2008 Chevrolet Impala Rocker Arm Parts Questions & Experts Answers

• Q: How to replace the valve rocker arm and push rods on 2008 Chevrolet Impala?

  A: The initial step for valve Rocker Arm and push rod replacement involves setting valve train parts into a rack for ordered arrangement. Remove the valve Rocker Arm cover(s) from the engine at the beginning of the repair process. Begin by loosening the valve Rocker Arm bolts then removing the rocker arms after which proceeds to the pushrods while recognizing that the intake push rods reach a length of 147.51 mm (5.81 in) and exhaust push rods reach a length of 154.87 mm (6.1 in). After applying prelube to Pushrod ends users should install them while confirming that yellow-striped intake pushrods seat correctly in the lifter bore alongside blue-striped exhaust pushrods. The installation process requires prelube coating on Rocker Arm friction surfaces together with the possible need of shims (88894006) under valve Rocker Arm pedestals in case of Cylinder Head or component reconditioning. After installing the rocker arms the next step requires mounting the bolts before tightening them to 34 n.m (25 lb ft). The installation sequence concludes with the replacement of needed valve Rocker Arm covers.
