Disadvantages of the Mazda B6-DE engine
Although this engine is regarded as dependable, it frequently runs out of oil after 150,000 kilometers.
Additionally, hydraulic compensators in this area rapidly fail due to inadequate lubrication.
The oil pump pressure relief valve is another one of the motor’s weak points.
The timing belt is required to change every 60,000 kilometers, but the valves do not bend when it breaks.
The ignition system is typically linked to the power unit’s remaining issues.
