2003 Buick Rendezvous Lash Adjuster Parts and Q&A

• Q: How to replace the Lash Adjuster on 2003 Buick Rendezvous?

  A: One must begin the valve lifter replacement procedure by taking out the engine left side valve Rocker Arm cover before moving on to the engine right side valve Rocker Arm cover along with the upper Intake Manifold and lower Intake Manifold. Begin by removing the valve rocker arms and pushrods followed by the oil splash shield and the lifter guide bolts and lifter guide. The placement of valve train parts within a rack will help identify their correct installation order. Clean the removed lifter(s) before performing visual inspections. To update the installation you need to return the lifters to original removal positions before installing both the lifters and the lifter guide and subsequently the valve rocker arms and pushrods. Installation requires a sequence of reinserting the lower Intake Manifold and upper Intake Manifold and then the engine right side valve Rocker Arm cover and engine left side valve Rocker Arm cover.
