Signs Your Truck’s Engine Needs Attention

Strange Noises

Unusual engine sounds are often a red flag. Common issues include:

• Knocking noises: This may indicate improper fuel combustion, potentially due to:
  • Routine combustion
  • An exhaust or valve leak
  • Valve damage
  • Broken bolts
  • Injector problems (fuel knock)
• Grinding sounds: Typically point to issues with internal engine components.

If you hear any odd noises, contact a Heavy Equipment Specialist like SuperService™ immediately to prevent further damage and costly repairs.

Unusual Smoke from Exhaust

The colour and volume of exhaust smoke can indicate engine problems:

• Blue smoke: Oil burning in the engine, possibly caused by:
  • Faulty valve seals
  • Damaged piston rings
• White smoke: Often a sign of a coolant leak, which could mean:
  • Blown head gasket
  • Crack in the engine block
• Black smoke: Indicates excess fuel burning, possibly due to:
  • Faulty fuel injectors
  • Clogged air filters

Unusual smoke should never be ignored, even if the truck appears to run fine.

Loss of Engine Power or Performance

Indicators of engine trouble include:

• Loss of power when accelerating or pulling a heavy load
• Possible issues with air or fuel supply, or the combustion process

A noticeable loss of engine performance means a component could be failing and should be checked by a professional.

Dashboard Warning Lights

Modern trucks have sensors to monitor engine performance. Key points to consider:

• Check engine light on? The check engine light is one of the most notorious and frequently misunderstood warning lights. It can signal a range of issues, from minor problems like a loose fuel cap to more severe engine-related troubles. When this light comes on, it’s best to have your truck’s engine system thoroughly inspected to determine the exact issue.

Take warning lights seriously and have your truck inspected by a qualified mechanic to prevent problems worsening.
