Disadvantages of the Mazda KF-ZE engine
- The motors of this series are considered reliable, but the aluminum block is afraid of overheating;
- Owners often complain about oil consumption, sometimes it reaches a liter per 1000 km;
- At high mileage, lubricant can also ooze from under the valve covers here;
- The timing belt lasts about 80,000 km, but when it breaks, the valves usually do not bend;
- From cheap lubrication, hydraulic lifters can fail already by 50 – 70 thousand km.
