Disadvantages of the Honda F23A engine

- In second place are complaints about regular oil and coolant leaks.
- The cause of tripping and floating engine speeds is usually a dirty idle valve and EGR.
- The timing belt serves approximately 90,000 km and if you miss a replacement, it will bend the valves.
- Due to the lack of hydraulic lifters, the valves need to be adjusted every 40,000 km.
