Disadvantages of the Mitsubishi 4G62 engine
Unreliable belts, particularly balance shaft belts, are the primary cause of the issues;
Here, hydraulic lifters are quickly disabled by low-quality or outdated oil; a dirty throttle or idle speed controller is typically the cause of floating engine speeds;
The destruction of the power unit’s pillows is typically the cause of its vibrations;
Cracks in the intake and exhaust manifolds are a common complaint on specialized forums.
