Disadvantages of the Mazda B5-ME engine
- Based on the activity on the specialized forums, the ignition system delivers the most problems.
- On versions of engines with hydraulic compensators, they can easily be damaged by low-quality oil.
- Another weak point of the motor is the oil pump pressure relief valve.
- According to the regulations, the timing belt changes every 60,000 km, but when it breaks, the valves do not bend.
- Closer to 200 thousand km, oil scraper rings may lie down and lubricant consumption will appear.
