Disadvantages of the Mazda B6-ME engine
Only at high mileage does a structurally straightforward and dependable motor cause concern; ignition system failures are most frequently discussed on specialized forums;
The timing belt resource is about 60,000 km, but when it breaks, the valves typically do not bend; after 150–200 thousand km, hydraulic lifters frequently knock and oil burn starts; idle speeds frequently float here, primarily because of throttle contamination.
