White smoke out of engine

What causes white smoke from a diesel engine? Why does engine blow white smoke? What is the cause of white smoke from the tailpipe? What does it mean when a diesel engine is blowing white smoke? The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air.

Internal combustion engines burn a mixture of air and gasoline to move the car. Then after about seconds to a minute, the white smoke should clear up. If this is the case then you have nothing to worry about.

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 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.

The black smoke may show there is a return fuel line which is obstructed. Fuel injectors and sensors might also be damaged. A final problem which can be diagnosed from black smoke is problem with the air filter. Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil.

Operating engine at greater than a degree angle. Inoperative crankcase breather. 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.

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 steady stream of white smoke during normal driving conditions points to fuel vapors, or in some cases, raw fuel exiting the exhaust. Worn or defective glow plugs, improper engine timing and defective fuel pump pressure will allow excess fuel to exit the exhaust in the form of white smoke. An engine burning coolant can be easily determined.

First question, do you have to regularly add coolant? In many cases, white smoke emanating from the tailpipe (often at idle once the engine reached operating temperature) typically means a worn out injector. Now this isn’t always the case, but after some trouble shooting we’re usually the go-to shop when diesel drivers need refurbishe rebuilt, or new injectors. The white smoke is the engine burning off all the excess oil. The fix - drain the excessive oil, and idle the engine until the smoke clears.

Depending on your mower type, draining the oil can be a pain in the ass. This may take minutes or so. I got this Briggs and Stratton oil extractor, on Amazon, makes life soooo easy.

Coolant is entering the cylinder and is being burned along with fuel. White smoke= blown cylinder head gasket. 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. In this case the coolant would end up being heated in the combustion chambers and blown.
