oil leak?!?!

oil leak?!?!
Good morning people. I own a 72 olds cutlass supreme 350 sbo 4bl. Its my daily driver and last week I noticed a few drops of oil around the oil pan gasket. I went under and tightened the screws around the pan and noticed the gasket spreading. So surley I need to replace. Not my question is how can I tell if the rear main seal is leaking? The leak has began to leak more and im wondering what caused the leak (gasket failed, engine ran hot). Im a novice mechanic and need all the help I can get. Thanks yall

Has the engine ever been rebuilt? If so, who did it?
Not gonna lie, sometimes i see a couple drops of oil around my oil pan.
Rather than looking at the glass half empty, i consider it free rust protection.

Man thats funny ! I usually dont let a lil oil scare me but its been hot as satans underpants down here and the leak is getting worse. Im sure the gasket is falling apart for a quarter turn pushed the gasket apart.. Just wanna find out how to tell if the rear main seal is leaking. I can tell from just looking from underneath , but there is a bead of oil in the area outside the seal..
thanks for the support

Hmmmmmm, i believe the original seal was a rope seal correct? If so did you guys change it to a better one when you rebuilt the engine?
I think best way to locate an oil leak is pressure wash the bottom of the engine, clean it really nice, and see where the leak is coming from. But yeah, you've got 5 quarts of oil in that engine, i dont think a couple drips (unless it gets worse as you say with the screw tightening) would hurt anyone.
Cheers,

Did you try to tighten the oill pan bolts? If the gasket was recently replaced, they could be loose due to the gasket compressing. Mine did just that. Snug them up with a nut driver - a ratchet will easily overtighten the bolts and warp the pan.

I have plans to replace the gasket tomorrow and will use nut driver instead. I'm gonna inspect the pan and check if it is warped..
Thanks
