Disadvantages of the Mazda B3-ME engine

- If you have a version with hydraulic lifters, do not save on oil or they will rattle;
- The weak points of the engine also include the oil pump pressure reducing valve;
- The timing belt resource is on average 60,000 km, but when it breaks, the valves do not bend;
- On a run of over 200,000 km, an oil burn of up to 1 liter per 1000 km is often found.
