It comes equipped with a modern Rotary Electronic Actuator (REA).Before bolting a new or remanufactured unit onto the manifold, perform these essential steps to prevent instant warranty failure: Inspect Injector Seals: Blown copper injector washers cause severe oil carbonisation (sludge) in these engines, which starves the turbo bearings of oil. Always Replace the Oil Feed Pipe: Microscopic carbon debris easily blocks the narrow internal oil lines feeding this high-speed GTD cartridge. Check the DPF: A restricted Diesel Particulate Filter (DPF) will cause high exhaust backpressure, forcing heat back into the turbocharger turbine housing and killing the oil seals
