Disadvantages of the Mazda KL-G4 engine
- This motor is quite reliable, but the aluminum block and cylinder head are very afraid of overheating;
- Do not delay with the replacement of candles or you will have to change 3 expensive coils;
- After 100 thousand km, you may encounter grease leaks from under the valve covers;
- The belt runs 80,000 km, replacement is difficult and expensive, but if the belt breaks, the valve does not bend;
- Since there are no hydraulic lifters here, the valves need to be adjusted every 100,000 km.
