Excess Smoke

Diesel Engine Troubleshooting – Solution here:

• Excess smoke from the engine is most often an indicator of engine trouble forming. The various smoke colours can help to troubleshoot more specifically what the problem could be.
• White smoke can mean the engine timing is off or the engine compression is weak.
• Blue smoke can mean worn cylinders, piston rings and valves.
• Black smoke can be an indicator of dirty air filters, bad injectors, a turbo problem or a problem in a cylinder head (insufficient fuel to the cylinder).
