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.
To install: 4. Coat the bearings surf aces with a thin coating of Molykote® or its
equivalent.
5. Install the pushrods and make sure the rod is in the lifter seat.

6. Install the rocker arm, balls and
nut. Tighten the nut until all lash is
eliminated.
7. The engine must be on the No. 1 fi ring position before proceeding. This
may be determined by placing your fi ngers on the No. 1 rocker arms as
the mark crankshaft damper is rotat ed towards the "0" on the timing tab.
If the arms did not move, it is in the No. 1 firing position. If they did move,
turn the crankshaft one full revoluti on to reach the No. 1 position.
Remember, the mark on the crankshaft balancer must be aligned with
the "0" on the timing tab.
8. Adjust the valves as follows:
V6 ENGINES
With the engine on the number 1 firing pos ition, exhaust valves 1, 2 and 3 and
intake valves 1, 5 and 6
may be adjusted. Back out t he adjusting nut until lash is felt at the pushrod.
Tighten the adjusting nut unt il all lash is removed, then tighten the nut an
additional 1
1/2 turns to center the lifter plun ger. Turn the engine one revolution
until the "0" timing mark is once again al igned. Exhaust valves 4, 5 and 6 and
intake valves 2, 3 and 4 may be adjusted.
V8 ENGINES
With the engine on the number 1 firing posit ion, exhaust valves 1, 3, 4 and 8,
intake valves 1, 2, 5 and 7 may be adj usted. Back out the adjusting nut until
lash is felt at the pushrod. Tighten the adjusting nut until all lash is removed,
then tighten an additional 1 turn to center the lifter plunger. Turn the engine one
revolution until the 0 timing mark is once again aligned. Exhaust valves 2, 5, 6
and 7, intake valves 3, 4, 6 and 8 may be adjusted.
9. Install the rocker arm cover.
2.5L ENGINE 1. Disconnect the negative battery cable.
2. Remove the valve cover.

FUEL INJECTION

1. Remove the air cleaner.
2. Drain the radiator.
3. Disconnect: a. Battery cables at the battery.
b. Upper radiator and heater hoses at the manifold.
c. Crankcase ventilation hoses as required.
d. Fuel line at the carburetor.
e. Accelerator linkage.
f. Vacuum hose at the distributor, if equipped.
g. Power brake hose at the car buretor base or manifold, if
applicable.
h. Temperature sending switch wires.
4. Remove the distributor cap and scribe the rotor position relative to the
distributor body, and engine.
5. Remove the distributor.
6. If applicable, remove the alternator upper bracket. As required, remove
the air cleaner bracket, and accelerator bellcrank.
7. Remove the manifold-to-head attachi ng bolts, then remove the manifold
and carburetor as an assembly.
8. Mark and disconnect all emission re lated items (e.g.: wiring, vacuum
hoses, etc.) which are connected to manifold mounted items.

studs), water outlet and thermostat (use a new gasket) heater hose
adapter, EGR valve (use new gasket) and, if applicable, TVS switch(s)
and the choke coil.
To install: 10. Before installing the manifold, thoroughly clean the gasket and sealing
surfaces of the cylinder heads and manifold.
11. Install the manifold end seals, folding the tabs if applicable, and the
manifold/head gaskets, using a s ealing compound around the water
passages.

12. When installing the manifold, care should be taken not to dislocate the
end seals. It is helpful to use a pilo t in the distributor opening. Tighten the
manifold bolts to 30 ft. lbs. (40 Nm) for 5.0L or 20-25 ft. lbs. (27-34 Nm)
for 2.8L in the sequence illustrated.
13. Install the distributor with the rotor in its original location as indicated by
