I have this same issue but with the 3 liter diesel. I had about 35000 miles on it when I first bought it used and noticed dirty oil on the turbo discharge. I took it to a GM dealer to have it looked at and they told me it was normal due to crank case fumes being fed back into the turbo. I don't think that a truck with this few of miles should have this much oil discharge leaking out of the turbo outlet, just my opinion. Otherwise the truck runs well with no CEL's currently.
