2004 Buick Rendezvous Rocker Arm

You can remove the valve rocker arm cover, remove the valve rocker arm bolt, remove the valve rocker arm, remove the Pushrod and clean and inspect the valve train components.

You need to remove the right engine strut mount, the thermostat bypass pipe, and remove the PCV valve from the valve rocker arm cover, remove the valve rocker arm cover bolts, remove the valve rocker arm cover, then trim Valve Cover gasket and sealant away from lower intake manifold gasket at the cylinder head to lower intake manifold joints, remove the valve cover gasket, and clean the sealing surface on the cylinder head with degreaser, lastly clean the valve rocker arm cover.

The proper way is to install the lifters and the lifter guide, the valve rocker arms and pushrods, the lower and upper intake manifold, the engine right side valve rocker arm cover, and the engine left side valve rocker arm cover.
