Excessive Smoke

Excessive Smoke

There are many reasons a diesel engine might produce smoke, in a variety of colors. From worn engine components, to damaged fuel delivery systems, when trouble arises there is typically a “smoke trail” that can help with diagnosis. For newer diesels with catalytic converters, smoke is usually not visible. For these vehicles, poor running conditions will be the most noticeable indicator of engine distress.

Black, blue, or white smoke

Depending on the nature of the problem, you may see either black, blue, or white smoke. Black smoke is likely an induction problem, either from unburned or low quality fuel, a clogged air filter, or a fuel injection issue. Blue smoke is typically related to the engine lubrication oil, burning due to mechanical malfunction of the internal engine parts. You should note that many diesels will emit a little blue smoke on start-up, which is no cause for alarm…as the engine warms up, the smoke will stop. White smoke is usually caused by poor fuel combustion, which happens with worn injectors, damaged vales, sticking rings or even damaged turbochargers.
