2002 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to service and repair the rocker arm assembly on 2002 Buick Park Avenue?

  A: Service and repair operations on the rocker arm assembly start with removing left and right valve rocker arm covers after which you must remove the pedestal retaining bolts and pedestal from the assembly setup components on a clean surface for future reinstallation. You should then separate the rocker arm assembly with pushrods while cleaning all thread adhesive from bolts before examining valve rocker arms and pushrods. Installation requires first mounting the pushrods and valve rocker arm assembly after which the pedestal needs to be placed. The threads of the valve rocker arm bolt require GM P/N 12345493 (Canadian P/N 10953488) threadlocker compound or equivalent before installing the pedestal retaining bolts. Use the Torque Angle Meter (J 36660-A) to tighten all valve rocker arm bolts to 15 Nm (11 ft. lbs.) + 90 degrees. The last step involves reinstalling left and right valve rocker arm covers while testing for any valve train noises.
