[Fixed] White Smoke From Tailpipe When Accelerating

White Smoke From Tailpipe When Accelerating

If you’re experiencing white smoke from your car’s exhaust, you may be dealing with a serious issue that requires the attention of an auto mechanic. While it’s not uncommon to see white smoke coming from a tailpipe, especially in colder weather when the engine isn’t properly warmed up yet, some circumstances indicate there’s more to it than that.

This article will help you identify the cause of white smoke from tailpipe when accelerating. While some smoke is normal, it can become excessive and a sign of a problem that needs to be addressed.

On cooler days, whitish smoke is usual but should clear away in a very few minutes. When that doesn’t happen like that, you know there’s a problem.

What Could Exhaust White Smoke Indicate?

When you see thick white smoke coming from your tailpipe, it may be a sign that coolant or water entered your engine. This is never a good thing because it can cause a buildup of steam pressure in the cooling system, which in turn can lead to serious problems with the engine. To avoid this, make sure that your car is well maintained. It may be time to get a tune-up as well, especially if you frequently leave the key in the ignition, while the engine is off.

Exhaust White Smoke: What is the Cause of It?

Leakage of Coolant

You can stop the white smoke instantly with a coolant leak. One of the most prevalent causes of white smoke is coolant leakages. A coolant leak can be a result of damages or cracks in the coolant reservoir tank. The damage could have occurred when your mechanic accidentally applied too much pressure on the tank. Or maybe you encountered a hard hit while driving on portholes. The leaking coolant will start floating on the top of the reservoir, causing the white smoke. The white smoke is caused by the floating coolant, which may be in turn toxic to breathe.

Head of a Cylinder That Has Cracked

A cylinder head seals the engine block, which contains the burning fuel, and houses the valves that supply fresh-breathed air to the engines. It also contains more valves that release the used, stale air from the engine. In harsh situations, the cylinder head might shatter, causing problems related to a damaged head gasket or a broken block. While most of all heat generated by the burning of fuel/oxidizer is converted to thermal air, car motors heat up quickly. This type of heat doesn’t only pose a danger for the car engine but also for the safety of the driver. During hot, high-speed driving, the heat caused by burning fuel in the cylinders can cause the car’s brakes to freeze or the car’s electronics to fail.

Head Gasket with a Crack

The head gasket is an important piece of metal found in most engines; between the top and bottom parts of the engine. This part helps to form a seal and prevents leaks. It is the main function of the head gasket and it helps in keeping the engine coolant from leaking out of the cover. One of the most common reasons for a head gasket to crack is wearing and tear. When this happens, coolant leaks out. The condensation isn’t contained within the parts of the engine where it’s supposed to be, but instead, it finds its way into the engine’s cylinder, where it’s burned. Fixing a cracked head gasket can be tricky and should be done as soon as possible.

Transmission fluids or coolants are the advisable responses in this situation. The transmission liquid can be found by looking for a vacuum hose sucking the liquid from the vehicle, making it become smoke white. The exhaust will also have a burned oil smell while the coolant will smell like water. This means that water is now inside the engine. Do not use a compressed air can try to clear the oil. If air builds up in the can and won’t come out, the tube can become damaged and leaks oil into the engine.

Depending on whether the coolant is low or the motor has been running hot, there are several different things you can do to potentially get temporary relief. On the off chance that your coolant smells sweet, you should pressure test your cooling system. If the coolant is low or the car has been overheating, your vehicle may have a broken head gasket or chamber head, in addition to a sweet smell.

You must exchange it for it to function normally once again. Once the liquid is the problem, drivers can solve this issue by replacing the transmitting vacuum completely as well as replacing its module valve.

However, if you want to correct the level, add liquid until it reaches the appropriate level. This will help reduce the tendency of the overflow of white smoke from the exhaust when accelerating.

Some Simple Solution to These White Exhaust Smoke

The Fuel Injector Should Be Cleared or Replaced

You might be dealing with clogged fuel injectors if your car is out of gas, the engine won’t start and is likely to smell like gas. This is common with cars that are old or haven’t been taken care of properly. Here’s the good news: there are commercial options that can help you fix your car with this kind of issue. Unless your fuel injector malfunctions for reasons other than blockages, maybe it has approached its decline stage, and now the only option would be to replacing it.

Examine each Intake Gasket

When you see white smoke coming from your vehicle’s exhaust, the first thing to check is the admission gaskets. There are two types of these gaskets: one at the initial segment of the engine and one inside the vehicle. The job of these gaskets is to seal your vehicle’s engine to its head, along with circulating air and its coolant. When they are not properly sealed, they allow unwanted and highly dangerous fumes into the vehicle’s cabin. A loose gasket can affect the performance of your vehicle.

As a rule of thumb, the more advanced an intake manifold is, the tighter the intake gasket should be. To check if your gaskets are in good shape, check them by looking at the exhaust valves. If the gasket or flange is loose, you will not be able to pull the gasket outward.


Thin white flames billowing from vehicle exhaust may be okay, as long as they’re contained. But if it becomes thick and lingers, you should start giving heed to the engine. If you are doing manual work, you will need to open your hood to clear the smoke away from the engine. Make sure to get a breath of fresh air while the smoke dissipates.
