Disadvantages of the X16XEL engine

- Oil consumption begins, and in the service station they offer useless decarbonization in this case;
- Monitor the condition of the timing belt, it has a resource of 60,000 km, and when it breaks, the valves bend;
- The cause of floating speed or dips in engine thrust is contamination of the EGR valve;
- Common breakdowns include drying gaskets under the nozzles.
