Bring Your Engine Back to Life

Mechanic Working on A Car Engine — Haigh Truck & 4WD Repairs In Orange, NSW

When your engine loses power, starts burning oil or shows signs of serious wear, a rebuild can save you thousands compared to replacing the whole vehicle. For older trucks, work-ready utes and commercial 4WDs, a full engine rebuild is often the smartest way to keep your vehicle working without compromise.


At Haigh Truck & 4WD Repairs in Orange, we rebuild diesel and petrol engines with accuracy, care and over 30 years of trade experience. A proper rebuild restores performance, improves fuel use and helps pass compliance checks. Whether you’re dealing with low compression, knocking or overheating, we’ll get it sorted. We also offer diesel diagnostics, truck repairs and defect clearance services.

What’s Involved in an Engine Rebuild

We inspect and rebuild diesel and petrol engines with a focus on long-term reliability and performance.

  • Top-End Repairs
    We recondition cylinder heads, replace gaskets and check valve timing. Common for oil leaks, smoke or loss of compression.
  • Bottom-End Overhauls
    Crankshaft, pistons, rings and bearings are replaced or machined. This restores engine balance and oil pressure.
  • Cooling & Lubrication Systems
    We replace water pumps, radiators and oil lines. A healthy cooling system is critical for any rebuilt motor to perform.
  • Full Engine Rebuilds
    When major wear or failure occurs, we tear down the engine, re-machine components and rebuild to factory spec or better.
