I drive 60 miles one way to work. On the trip home and getting into stop and go traffic, I have smoke coming out of my truck and a strong burnt oil smell. I think the smoke is coming from the tail pipe, can't really pinpoint it. I usually notice it when stopped at a traffic light, or when I park and let it cool down at home. It doesn't do it every time and I've never noticed it when arriving at work of the morning, still letting it run a bit to cool the turbo. Is there any way the turbo could let oil past a seal at low to no boost pressure and contain the oil going down the highway at 7 to 12 pounds boost? I don't seem to be loosing engine oil. I usually change at 5-6000 miles and never have to add before the change. I would like to hang on to this truck for a while. It has 158000 miles on it and I've owned it since new.
