The following is an overview of common exhaust smoke colors to help you understand when there is something wrong with your vehicle and when you shouldn’t panic.

1. Blue Smoke

When you experience blue or grey smoke from your car’s exhaust, you may be having an oil leak problem. Leaking oil ends up in the combustion chamber where it mixes with fuel resulting in a bluish smoke. Recent addition of the engine’s power output may be the cause since it may have added stress and the damaged the piston rings. This results in an oil leak.

The valve seals and cylinder walls might have worn out resulting in the bluish smoke. Take note when you are experiencing the bluish smoke. If it happens during acceleration, then the piston rings might have malfunctioned. If when you decelerate is when you encounter the smoke, then, the valve guide seals are to blame.

2. Grey Smoke

Having a think grey smoke may be a sign something is wrong with your car. This smoke can be a sign of a damaged cylinder head, damaged engine block, or a leaking head gasket. If the problem is the head gasket, you may end up with coolant in the combustion chamber, which will be burnt and evaporated. This will leave the engine without coolant which will make it overheat. In case of an engine block or damaged cylinder head, your engine may fail altogether. That is why you should seek the services of a professional when you notice persistent emission of grey smoke from your car.

3. Black Smoke

Your car is burning more fuel when you are experiencing black smoke from the exhaust. Seek professional assistance to determine and fix the problem causing this problem.
