Thick smoke coming from exhaust

In this situation, we suggest to not ignore it. Thick white smoke pouring from the exhaust is usually due to a crack in the cylinder head , engine block or head gasket. This is caused by constant temperature fluctuations and a consistently overheating engine due to low coolant levels.

The result is a white or light bluish smoke that comes out from exhaust manifold. If you see white smoke coming out of the car exhaust pipe in thin wisps , but only when you start the engine and not while driving, there should be no need to worry. This is due to an accumulation of condensation that finds its way out through the exhaust pipe. The most common reason for white smoke from the exhaust pipe that is condensed in the exhaust pipe.

White smoke that is like vapor and disappears soon could majorly be because of condensation. Steam is emitted by condensation in exhaust pipe which is seen at exhaust emission. As this continues, the white smoke will begin to have a sweet odor smell that won’t go away. Damaged Coolant Reservoir Tank Another area that can leak coolant is the coolant reservoir tank. The symptoms below are the most commonly found smoky tailpipe conditions.

Blue or gray smoke coming from the exhaust pipe. White smoke or water vapor coming from the tailpipe, especially in the morning when the engine is cold. Black smoke or very dark smoke coming from the exhaust pipe. The first think you should check is your air-filter and other intake components like sensors, fuel injectors and the fuel-pressure. If you notice that your car is blowing white smoke.

Thick , black smoke suggests that the engine is being flooded with gasoline. The black smoke may show there is a return fuel line which is obstructed. Fuel injectors and sensors might also be damaged.

So, if there are thick and black colored vapours, this means that the fuel burns with the less amount of air in the engine. Now the question is what causes the formation of black smoke out of exhaust? Well, the answer to this lies with the faulty car’s component like air filter and the fuel injectors.

This is probably the result of normal condensation buildup inside the exhaust system. This kind of smoke disappears quickly. However, thicker smoke is a big problem, and can be caused the engine burning coolant. This can cause severe damage to the engine if left unchecke but you may first notice bluish smoke coming from your tailpipe as some of the excess is burned.

You can check your oil level by driving the car for five or minutes and then checking the oil dipstick. How To Fix Blue Smoke From Exhaust. As blue smoke coming out of exhaust can be caused by some of the reasons mentioned above, so to get rid of blue smoke , you should find the cause and fix it immediately. If the exhaust smoke is blue or gray: Thick blue or gray smoke is an indication of the vehicle burning oil, which means that oil is somehow leaking into your engine’s combustion chamber. Burning oil like this can cause a wide range of issues from reduced fuel economy to less-than-stellar acceleration.

Condensation that accumulates inside the exhaust pipes, converter and mufflers can produce a puff of white smoke upon diesel engine start-up. In very cold temperatures, the heated exhaust can freeze into minute fuel droplets when exiting the exhaust and produce a more prolonged emission of white smoke for a very short period of driving time.
