Do you know where the oil separator is?
juan  2:05:23 PM
I think I do
Master Tech Lee

I am thinking the oil separator has oil in it and when you fixed line leak now is sucking oil from it and causing you to see smoke. This would be the first step into the process of elimination. Also there is a TSB about the separator in thais article is about cold weather problem
I am preparing to send to you

Engine – Engine Oil Separator Freezing Concerns

Oil Separator – Cold Climate Conditions

Certain areas of the US experience extremely cold climate conditions during the winter
months. A small number of vehicles in the above-listed Series have experienced problems
ranging from leaking or broken valve covers to complete engine failure.
Moisture accumulating in the engine oil separator; hose to oil dipstick guide tube; or the
orifice in the dipstick guide tube can freeze. When this occurs, depending on the position
of the internal valve, it may either cause high crankcase pressures (stuck closed) resulting
in valve cover leakage and or breakage, or cause an oil hydro-lock condition (stuck open),
which could result in engine damage.
Replace the crankcase vent valve, crankcase vent hoses, and dipstick guide tube.

1.   Replace the oil separator and hoses (1) with the new insulated style (2).
2.   If the vehicle is already equipped with the new insulated crankcase ventilation valve
and hose, only replace the dipstick guide tube with the part number from the list by model
3.   If the vehicle is not equipped with the new insulated crankcase ventilation valve and
hose, replace those parts with the updated style and replace the dipstick guide tube with
the part number from the list by model below.
