Disadvantages of the Mazda KL-DE engine
The engines in this series are reliable;
This aluminum block is terrified of overheating, so keep an eye on the cooling system;
After 100,000 kilometers, valve cover gaskets frequently become loose and leak;
Hydraulic lifters can knock up to 50,000 kilometers due to inadequate lubrication; the timing belt serves about 80–90 thousand kilometers, but when it breaks, the valve does not bend.
