Disadvantages of the Hyundai G4CM engine
- A strong clatter under the hood is a sign of failure of the hydraulic lifters;
- Vibration of the power unit indicates critical wear of one of the engine mounts;
- Floating engine speeds are often caused by contamination of the injectors, throttle and idle speed controller;
- However, these are all trifles, the main thing here is to monitor the condition of the belts: timing and balancers;
- After all, the breakage of any of them almost always turns into a meeting of pistons with valves.
