Why Does My Car Throw White Smoke When I Accelerate?
There are many causes why your vehicle would billow smoke while accelerating, but some of these reasons are just mild, and you can resolve it quickly, and you will not experience any problems. However, there are also some cases where the white smoke from your exhaust causes a significant problem and can lead to a severe issue that you need to fix.
1. There Might Be Oil Leaking
If the engine oil leaks out of your valve seals or your piston rings, this can mix with the fuel in the internal combustion chamber. If the oil and the fuel are combined, the smoke will start to go out from the exhaust. Your exhaust will likely blow out a bluish hue of smoke, but the smoke is white in most cases.
You must repair this leak as soon as you can. If the components of your engine will not be adequately lubricated with oil, these components will start to wear down, and they can get damaged.
2. There Might Be A Cracked Cylinder Head
If your vehicle has a cracked cylinder head, the coolant will seep into it. It does not have to be a large crack. Even if the crack is tiny, it already takes a small amount of coolant, and it will seep out and mix in with the oil.
If this issue occurs, the engine oil will then become contaminated. White smoke from your exhaust pipe is the first indicator that your oil is contaminated.
3. There Might Be Condensation Burn Off
If there is white smoke, it can just be because of the accumulation of condensation. Usually, this white smoke will come out on cold days. If you start the engine, smoke will appear.
But after about thirty seconds to a minute, it will also disappear. But if the smoke will not go away and is present if you are accelerating, it might mean a different issue.
4. There Might Be An Internal Coolant Leak
If your engine is warmed up and there is white smoke from your exhaust if you are accelerating, then this can mean that a coolant is leaking from one of the piping or engine of your vehicle. If the coolant leaks, the engine will not cool itself properly, and it will not supply enough lubrication on the moving parts of the components. This will then result in overheating.
The cause for this is that there is damage to the internal engine components. Even if there is a fracture and it is insignificant and tiny, it will allow the coolant to seep out and then pollute the majority of your engine.
As a result, there is white smoke from the exhaust. Also, if there is a coolant seeping from your vehicle and the coolant reservoir is low, your engine will overheat.
5. There Might Be An Error In The Engine Control Unit Or Ecu
If your vehicle has a malfunctioning engine control unit or ECU, the timing of the fuel injectors will be thrown off. As a result, it’ll cause white smoke to go out of your exhaust.
With that, you might need to repair the engine control unit to adjust the fuel injector timing. You can resolve the problem by unplugging your vehicle’s battery for a few minutes.
6. There Might Be Failing Fuel Injectors
A malfunctioning fuel injector is jammed open or has an o ring leak that will supply too much fuel in the vehicle’s combustion chamber. Too much fuel cannot be burned correctly in the engine, but it will escape through the exhaust.
7. There Is Transmission Fluid
If you detect white smoke from the exhaust while accelerating, this can mean that your vehicle’s engine is absorbing too much transmission fluid from the line or vacuum hose. This will result in burning oil and a burnt smell.
8. There Might Be A Cracked Engine Block
A cracked engine block is the worst-case scenario. These are the kinds of issues that are the most expensive. You will understand this if the issue.

Can You Drive A Car With White Smoke?
You must not continue to run your vehicle. If your vehicle has a cracked or a failing gasket, this can lead to more contamination or overheating.
You can check the coolant level. If it is low and has no leak, you might have a head gasket leak or crack.
Summary
