Disadvantages of the Mitsubishi 4G32 engine
The carburetor found in the majority of engine models has enough issues;
Both the timing belt and the balance shaft belt have limited resources;
Oil, which continuously pours onto the belts from gaskets and seals, makes this possible;
Here, the fuel pump in the gas tank and the power unit supports also serve a brief purpose;
The valve needs to be adjusted every 50,000 kilometers because there are no hydraulic lifters.
