    Default Blue Smoke at start now while driving.... Not Happy......

    Well it started about 2 weeks ago At start up in the morning a large blue smoke from the tail pipe.. Did not think much about it Put some Seafoam in this week thinking it might clean it up.. Last night while driving to a friends house at about 70 MPH I looked back and saw a Large Blue smoke cloud behind me I think it went between 4-8 on the motor.. Not happy.... I checked the oil and was low by 1-2 Qt's I put 1 in for now. (Oil change about 2000 miles away) I know there is a TSB on this and as soon as I get back from my trip the Ol dealership will be getting a call..

    It does not matter what it has. It is under warranty, so the dealer can figure out what it wrong with it.
