Disadvantages of the Mazda ZY-VE engine
The unit’s propensity for accelerated carbon formation is its primary issue.
The engine will start to noticeably lose power by 100,000 kilometers if decarbonization is not done on a regular basis.
Floating speeds are primarily caused by EGR and throttle pollution.
Although the replacement is costly, the timing chain has a good resource.
Every 100,000 kilometers, the valve clearance is adjusted; hydraulic lifters are not used.
