  • 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?

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.
