Disadvantages of the Mazda WE-C engine
- The Bosch Common Rail system is reliable but very sensitive to diesel quality;
- The variable-geometry turbocharger and the intake flaps do not tolerate soot;
- The cylinder head does not tolerate overheating, and a new one is expensive;
- Watch the timing belt: if it breaks, it destroys the rocker arms;
- There are no hydraulic lifters, so the valve clearances need adjusting every 100,000 km.
