If white smoke is coming out of the exhaust when the engine is warmed up , it sounds like engine coolant is getting into an engine cylinder
White smoke is a good indication you have a blown head gasket. And/or a cracked head. Did you noticed, when it happened that the engine started running rough? Best i can do with little info.
i have a 3406b inframed new head injectors runs rough and pours white smoke had pump and timeing advance off timeing advance rebuilt put back on. now its worse
If an engine is running rich, it is receiving and burning too much fuel and that will yield black smoke. If an engine is somehow burning oil, that will yield white smoke.
Moisture in the exhaust, or a cold running engine.
check the oil in engine to see if it has coolant in itwhite smoke is caused by coolant or water burning with fuelsounds like you have a blown head gasketi would also find a better mechanic
its probably burning oil, if the smoke is white. if the smoke is black, it means its running rich. if the smoke is white, you have serious internal engine problems
You may have a blown head gasket, or less likely a cracked engine block. In either case, some symptoms are a loss of power/ rough running engine and white exhaust smoke.
White smoke is antifreeze, intake or headgasket.
There are three types of smoke that will exhust from your gasoline engine: White smoke, actually is steam from condensation of water within the muffler and exhust system. Number two is Black smoke, this is from unburned fuel. The engine is running far richer that it needs to be. Number three is blue smoke. This is usually associated with oil comsumption.
White smoke = Coolant leak, head gasket is the likely culprit. Blue smoke = Engine burning oil. Black smoke = Engine running too rich, wasting fuel.
If White smoke with oil come out from DDC running Engine Breather out let, it symptoms of Piston Ring set wear out and injector has to be calibrated,
