- Step 2: Check the head gasket. The gasket seals the cylinder head to prevent coolant from entering the cylinder.
- Step 3: Check the cylinder head.
Are white exhaust gases harmful?
White smoke may not be of concern if it is as fine as vapor. This is likely due to the normal buildup of condensation in the exhaust system. This type of smoke disappears quickly. However, thicker smoke is a major problem and can be caused by burning engine coolant.
What does the white smoke coming out of the exhaust mean?
White combustion gases
This means that the coolant somehow leaked into the combustion chamber. This can be caused by several things, such as a blown head gasket, a leaking engine block, or a leaking cylinder head.
What causes exhaust gases?
If your engine is burning coolant due to a blown head gasket, damaged cylinder head, or broken engine block, you could be in trouble. Thick white smoke from the muffler indicates a coolant leak, which can cause overheating and put the engine at serious risk of damage.

What color should the exhaust gases be?
What causes unburned fuel in the muffler?
Unburned fuel enters the exhaust system.
This can overheat the inverter well beyond its normal operating range. Possible causes are incorrect fuel mixture, incorrect weather conditions, bad spark plugs, faulty oxygen sensor, sticking float, faulty fuel injector or faulty valve.
