Smoke Means Trouble

Diesel engines are known for their reliability and performance, but excessive wear and tear can lead to trouble. Beyond seeing an illuminated check engine light, smoke serves as a telltale sign that something is wrong. Understanding the different colors of smoke will help pinpoint the issue to determine what light-duty diesel repairs are needed. Black smoke indicates issues like malfunctioning fuel injectors and injection pumps or needing EGR valve repair, replacement, or cleaning. These issues result in an improper air/fuel mixture and a rich-running engine, which should be addressed quickly to prevent further damage. Blue smoke indicates engine oil burning, an emergency caused by damaged valve guides/seals or piston rings. Lastly, white smoke hints at coolant leakage into the combustion chamber, potentially leading to overheating. These issues necessitate professional light-duty diesel repair services from a knowledgeable team like ours. If you observe smoke or engine soot buildup, don’t hesitate to stop by our location at 10821 US Highway 84 East Thomasville, GA 31757 so we can have a look. We specialize in light-duty diesel truck repair and promise to quickly have you back on the road at a price you can afford.
