Need torque on 1997 chevy tahoe 5.7 rocker arm torque


The rocker arms need to be adjusted, they are not set to a specific torque, they use self locking "crimp" nuts to hold the adjustment, these nuts should not be used over to hold the adjustment replace them.. With the lifters fully "pumped" up tighten the rocker arms to "zero" lash, the turn them in an additional 3/4 turn, you are done.

How do I adjust the valves on a 1998 old bravada 4.3 vortec


You don't. They are non-adjustable hydraulic lifters. GM's spec for torque on the rocker arm nuts: Tighten the valve rocker arm ball studs to 47 N·m (35 lb ft). Once the valve rocker arm nuts are installed and properly torqued, no additional valve lash adjustment is required.
