Disadvantages of the Mazda B6-DE engine
- This engine is considered reliable, but often consumes oil after 150,000 km.
- Also, from poor-quality lubrication, hydraulic compensators quickly fail here.
- 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.
- The remaining problems of the power unit are most often associated with the ignition system.
