Disadvantages of the Mitsubishi 4G33 engine
The owners’ primary issues are related to the capricious carburetor’s malfunctions.
Additionally, the balance shaft belt and timing belt do not have the best resources.
Oil frequently seeps onto belts from gaskets and seals, corroding them over time.
The fuel pump is short-lived, and the motor mounts are damaged rather quickly.
The valves must be adjusted because hydraulic lifters are not available here.
