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/

PISTON & CONNECTING ROD
DESCRIPTION
The pistons are made of cast aluminum alloy and
are a strutless, short skirt design. The piston rings
consist of two compression rings and a three piece oil
ring. Piston pins connect the piston to the forged
steel connecting rods. The piston pins are a press fit
into the connecting rod.
STANDARD PROCEDURE
STANDARD PROCEDURE - FITTING
CONNECTING RODS
The bearing caps are not interchangeable or
reversible, and should be marked at removal to
ensure correct reassembly. The bearing shells must
be installed with the tangs inserted into the
machined grooves in the rods and caps. Install cap
with the tangs on the same side as the rod. For con-
necting rod bearing fitting (Refer to 9 - ENGINE/EN-
GINE BLOCK/CONNECTING ROD BEARINGS -
STANDARD PROCEDURE). Fit all connecting rods
on one bank until complete.
NOTE: The connecting rod cap bolts should be
examined before reuse. Bolt stretch can be checked
by holding a scale or straight edge against the
threads. If all the threads do not contact the scale
the bolt must be replaced (Fig. 51).

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).

INTAKE MANIFOLD
DESCRIPTION
The intake system is made up of an upper and
lower intake manifold. The upper intake manifold is
made of a composite for both the 3.3L engine and for
the 3.8L engine (Fig. 117). The lower intake manifold
is common between the two engines (Fig. 121). It also
provides coolant crossover between cylinder heads
and houses the coolant thermostat (Fig. 121).
The intake manifold utilizes a compact design with
very low restriction and outstanding flow balance.
This design allows the engine to perform with a wide
torque curve while increasing higher rpm horse-
power.
If, for some reason, the molded-in vacuum ports
break, the composite manifold can be salvaged. The
vacuum ports are designed to break at the shoulder,
if overloaded. Additional material in the shoulder
area provides sufficient stock to repair. For more
information and procedure, (Refer to 9 - ENGINE/
MANIFOLDS/INTAKE MANIFOLD - STANDARD
PROCEDURE). Also, if the special screws that attach
the MAP sensor, power steering reservoir, throttle
cable bracket, and the EGR tube become stripped, an
oversized screw is available to repair the stripped-out
condition. For more information and procedure,

VALVE TIMING
STANDARD PROCEDURE
STANDARD PROCEDURE - VALVE TIMING
VERIFICATION
(1) Remove front cylinder head cover and all 6
spark plugs.
(2) Rotate engine until the #2 piston is at TDC of
the compression stroke.
(3) Install a degree wheel on the crankshaft pulley.
(4) With proper adaptor, install a dial indicator
into #2 spark plug hole. Using the indicator find TDC
on the compression stroke.
(5) Position the degree wheel to zero.
(6) Remove dial indicator from spark plug hole.
(7) Place a 5.08 mm (0.200 in.) spacer between the
valve stem tip of #2 intake valve and rocker arm pad.
Allow tappet to bleed down to give a solid tappet
effect.
(8) Install a dial indicator so plunger contacts the
#2 intake valve spring retainer as nearly perpendic-
ular as possible. Zero the indicator.
(9) Rotate the engine clockwise until the intake
valve has lifted .254 mm (0.010 in.).
CAUTION: Do not turn crankshaft any further clock-
wise as intake valve might bottom and result in
serious damage.
(10) Degree wheel should read 6 degrees BTDC to
6 degrees ATDC.
STANDARD PROCEDURE - MEASURING
TIMING CHAIN WEAR
NOTE: This procedure must be performed with the
timing chain cover removed (Refer to 9 - ENGINE/
VALVE TIMING/TIMING CHAIN COVER - REMOVAL).
(1) Position a scale next to timing chain so that
any movement of chain may be measured (Fig. 132).
(2) Position a torque wrench and socket on the
camshaft sprocket attaching bolt. Apply force in the
direction of crankshaft rotation to take up slack to
the following torque:
²41 N´m (30 ft. lb.) with cylinder heads installed
²20 N´m (15 ft. lb.) with cylinder heads removed
NOTE: With torque applied to the camshaft
sprocket bolt, crankshaft should not be permitted to
move. It may be necessary to block crankshaft to
prevent rotation.
(3) Holding a measuring scale along edge of chain
links (Fig. 132).(4) Apply force in the reverse direction to the fol-
lowing torque:
²41 N´m (30 ft. lb.) with cylinder heads installed
²20 N´m (15 ft. lb.) with cylinder heads removed
(5) Measure amount of sprocket/chain movement.
(6) Install a new timing chain and sprockets if
movement exceeds 3.175 mm (1/8 in.).
