REMOVAL AND INSTALLATION (Continued)

(11) Install oil pump. If crankshaft end play is to
be checked refer to service procedures in this section.
(12) Install crankshaft sprocket.
(13) Install oil filter adapter and filter.
(14) Install oil pan and structural collar. Refer to
procedures outlined in the section.
(15) Perform camshaft and crankshaft timing
relearn procedure as follows:
²Connect the DRB scan tool to the data link
(diagnostic) connector. This connector is located in
the passenger compartment; at the lower edge of
instrument panel; near the steering column.
²Turn the ignition switch on and access the ªmis-
cellaneousº screen.
²Select ªre-learn cam/crankº option and follow
directions on DRB screen.
OIL FILTER ADAPTER
REMOVE AND INSTALL
Ensure O-ring is in the groove on adapter. Align
roll pin into engine block and tighten assembly to 80
N´m (60 ft. lbs.) (Fig. 83).
OIL FILTER
REMOVE AND INSTALL
CAUTION: When servicing the oil filter (Fig. 84)
avoid deforming the filter, install tool band strap
against the seam at the base of the filter. The seam,
joining the can to the base is reinforced by the
base plate.
(1) Turn counterclockwise to remove.
(2) To install, lubricate new filter gasket. Check
filter mounting surface. The surface must be smooth,
flat and free of debris or old pieces of rubber. Screw
filter on until gasket contacts base. Tighten to 21
N´m (15 ft. lbs.).
OIL PUMP
REMOVAL
(1) Disconnect negative cable from battery.(2) Remove Timing Belt. Refer to procedure in this
section.
(3) Remove Oil Pan. Refer to procedure in this sec-
tion.
(4) Remove Crankshaft Sprocket using Special Tool
6793 and insert C-4685-C2 (Fig. 85).
(5) Remove oil pick-up tube.
(6) Remove oil pump (Fig. 86) and front crankshaft
seal.
INSTALLATION
(1) Make sure all surfaces are clean and free of oil
and dirt.
(2) Apply MopartGasket Maker to oil pump as
shown in (Fig. 87). Install oil ring into oil pump body
discharge passage.
(3) Prime oil pump before installation.
(4) Align oil pump rotor flats with flats on crank-
shaft as you install the oil pump to the block.
NOTE: Front crankshaft seal MUST be out of pump
to align, or damage may result.

REMOVAL AND INSTALLATION (Continued)

PISTON AND CONNECTING ROD
REMOVAL
(1) Remove top ridge of cylinder bores with a reli-
able ridge reamer before removing pistons from cyl-
inder block.Be sure to keep tops of pistons
covered during this operation. Mark piston with
matching cylinder number (Fig. 90).
(2) Remove oil pan. Scribe the cylinder number on
the side of the rod and cap (Fig. 91) for identification.(3) Pistons will have a stamping in the approxi-
mate location shown in (Fig. 90). These stamps will
be either a directional arrow or a weight identifica-
tion for the assembly. L is for light and H is for
heavy. These assemblies should all be the same
weight class. Service piston assemblies are marked
with a S and can be used with either L or H produc-
tion assemblies. The weight designation stamps
should face toward the timing belt side of the engine.
(4) Pistons and connecting rods must be removed
from top of cylinder block. Rotate crankshaft so that
each connecting rod is centered in cylinder bore.
(5) Remove connecting rod cap boltsDo not use
old bolts if reinstalling connecting rod.Push
each piston and rod assembly out of cylinder bore.
NOTE: Be careful not to nick crankshaft journals.
(6) After removal, install bearing cap on the mat-
ing rod.
(7) Piston and Rods are serviced as an assembly.
PISTON RINGÐREMOVAL
(1) ID mark on face of upper and intermediate pis-
ton rings must point toward piston crown.
(2) Using a suitable ring expander, remove upper
and intermediate piston rings (Fig. 92).
(3) Remove the upper oil ring side rail, lower oil
ring side rail and then oil ring expander from piston.
(4) Clean ring grooves of any carbon deposits.
PISTON RINGSÐINSTALLATION
(1) Install rings with manufacturers I.D. mark fac-
ing up, to the top of the piston (Fig. 93).
CAUTION: Install piston rings in the following
order:
a. Oil ring expander.
b. Upper oil ring side rail.

