Disadvantages of the Mazda KF-DE engine

  • The aluminum block here is very afraid of overheating, keep an eye on the cooling system;
  • After 100-150 thousand run, these power units often already consume oil;
  • Approximately at the same runs, there are lubricant leaks from under the valve covers;
  • The timing belt changes every 80,000 km, but when it breaks, the valves almost never bend;
  • From low-quality oil, hydraulic lifters can knock even up to 50 thousand km.
