DeVille DTS V8-4.6L VIN 9 (2002)
1. Apply a liberal amount of lubricant GM P/N 12345001 or equivalent to the roller pivot pocket (2) and valve slot areas (1) of the camshaft
followers.
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.
2. Place the camshaft followers in position on the valve tip and the Stationary Hydraulic Lash Adjusters (SHLA) (1). The rounded head of the
follower goes on the SHLA, while the flat end goes on the valve tip.
3. Clean the camshaft carriers with a clean, lint-free cloth.
4. Apply a liberal amount of lubricant GM P/N 12345001 or equivalent to the camshaft carriers, camshaft lobes (1) and the camshaft journals (2).
5. Place the camshaft in the camshaft carriers with the camshaft sprocket drive pins near the top of their rotation and the camshaft lobes in a neutral
position. The camshafts can be identified by a stamping near the rear journal. For example: L-EXH is defined as Left bank Exhaust.
