Key Indicators Your Engine Needs an Overhaul

When your generator or industrial engine starts losing power, burning more fuel, or producing unusual smoke, it might be time for an overhaul. At Sparrow Technical Services Limited, we know that early detection can prevent costly breakdowns and extend equipment life.

What Is an Engine Overhaul

An overhaul involves disassembling, cleaning, inspecting, and rebuilding the engine to restore it to optimal performance. Depending on the condition, this can be a top overhaul (focused on pistons, valves, and gaskets) or a major overhaul (complete teardown including crankshaft and bearings).

When to Schedule an Overhaul

Watch for these warning signs:

  • Excessive oil consumption or visible leaks
  • Low compression and poor power output
  • Knocking or unusual vibration
  • Increased fuel usage
  • Heavy exhaust smoke
  • Metal particles in oil filters
  • High operating hours beyond service limits

If two or more are present, it’s time to plan a professional inspection.

Sparrow’s Pro Tip

Always conduct oil analysis and compression testing before and after an overhaul. These tests verify the engine’s internal condition and confirm that your rebuild meets OEM standards.
