Well here's a picture of the plugs. No evidence of wet oil anywhere when I pulled them. Probably hard to tell in these pictures, but color of deposits is a black to brownish and have a sooty texture to them - running my finger over them it feels like 1000 grit sandpaper, and some of the carbon residue transfers easily to my fingers. What do you guys think? Probably should pull the DP to take a peek at the turbo turbine wheel next.
