Disadvantages of the Mazda LFF7 engine
Intake manifold flaps that are permanently stuck can cause a lot of issues;
Engine speed frequently floats here due to throttle or EGR valve contamination;
The thermostat, pump, lambda probe, and unit supports all have limited resources.
Oil consumption frequently emerges or the chain is stretched after 200,000 kilometers of operation;
Every 100,000 kilometers, valve clearances must be adjusted because there are no hydraulic lifters.
