• Q: How to service and repair the rocker arm assembly on 2008 Buick Lucerne?

  A: To repair or service the Rocker Arm assembly use the torque angle meter (J 45059) as your necessary tool. Start by discarding the valve Rocker Arm covers from the engine then detach the valve Rocker Arm bolts which you should place on a clean area for storage before reinstallation. Begin by removing the valve Rocker Arm(s) then the valve Rocker Arm guide plate because all rocker arms are being replaced and the push rod(s) come next. Vacate the push rods together with valve rocker arms and bolts and guide plates from suitable solutions while verifying that thread adhesive does not exist on valve Rocker Arm bolts. Position all the push rods correctly after spraying prelube onto their ends. Before installation, use compressed air to remove oil from the Cylinder Head tapped holes. Secure the valve Rocker Arm guide plates and valve rocker arms after treating the Rocker Arm bolt threads with threadlock material. Torque the Rocker Arm bolts to a value of 15 n.m (11 lb ft) while simultaneously turning them by 90 degrees additional degrees when measuring with the torque angle meter (J 45059). Complete the installation by installing the valve Rocker Arm cover(s) then perform a noise check on the valve train system.
