, the flywheel bolts are sealed, the rear main cap has been sealed prior to installation, the leak is not coming from the valve covers, the rear intake gasket nor the PCV grommet. I have all new gaskets throughout and even opted out for the steel rubber ones just so I wouldn’t get a leak. Before I pull everything down again , could there me something I missed????

Mine did the same thing after a new clutch. I hear its not uncommon for a crank that just wont seal. Next time I hope to use a sleeve.

I used the Teflon one from Felpro. Dry , like it said on directions. About a quarter sized drop every day , and the occasional burning oil smell. I give up for now Im doing 134 change over.

Just want to say “Thanks” to everyone who replied to my post. The issue wasn’t the seal after all... it was the oil pan gasket. It is a one piece gasket so I didn’t think I had to dimple sealer in the 4 corners. It pays to read the instruction sheet an not assume!!! Anyway, I applied 2-3 PSI of air to the crankcase and sprayed the rear of the engine. There it was bubbling away at the oil pan where it meets the saddle. Lowered the pan and dabbed 4 little balls of sealer in the corners, buttoned it up and retested.
