  Q: How to replace the pushrod and valve rocker arm on GMC Sierra 1500 Classic?

  A: Mark all components first as part of the process to replace the valve Rocker Arm and push rod and then organize them for assembly. The first step requires removing the Rocker Arm cover before taking out all the rocker arms together with their supports and pushrods. The rocker arms plus pushrods require inspection for cleanliness while inspection can proceed as needed. Installation requires maintaining part order which leads to proper reinstallation at original positions. Mount the pushrods onto the vehicle yet keep the arrow point on each Rocker Arm support in its raised position until setting the Rocker Arm supports. Use the specified item number from sealers, adhesives, and lubricants to apply lubricant on the Pushrod socket and roller pivot and valve stem tip. Begin by using fingers to start bolts at locations , , and before proceeding with the remainder of the Rocker Arm bolts. Set the crankshaft balancer to align its mark at 57-63 degrees either clockwise or counterclockwise away from the engine front cover tab. The rocker arms require no further adjustment of valve lash because they need proper torque during installation. Systematically tighten all Rocker Arm bolts to 30 nm (22 ft. Lbs.) after you install the Rocker Arm cover.
