It sounds like you've thrown a rod.
What color the smoke is makes a difference, blue smoke=engine oil, black smoke=excess fuel, white smoke=engine coolant.
yes...the lack of air would causes excessive fuel which would cause black smoke.
Black smoke means the engine consumes too much gas - possible problem with fuel injection. Is your check engine light on? It could also be a problem with oxygen sensors.
White smoke = Coolant leak, head gasket is the likely culprit. Blue smoke = Engine burning oil. Black smoke = Engine running too rich, wasting fuel.
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
Black smoke would be unburned fuel: fuel injection problem. White smoke in the morning may be normal condensation. White smoke all the time would be blown head gasket (exhaust would smell sweet like burning coolant) Blue-white smoke would be oil burning...bad valve guides, piston rings, excessive blowby, etc. Black smoke = too much fuel in the mixture or not enough air. Check air filter or possibly a stuck injector. Blue or grey smoke = burning oil and indicates damage inside the engine or possibly a faulty vacuum modulator in a transmission that sucks transmission oil. White smoke = water vapor in the form of condensate. It's normal while the engine and/or the air is cold.
Black smoke indicates excessive fuel possibly the engine is flooding this would also explain the gurgling.
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.
Black smoke-you are burning oil, engine is worn out. White smoke-you probably have a blown head gasket. Good luck with either one, both are expensive to repair. The above answer is only partially correct. Black smoke is not oil burning. Black smoke is an overly rich fuel mixture. Blue smoke is burning oil and white smoke is coolant in the combustion chamber.
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.=
The presence of black smoke from exhaust when engine is first fired.That sign could also be an engine running too rich.
Black smoke= rich condition(too much fuel and not enough air). Blue smoke = burning oil(engine components excessivly worn). White smoke= possible blown head gasket. Check oil to see if coolant is mixing in. Also check coolant level to see if it is loosing it. Have cylinder compression test done to verify head gasket problem. Other possibilities are a cracked cylinder head or engine block.
