Disadvantages of the Mitsubishi 4G92 engine
The motor’s SOHC modification is incredibly dependable, and the valves won’t bend even if the belt breaks;
Nevertheless, the DOHC modifications are more erratic and prone to oil consumption after 150,000 kilometers of operation; the SOHC version lacks hydraulic lifters and the valves are adjusted every 50,000 kilometers;
Furthermore, DOHC versions’ hydraulic lifters break down rather quickly;
The low attachment reliability is a common issue for all engines in the series.
