  Q: How to replace the Lash Adjusters on Chevrolet Silverado 1500 Classic?

  A: Begin valve lifter replacement by removing the Intake Manifold along with pushrods before placing all components in a rack for correct reinstallation. After removing valves' lifter pushrod guide bolts you need to position valve lifters vertically in the rack to retain their oil content before lifting them out. When lifters get stuck because of gum or varnish buildup you should use the valve lifter remover (J 3049-A) tool to help them come out. Rinse the valve lifter bores with cleaning solvent then use a shop towel to clean them before inspecting for severe wear or scoring. Replace your engine block if necessary. Before finalizing check the Camshaft for damage and wear while removing it for better evaluation. After inspection, clean activated lifters if necessary. During new lifter installation add lubricant to the rollers while reinstalled lifters must remain in their initial setup. After tightening the guide bolts to 16 nm (12 ft. Lbs.) you can proceed to mount the pushrods and Intake Manifold. A new engine starts with a normal slight ticking noise during its initial startup period. The noise can be eliminated by increasing engine rpm slightly.
