  1. CONSTRUCTION


    1. A valve lash adjuster assembly is located at the fulcrum of each No. 1 valve rocker arm sub-assembly. A valve lash adjuster assembly consists primarily of a plunger, a plunger spring, a check ball, and a check ball spring.

    2. The valve lash adjuster assembly is actuated by the engine oil, plunger spring, and check ball spring. The oil pressure and the spring force that act on the plunger push the No. 1 valve rocker arm sub-assembly against the cam, in order to adjust the valve clearance. This reduces the engine noise that is created during the opening and closing of the valve.

      Tech Tips

      Valve clearance adjustment is not necessary because valve lash adjuster assemblies are used.
