Disadvantages of the Mazda KJ-ZEM engine
- Compressor failures are the main problem;
- The aluminum block is also very afraid of overheating, keep an eye on the cooling system;
- On runs over 100,000 km, the engine often consumes about 1 liter of oil per 1000 km;
- The timing belt is designed for 80,000 km, the replacement is expensive, but when it breaks, the valves do not bend;
- There are no hydraulic lifters and valve clearances need to be adjusted every 100,000 km.
