Disadvantages of the Honda F20A engine
- The most famous problem of these units is oil burn after 100,000 km;
- In second place in popularity are frequent oil and coolant leaks;
- The timing belt serves approximately 90,000 km, and when it breaks, the valve most often bends;
- The motor can often start to blunt due to the failure of the distributor or one of the sensors;
- There are no hydraulic lifters and valve clearances need to be adjusted every 40,000 km.
