Because your exhaust is making white smoke, there are things you can do to fix it. To learn how to read until the end. I will also explain why white smoke comes out of your exhaust after you change your oil and what the most common causes of BMW white smoke from the exhaust are.

Why is My Car Blowing White Smoke But Not Overheating

White smoke doesn’t have to come from your car if it doesn’t get too hot. One or more of the following may be the reason why your car emits white smoke: People often get into trouble because either water or coolant or oil got into the combustion chamber. This is because of leaks. If your car isn’t overheating but is still emitting white smoke, it means there is something wrong with one or more parts of your engine. A part may be faulty and needs to be fixed or replaced right away to avoid more damage.

Can Too Much Oil Cause White Smoke from Exhaust

Yes! Too much oil makes white smoke come out of the car’s tailpipe. But the problem here is not the oil itself but how it gets into the burner. It’s more likely to leak out of the piston rings and valve seals into the cylinder and into the combustion chamber, where it is mixed with the fuel and air and then burned, making the white smoke.

Why is White Smoke Coming Out of My Exhaust After Oil Change

A white smoke that comes out of your car’s tailpipe after an oil change can be caused by three things:

In the car, there is a lot of oil in it, and it has gotten into all the parts of the engine that need it. There is too much oil in the tank, so it flows into the cylinder and is burned in the combustion chamber.

The new oil is not made of mineral oil. Synthetic oil can get rid of soot and varnish that have been stuck in the tank, valve, and cylinder for a long time. This stops the oil from spilling out. This can cause too much oil to get into the combustion chamber when the engine is cleaned.

The new oil that was used is not in line with the original manufacturer’s specifications. This could allow the oil to get through the piston rings or valve seals and into the combustion chamber, where it could be burned off.

Common Causes of BMW White Smoke from Exhaust

Your BMW’s exhaust should not make white smoke. This is a way of telling you that something is wrong with the car, so don’t do it. It can be caused by a lot of different things, but all of them are inside problems. This is a list of eight things that can make white smoke come out of a BMW’s exhaust.

1. Accumulated Condensation.

The white smoke that comes out of your car’s exhaust when you start it up in the morning is likely caused by condensation that has built up over time. When condensation builds up and burns off, white smoke comes out in small amounts. It doesn’t last long, but the smoke clears up quickly. In this case, it will fix itself.

2. Damaged Cylinder Head

There could be a crack or other damage to your cylinder head, which could make your coolant leak. Coolant leaks into the engine oil, which makes white smoke. Most of the time, when there is smoke, it has a sweet smell that you can use to help you find it.

3. Faulty Fuel Injector

The fuel injector is a tube that lets or stops the flow of fuel. If your fuel injector is broken, it could stop the flow of fuel into your car’s engine. Having a bad fuel injector will cause white smoke to come out of the car’s tailpipe when fuel doesn’t get into the engine at the right time.

4. Oil Leakage

When oil leaks into the fuel, there will be white smoke. In some cars, faulty valve seals or piston rings can let oil leak into the combustion chamber, mixing with the fuel. You can’t put oil in the combustion chamber because it’s only meant to hold air and fuel.

5. Damaged Coolant  Reservoir Tank

When a coolant reservoir tank is cracked or damaged, the coolant comes out. This is very rare, but it can happen. This leak is burned in the cylinder, which makes the car emit white smoke. If there is any damage, it doesn’t even have to be big. A little creak is enough. If you mess with the coolant tanks while working on another part of the engine, they don’t just leak. They need to be fixed.

6. Damaged Engine Block

Also, a damaged or cracked engine block can cause white smoke to come out of the tailpipe. Cracked engine blocks are the result of damage in the engine that hasn’t been fixed yet, so they happen. This is hard to find, and you’ll need to go to an auto repair shop.

7. Faulty Engine Control Unit

When the fuel injectors start firing, this causes them to start at the wrong time. Don’t worry, your fuel injector isn’t broken. It’s the engine that needs to be changed or fixed.

8. Cracked Head Gasket

The head gasket is meant to keep the cylinder head and the engine block together, but it can also leak. It is a thin piece of metal that is between them. It stops coolant from getting into the cylinder. If a head gasket gets cracked because of wear and tear, then that is why. White smoke comes out when this happens. Coolant gets into the cylinder, where it burns and then comes out as white smoke afterward

How Do I Fix White Smoke from Exhaust

There is no one-size-fits-all answer to white smoke coming out of your car’s tailpipe. However, to fix white smoke, you have to figure out which one of the eight causes above is the problem, and then fix it. You can read on to find out how to fix the different problems that led to them.

1. Fixing Accumulated Condensation

Only this one gets fixed on its own. All you need to do is be patient. Soon, the smoke will be gone.

2. Fixing Damaged Cylinder Head

The best way to fix a broken cylinder head is to buy a new one. Cylinder heads can be damaged when cars overheat, no matter what they are made of. This is true even if they are made of something else. To avoid getting a cracked cylinder head, check your car often to make sure it doesn’t get too hot.

3. Fixing Faulty Fuel Injector

You either have to change the fuel injector or clean it to fix it. When you change the fuel injector, make sure you change all of the injectors so that the engine runs smoothly. Because it is clogged you only clean the injector if you want to get rid of it. Change or clean the fuel injector if you want to do it on your own. There are simple ways to do this.

Contaminants that have built up over time are what hurts the fuel injector. If you don’t want this to happen, make sure you get your fuel from trusted stations and always change your fuel filter.
