Why does my 7.3 white smoke?
If your 7.3 Powerstroke produces white smoke on startup, but then the vapor dissipates when the truck gets warmed up, the white smoke is likely from unburned fuel. When your combustion temperatures aren’t high enough to completely burn off fuel, your engine becomes filled with stiction.
Does white smoke mean blown turbo?
Hi! A leaking turbo will usually present itself through white smoke exiting the exhaust. Usually the white smoke will result from the turbo leaking oil internally but will occasionally result from internal coolant leakage.

Black Smoke consists of fine particulate matter. These particles can be hazardous to health especially in combination with other pollutants which can adhere to the particulate surfaces. Black Smoke is emitted mainly from fuel combustion.
If your exhaust pipe is emitting black smoke, it’s likely because the fuel/air mixture is too rich. In order to combust properly, your engine needs a precise mixture of fuel and air. The mixture is “rich” when it has too much fuel or too little air.
What color smoke is rich fuel?
