Disadvantages of the Mitsubishi 4A92 engine
- Most often, owners complain about the oil burner due to the wear of rings or caps;
- Oil starvation greatly reduces the resource of the connecting rod and piston group of the motor;
- Some components of the ignition system have low reliability here;
- After 100 thousand km, there are leaks of the crankshaft oil seal and stretching of the timing chain;
- Hydraulic compensators are not provided and valve clearances have to be adjusted.
how often valve clearances need to be adjusted ?
Standard value:
Intake valve 0.22 ± 0.04 mm
Exhaust valve 0.30 ± 0.04 mm
It is recommended to check the clearances at a run of 100,000 km and then every 50,000 km. Adjust valve clearances if they deviate from the above values.
