2005 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the pushrod and valve rocker arm on 2005 Buick Park Avenue?

  A: You need to acquire the torque angle meter (J 36660-A) together with other replacement tools before beginning the work. Start by eliminating the left and right valve Rocker Arm covers then proceed to remove the pedestal retaining bolts followed by the pedestal removal. The assemblies need to sit on a clean surface until reassembly and should be placed in order on that surface. The next step involves removing the Rocker Arm assembly combined with the pushrods before cleaning all thread adhesive from the bolts and conducting a thorough inspection of the valve rocker arms as well as pushrods. First install pushrods followed by valve Rocker Arm assembly before installing the pedestal. Access to the two bolts that connect the lower Intake Manifold to the Cylinder Head becomes possible after the upper Intake Manifold has been removed. The installation of the valve Rocker Arm pedestal retaining bolts requires gm p/n 12345493 (Canadian P/N 10953488) threadlocker compound or any equivalent product as the first step before bolt installation. The torque angle meter (J 36660-A) should be used to apply torque of 15 nm (11 ft. Lbs.) while also achieving a 90 degree angle to the bolts. Before continuing with the job reinstall the left and right valve Rocker Arm covers while verifying no valve train noise occurs.
