How is your crankcase ventilation? If you have pressure build up in there, you will force oil out of the turbo. A valve cover breather fixed my similar troubles (after I already rebuilt turbos, put in small feed lines, reclocked-all of which did not work!!!)

sounds like the seals to me. I doubt the return line would be backed up. It looks big enough and there are no kinks.

get proper oil return lines?

Try one of those razu stealthmode oil restrictors, also you need to get a dumptube on that thing ASAP! ---- at WOT your exhaust is dumping right into your compressor inlet, thats going to make the car run like ---- at wot.

Also, the oil return it is on TOP of the pan correct? the pic looks like it.. just wanted to make sure.

I'm assuming thats a Turbonetics turbo? which model?
