Disadvantages of the Mitsubishi 3G83 engine
The most well-known issue with this motor is the oil burner because of rings;
Even with a short drive and low oil level, the crankshaft liners rotate;
Maintain a clean cooling system to prevent the gasket from overheating;
Because the timing belt bends the valves when it breaks, check its condition more frequently;
Additionally, the engine’s fuel system and catalyst cannot withstand subpar gasoline.
