  1. XTS-V 2014 - head gasket?

    Cadillac XTS Forum 2013-2019
    First post here, hopefully I'll follow up with good news. My 14 V has little puffs of white smoke that smell like coolant when I start it from cold. It's at the dealership and their "Heavy Tech" says he's working with GM to identify the source. Is there anything it can be besides a head gasket...
