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.
Can you convert the carburettor one to fuel injection or have to replace complete engine
