Hi there! Here is a good way of testing your turbo scavenge pump:
930 Oil Drip Tank Fills When Engine Is Off -->Causes smoking
Just curious, what turbo are you running? Is it an original 3LDZ, a K27, a K27 variant, a Garrett of some sort, etc. Also, there aren't many parts to the scavenge pump. Other than a couple of o-ring/seals and paper gaskets, it's a very basic drive system off the cam.

EDIT: I forgot to mention that the link I posted above assumes you have aftermarket headers, which usually require a different drip tank. If you are running a factory drip tank, this might be a little more difficult to test, but I'm sure someting could be cobbled togther. Also, on the factory drip tank, I think there is a vent that runs up to the factory air box, is this connected?
