Disadvantages of the Honda F20A engine
Oil burn after 100,000 kilometers is the most well-known issue with these units;
Frequent coolant and oil leaks rank second in popularity;
The valve typically bends when the timing belt breaks, which lasts for about 90,000 kilometers;
When the distributor or one of the sensors fails, the motor can frequently begin to blunt;
Every 40,000 kilometers, valve clearances must be changed because there are no hydraulic lifters.
