You should never ignore something like this as you drive your car. You need to find out what’s really going on and fix it if necessary. In this piece, we will talk about white smoke in depth and cover the whole issue.

The Meaning of the White Smoke

white smoke from exhaust what you should do the answer-2

When you see white smoke coming out of the tailpipe, you should be worried. The size of the thickness will tell you a lot about what the problem is. Most of the time, white smoke comes from condensation building up in the exhaust pipe.

If the smoke is really thin, it will go away right away. At this point, you shouldn’t be worried about anything. If there is a lot of smoke, it will be hard. If there is a problem with the engine coolant, it could make thick white smoke.

Thick white smoke can cause a lot of damage to your car. Here are some things that can go wrong with white smoke:

Cranked engine block

Damaged cylinder head

Head gas blown


Don’t ignore the problem if you see white smoke coming out of the exhaust pipe. For example, if your coolant leaks, it could cause a lot of damage to your car.

Causes of the white smoke

White smoke is a bad sign because it means that something is wrong with your car. There are different ways to look at it to figure out where it came from.

1. Leaking Coolant

If your coolant is leaking, you might see white smoke, especially when you are driving. It’s interesting that it might not be clear when the car starts. The burning coolant could get too hot, causing this not-so-great smoke.

When the engine oil and coolant are mixed together, they can make the smoke look like milk. As the coolant gets into the combustion chamber, white smoke is going to come out.

Also, if there is no coolant, the engine may get hot enough to make white smoke. Also, you should know how hot or cold the car is. It’s dangerous to drive a car that doesn’t have a coolant. If the engine gets too hot, the gasket may break because it won’t seal well.

So, the engine will heat up faster, which will hurt the parts inside. You should do something now to avoid the consequences.

2. Condensation

Condensation happens often, especially when it’s cold outside. Do not get scared if you start your car and see white smoke coming out of it. The cold weather could be causing the smoke. It happens when hot gases meet cold air in the open air.

Because when steam and water droplets meet, they make white smoke. After you’ve been driving for a while, the white smoke will go away. If you live in a warmer place, you might not run into this problem. It is normal for people who live in places where it is colder.

3. Broken Fuel Pumping Injection

The broken injector is something that all diesel-powered cars have. It could cause a lot of white smoke to come out of the tailpipe. The biggest problem is that the fuel pump injector is broken.

You can look at the injector and maybe change it if needed. A professional may be needed for this. It’s not just for people who just started driving. Call the mechanic and let him fix the problem however he thinks it should be done.

4. Valve Seal or Piston Ring leak

When the piston rings are broken, oil can leak into the combustion chamber. When it gets into oil, it will start to burn. Because of this, the pipe will start to smoke white or blue smoke.

You should take the car to a repair shop. At this level, you should never hold the cylinder head with your bare hands because it will be very hot. If you check the coolant and it seems fine, you should look at the pressure in the coolant system.

5. Incorrect injector pump timing

The injector pump pressure and the engine should work together in a very precise way. When the timing is wrong, the fuel in the cylinder won’t burn right. In the end, a cloud of white smoke will come out.

6. Complications from other parts

If the white smoke comes up while you’re driving, watch out for your safety. There could be an issue that is hard to solve and will cost a lot of money. For example, the head gasket, cylinder head, or fuel filter could be broken.

Also, white gas can come out of an engine that is broken or clogged. All of these problems cost a lot to fix and replace. If you want to avoid more costs, you should act right away.

Maintenance is one way to get ready for these kinds of emergencies. The process could find the problem and fix it before it gets too bad. By doing this, you’ll be able to save more money for other repairs on your car.

When the engine is not doing anything, white smoke can come out of it. If oil gets into the combustion chambers of the engine, it will smoke. You can tell because oil that is being burned can cause explosions.

As soon as you notice that oil is leaking, you should fix it. If you wait too long, it could hurt the spark plug and do a lot of damage to your car. In general, white smoke can be caused by unburned fuel in the engine.

How to Fix the Issue

white smoke from exhaust what you should do the answer-3

There are things you can do to fix your car to get around the problem. You could also take the car to your mechanic to get it fixed. You can fix the problem by taking the steps below.

1. Inspect the intake gasket

Most of the time, the gasket seals the cylinder. If the gasket breaks, coolant can get into the combustion chamber. If there is such a problem, white smoke will come out of the car while you are driving. How do you make it better?

First, you should look at the intake gasket. If you find rust or a leak, you should fix it. If everything is going well, you can move on to other steps.

2. Examine the Head Gasket

This step should only be taken if the intake gasket is in good shape. The head gasket seals the head of the cylinder to limit the flow of coolant. If it leaks, the coolant will get into the chamber where the fuel is burned.

The result is a cloud of white smoke coming out of the exhaust pipe. If this part turns out to be fine, you can look at the cylinder.

3. Examine the cylinder head

Aluminum is used to make the cylinder head. If it gets too hot, it can easily break. The cylinder head has a simple job. It will join the head gasket to the block of the engine. The bad news is that you have to buy a new cylinder head every time it breaks.


Everyone wants to be able to drive a safe car. But there are times when the car can break down. As a good driver, you should figure out what’s wrong and fix it right away. If your car’s exhaust is making white smoke, you need to fix it.

Too often, people don’t get to the bottom of the problem. If the problem is caused by condensation, your car won’t be hurt. You need to check some other parts that, like the broken cylinder head, can cause a lot of damage.

In this case, you might need to replace it to keep your engine from getting worse. At last, you can relax when your car is in good shape. Still, you’ll have a good time riding. Happy riding.
