Q: How to Service and Repair a Rocker Arm Assembly on 2008 Dodge Challenger?
A: To service the rocker arm assembly, remove the cylinder head cover and install Pushrod Retainer 9070. Loosen rocker shafts in order, remembering that intake and exhaust assemblies are not interchangeable. Remove the rocker shafts and pushrods, keeping track of their locations. For this reason, don't remove retainers as they can be damaged.
