Why do I have white smoke coming from my head gasket?
It does not take much oil to create a large cloud of smoke, so you may not even notice the oil level went down if you were to check the dipstick. White smoke is usually antifreeze burning. That indicates a crack in the head gasket. Blue smoke is burning oil. That could be a number of things from piston rings to valve guides .
Why is there smoke coming out of the exhaust after an oil change?
This can occur if coolant is leaking into the head. It could also be as simple as water entering the exhaust or carburetor after the engine was pressure-washed. On the other hand, if the smoke is a bluish white, oil could be bypassing the rings on the piston or valve seals and being burnt in the combustion chamber.
Why is there white smoke coming from my diesel engine?

What causes a car to have white smoke coming from the exhaust?

Blue-gray or gray-white smoke. Blue-gray or gray-white smoke usually means the engine is burning oil. If you have a turbocharged engine, a faulty turbo seal could be causing this, but if you have a more common engine, it’s likely one or more of the following problems:
Why do I have Sweet Smoke coming from my exhaust?
It happens that this gasket becomes bad and starts to leak. If you have a bad intake manifold gasket, you will often smell sweet smoke from the exhaust gases. If your exhaust smoke smells sweet, it’s most likely a condensed coolant you are facing.
Irregular fuel injection can cause white smoke to be emitted from the tailpipe. One of the main causes of white exhaust smoke is engine coolant leaking to different parts of the engine. White smoke will be released when even small amounts of coolant enter the combustion chamber.

What to do if your tailpipe is smoking?
If you need to replace your valve guides, on the other hand, it’ll be significantly more expensive. The amount of labor required is much greater, and the parts cost is higher as well. Another option is to replace the cylinder head. Worn piston rings or cylinders: Piston rings seal the space between the piston and cylinder wall.
Where does the gas go when it comes out of the tailpipe?
Along the way, the gases travel through the catalytic converter, where any remaining fuel is converted to water to reduce emissions. Finally, the gases exit through the tailpipe. When everything’s working properly, this exhaust is colorless. But if something is amiss, you’ll see a cloud of smoke coming out of the back of your car.

What does it mean when your car has white smoke coming from the exhaust?
White smoke. Some white exhaust smoke is normal, especially when you first start the car. Condensation can turn to vapor, providing what looks like white exhaust. But excessive white smoke likely means coolant is leaking into the engine combustion chambers.

Why do I have smoke coming from my exhaust pipe?
The first thing you should do is to taste or smell the smoke coming from the exhaust pipe. If it has a sweet smell, it’s coolant. If the smoke doesn’t smell or taste anything more than water, it’s most likely condensation, and the smoke will go away after the car is heated up.
Why does the exhaust smell like burnt oil?
The exhaust will also have a burned oil smell. If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell.

Why do I have white smoke coming from my exhaust pipe?
White smoke from the exhaust pipe on startup, idle, or acceleration tells us that coolant or water is getting vaporized in the exhaust pipe. You can also carefully smell the water or smoke from the exhaust; if it smells sweet, it’s most likely coolant, and in this case, you have a bigger problem.

What causes the smoke to come out of the tailpipe?
If oil were to ever leak out of your piston rings or valve seals, then it would flow into the internal combustion chamber along with the fuel. Once the fuel and oil get mixed together, it will cause to come out of the tailpipe. The color of the smoke will actually be blue-ish but it will appear to be white smoke to some people.

Remember to only perform this step when the intake gasket is working fine. After that, we will come to the head gasket.
Why does my car have a white smoke smell?
If the white smoke is coolant, your car is definitely having a crack in the cylinder head or a leaky head gasket, along with a sweet smell.

What causes white smoke after a head gasket repair?
After the repairs to the engine are made to fix the leaking head gaskets the engine can then be started. Once started the exhaust heat will now start to burn off the coolant and water that was pushed into the exhaust system. When this fluid is heated it will come out the exhaust as white smoke or steam.
