GOOD News, not head gaskets!

Is your coolant level dropping or staying the same, check it several mornings in a row when it is cold to see what it is doing. If necessary use a marker to mark the level the first time.

If it is dropping you are losing coolant somewhere and the white smoke tends to indicate it is going into the cylinders. A coolant leak in the EGR Cooler (IF it is still there) or the Turbo both can put coolant into the engine.
