DESCRIPTION AND OPERATION
ENGINE IDENTIFICATION
The engine identification number is located on the
rear of the cylinder block (Fig. 1).
ENGINE LUBRICATION SYSTEM
OIL PAN
A structural die cast aluminum oil pan provides
lower engine protection as well as serving as the
engine oil reservoir. Oil pan is attached to block and
sealed with a gasket. The oil pickup tube has a
strainer and cover.
PRESSURE LUBRICATION
Oil drawn up through the pickup tube is pressur-
ized by the pump and routed through the full flow fil-
ter to the main oil gallery running the length of thecylinder block. Oil pickup, pump and check valve pro-
vide oil flow to the main oil gallery.
MAIN/ROD BEARINGS
A diagonal hole in each bulkhead feeds oil to each
main bearing. Drilled passages within the crankshaft
route oil from main bearing journals to connecting
rod journals.
CAMSHAFT/HYDRAULIC LASH ADJUSTERS
A vertical hole at the number five bulkhead routes
pressurized oil through a restrictor up past a cylin-
der head bolt to an oil gallery running the length of
the cylinder head. The camshaft journals are par-
tially slotted to allow a predetermined amount of
pressurized oil to pass into the bearing cap cavities
with small holes directed to spray lubricate the cam-
shaft lobes.

DESCRIPTION AND OPERATION
ENGINE IDENTIFICATION NUMBER
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 1).
ENGINE LUBRICATION
System is a full flow filtration, pressure feed type.
The oil pump is mounted behind the timing belt
cover. The pump inner rotor is driven by the crank-
shaft. The engine oil pan contains a baffle plate to
control oil level fluctuation during engine operation.
ENGINE COMPONENTS
BLOCK:The cylinder block is a light weight
design created by reducing thickness in many parts
and a short 10 mm (3/8 in.) block skirt. High rigidity
is provided with ribs cast in the outer wall, a full
length water jacket, and a mono-block or beam type,
main bearing cap. This single unit four bearing cap
is designed to control vibration of the cylinder block
partition walls.
CRANKSHAFT:A six throw, five weight crank-
shaft is supported by four main bearings with num-
ber three being the thrust bearing. The six separate
connecting rod throws pins reduce torque fluctua-tions while a torsional vibration damper is used to
control torsion caused vibration of the crankshaft.
Rubber lipped seals are used at front and rear. The

DESCRIPTION AND OPERATION
ENGINE IDENTIFICATION
The engine identification number is located on the
rear of the cylinder block just below the cylinder
head (Fig. 1).
ENGINE LUBRICATION SYSTEM
The lubrication system is a full flow filtration pres-
sure feed type. 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 chain case cover. The oil is
pumped through an oil filter and feeds a main oil
galley. This oil gallery feeds oil under pressure to the
main and rod bearings, camshaft bearings. Passages
in the cylinder block feed oil to the hydraulic lifters
and rocker shaft brackets which feeds the rocker arm
pivots (Fig. 2).
ENGINE COMPONENTS
ENGINE:The 3.3L (201 Cubic Inches) and 3.8L
(231 Cubic Inches) displacement engines are 60É V
type six cylinder power plants with cast iron cylinder
blocks and aluminum cylinder heads (Fig. 3). Firing
order for these engines is 1-2-3-4-5-6. High turbu-
lence cylinder heads allow a 8.9-1 compression ratio.
CRANKSHAFT:The nodular iron crankshaft is
supported by four main bearings, with number two
being the thrust bearing. Crankshaft end sealing is
provided by front and rear rubber seals.
PISTONS:The pistons are cast aluminum alloy.
Three rings are used. Piston pins, press fitted into
place, join the pistons to forged steel connecting rods.
CAMSHAFT:The nodular iron camshaft is
mounted in four steel backed babbitt bearings. A
thrust plate located in front of the first bearing, and
bolted to the block, controls end play. Silent timing
chain drives the camshaft. This chain is enclosed by
a cast aluminum cover which also carries a front
NS3.3/3.8L ENGINE 9 - 93

0.310 mm (0.012 in. Max.). If not within limits install
a new thrust plate.
(10) Each tappet reused must be installed in the
same position from which it was removed.When
camshaft is replaced, all of the tappets must be
replaced.
CAMSHAFT BEARINGS
REMOVAL
(1) With engine removed from vehicle and com-
pletely disassembled, drive out rear cam bearing core
hole plug.
(2) Install proper size adapters and horseshoe
washers (part of Tool C-3132-A) at back of each bear-
ing shell to be removed and drive out bearing shells
(Fig. 53).
INSTALLATION
(1) Install new camshaft bearings with Tool
C-3132-A by sliding the new camshaft bearing shell
over proper adapter.
(2) Position rear bearing in the tool. Install horse-
shoe lock and by reversing removal procedure, care-
fully drive bearing shell into place.
(3) Install remaining bearings in the same man-
ner. Bearings must be carefully aligned to bring oil
holes into full register with oil passages from the
main bearing. Number two bearing must index with
the oil passage to the left cylinder head and Number
three bearing must index with the oil passage to the
right cylinder head. If the camshaft bearing shell oil
holes are not in exact alignment, remove and rein-
stall them correctly. Install a new core hole plug at
the rear of camshaft.Be sure this plug does not
leak.
OIL PAN
REMOVAL
(1) Disconnect negative cable from battery and
remove engine oil dipstick.
(2) Raise vehicle on hoist and drain engine oil.(3) Remove bending brace to transaxle attaching
bolt.
(4) Remove bolts attaching dust cover to transaxle
housing. Lower dust cover to gain access to oil pan
bolts.
(5) Remove oil pan screws and remove oil pan.
INSTALLATION
(1) Clean surfaces and apply a 1/8 inch bead of
MopartSilicone Rubber Adhesive Sealant or equiva-
lent, at the parting line of the chain case cover and
the rear seal retainer (Fig. 54).
(2) Use a new pan gasket (Fig. 55).
(3) Install pan and tighten screws to 12 N´m (105
in. lb.).
(4) Install dust shield and bending brace to tran-
saxle housing.
(5) Lower vehicle and install oil dipstick.
(6) Connect negative cable to battery.
(7) Fill crankcase with oil to proper level.

(3) Remove front timing belt cover (Fig. 31).
CAUTION: Align camshaft and crankshaft timing
marks before removing the timing belt.
(4) Loosen timing belt tensioner fasteners (Fig. 33)
and remove timing belt and tensioner.
CAUTION: Do not loosen, tighten, or remove the
tensioner pivot bolt (Fig. 32).
CAMSHAFT AND CRANKSHAFT TIMING
PROCEDURE AND BELT INSTALLATION
ÐSOHC ENGINE
(1) When tensioner is removed from the engine it
is necessary to compress the plunger into the ten-
sioner body.(2) Place the tensioner into a vise equipped with
soft jaws and slowly compress the plunger (Fig. 34).
CAUTION: Index the tensioner in the vise the same
way it is installed on the engine. This is to ensure
proper pin orientation when tensioner is installed
on the engine.
(3) When plunger is compressed into the tensioner
body install a 1.9 mm (5/64) allen wrench or pin
through the body and plunger to retain plunger in
place until tensioner is installed.
(4) Set crankshaft sprocket to TDC by aligning the
sprocket with the arrow on the oil pump housing,
then back off to 3 notches before TDC (Fig. 35).
