Be sure to keep all the components in t he exact order of removal so they may
be installed in there original location; adjust the valve lash after replacing the
rocker arms. Coat the replacement ro cker arm and ball with engine oil before
installation.
Rocker arms studs that have damaged thr eads or are loose in the cylinder
heads may be replaced by reaming the bore and installing oversize studs.
Oversizes available are 0.003 in. (0. 076mm) and 0.013 in (0.33mm). The bore
may also be tapped and screw-in studs installed. Several aftermarket
companies produce complete rocker arm st ud kits with installation tools.
The 2.5L engine use bolts instead of studs, 2.8L and 3.1L engines use threaded
studs, the 3.4L, 5.0L and 5.7L engines use press fit studs.
EXCEPT 2.5L ENGINES 1. Disconnect the negative (-) battery cable.
2. Remove the rocker arm cover as outlined in this section
3. Remove the rocker arm nuts, balls and rocker arms. Place components
in a rack so they can be reinstalled in the same location.
