Oily Turbo???

yep u read it right. i was under my car looking at my floor and measuring up some pieces. and i glanced at my turbo. whole bottom of the outside of the compressor housing all full of oil as well as the Oil Lines. (the lines on the bottom) all soaked with oil. i have a bad Valve cover gasket and possibly but i dont think Head gasket also. how could this oil get there??????
