Apperantly the truck has been blowing white smoke for a long time out of the exhaust which is said to be normal in some cases according to the mechanic we've seen last.. However there's a constant lag in the turbo. And also alottt of white smoke has been pouring out of the dipstick, the oil cap when its taken off, air filter, and blowing the ccv hose off. We just replaced the starter if that means anything, when we did replace it, oil was covered on it, including the whole undercab. We pressure washed that and the engine to sorta get an idea of where it was coming from, it was spraying all over the engine. And still is. We saw a 6.0 mechanic tonight who told us. The engine is basically blown and that we would be better off backing it down a boat ramp. Wouldnt the truck not be running if the engine was "blown" weve put alot of money into this truck, hate to have to dump more into it unless its worth it. Im very confused on what the next step would be. We've had the egr removed and deleted, its studded also. Any help would be greatly appericiated as no one in this town seems to know what they are talking about. Im thinking it could be a sensor, or the pistons? I cant seem to find any information on the internet of simliar cases.
