Lately my truck has been blowing a big cloud of white smoke after I start it. It doesn't always do this and it's usually after it has sat for a few hours. I'm not losing any coolant(first thing I checked), Since I have had the truck it has used about 1Qt of oil between changes and this rate hasn't increased. Could it just be an increased amount of condensation in the exhaust? Or is it something else? Any help you can offer is much appreciated.

 

cold exhaust on cold mornings will create this. As long as it disappears after the engine is warm then I would not worry.

Checking your coolant for a mikly appearance and the oil for a milky appearance as well is a good check.
