At this point i have to agree with the pan diagnosis. Still don't understand how it seemed so widespread before?
I assume you took the pics from a hoist. This might sound nuts, but if you put 2-3 extra quarts in it and tilt the engine rearward and see if you can locate the spot it's coming from. From what i've seen so far it should be pretty obvious. If it's not i have to wonder about a crankcase pressure issues.

I believe the oil sending unit was leaking some and giving a false reading.

What seems odd to me is the OP has alot of sealant on the oil seal.Its odd that its leaking that much.that area doesn't run in oil so its just run down that is leaking and its just running straight out of the motor.Make sure you get enuff sealant under the rear main along the "ears",not the rear seal tho, and that the rear main is not wedged causing a small gap.
