Installation Procedure

WARNING: This page is about a different car, the 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
  1. Apply a liberal amount of clean engine oil to the roller (2), lash adjuster and valve tip areas (1) of the camshaft followers.

  2. Place the camshaft followers in position on the valve tip and lifter. The rounded head end of the follower goes on the lash adjuster while the flat end goes on the valve tip.

    Important:  The follower must be positioned squarely on the valve tip so that the full width of the roller will completely contact the camshaft lobe. If the followers are being reused you must put them back in their original location.

  3. Clean the camshaft journals and carriers with a clean, lint-free cloth.
  4. Install the left (front) camshafts. Refer to Camshaft Cover Replacement - Left .
