smoke possibilities?

I have an odd problem and I no longer think it's the Oil Control rings in the engine.

I am producing smoke. It appears to be dark grayish smoke, and very well could be fuel though it doesn't smell like fuel (smells more like burnt rubber on occasion). It's very transparent until it gets piled up from idling at a traffic light. However there is no smoke during engine braking, acceleration, or regular driving. There appears to not be any smoke trail either while I'm driving too. The only problem is that when I'm stopped and idling I get smoke, the longer I idle the thicker it gets. When I accelerate I notice a slight blue tinge that wasn't there previously. I notice no decrease in fluids besides oil, which is decreasing rather quickly (1 qt per 1000 miles).

My theory for the oil and some of the smoke is that it is from the turbo, whether it's the oil drain or oil feed I do not know. I'm currently talking to Turbonetics about it and they tell me that I do not need an oil restrictor until I am at 80+PSI at WOT. Since I've never been at WOT I don't know if I really need one. But at slight cruise I do see over 60 possible as high as 75, but that is unknown.

On top of that this smoke only appears when I get up to temp. It is rare or never has occurred previously when I have been warming the engine. I have a vac leak and an exhaust leak that I will be hunting down this weekend but would like other suggestions for me to check while I'm in there.
