My truck has some white smoke now when cold. It doesn't do it at start up, but if you drive it and get in the gas a bit it it will. There's no air bubbles in overflow bottle so i'm thinking injectors. Any thoughts?
Yeah it only does it in the morning when the humidity is high.. Maybe it's nothing.. But i did call the dealer and they told me that about 3mnths ago GM sent out a letter to void any Diesel warranty's if you do as much as put bigger tires on them.. I find this hard to believe, has anyone else herd of this BS?
