Lots of blueish smoke, milky exhaust liquid and CEL, wacky Wednesdays
In NJ and its very cold. I have lots of blueish smoke and threw a CEL two days ago. The milky substance I imagine is water and oil and that fouled a O2 sensor hence the CEL. Concerned about turbos they are stock and have 95K on them. Anyone else having this problem?

Where have you found the milky substance? If it looks like hot chocolate and
cream mixed together, that's probably coolant and oil intermixed, as you say.
As for the smoke, the cold temps can certainly cause some issues, particularly on the early model 2.7Ts, like yours. Hopefully what you have is most likely nothing more than a clogged "F Hose" and possibly a clogged breather valve. In either instance, this will clear once the weather warms - but until then, if you see the blue smoke again, you need to release pressure from the engine by loosening the oil filler cap (just a bit - don't loosen it all the way). Once the pressure is released you can pull the oil dipstick out maybe 1/2 inch or so and drive the car like that until the engine oil is warmed up. This will allow warm oil and air to 'unfreeze' the clogged hose/valve.
