Hello this is my first time on this forum ive been helped a lot by just looking and reading all the issues people post..now i have an issue. Dont believe i seen this on here but bare with me and thanks in advance for taking a look.

I have a 2011 f250 6.7 that lasted 230000 miles before i bent the crank (this is what the mechanic said at least) so he found a 2015 6.7 with the turbo that had roughly 67000 miles on it. My truck is deleted and 4" exhaust from downpipe. Spartan tune i always run on hot as it such a pain to set it back. I havent pulled a trailer or my boat with this this new motor (new to me) in it. Its been installed since 6 months ago. Yes i do get on it every once in awhile. So my issue is its blowing white smoke terribly (embarrassing lol). I own a hvac co. In kansas city and im constantly driving all day long from house to house. I took it up to a different shop who a friend refered me. So before i went there the only time i would c white smoke is if i filled up the degas bottle drove the truck shut it off. Once i started it back up if clouded the street and then would go away. Before he put 15lbs of pressure on the bottle he could get it to smoke if he put it in any gear but once it was back in park it went away...im boggled until he pressurized it now the people driving behind me cant even c the smoke is so bad. I figured if there was a crack he opened it more. Obviously i dont blame his as i have a problem please help if you have an idea
