So when I pulled my oil pan off my factory motor and put it onto the forged motor, I only disassembled the upper half from the block (never removed the bottom half). The oil pan was completely clean underneath on the factory motor.

Now I put the same pan on my forged motor and the car has 300 easy break in miles and the whole bottom of the pan is coated in oil. It looks like it's seaping out the bottom oil pan gasket and not the upper gasket.

What gives? I had this problem on my other car as well. Is there anything that can be done to keep the oil pans from getting oily underneath?

Mine leaked where the timing cover met the pan since the builder forgot to put RTV sealant there. It blew all over the pan and made it hard to trace.

I put plenty of RTV on the areas where you're supposed to (front and rear cover) so I don't think that's the issue. It really does seem like it's pushing past the lower gasket somehow.

Maybe you have it on inside out?

Good catch -- sometimes I do that with my underwear too. I'll check it out and see if that also explains my low oil pressure and low oil temperature problems...
