White smoke from car engine

What causes a car to emit large amount of white smoke? Why is my car blowing white smoke? What does white smoke from the car exhaust mean? What could make a diesel engine produce white 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. Internal combustion engines burn a mixture of air and gasoline to move the car. Below are the top causes of a car blowing white smoke from the exhaust system. Cracked Cylinder Head.

Whenever your cylinder head is cracked or damage coolant will begin to leak out of it. 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. The oil filler cap in almost all the engines releases a faint whiff of smoke , which is a residue of the burnt fuel inside the engine. Older engines produce more hot spots, which make the car smoking under hood but not overheating. 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.

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. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. This is usually caused by overheating the engine and usually causes the oil to be saturated with water.

This is particularly bad because the oil is not effective at protecting the bearings and can ruin an engine quickly. The black smoke may show there is a return fuel line which is obstructed. 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. All these three problems occur due to overheating of the car.

Typically, what happens is a cracked cylinder head causes the coolant to enter into one or more cylinders, or sometimes even into the combustion chamber. In some cases, the white smoke may be caused due to a deteriorated coolant in the radiator. If the coolant has run out, then it will lead to the engine overheating. Another problem is when your car has a coolant leak. Coolant is entering the cylinder and is being burned along with fuel.

Over time your volume of engine coolant decreases hence the reason the reason you are refilling every few days. Also change the oil as well as you might coolant in the oil as well. Is the smoke identical to the exhaust smoke at the back of the car ? Does it go dark when you pull the choke out just like the exhaust at the back? If so, the headgasket is about to fail. While it looks ok, it has only a few of health left and will fail shortly.

If you replace it the smoke should be gone. If the white smoke is exclusively from the exhaust pipe, a leaking cylinder head gasket would be a suspect. In this case the coolant would end up being heated in the combustion chambers and blown out the exhaust as the engine starts. My coolant seemed really low and he added some and I went on my way. With your engine being a V there is a. Luckily I was able to make it home just fine.

If your engine puffs out an occasional stream of white smoke , it could be steam coming from your coolant overflow tank. Leaking and burning transmission fluid and power steering fluid will also create a cloud of smoke similar to an engine oil leak, but with a slightly more chemical aroma.
