Disadvantages of the Mitsubishi 4G92 engine
- SOHC modification of the motor is very reliable and even if the belt breaks, it does not bend the valves;
- However, the SOHC version does not have hydraulic lifters, the valves are adjusted every 50,000 km;
- DOHC modifications are more capricious and prone to oil consumption after 150,000 km of run;
- In addition, hydraulic lifters in DOHC versions fail relatively quickly;
- A common problem for all engines of the series is the low reliability of attachments.