incorporates main bearing caps. Rear seal retainer is
integral with the block.
CRANKSHAFTA nodular cast iron crankshaft is
used. The engine has 5 main bearings, with number
3 flanged to control thrust. The 52 mm diameter
main and 48 mm diameter crank pin journals (all)
have undercut fillet radiuses that are deep rolled for
added strength. To optimize bearing loading 8 coun-
terweights are used. Hydrodynamic seals provide end
sealing, where the crankshaft exits the block.
Anaerobic gasket material is used for parting line
sealing. A sintered iron timing belt sprocket is
mounted on the crankshaft nose. This sprocket pro-
vides motive power; via timing belt to the camshaft
sprocket providing timed valve actuation.
PISTONSThe DOHC EngineDO NOThave pro-
vision for a free wheeling valve train. Non free
wheeling valve train means, in the event of a broken
timing belt Pistons will contact the Valves. All
engines use pressed-in piston pins to attach forged
powdered metal connecting rods. The connecting rods
are a cracked cap design and are not repairable. Hex
head cap screw are used to provide alignment and
durability in the assembly.
PISTON RINGSThe piston rings include a
molybdenum faced top ring for reliable compression
sealing and a taper faced intermediate ring for addi-
tional cylinder pressure control. Oil Control Ring
Package contains of 2 steel rails and a expander
spacer.
CYLINDER HEADFeatures a Dual Over Head
Camshaft (DOHC), 4 valves per cylinder cross flow
design. The valves are arranged in two in-line banks,
with the ports of the bank of two intake valves per
cylinder facing toward the radiator side of engine
and ports of the bank of two exhaust valves per cyl-
inder facing toward the dash panel. Incorporates
powder metal valve guides and seats. Integral oil gal-
leys within the cylinder head supplies oil to the
hydraulic lash adjusters, camshaft and valve mecha-
nisms.
CAMSHAFTSThe nodular iron camshafts have
six bearing journals and 2 cam lobes per cylinder.
Flanges at the rear journals control camshaft end
play. Provision for cam position sensor is located on
the intake camshaft at the rear of cylinder head. A
hydrodynamic oil seal is used for oil control at the
front of the camshaft.
VA LV E SFour valves per cylinder are actuated by
roller cam followers which pivot on stationary
hydraulic lash adjusters. All valves have 6 mm diam-
eter chrome plated valve stems. The valve sizes are
34.8 mm (1.370 inch.) diameter intake valves and
30.5 mm (1.20 inch.) diameter exhaust valves. Viton
rubber valve stem seals are integral with the springseats. Valve springs, spring retainers, and locks are
conventional.
INTAKE MANIFOLDThe intake manifold is a
two piece aluminum casting, attached to the cylinder
head with ten fasteners. This long branch fan design
enhances low and mid-speed torque.
EXHAUST MANIFOLDThe exhaust manifold is
made of nodular cast iron for strength and high tem-
peratures. Exhaust gasses exit through a machined,
articulated joint connection to the exhaust pipe.

DIAGNOSIS AND TESTING
CHECKING ENGINE OIL PRESSURE
(1) Remove oil pressure switch and install gauge
assembly C-3292 with adaptor.
(2) Run engine until thermostat opens.
CAUTION: If oil pressure is 0 at idle, Do Not per-
form the 3000 RPM test in the next step.
(3) Oil Pressure:Curb Idle25 kPa (4 psi) mini-
mum3000 RPM170-550 kPa (25-80 psi).
(4) If oil pressure is 0 at idle. Shut off engine,
check for pressure relief valve stuck open, a clogged
oil pick-up screen or a damaged oil pick-up tube
O-ring.
SERVICE PROCEDURES
CYLINDER BORE AND PISTON SIZING
The cylinder walls should be checked for out-of-
round and taper with Tool C-119 (Fig. 4). The cylin-
der bore out-of-round is 0.050 mm (.002 inch)
maximum and cylinder bore taper is 0.051 mm (0.002
inch) maximum. If the cylinder walls are badly
scuffed or scored, the cylinder block should be
rebored and honed, and new pistons and rings fitted.
Whatever type of boring equipment is used, boring
and honing operation should be closely coordinated
