DURE). Be careful not to gouge or scratch the alumi-
num head sealing surface.
Clean all engine oil passages.
INSPECTION
(1) Before cleaning, check for leaks, damage and
cracks.
(2) Clean cylinder head and oil passages.
(3) Check cylinder head for flatness (Fig. 19).
(4) Cylinder head must be flat within:
²Standard dimension = less than 0.05 mm (0.002
inch.)
²Service Limit = 0.2 mm (0.008 inch.)
²Grinding Limit = Maximum of 0.2 mm (0.008
inch.) is permitted.
CAUTION: 0.20 mm (0.008 in.) MAX is a combined
total dimension of the stock removal limit from cyl-
inder head and block top surface (Deck) together.
INSTALLATION - CYLINDER HEAD
(1) Clean all sealing surfaces of engine block and
cylinder heads. (Refer to 9 - ENGINE - STANDARD
PROCEDURE)
(2) Position new gasket(s) on engine block (Fig.
20). The left bank gasket is identified with the ªLºstamped in the exposed area of the gasket located at
front of engine (shown in (Fig. 20)). The right bank
gasket is identified with a ªRº stamped in the
exposed area of the gasket also, but is located at the
rear of the engine.
(3)The cylinder head bolts are torqued using
the torque yield method, they should be exam-
ined BEFORE reuse. If the threads are necked
down, the bolts must be replaced(Fig. 21).
(4) Necking can be checked by holding a scale or
straight edge against the threads. If all the threads
do not contact the scale the bolt should be replaced.
(5)
Tighten the cylinder head bolts 1±8 in the
sequence shown in (Fig. 22). Using the 4 step torque
turn method, tighten according to the following values:
²Step 1: Bolts1±8to61N´m(45ft.lbs.)
²Step 2: Bolts1±8to88N´m(65ft.lbs.)
²Step 3: Bolts1±8(again) to 88 N´m (65 ft. lbs.)
²Step 4: Bolts1±8turn an additional 1/4 Turn.
(Do not use a torque wrench for this step.)

CYLINDER HEAD COVER(S)
DESCRIPTION
The cylinder head covers are made of stamped
steel. The covers are sealed with steel reinforced sil-
icon rubber gaskets. The cylinder head cover uses
rubber isolators at each fastener location (Fig. 23).
NOTE: Due to the tight packaging near the cylinder
head covers, which makes spill clean-up difficult, a
spill during an engine oil change may be misinter-
preted as an oil leak. When investigating an oil leak
in the location of the cylinder head covers and
intake manifold, follow the procedure found in Oil
Leak Diagnosis (Refer to 9 - ENGINE - DIAGNOSIS
AND TESTING) for determining the source of a leak.

(11) Repeat procedure for each cylinder requiring
valve spring removal.
INSPECTION
Whenever valves have been removed for inspection,
reconditioning or replacement, valve springs should
be tested (Fig. 38).As an example;the compression
length of a spring to be tested is 38.00 mm (1.496
in.). Turn the table of Tool C-647 until surface is in
line with the 38.00 mm (1.496 in.) mark on the
threaded stud and the zero mark on the front. Place
spring over stud on the table and lift compressing
lever to set tone device. Pull on torque wrench until
ping is heard. Take reading on torque wrench at this
instant. Multiply this reading by two. This will give
the spring load at test length. Fractional measure-
ments are indicated on the table for finer adjust-
ments. Refer to Engine Specifications to obtain
specified height and allowable tensions (Refer to 9 -
ENGINE - SPECIFICATIONS). Replace any springs
that do not meet specifications.
INSTALLATION
INSTALLATION - CYLINDER HEAD OFF
(1) If removed, install a new valve stem seal (Refer
to 9 - ENGINE/CYLINDER HEAD/VALVE STEM
SEALS - INSTALLATION).
(2) Position valve spring and retainer on spring
seat.(3) Using Special Tool C-3422-D with 8464 Adapter
(Fig. 36), compress the spring only enough to install
the valve retainer locks. Install valve retainer locks.
(4) Slowly release the spring tension. Ensure the
retainer locks are seated properly.
INSTALLATION - CYLINDER HEAD ON
(1) The intake valve stem seals should be pushed
firmly and squarely over the valve guide using the
valve stem as guide.Do Not Forceseal against top
of guide. When installing the valve retainer locks,
compress the springonly enoughto install the
locks.
CAUTION: Do not pinch seal between retainer and
top of valve guide.
(2) Follow the same procedure on the remaining 5
cylinders using the firing sequence 1-2-3-4-5-6.Make
sure piston in cylinder is at TDC on the valve
spring that is being covered.
(3) Remove spark plug adapter tool.
(4) Install rocker arms and shaft assembly. (Refer
to 9 - ENGINE/CYLINDER HEAD/ROCKER ARMS -
INSTALLATION)
(5) Install cylinder head covers. (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION)
(6) Install spark plugs and connect wires.
(7) Connect negative cable to battery.

