To take out and set up a lifter or lash adjuster, begin with the cylinder head cover, then get rid of the
Camshafts. After that, remove each camshaft tappet, repeating the same steps for all of them. If you plan to reuse the tappets, remember to mark each one for putting back in the same place. When either the cylinder head or camshafts are replaced, camshaft tappets should be changed as well and this maintenance should be done while the camshaft is securely in the engine.
