The weight of the G4CM engine is 149.1 kg (excluding attachments). The engine number G4CM is located on the cylinder block. A strong knocking under the hood is a sign of hydraulic compensator failure. Vibration of the power unit indicates critical wear of one of the engine supports. Floating engine speed is often caused by contamination of injectors, throttle, and EGR. However, these are all minor issues, the most important thing here is to monitor the condition of the timing belt and balance. After all, the breakage of any of them almost always results in the meeting of pistons with valves.
