  Q: How to replace the valve rocker arm and push rods on Buick Terraza?

  A: The initial step before valve Rocker Arm and push rod replacement starts with removing valve Rocker Arm covers followed by segregating all components to maintain correct later installation. You should begin by removing the Rocker Arm bolts before extracting the rocker arms as well as the Pushrods. Start by repositioning the pushrods to their installation locations and ensure the ends receive application of gm p/n 1052356 chemical or its substitute material. The intake pushrods have yellow stripes for marking and measure 5 3/4 inches while exhaust pushrods with green stripes measure 6 inches in length and need to properly seat in the lifter. Next install the rocker arms before affixing Rocker Arm bolts at 32 nm (24 ft. Lbs.) while replacing valve rocker covers.
