Disadvantages of the Mazda LF17 engine
- In the engines of the first years, the intake manifold flaps often stuck and even fell out;
- Throttle or EGR contamination is the main cause of floating rpm;
- The thermostat, pump and engine mounts do not have the highest resource here;
- After 200-250 thousand km, an oil burner and timing chain stretch are very common;
- There are no hydraulic lifters here, so you need to adjust the valves every 100,000 km.
