    It is full on white smoke. I appreciate your feedback, helps me frame my questions for the dealer techs. We will be a 1 car family for awhile it looks like (dealer cant get to it for a week). Will let you know the outcome.

    Sounds like you blew a head gasket with all that white smoke---is the coolant level down, that would tell you?? And I agree with the other guy, get rid of the edge tuner and get a respectable one, COBB, MPT, 5*---a company that will actually hand tune to your truck!!

    But true. I can’t know what is happening to your engine , no one can without the proper equipment. But I do know those canned tunes are garbage. And I’ll add a bit more salt.... so are cai. They do nothing except cause problems. They add zero hp. Get a proper tune like goose tuned or mpt. Put the stick box back on. Run the proper gas for your tune. Unless you have damage now , I’m sure all your problems will go away. FYI I have 35,000 trouble free miles on a mpt tuned R

    White smoke can be either coolant or oil. If a turbo bearing/seal fails, the smoke out of the exhaust will typically be white, as it’s being burned in the exhaust, not the engine. Turbos can be damaged from a lack of lubrication, contamination, or over speeding. Have you checked you oil and coolant levels?

    Since the concern started occurring after you went off road in dusty conditions, start by inspecting your intake system for any obvious leaks. That can include piping that is not fully seated, loose connections, or cracks/damage. If the air filter is an oil type, make sure it’s been properly treated. The intake system needs to be perfectly sealed; if it’s not, you’ll have what’s referred to as “dusting” of the turbos and engine. This occurs when dust is ingested into the intake tract, which then has a sand blasting affect on the turbo impellers. The turbos then feed that contaminated air to the engine, at which point is scores the cylinder walls, causing low compression, misfires, and oil consumption. You can also check the inside of the intake tubing for signs of dust to determine if it’s been compromised.
