Disadvantages of the Mazda K8-ZE engine
- The cylinder block and cylinder head are cast from aluminum and are very afraid of overheating;
- Also, power units of this series often consume oil after 150 thousand km;
- On the same run, there are often leaks of lubricant from under the valve covers;
- The timing belt changes every 100,000 km, however, when it breaks, the valves usually do not bend;
- Hydraulic lifters do not tolerate cheap oil and can knock even up to 50,000 km.
