Disadvantages of the Mazda F8 1.8l engine
Сarburetor modifications that are not properly tuned use a lot of fuel;
Although injector-equipped models are more dependable, the ignition system is the primary source of issues;
Because of the presence of piston rings, an oil burner is frequently discovered on extended runs;
The valves do not bend here when the timing belt breaks, even though it travels an average of roughly 60,000 km;
Hydraulic lifters can travel up to 50,000 kilometers and are not tolerant of cheap oil.
