2008 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the pushrod and valve rocker arm on 2008 Buick Lucerne?

  A: The replacement of valve Rocker Arm and push rod begins with taking out all valve Rocker Arm covers. Start by taking out all valve Rocker Arm bolts yet maintain the parts on a clean surface and follow proper storage for reassembly. Start replacement by taking out the valve Rocker Arm guide plate when replacing all rocker arms and then extract all valve Rocker Arm(s) before removing push rod(s). A suitable solution should be used to clean the push rods along with valve rocker arms and bolts and guide plates while the valve Rocker Arm bolts must be free from thread adhesive. First remove oil accumulation from the Cylinder Head tapped holes using compressed air then apply prelube to the ends of push rods before placing them in their original positions. Mount the valve Rocker Arm guide plate(s) and valve Rocker Arm(s) where threadlock goes on the Rocker Arm bolt threads. Screw in the rockers and torque them to 15 n.m (11 lb ft) with an additional 90 degrees tightening stage while using the torque angle meter (J 45059). Check valve train noise while the valve Rocker Arm covers and all their components are in place.
