Hey sorry to hear about your problem. What you are seeing an oil leak on your turbo crossover pipe, I noticed this also on my truck about a month ago. 1 dealer tried telling me it was normal, well I like you looked at my buddies truck and sure enough super clean and no oil. So i got a second opinion from a different dealership service tech..... here is what they found and fixed under warranty: They ran an All in 1 DYE test and they found seals at the turbo crossover pipe and at the extension pipe at the turbo both leaking, they removed the degas bottle, and cross over pipe, then replaced gaskets that mount inside of crossover pipe, also had to replace the gasket that mounts into turbo. Hope this helps.
