How to replace the left valve rocker arm on 2005 Cadillac STS?

You must start the left valve Rocker Arm replacement by removing left camshafts while retaining the original follower to stationary hydraulic Lash Adjuster (SHLA) position. Clear out and check every Rocker Arm within the left Cylinder Head as a next step after follower removal. The installation process requires generous application of lubricant gm p/n 12345001 or equivalent to the roller pivot pocket alongside valve slot areas on each Camshaft follower. Before placing the follower on the valve tip make sure it sits squarely with the roller covering the full surface of the Camshaft lobe and put reinstalled followers back in their original positions. Put the Camshaft followers onto the valve tips first and shlas next while placing the rounded end on the shla and the flat end on the valve tip then better install the left camshafts.
