Disadvantages of the Mitsubishi 4G32 engine
- Most versions of the engine are equipped with a carburetor, which has enough problems;
- Belts have a low resource here, both the timing belt and the balance shaft belt;
- This is facilitated by oil, which constantly pours onto the belts from gaskets and seals;
- The power unit supports and the fuel pump in the gas tank also serve for a short time here;
- There are no hydraulic lifters, so the valve has to be adjusted every 50 thousand km.
