Another successful Mercedes OM651 rebuild completed!
This 2015 Mercedes-Benz W212 arrived with a snapped timing chain. We removed the engine and carried out a full inspection to identify all underlying issues.
* Engine removed and fully inspected
* Intake manifold and EGR system professionally cleaned
* Cylinder head pressure tested, skimmed, and rebuilt with replacement valves where required
* Injectors tested – 3 out of 4 were found to be heat-damaged due to a completely blocked DPF
* New timing chain kit installed
* New high-pressure fuel pump sprocket fitted
* 4 brand new Delphi injectors installed and coded
To complete the job, we also carried out our AdBlue, EGR & DPF solution, followed by a Stage 1 remap, leaving the vehicle running smoothly with restored performance and reliability.
If your Mercedes is showing timing chain noise, DPF issues, injector faults, or loss of power, get in touch with us.
