MOPARtGASKET SEALANT
MopartGasket Sealant is a slow drying, perma-
nently soft sealer. This material is recommended for
sealing threaded fittings and gaskets against leakage
of oil and coolant. Can be used on threaded and
machined parts under all temperatures. This mate-
rial is used on engines with multi-layer steel (MLS)
cylinder head gaskets. This material also will pre-
vent corrosion. MopartGasket Sealant is available in
a 13 oz. aerosol can or 4 oz./16 oz. can w/applicator.
FORM-IN-PLACE GASKET AND SEALER
APPLICATION
Assembling parts using a form-in-place gasket
requires care but it's easier then using precut gas-
kets.
MopartGasket Maker material should be applied
sparingly 1 mm (0.040 in.) diameter or less of sealant
to one gasket surface. Be certain the material sur-
rounds each mounting hole. Excess material can eas-
ily be wiped off. Components should be torqued in
place within 15 minutes. The use of a locating dowel
is recommended during assembly to prevent smear-
ing material off the location.
MopartEngine RTV GEN II or ATF RTV gasket
material should be applied in a continuous bead
approximately 3 mm (0.120 in.) in diameter. All
mounting holes must be circled. For corner sealing, a
3.17 or 6.35 mm (1/8 or 1/4 in.) drop is placed in the
center of the gasket contact area. Uncured sealant
may be removed with a shop towel. Components
should be torqued in place while the sealant is still
wet to the touch (within 10 minutes). The usage of a
locating dowel is recommended during assembly to
prevent smearing material off the location.
MopartGasket Sealant in an aerosol can should be
applied using a thin, even coat sprayed completely
over both surfaces to be joined, and both sides of a
gasket. Then proceed with assembly. Material in a
can w/applicator can be brushed on evenly over the
sealing surfaces. Material in an aerosol can should be
used on engines with multi-layer steel gaskets.
ENGINE GASKET SURFACE PREPARATION
To ensure engine gasket sealing, proper surface
preparation must be performed, especially with the
use of aluminum engine components and multi-layer
steel cylinder head gaskets.
Neveruse the following to clean gasket surfaces:
²Metal scraper
²Abrasive pad or paper to clean cylinder block
and head
²High speed power tool with an abrasive pad or a
wire brush (Fig. 1)NOTE: Multi-Layer Steel (MLS) head gaskets
require a scratch free sealing surface.
Only use the following for cleaning gasket surfaces:
²Solvent or a commercially available gasket
remover
²Plastic or wood scraper (Fig. 1)
²Drill motor with 3M RolocyBristle Disc (white
or yellow) (Fig. 1)
CAUTION: Excessive pressure or high RPM can
damage the sealing surfaces. The mild (white, 120
grit) bristle disc is recommended. If necessary, the
medium (yellow, 80 grit) bristle disc may be used
on cast iron surfaces with care.
CRANKSHAFT DAMPER BOLT ACCESS PLUG
An access plug is located in the right splash shield
(Fig. 2). Remove the plug and insert the proper size
socket, extension and ratchet, when crankshaft rota-
tion is necessary.

DIAGNOSIS AND TESTING
GENERAL INFORMATION
Engine diagnosis is helpful in determining the
causes of malfunctions not detected and remedied by
routine maintenance.
These malfunctions may be classified as either
mechanical (e.g., a strange noise), or performance
(e.g., engine idles rough and stalls).
Refer to the Service DiagnosisÐMechanical Chart
and the Service DiagnosisÐPerformance Chart, for
possible causes and corrections of malfunctions. Refer
to Group 14, Fuel System, for the fuel system diag-
nosis.
Additional tests and diagnostic procedures may be
necessary for specific engine malfunctions that can-
not be isolated with the Service Diagnosis charts.
Information concerning additional tests and diagno-
sis is provided within the following:
²Cylinder Compression Pressure Test
²Cylinder Combustion Pressure Leakage Test
²Engine Cylinder Head Gasket Failure Diagnosis
²Intake Manifold Leakage Diagnosis
INTAKE MANIFOLD LEAKAGE DIAGNOSIS
An intake manifold air leak is characterized by
lower than normal manifold vacuum. Also, one or
more cylinders may not be functioning.
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING. DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR
HANDS NEAR THE PULLEYS, BELTS OR THE FAN.
DO NOT WEAR LOOSE CLOTHING.
(1) Start the engine.
(2) Spray a small stream of water (Spray Bottle) at
the suspected leak area.
(3) If engine RPM'S change, the area of the sus-
pected leak has been found.
(4) Repair as required.
CYLINDER COMPRESSION PRESSURE TEST
The results of a cylinder compression pressure test
can be utilized to diagnose several engine malfunc-
tions.
Ensure the battery is completely charged and the
engine starter motor is in good operating condition.
Otherwise the indicated compression pressures may
not be valid for diagnosis purposes.
(1) Check engine oil level and add oil if necessary.
(2) Drive the vehicle until engine reaches normal
operating temperature. Select a route free from traf-
fic and other forms of congestion, observe all traffic
laws, and accelerate through the gears several times
briskly.
(3) Remove all spark plugs from engine. As spark
plugs are being removed, check electrodes for abnor-
mal firing indicators fouled, hot, oily, etc. Record cyl-
inder number of spark plug for future reference.
(4) Disconnect coil wire from distributor and
secure to good ground to prevent a spark from start-
ing a fire (Conventional Ignition System). For Direct
Ignition System DIS disconnect the coil connector.
(5) Be sure throttle blade is fully open during the
compression check.
(6) Insert compression gage adaptor into the #1
spark plug hole in cylinder head. Crank engine until
maximum pressure is reached on gage. Record this
pressure as #1 cylinder pressure.
(7) Repeat the previous step for all remaining cyl-
inders.
(8) Compression should not be less than (689 kPa)
100 psi and not vary more than 25 percent from cyl-
inder to cylinder.
(9) If one or more cylinders have abnormally low
compression pressures, repeat the compression test.
(10) If the same cylinder or cylinders repeat an
abnormally low reading on the second compression
test, it could indicate the existence of a problem in
the cylinder in question.The recommended com-
pression pressures are to be used only as a
guide to diagnosing engine problems. An engine

