I have a friend with a 06 Ford which smokes every time when he starts it. Here in AZ mine never smokes when I start it but I keep it in a garage. Last weekend I was out camping in 18 degree weather and when I started it showed no smoke so I am not sure whether or not smoke is normal for DMax. I have 51K on my 03...My $.02..Jimclancutters;1556891; said:I'd just write it off as it bieng a diesel. They will do these things, and without an explanation. We have an 05 Excursion (6.0L, No problems), and that will smoke (white) worse than my DMAX in cold weather. A cloud of this whiteish-blueish smoke I would have to assume is normal seeing as how both of our diesels do it in cold weather and even continues out on the road for a short while on occasion.
