As for the scavenging pump, I was unable to set it up so it could pump the discharged oil from the turbo. Rather I let the discharged oil drain into one container, while I placed the scavenge line in a different one with fresh oil. It sucked that new oil up pretty quickly, which lead me to believe it was functioning as it should. Its only took a few seconds of scavenging for me to realise this (thats how good the rate of suction looked). I really should set it up to scavenge its own discharge though.

There will be somewhat of a film, but it should not be wet to the touch. If I understand you correctly, you do not have the scavenge pump connected to the outlet of the turbocharger yet. This may be the problem. The scavenge pump will always scavenge more oil than the turbocharger outputs. Could you be putting more oil back in the oil tank from the "fresh oil" container than is exiting from the turbocharger outlet? This would result in the oil in the tank overfilling and entering into the breather tract of the intake.
Also, I supplied a couple of pics from another thread which illustrates how much oil should not and should be exiting the outlet of the turbocharger. Not very scientific, but you get the idea.
