Volvo Truck Tech Engine OverhaulIf you aren’t getting the fuel economy you’re used to or your engine brake performance has dropped, you may be surprised to learn why. That’s because these are two of the eight signs your truck’s engine needs an overhaul. Engine overhauls are usually scheduled every seven to 10 years or 800,000 to 1 million miles, and offer a cost-effective way to breathe new life into an older engine. 

If your truck is running rough, using excessive amounts of fuel or not accelerating like you’d expect, it may be time for an engine overhaul. Here are eight specific signs to watch for:

  1. Blue or black exhaust – One or more cylinders may be burning oil, or your fuel is running too rich or lean
  2. White exhaust – Coolant may be burning in one or more cylinders
  3. Engine knocking – Combustion timing may be off in one or more cylinders, or oil contamination may have occurred
  4. Reduced acceleration/hard start – Possible loss of cylinder compression
  5. Increased oil consumption – The engine may be leaking or burning oil; either situation isn’t good
  6. Low fuel economy – Loss of cylinder compression or over-fueled cycles
  7. Low oil pressure – Oil may not be reaching all the components
  8. Poor engine brake performance – Possible loss of cylinder compression
