NEGITIVE CAPTION! WE HAVE A PROBLUM! :'( Oil coming out of anything other than the oil inlet and outlet on the turbo is bad!!!! But dont freek just look for your local turbo guys and have them replace/refreash the cartreg, or the center part of the turbo. Or if your confident and machanicly inclined you could do it your self, its not to hard. your looking at $50 to $250 depending if you do it your self or leting some one elce do it....

its pretty normal to see "black stuff" carbon on the wastegates, little flakes or whatever, but if you have an actual fluid, like oil in their, you may have a problem with that turbo. The exhaust turbine seal maybe puking oil out the exhaust.

no its not coming out of th eturbo itself, its coming out of the wastegate cylinder, the thing that attaches to the turbo and opens the wastegate, every time i pull the wastegate open and then let it go it does its job of coming back and shutting the wastegate, but oil or grease comes out of the actual cylinder in to whitch the shaft goes to. if i had pics i'd make this easier, but you should get what i'm talking about.

That typically means that the diaphragm is shot on the actuator. A leak in the diaphragm will allow moisture and other fluids to get into the actuator and when they sit in there, they turn nasty. All you need is a new actuator and you're good to go.
