Can too much oil cause white smoke from exhaust? If white smoke continues to come out of your exhaust while the car is running, there are other issues at fault. 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. One of two conditions is responsible for white smoke blowing out of your exhaust.

First is normal condition (so you don’t have to panic) and the second is a not so normal condition which should be fixed as soon as possible. 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.

White smoke can be a big problem or not, depending on the thickness. The white smoke is the result of normal condensation which builds up inside the exhaust system. 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. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke ( steam ) is no longer seen. 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 the exhaust pipe. Even if your vehicle isn’t flashing any warning lights, the smoke coming from your exhaust is a signal that something might not be working properly.

Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder hea a cracked engine block, or head gasket failure caused by overheating. 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.

A pungent odor accompanies the steam, which is an easy way to detect the problem. Other symptoms are engine overheating and loss of coolant without any visible leak. If the smoke is thin like air vapor, then, you have got no problem. The denser the smoke the bigger the problem, which may be cracked engine block, damaged cylinder hea or blown head gasket. The first think you should check is your air-filter and other intake components like sensors, fuel injectors and the fuel-pressure regulator.

Other reasons could be a clogged fuel return line. 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,.

If the exhaust smoke is black: Black exhaust doesn’t always indicate impending doom. If your car emits a little black smoke at start-up, but it clears up as the engine warms to operating temperature, don’t worry – that’s normal for some cars. If it continues after the car warms up, there’s cause for concern.
