I do have oil at the inlet to the turbo (where the u-tube mounts up), however, that is quite normal. This oil is not coming from the wastegate hose (mine is clear and clean), but rather from the actual oil return tube flange. There is oil flow that the turbo bearings actually are supported by. The oil comes into the turbo by a pressurized line from the oil filter, thru the top of the turbo. It flows through and has another line flanged on at the bottom. This is where my problem is. The inlet line is totally tight, the outlet line is leaky, and this is my problem.

It seems to me that you migfht have a lube oil leak that seeps into the turbo and flows out the wastegate hose somehow. I figure this because the oil film at my turbo inlet, which is apparently normal, doesnt cause junk in the wastegate hose, so it must be coming from somewhere else or in higher quantities.
