1994 4.3lx rocker noise how to adjust?

There isn't a value.

remove v/covers or cover if you want to do 1 side at a time you can purchage a set of oil deflecters from your local auto parts store, they will deflect the oil that squirts out of the rocker arm and makes a mess also place a peice of caurdboard in the bottom of the head to catch the oil from the rockers,get it running tighten down anny loose rockers than start from the front loosen the rocker until ti ticks, tighten it down until it is quiet than go 3/4 to 1 turn further your done one down 11 more to go
