Our 2004 Toyota Sienna emits a cloud of white smoke on a cold start. This is not from cold moisture in the air; it is 75 degrees here in the morning. It is definitely smoke, and only appears when the engine has not been started for several hours, and always white in color. Thanks for all answers!
It may also be worth mentioning the oil is clean and clear, and all fluid levels are good. The van runs good, it does not idle rough and does not have trouble starting up.
If it was a head gasket issue, would it show in the coolant and/or the oil? I've had head gasket issues before and the oil was milky brown from mixing with coolant.
 
Antifreeze leaking into a cyc. is the problem note the antifreeze does not always turn colors because it is leaking into a cyc. and thats why it runs rough at first. Rec a leak down test. Note compression test does note tell you if you got antifreeze leaking in a cyc. Rember you can note compress a liquid.
 
thats a normal thing for a car to smoke when its cold out side, but if its doing it on a hot day you may have a burnt valve