DIAGNOSIS AND TESTING (Continued)

CRANKSHAFT
A nodular cast iron crankshaft is used. The engine
has five main bearings. The number three main is
flanged to control thrust. The mains and connecting
rod journals have undercut fillet radiuses that are
deep rolled for added strength. To optimize bearing
loading, eight counterweights are used. Hydrody-
namic seals provide end sealing, where the crank-
shaft 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 transmits crankshaft movement, via timing
belt to the camshaft sprocket providing timed valve
actuation.
PISTONS
The engineDOES NOThave provision 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. The engine uses pressed-in
piston pins to attach forged powdered metal connect-
ing 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. Pistons and connecting rods are serviced as
an assembly.
PISTON RINGS
The piston rings include a molybdenum faced top
ring for reliable compression sealing and a taper
faced intermediate ring for additional cylinder pres-
sure control. Oil Control Ring Package consist of two
steel rails and an expander spacer.
CYLINDER HEAD
The aluminum cylinder head features a Single
Over Head Camshaft (SOHC), four-valves per cylin-
der, cross flow design. The valves are arranged in
two inline banks, with the two intake per cylinder
facing toward the radiator. The exhaust valves facing
toward the dash panel. Rocker arm shafts mount
directly to the cylinder head. It incorporates powder
metal valve guides and seats. The hollow rocker arm
shafts supplies oil to the hydraulic lash adjusters,
camshaft and valve mechanisms.
CAMSHAFT
The nodular iron camshaft has five bearing jour-
nals and three cam lobes per cylinder. Provision for a
cam position sensor is provided on the camshaft at
the rear of cylinder head which also acts as thrust
plate. A hydrodynamic oil seal is used for oil control
at the front of the camshaft.
VALVES
Four valves per cylinder are actuated by roller
rocker arms/hydraulic lash adjusters assemblies
which pivot on rocker arm shafts. All valves have
chrome plated valve stems. Viton rubber valve stem
seals are integral with spring seats. Valve springs,
spring retainers, and locks are conventional design.
INTAKE MANIFOLD
The intake manifold is a molded plastic composi-
tion, attached to the cylinder head with five fasten-
ers. This long branch design enhances low and mid-
range torque.
EXHAUST MANIFOLD
The exhaust manifold is made of nodular cast iron
for strength and high temperatures. Exhaust gasses
exit the manifold into an articulated joint connection
and exhaust pipe.

ENGINE LUBRICATION SYSTEM
ENGINE LUBRICATION
Refer to Group 0, Lubrication and Maintenance for
recommended oil capacity to be used in various
engine application. System is full flow filtration,
pressure feed type. The oil pump is mounted in the
front engine cover and driven by the crankshaft.
Pressurized oil is then routed through the main oil
gallery, running the length of the cylinder block, sup-
plying main and rod bearings with further routing.
Rod bearing oil throw-off lubricates the pistons from
directed slots on the side of the connecting rod
assemblies. Camshaft and valve mechanisms are
lubricated from a full-length cylinder head oil gallery
supplied from the crankcase main oil gallery.
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 the
cylinder block. A cylinder head restrictor, integral to
the cylinder head gasket, provides increased oil flow
to the main oil gallery (Fig. 2).
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
