GM Camaro 1967-1981 Repair Guide

Hydraulic Lifters


If the rocker arm retaining nut was loosened or removed for rocker arm or pushrod removal, valve lash for the hydraulic valve lifters must be set. Initial valve lash adjustment is covered in Engine And Engine Overhaul under the Rocker Arm Removal & Installation procedures.

All Camaros, with the exception of those few already discussed, use a hydraulic tappet system with adjustable rocker mounting nuts to obtain zero lash. No periodic adjustment is necessary.
