I am fairly sure that the car has developed the ol cam seal leak. But I wanted to ask around to see if there are other ideas or the best way to diagnose it.
Noticed a new oil drip on the driveway under the car recently. Right side, in the middle of the wheel-well, and outside of the skid plate. Looked under and saw some drips on the plastic shield over the axle, coming from above. Checked the banjo for the turbo oil feed and it was all dry. I can seem some oil on the timing cover on the exhaust side.
I pulled the plastic covers over the cam gears, intake looks fine, the back of the exhaust cam looks like it might have been a little damp, very slightly. More shiny than anything. But looking down inside the cover I don't notice anything obvious below the cam gears for leaking.
I did just replace the diaphragm for the PCV, had the tear and the howl. Car wasn't driven on torn PCV for very long as far as I know. I parked it once the diagnosis was confirmed torn PCV diaphragm. But maybe it was possible that it was long enough to hurt the cam seals?
