Oil leak on Back side of engine

1997 OBS 7.3L.

I have a oil leak down the back side of my engine. I checked for oil on the front side of my engine and didn't see any. It all runs down the back and blows all over the oil reservoir and the qorque converter cover plate. If it is coming from the back of the engine, does that narrow it down to the EBPV or is there other stuff back there?

There is a drain in that area of the valley I would do my best to clean all the oil up and look for a source

more than likely its from the exhaust back pressure valve.. its a very common leak. search youtube and there will be some videos showing you how to repair it, or you can just ignore it since its a pain to do and it wont hurt anything if you decide to leave it. there are other possible leaks, but this one is widely known as the "most common" leak at the rear of the valley.
