Disadvantages of the Mazda F8 1.8l engine

  • Modifications with a carburetor without proper tuning consume a lot of fuel;
  • Versions with an injector are more reliable, the main problems are related to the ignition system;
  • On long runs, an oil burner is often found due to the occurrence of piston rings;
  • The timing belt runs an average of about 60,000 km, but when it breaks, the valves do not bend here;
  • Hydraulic lifters do not tolerate cheap oil and can knock even up to 50 thousand km.
