I can't say this is your problem, but I have a Saturn Vue 2002 AWD v6 with the same exact symptoms that occurred this Sunday at noon. The Vue had been sitting outside in very cold weather for two days and had only been driven 5 miles when we noticed the white smoke from under the hood, stopped, and saw oil everywhere sprayed up into the hood. We had the Vue towed to a local garage. After looking at the Vue and researching online, the mechanic believes it is related to bulletin 04-06-01-009A from GM. This lists the cause as:
During extremely cold weather, moisture at the engine crankshaft balancer may freeze to the crankshaft front oil seal, which may result in the oil seal being torn when the engine is started.
It suggests the replacement of the seal with a new one that apparently does not have the issue.
