Dealer isolated to oil leaking into intake system and leaking past tuning pipe seal on to the top of the engin. Performed smoke test. Performed Diagnosis for oil leak. Found air/oil seperator to be faulty. Removed and replaced air oil seperator, Crankcase ventalation pipe, and tuning pipe gaskets. I believe it to be valve cover gasket, watching for additional leak signs.
