Okay this truck has always smoked pretty good on start up, 03 7.3 350000 kms, it's got all new glow plugs in it, tuner, new injectors, tested glow plug relay and seems to work, it's really not that cold out and puffs smoke for a good while. Motor just warn out or is there something else I should look at? Doesn't seem to have performance issues since I changed injectors. When I take off fill cap and run it, there seems to be little too no blow by, next to no play in turbo shaft as well. Ideas before winter hits lol?
