Disadvantages of the Mazda KL-G4 engine
Although this motor is very dependable, the cylinder head and aluminum block are terrified of overheating;
Replace the candles as soon as possible to avoid having to replace three costly coils.
Grease leaks from beneath the valve covers may occur after 100,000 kilometers;
Since there are no hydraulic lifters here, the valves must be adjusted every 100,000 kilometers. The belt runs 80,000 kilometers, and replacing it is challenging and costly. If the belt breaks, the valve does not bend.
