First, take out the cylinder head cover, then the
Timing Belt, sprockets and covers. When all those are removed, take away the
Camshaft to get access to the rocker arm assembly. It's necessary to mark the location of cam follower assemblies so they can be put back together correctly. After that, take out the cam follower assemblies from the cylinder head and check them for damage. Replace them if required. Once the cam follower assemblies are oiled, put them back in their original location on the hydraulic adjuster/valve stem. When that is finished, reinstall the camshafts, timing belt, sprockets and covers and lastly, secure the cylinder head cover.
