Trying to figure out if I have two oil leaks or an oil and transmission leak on my 73 Duster 318

First thought is that it has a rear main seal leak.
So far no indication of the trans leaking.
Of course it’s possible the leak is actually higher up, like a manifold leak, or valve cover, or even an oil sender.

Get ready to have people telling you to tear everything apart and rebuild it.:D

Clean it up and verify first,
but that sure looks like classic rear main leak.

Thanks for the input! Very true about it being higher up. Let me fix the drain plug first and clean down the engine. The rear main seal seems like it could be it and I’d rather it be that than a trans leak. I won’t be tearing the whole car apart haha I mean if it doesn’t leak a little bit of oil is it a mopar? It’s free rust prevention.

I’ve had decent luck with AT-205 reseal as engine oil additive too so maybe I’ll try that first.
