White Smoke.

[TruckLiddell]

So, When I wake up and go to work it's a little colder out so I go out early to start my truck and usually let it idle for around 10min before I take off for work. Well I fired up my truck the past couple days and white smoke has been billowing out. Once I start driving after it has warmed up white smoke may come out for a while but once I step on the gas pedal for a bit it will turn to black smoke and stay that way.
Once I work all day and come back to my truck, fire up my truck there is hardly any white smoke more how it should be and then once I start driving it goes back to black.
I am new to diesels and need some help figuring out what's going on and fix it. Heard it could be my erg? Possibly coolant leaking into my cylinders? I smelled the coolant and it seams to smell fine.
Any help would be great, Thanks in advance.


(Tired a search and didn't get much help.)

there is no egr on the 7.3. could be a number of things, but sticking injectors or degraded injector o-rings are most common. it could be burnign coolant, does the white exhaust smell like coolant? worst case scenario your losing compression, cracked piston, dusted motor etc.

Could be as simple as bad glow plugs.
