Smoke coming from tailpipe

What causes a lot of smoke to come from the exhaust? Why am I getting black smoke out of tail pipe? Why would smoke come from a motorcycle exhaust? Leaking or blown head gasket: The head gasket is located between the engine block and cylinder head. It seals the combustion chambers, as well as the coolant and oil passages.

A leaking or blown head gasket can allow coolant to enter the combustion chamber. This in white smoke coming from the tailpipe ,. The first sign of having contaminated oil is white exhaust smoke coming out of the tailpipe. 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. This is generally less common to leak, but it can happen if the reservoir tank were to get damaged or cracked. The most common reason for white smoke from the exhaust pipe that is condensed in the exhaust pipe. Steam is emitted by condensation in exhaust pipe which is seen at exhaust emission. Fuel needs to be burnt fully as it will only emit COand water, which do not cause black smoke.

In this case, bad seals or piston rings cause oil to leak into combustion chamber which then mixes with fuel and burns. The result is a white or light bluish smoke that comes out from exhaust manifold. The white smoke is the result of normal condensation which builds up inside the exhaust system. White smoke can be a big problem or not, depending on the thickness.

One cause of white smoke from the exhaust might be the engine leaking coolant. If the engine leaks coolant, it will be burned by the heat of the engine and then come out as smoke from the exhaust. A problem with antifreeze might also be causing white smoke to come from the exhaust.

Take the same precautions as with blue smoke , and check for excessive oil consumption. Gray smoke can also be an issue with your automatic transmission fluid getting burned up in the engine. The smoke escaping from your tailpipe is actually steam and will appear more gray than white in color if examined closely.

The water is the result of an accumulation of that same steam as it makes its way through the exhaust system and out of the tailpipe where it condenses from its gas form back into liquid. The good news is, not all white smoke signals problems in your car, as some can be due to normal condensation too. A rule of thumb though is the thicker the white smoke , the greater is your problem. Internal combustion engines burn a mixture of air and gasoline to move the car. The combustion of the mixture of this engine oil and the fuel delivers black smoke.

Engine Deposits Black exhaust smoke can be caused by engine deposits. Engine deposits are another reason causing black smoke from tailpipe. When the engine is new, it will run fluently without any problems. Smoky Tailpipe Issues Blue or gray smoke coming from the exhaust pipe.

Black smoke or very dark smoke coming from the exhaust pipe. A new fuel odor or drop in MPG that seems to be coming from. If this is the cause, then the exhaust smoke may come with a sweet smell.

Why is White Smoke or Steam Coming from Exhaust ? A small amount of water is produced as a normal bi product of the combustion process and until the exhaust system warms up the water evaporates and can be seen as steam. You may commonly see white smoke coming from the exhaust on cooler days upon starting. This is likely due to steam created due to the engine burning off the condensation.
