I don't know if this is normal or if the Turbo has a small leak, but when I changed mounts last week I had to disconnect the intake line that runs from the rigid section (aft R/H behind the radiator) to the turbo so I could get the R/H engine mount out. When I did this I had a fairly large puddle of oil that dripped out of the line. I checked the diverter valve since that was right in the area where I disconnected the line and it opened normally when I applied vaccuum to it. Other than that I'm not sure if some turbo blow by is normal or not.

I would appreciate partaking any knowledge from someone who posses it regarding this matter!

Thanks,

Normal to have oil in there. If you are burning oil, then the turbo seals may be shot.

There's no way to avoid oil in the intake. First, it's effectively impossible to seal the turbo's oil jacket perfectly, and second, the 1.8t has a secondary crankcase ventilator that sucks oil fumes from the engine into the intake instead of into the manifold. (this is because the manifold doesn't always have a vacuum in it, but the intake does.)

This is how they keep the DV properly lubricated. j/k
PCV drips/mists this into the intake.
