To service and repair the Lash Adjuster on the right side, first serving, take off the right camshafts. Then, extract the lash adjusters from the bores using a magnet and arrange them in a rack in a sequential way to ensure that they can be reinstalled in their original sequence in case they wish to be reused before the end of their useful life. For installation, lubricate the lash adjusters using prelube (GM P/N United States 1052367, GM P/N Canada 992869 or equiv.) if they are reinstalling in their original position not being replaced. Finally, reinstall the right camshafts.
