Sounds to me like you need to restrict the oil flow to the turbo. Too much oil in the turbo and it will leak past the end seals. Normally the turbo is fine. Do you have a return pump and is it working if you do? This can be another source of trouble if the oil is building up in the return line to the engine. Cold weather and thicker oil make this problem worse and will bring any shortcomings in your oiling system to light. Hopefully the fix will be relatively easy and inexpensive.

It can be a number of different things. I've been chasing a random oil smoke problem for awhile too.
Assuming it's your turbo, it can be due to bad seals, insufficient oil drain size, oil backup in the drain, too much pressure from the feed line, or insufficient crankcase ventilation.

Take a look at your drain hose, and make sure it is not kinked or anything. The line from front valve cover where did you run it? Got any picks.
Another thing is once oil gets into the system, it will take a while to burn out.

Im running mobil1 5W30 synthetic. It is cold out and my hose has a slight kink but not bad. Im running 5/8 hose to the oil pan. I will try to get some picts later. Im thinking about trying 0/30, and re routing the hose. I don't think it is the turbo, because it only has less than 500 miles on it.
