2002 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the Lash Adjusters on 2002 Buick Park Avenue?

  A: Start by arranging valve train components properly since they need to go back to their original positions during the replacement process. Rocker Arm removal starts the process which continues with pushing out both pushrods and pedestals before you can move to lower Intake Manifold and gaskets. You should remove the valve guide retainer bolts before extracting both components from the valve guide retainer and valve lifters. Afterward you can remove valve lifters guides and valve lifters. Before submerging new valve lifters in prelube gm p/n 12345501 (Canadian P/N 992704) or an equivalent the valve lifters and guides should be inspected and cleaned separately. The installation process starts with valve lifters before adding valve lifter guides followed by valve guide retainers. Fasten the valve guide retainer bolts to a torque specification of 30 nm (22 ft. Lbs.). After this, reinstall all components of the lower Intake Manifold along with new gaskets, followed by replacement of the valve rocker arms and pushrods and pedestals.
