  Q: How to replace the LH Lash Adjuster on Cadillac STS?

  A: For substitution of the left Lash Adjuster, you need to remove the left valve Rocker Arms such that each camshaft follower is still matched with the original stationary hydraulic Lash Adjuster (SHLA) and location. Then, uncover the shla from the left cylinder heads bores, clean and check the lash adjusters. Check the Crankshaft position to top dead centre (TDC) of the number one cylinder before installation. Fill the shla with fresh engine oil (GM P/N 12378006 or equivalent), watching that the pivot sphere area of the shla is not to be scratched. Lubricate the shla bores of the cylinder head with clean engine oil (GM P/N 12378006 or equivalent) using a lint-free cloth, then press inward on the shla to install the shla to the bores, then all there left valve rocker arms.
