7.3 idi 90k miles, starting idling really rough till about 1200 rpms with white smoke. rough idle clears up at higher rpms. smoke smells like fuel and no blow by from the oil cap, as well as the upper radiator hose isn't hard. egts went up about 100 degrees afterwards for the rest of my trip on the highway. don't think its using coolant (leak). what else should I look for? timing is advanced.

EDIT: I pop tested 3 injectors, they failed pop pressure and spray patterns.... oil dipstick has little bubbles when pulled, and oil feels thinner than it should. more of a brown/black color. gunna change injectors and go from there. truck has a e fuel pump, I deleted the mechanical pump.

 

Timing and injectors. That's basically what is amounts to.
