Disadvantages of the X16XEL engine
- The main problem is valve stem seals flying off the valve guides;
- 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.
Are the exhaust and inlet cams for this engine the same?
If I have them swopped around what would happen to the performance of the car?
How do you tell which cam is which when looking at them? They have the same number on them.
Also what is the purpose of the AIR INJECTION FAN that connects to the exhaust manifold top?
Thanks.
