How to replace the Lash Adjusters on the left side on 2007 Cadillac DTS?

Start by detaching the left valve rocker arms from their bores while removing the stationary hydraulic lash adjusters (LAs). The lash adjusters should undergo both cleaning and inspection operations. The installation process mandates avoiding exposure of the la plunger to oil-free lower pressure chamber cycles before addition. Insert clean engine oil into the la while paying attention to avoid damaging the la's pivot sphere area. Last step is to slide new la units into their bores followed by a replacement of the left valve rocker arms.
