How To Pinpoint Automotive Problems Using the Exhaust

Is Your Exhaust Smoke a Strange Color?

Yes, that’s a real question. Various problems in the vehicle can cause your exhaust smoke to change color, like blue. The problem is, each color can mean a number of things. We’re going to teach you what causes exhaust smoke to color change and what you should look out for.

1. Black or Gray Exhaust Smoke

Incomplete fuel combustion creates a black or charcoal-gray smoke that works in with the exhaust. Possible Causes:

•   Clogged air filter

•   Ignition timing is off

•   Blocked exhaust manifold

•   Oil leaking into exhaust system

•   Carburetor, choke, fuel injection or emission system is malfunctioning

2. Blue Exhaust Smoke

Burning engine oil usually turns exhaust smoke blue. Possible causes:

•   Oil is leaking into the combustion chamber

•   Worn piston rings, valves or cylinders aren’t working properly

3. White Exhaust Smoke

Coolant, water or both are being vaporized in the combustion chamber. Possible causes:

•   Engine is running too cold

•   Head gasket is leaking

•   Cracked engine block or cylinder head
