Disadvantages of the Mitsubishi 4G62 engine
- The main problems are caused by unreliable belts and especially balance shaft belts;
- Low-quality or old oil here quickly disables hydraulic lifters;
- The cause of floating engine speeds is usually a dirty throttle or idle speed controller;
- The culprit of the vibrations of the power unit is most often the destruction of its pillows;
- There are a lot of complaints on specialized forums about cracks in the intake and exhaust manifolds.
