I'd say Oil due to the color (no fuel smell),....but its on both Exhaust sides as well as If it is even a turbo,Why does it stop + it must be internal then I guess. I'm sure if I pull the Mid pipes i could tell if oil is in there? may Pull the intake and Charge Tubes tonight to See if theres anything Visable there I guess?
For some reason Im Think PCV Reroute caused it since thats 1 of the main things I did while it was apart.
