I have a 2002 Jeep Cherokee 2.5 CRD limited (SWB).The cambelt broke,but according to Jeep it does not damage the valves only the rockers,but not one rocker broke!.Is this possible?.Thanks Gerard

Most auto parts stores with decode for you , for free.

its on the fuel tree that goes to each cylinder.. it has a plastic screw on cover and under that is a shcrader valve similar to the valve in a tire stem..push in on this while the pump, is on.. wait for all the trapped air to come out..replace the cap and start the vehicle..

I think this is it

well it could be the idle control valve or vacuum leak check all vacuum lines for cracks and listen for air sound you may need to check PVC valve

see if advanced auto, or autozone carrys it

Remove the valve covers. Inspect each rocker arm for wear, cracks or other damage, check the rocker arm abd dykcrum for wear, replace with new ones, they can"t be adjusted.
