Rocker Arm Cleaning and Inspection

WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean all parts thoroughly. Make sure all oil passages are open.
  2. Make sure the oil passage in the push rod/valve tappet end of the rocker arm is open.
    CAUTION: Do not attempt to true surfaces by grinding. Check the rocker arm pad, side rails and seat for excessive wear, cracks, nicks or burrs. Check the rocker arm seat bolt for stripped or broken threads. Install new components as necessary or engine damage may occur.
  3. Inspect the rocker arm push rod bore for nicks, scratches, scores or scuffs.