VALVE SPRINGS (Continued)

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.

CAMSHAFT & BEARINGS (IN
BLOCK)
DESCRIPTION
The nodular iron camshaft is mounted in the
engine block and supported with four steel backed
aluminum bearings (Fig. 48). A thrust plate, located
in front of the first bearing, is bolted to the block and
controls the camshaft end play (Fig. 48). To distin-
guish camshafts between the 3.3L and 3.8L engines,
a cast-in ring is located between the rear bearing
journal and rear lobe (Fig. 49). The 3.3L engine
application is as-cast only. The 3.8L engine applica-
tion the cast ring is machined off.
OPERATION
The camshaft is driven by the crankshaft through
a timing chain and sprockets. The camshaft has pre-
cisely machined (egg-shaped) lobes to provide accu-
rate valve timing and duration.
REMOVAL
(1) Remove the engine assembly from vehicle
(Refer to 9 - ENGINE - REMOVAL).
(2) Remove the cylinder heads (Refer to 9 -
ENGINE/CYLINDER HEAD - REMOVAL).
(3) Remove the timing chain and camshaft
sprocket (Refer to 9 - ENGINE/VALVE TIMING/TIM-
ING BELT/CHAIN AND SPROCKETS - REMOVAL).
(4) Remove the hydraulic lifters (Refer to 9 -
ENGINE/ENGINE BLOCK/HYDRAULIC LIFTERS
(CAM IN BLOCK) - REMOVAL). Identify each tappet
for reinstallation in original location.
(5) Remove camshaft thrust plate (Fig. 48).
(6) Install a long bolt into front of camshaft to
facilitate removal of the camshaft.
(7) Remove the camshaft (Fig. 48), being careful
not to damage cam bearings with the cam lobes.
NOTE: The camshaft bearings are serviced with the
engine block.
INSPECTION
(1) Check the cam lobes and bearing surfaces for
abnormal wear and damage (Fig. 50). Replace cam-
shaft as required.
NOTE: If camshaft is replaced due to lobe wear or
damage, always replace the lifters.
(2) Measure the lobe actual wear (unworn area -
wear zone = actual wear) (Fig. 50) and replace cam-
shaft if out of limit. Standard value is 0.0254 mm
(0.001 in.), wearlimitis 0.254 mm (0.010 in.).
INSTALLATION
(1) Lubricate camshaft lobes and camshaft bearing
journals with engine oil.
(2) Install a long bolt into the camshaft to assist in
the installation of the camshaft.
(3) Carefully install the camshaft in engine block.
(4) Install camshaft thrust plate and bolts (Fig.
48). Tighten to 12 N´m (105 in. lbs.) torque.
(5) Measure camshaft end play. (Refer to 9 -
ENGINE - SPECIFICATIONS) If not within specifi-
cations, replace thrust plate.
(6) Install the timing chain and sprockets. (Refer
to 9 - ENGINE/VALVE TIMING/TIMING BELT/
CHAIN AND SPROCKETS - INSTALLATION)
