3.8L Engine
1. Disconnect the negative battery cable. Disconnect the secondary ignition wires at
the spark plugs.
2. Remove the plug wire routing clips from mounting studs on the rocker arm cover
attaching bolts. Lay plug wires with routing clips toward the front of engine.
3. Remove the upper intake manifold, rocker arm covers and lower intake manifold.
4. Sufficiently loosen each rocker arm fulcrum attaching bolt to allow the rocker arm
to be lifted off the pushrod and rotated to one side.
5. Remove the pushrods. The location of each pushrod should be identified and
labeled. When engine is assembled, each rod should be installed in its original
position.
6. If equipped with roller lifters, remove the 2 tappet guide plate retainers and 6 guide
plates.
7. Remove the lifters using a magnet. The location of each lifters should be identified
and labeled. When engine is assembled, each lifter should be installed in its
original position.
If lifters are stuck in bores due to excessive varnish or gum deposits, it
may be necessary to use a hydraulic lifter puller tool to aid removal.
When using a remover tool, rotate lifter back and forth to loosen it from
gum or varnish that may have formed on the lifter.
To install:
8. Lightly oil all bolt and stud threads before installation. Using solvent, clean the
cylinder head and valve rocker arm cover sealing surfaces.
9. Lubricate each lifter and bore with oil conditioner or heavy engine oil.
10. Install each lifter in bore from which it was removed. If a new tappet(s) is being
installed, check new lifter for a free fit in bore.
11. If equipped with roller lifters, align the flats on the sides of the lifters and install
the 6 guide plates between the adjacent lifters. Make sure the word "up'' and/or
button is showing. Install the 3 guide plate retainers and tighten the 4 bolts to 6-10
ft. lbs. (8-14 Nm).
12. Dip each pushrod end in oil conditioner or heavy engine oil. Install pushrods in
their original positions.
13. For each valve, rotate crankshaft until lifter rests onto heel (base circle) of
camshaft lobe. Position rocker arms over pushrods and install the fulcrums.
Initially tighten the fulcrum attaching bolts to 44 inch lbs. (5 Nm) maximum.
14. Lubricate all rocker arm assemblies with suitable heavy engine oil.
15. Finally tighten the fulcrum bolts to 19-25 ft. lbs. (26-34 Nm). For the final
tightening, the camshaft may be in any position.
Fulcrums must be fully seated in the cylinder head and pushrods must be
seated in rocker arm sockets prior to the final tightening.
16. Complete the installation of the lower intake manifold, valve rocker arm covers and
the upper intake manifold by reversing the removal procedure.
17. Install the plug wire routing clips and connect wires to the spark plugs.
