Our speciality

Engine
overhauls.

Full engine tear-down, inspection and rebuild for maximum performance and reliability. Petrol and diesel, every brand – measured, machined and rebuilt to factory specification.

Repair, overhaul or replace?

Not every noisy engine needs a rebuild. We test first – compression, leak-down, oil pressure and a full scan – and give you an honest recommendation with the costs side by side.

Warning signs

When an engine is asking for help

Caught early, many of these are repairs. Ignored, they become a rebuild – or a new engine.

  • A knock that gets louder with revs
  • Blue smoke on start-up or when accelerating
  • Milky oil or coolant disappearing
  • Oil pressure light flickering at idle
  • Using more than a litre of oil every 1 000 km
  • Low compression on one or more cylinders

How we rebuild

Five stages. No shortcuts.

Every overhaul follows the same process – and you get photos on WhatsApp along the way.

  1. Stage 1

    Diagnose

    Compression and leak-down tests, a full scan and an honest opinion: repair, overhaul or replace.

  2. Stage 2

    Strip down

    The engine comes out and is stripped on the stand. Every part is cleaned, inspected and photographed.

  3. Stage 3

    Measure

    Bores, crankshaft journals, bearings and the head are measured against factory specification.

  4. Stage 4

    Machine & rebuild

    Machining where needed, then assembly with new bearings, rings, seals, gaskets and the correct torque procedure.

  5. Stage 5

    Fit & test

    Refitted, filled, primed and coded. We run it in, road test it and give you the running-in instructions.

What a full overhaul covers

Everything that wears – replaced

The exact list depends on what we find after strip-down and measuring. You approve the final quote before we order parts.

  • Engine removal & refitting
  • Full strip-down & inspection
  • Main & big-end bearings
  • Piston rings & gaskets
  • Oil pump & seals
  • Cylinder head skim & valve work
  • Timing kit (belt or chain)
  • Fresh oil, filters & coolant
  • Injector coding & adaptations
  • Road test & running-in advice

Common-rail diesels

Bakkies, SUVs and German diesels – injectors, rails, turbos, EGR and full rebuilds.

German petrol engines

Mercedes-Benz, BMW, VW and Audi petrol engines, including timing-chain jobs.

Japanese & Korean workhorses

Toyota, Nissan, Hyundai and Kia engines that just need to keep running.

Overheated engines

Warped heads, blown head gaskets and cooling faults – fixed at the cause.

From our workshop

Real engines. Real rebuilds.
