What a Mercedes Engine Rebuild Involves
Our engine rebuild service returns your Mercedes-Benz engine to factory specifications - or better. Every rebuild follows a strict, documented process carried out in our purpose-built workshop.
The process is not a simple “overhaul”; it is a complete disassembly, inspection, precision machining, replacement of all wear items, and reassembly to original tolerances. We use genuine or OEM-quality parts and factory-specified tools for every job.

Our Engine Rebuild Process
- 01
Vehicle Arrival & Assessment
We perform a full diagnostic check and compression test to confirm rebuild requirements. We then provide a fixed-price quote before any work begins.
- 02
Engine Removal & Strip-Down
The engine is carefully removed and completely disassembled. All parts are cleaned using thermal and shot-blasting methods to reveal wear and damage.
- 03
Precision Measurement & Machining
Every component is measured to micron tolerance. Cylinders are bored and honed, crankshafts ground, and deck surfaces milled to factory specs.
- 04
Parts Replacement & Assembly
All wear items - bearings, piston rings, seals, gaskets - are replaced with genuine or OEM parts. Reassembly follows Mercedes-Benz torque and angle settings.
- 05
Dyno Test & Calibration
Every rebuilt engine is run on our dyno for a full break-in cycle. We check for leaks, verify performance, and calibrate engine management.
- 06
Re-fit & Road Test
The engine is re-installed, fluids filled, and a comprehensive road test is performed. Only when everything is perfect do we hand the car back.
