So I think I have narrowed it down to oil causing my smoke and it's gotten a lot worse. Steady stream of smoke out the exhaust now. I took off the tube to the intake elbow and it felt wet. Seems to be some oil in there but not a lot and it's real clean. No black build up or anything. Checked the oil level to see if it was low, but it was actually too full. Could this be causing my problem? Frustrating and embarrassing. Exhaust tip is very oily as well.
Help!

 

Sounds like you have an injector going. I would stop driving the truck and diagnose which one it is. Actually had the same issue. Never had a code until one day it popped up. Replaced number 3 injector and all is well.
