Disadvantages of the Mazda KF-ZE engine

  • The motors of this series are considered reliable, but the aluminum block is afraid of overheating;
  • Owners often complain about oil consumption, sometimes it reaches a liter per 1000 km;
  • At high mileage, lubricant can also ooze from under the valve covers here;
  • The timing belt lasts about 80,000 km, but when it breaks, the valves usually do not bend;
  • From cheap lubrication, hydraulic lifters can fail already by 50 – 70 thousand km.

1 thought on “Engine Mazda KF-ZE”

  1. My Mazda MX6 is fitted with the 2 litre KFZE engine. It has been raced in virtually stock condition from 257000 km to 283000 km and still running strong. The key is regular oil changes for reliability.
