I recently got an '06 H3... Everything is going great except for the white smoke that comes out the exhaust on start-up. This happens when the truck has been sitting for several hours only. I have been researching, talking to folks, etc etc and I cant seem to pinpoint the problem. So, here I am in a Hummer forum hoping one of you can lend me your wisdom, and have had a similar issue. Here are the culprits I have explored and heard about thus far.....any thoughts would be GREAT:
-head gasket(I don't think that's it. After start up everything runs just fine)
any ideas? please be specific, I am new to Hummer Thank you!!
