What color the smoke is makes a difference, blue smoke=engine oil, black smoke=excess fuel, white smoke=engine coolant.
White smoke coming from the engine can mean many different things. One such thing is that your car may have a blown head gasket or that oil is burning in the engine.
Blue smoke? The end result of a tired engine. White smoke? Cracked head or bad head gasket.
The exhaust should be colorless. Smoke is created by an imbalance of the oil:fuel mixture. Black smoke is too much fuel (rich). White-blue smoke would be too much oil.
If it is blowing white smoke out of the exhaust tailpipe when the engine is at operating temperature, engine coolant is getting into an engine cylinder from a bad head gasket or some other problem
Probably not. White smoke indicates engine coolant getting into the engine cylinders and burning off. This could be a from a leaking head gasket or a crack in the block.
Water in engine-head gasket most likely.
White smoke is eaither a blown head gasket or you have water in the fuel system. This is not to be confused with flooding an engine and seeing white vapor coming out of the exaust in which that would NOT be smoke, it would be gas vapor's. If your burning oil, the smoke will be blue and smells of burnt oil.
White smoke = Coolant leak, head gasket is the likely culprit. Blue smoke = Engine burning oil. Black smoke = Engine running too rich, wasting fuel.
White smoke usually indicates a water leak into the engine block. Blue or black smoke would indicate an oil leak. possibly pistons!! my 88 Monte Carlo did that
engine coolant getting into an engine cylinder from a bad head gasket , cracked or warped head
Sensors do not make an engine smoke, unless one is causing the engine to run rich.=Black smoke = Overly rich fuel/air mixture.==Blue smoke = Burning oil.==White smoke = Coolant entering the combustion chamber.==The O2 Sensor would be suspect if it is running rich.=
