Disadvantages of the Mitsubishi 4G61 engine
- Since there are no balance shafts, the main problem of the series does not threaten these engines;
- Due to poor oil, hydraulic lifters quickly fail and begin to knock;
- Dirty idle control or throttle are the main causes of idle speed;
- The timing belt may not pass the 90,000 km assigned to it, and when it breaks, the valves bend;
- The pillows of the power unit serve here for a very short time, for some reason especially the left.
