Valve lifter noise ranges from light noise to a
heavy click. A light noise is usually caused by exces-
sive leak-down around the unit plunger which will
necessitate replacing the lifter, or by the plunger par-
tially sticking in the lifter body cylinder. A heavy
click is caused either by a lifter check valve not seat-
ing, or by foreign particles becoming wedged between
the plunger and the lifter body causing the plunger
to stick in the down position. This heavy click will be
accompanied by excessive clearance between the
valve stem and rocker arm as valve closes. In either
case, lifter assembly should be removed for inspec-
tion.
REMOVAL
(1) Remove the cylinder head(s). (Refer to 9 -
ENGINE/CYLINDER HEAD - REMOVAL)
(2) Remove the yoke retainer and aligning yokes
(Fig. 47).
(3) Remove the hydraulic lifters. If necessary use
Special Tool C-4129, or equivalent to remove lifters
from bores. If lifters are to be reused, identify each
lifter to ensure installation in original location.
INSTALLATION
(1) Lubricate the lifters with engine oil.
NOTE: Position the lifter in bore with the lubrication
hole facing upward (Fig. 46).
(2) Install the hydraulic lifters with the lubrication
hole facing upward towards middle of block (Fig. 46).
Install lifters in original positions, if reused.(3) Install lifter aligning yokes (Fig. 47).
(4) Install yoke retainer and torque screws to 12
N´m (105 in. lbs.) (Fig. 47).
(5) Install the cylinder heads. (Refer to 9 -
ENGINE/CYLINDER HEAD - INSTALLATION)
(6) Start and operate engine. Warm up to normal
operating temperature.
CAUTION: To prevent damage to valve mechanism,
engine must not be run above fast idle until all
hydraulic lifters have filled with oil and have
become quiet.

LUBRICATION
DESCRIPTION
The lubrication system is a full flow filtration pres-
sure feed type. The oil pump is mounted in the tim-
ing chain cover and is driven by the crankshaft
OPERATION
Oil from the oil pan is pumped by a internal gear
type oil pump directly coupled to the crankshaft. The
pressure is regulated by a relief valve located in the
timing chain cover. The oil is pumped through an oil
filter and feeds a main oil gallery. This oil gallery
feeds oil under pressure to the main and rod bear-
ings, camshaft bearings. Passages in the cylinder
block feed oil to the hydraulic lifters and rocker shaft
brackets which feeds the rocker arm pivots (Fig. 94).
DIAGNOSIS AND TESTING - ENGINE OIL
PRESSURE
(1) Disconnect and remove oil pressure switch
(Refer to 9 - ENGINE/LUBRICATION/OIL PRES-
SURE SENSOR/SWITCH - REMOVAL).
(2) Install Special Tools C-3292 Gauge with 8406
Adaptor. For Special Tool identification, (Refer to 9 -
ENGINE - SPECIAL TOOLS).
(3) Start engine and record oil pressure. Refer to
Oil Pressure in Engine Specifications for the correct
pressure (Refer to 9 - ENGINE - SPECIFICATIONS).

(2) Install rocker arms and shaft to the cylinder
head. (Refer to 9 - ENGINE/CYLINDER HEAD/
ROCKER ARMS - INSTALLATION)
INSTALLATION - ROCKER ARMS AND SHAFT
CAUTION: Ensure the longer shaft retaining bolt is
installed in the proper location on the rocker shaft.
(Refer to 9 - ENGINE/CYLINDER HEAD/ROCKER
ARMS - ASSEMBLY)
(1) Position the rocker arm and shaft assemblies
on the pedestal mounts.
CAUTION: Ensure all pushrods are properly located
on the lifter and the rocker arm socket.
(2) Align each rocker arm socket with each push-
rod end.
CAUTION: The rocker arm shaft should be tight-
ened down slowly, starting with the center bolts.
Allow 20 minutes lifter bleed down time after instal-
lation of the rocker shafts before engine operation.(3) Slowly tighten rocker shaft bolts evenly until
shaft is seated. Tighten bolts to 23 N´m (200 in. lbs.)
(Fig. 27).
(4) Install the cylinder head cover(s). (Refer to 9 -
