CONSTRUCTION
The valve lash adjuster assembly, which is located at the fulcrum of the valve rocker arm sub-assembly, consists primarily of a plunger, a plunger spring, a check ball and a check ball spring.
Engine oil supplied by the cylinder head sub-assembly and the built-in spring actuates the valve lash adjuster assembly. The oil pressure and the spring force that act on the plunger push the valve rocker arm sub-assembly against the cam, adjusting the valve clearance created during the opening and closing of the valve. As a result, engine noise has been reduced.
