If you own a car, it becomes a necessity that you know about the certain technical know-how of your car too. If you understand well, why, and how do certain things happen to your car, you would surely be in a position to avoid and get rid of unnecessary expenses that can be needed for your car. If you maintain your car well, you will certainly be avoiding up unnecessary bills and unneeded stress. In this article, we will provide you with detailed information about the main causes that lead to white smoke release from your exhaust and what are the ways in which you can fix them with ease. Let’s proceed.
What causes white smoke to get released from your car’s exhaust?
If your car is expelling white smoke from the exhaust, there are some causes that might lead to such cases. Let’s have a look at those causes.
Cracked cylinder head
If you notice that the white smoke that gets expelled from your car’s exhaust is smelling sweet, it simply means that the coolant has got mixed up with the engine oil. This happens due to a cracked cylinder head or a cracked engine block or a head gasket failure. The three scenarios mentioned above take place due to overheating in a car. Due to a cracked cylinder, the coolant enters up one or more cylinders. In certain cases, the coolant also gets entered into the combustion chamber. The occurrence of a cracked cylinder happens because of the presence of a dirty coolant. It also happens owing to the reason that the cooling system is not properly maintained or if you have been running the car with insufficient coolant levels. Simple wear and tear can also cause leaks within the head gasket that can lead to coolant getting entered into the engine chamber.
Faulty timing of the injector pump
If you drive a diesel-fueled car and you notice white smoke coming from your car’s exhaust, it means that the fuel pump injection timing is not working. When the fuel pump pumps up the diesel fuel into the cylinders of a diesel engine, its timing is a crucial and key factor to be considered. Timing helps to ensure a high level of fuel efficiency when the fuel is being injected. It also helps in preventing the chances of the overrun of diesel. In case the timing is off, it may lead to white smoke that will be expelled from your car’s exhaust.
Presence of a bad fuel injector
In cases in which the fuel injector gets stuck open or gets leaked from the O-ring, it leads to the presence of too much fuel in the combustion chamber. This excess amount of fuel does not get burnt up properly in an engine. As a result, it produces thick and grey smoke. In certain cases of this happening becoming more severe, smoke that is black to dark grey in color gets produced from your car’s exhaust.
Does white smoke come from exhaust mean that the oil is getting burnt up?
Certainly not. If the oil gets leaked from the piston, it results in an oil that seeps into the combustion chamber. Further, this oil gets mixed up with fuel that results in a blue-colored smoke coming out from your car’s exhaust.
How to fix up the white smoke coming out from your car’s exhaust?
If your car is expelling white smoke excessively, you must follow the given steps.
Inspecting the intake gasket
The purpose of an intake manifold is to get the coolant or combustion mixture evenly distributed to each port present in the cylinder heads. In order to seal the manifold to the head, there is a gasket. If this gasket gets damaged the coolant gets entered into the port and subsequently moves into the combustion chamber. In such cases, you should remove the intake manifold and examine the gasket to ensure that there is no rust or leakage. If it turns out to be in good condition, you should follow the step that follows.
To properly check the head gasket, examine further
Apart from the intake gasket, there is a head gasket that helps in sealing the cylinder head to a block. Through this, the coolant flows into the cylinder. If this part gets damaged, the coolant enters into the combustion chamber that again results in the expelling of white steam from your car’s exhaust pipe.
Looking for cracks in the cylinder head
If your car gets overheated, the cylinder head of your car that is made up of aluminum might break. In such cases, you should immediately get it changed if it is appearing broken or damaged. But at the same time, you should ensure that the cylinder head gets sealed evenly along with the engine block and head gasket. In order to fix such a problem, you should choose to take your car to an experienced mechanic as it might prove to be a complicated and complex job for a novice.
