3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected area of oil leak. If
the oil leak is found and identified, repair as necessary.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles), and repeat inspec-
tion.
5.If the oil leak source is not positively identified at this time, proceed with the air leak detection test method
as follows:
1. Disconnect the PCV hoses at the cylinder head covers and plug or cap the outlet on the covers.
2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kpa (3 PSI) of test pressure.
3. Gradually apply air pressure from 6.89 kPa (1 psi) to 17.23 kPa (2.5 psi) maximum while applying soapy water
at the suspected source. Adjust the regulator to the suitable test pressure that provides the best bubbles which
will pinpoint the leak source. If the oil leak is detected and identified, repair per service manual procedures.
4. If the leakage occurs at the crankshaft rear oil seal area, refer to the section, Inspection for Rear Seal Area
Leak.
6. If no leaks are detected, turn off the air supply. Remove the air hose, allplugs, and caps. Connect the PCV
hoses. Proceed to next step.
7. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the vehicle at various speeds approx-
imately 24 km (15 miles). Inspect the engine for signs of an oil leak by usinga black light.
NOTE: If oil leakage is observed at the dipstick tube to oil pan location; remove the tube, clean and reseal
using Mopar
Stud & Bearing Mount (press fit tube applications only), and for O-ring style tubes, remove
tube and replace the O-ring seal.
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in therear seal area of the engine, a more
involved inspection is necessary. The following steps should be followedto help pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area:
1. Disconnect the battery.
2. Raise the vehicle.
3. Remove clutch housing inspection cover and inspect rear of block for evidence of oil. Use a black light to check
for the oil leak. If a leak is present in this area, remove transmission for further inspection.
a. Circular spray pattern generally indicates seal leakage or crankshaftdamage.
b. Where leakage tends to run straight down, possible causes are a porous block, oil gallery cup plug or rear
crankshaft seal retainer gasket leak. See proper repair procedures for these items.
4. If no leaks are detected, pressurize the crankcase as previously described.
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch forleakage. If a leak is detected between
the crankshaft and seal while slowly turning the crankshaft, it is possible the crankshaft seal surface is damaged.
The seal area on the crankshaft could have minor nicks or scratches that canbe polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially machined to complement the function of the rear oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until disassembled.
7. After the oil leak root cause and appropriate corrective action have been identified, replace component(s) as
necessary.

material also will prevent corrosion. MoparGasket Sealant is available in a 13 oz. aerosol can or 4 oz./16 oz. can
w/applicator.
FORM-IN-PLACE GASKET AND SEALER APPLICATION
MoparGasket Maker material should be applied sparingly 1 mm (0.040 in.) diameter or less of sealant to one
gasket surface. Be certain the material surrounds each mounting hole. Excess material can easily be wiped off.
Components should be torqued in place within 15 minutes. The use of a locating dowel is recommended during
assembly to prevent smearing material off the location.
Mopar
Engine 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,a3.17mmor6.35mm(1/8in.
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 wettothetouch(within10minutes).The
usage of a locating dowel is recommended during assembly to prevent smearing material off the location.
Mopar
Gasket 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 shouldbeusedonengineswithmulti-
layer steel gaskets.
ENGINE GASKET SURFACE PREPARATION
To ensure engine gasket sealing, proper surface prep-
aration 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:
Metal scraper
Abrasive pad or paper to clean cylinder block
and head
High speed power tool with an abrasive pad or a
wire brush (1)
NOTE: Multi-Layer Steel (MLS) head gaskets
require a scratch free sealing surface.
Only use the following for cleaning gasket surfaces:
Solvent or a commercially available gasket
remover
Plastic or wood scraper (3)
Drill motor with 3M Roloc™ Bristle Disc (white or yellow) (2)
CAUTION: Excessive pressure or high RPM (beyond the recommended speed), can damage the sealing sur-
faces. The mild (white, 120 grit) bristle disc is recommended. If necessary, the medium (yellow, 80 grit) bris-
tle disc may be used on cast iron surfaces with care.
HYDROSTATIC LOCKED ENGINE
When an engine is suspected to be hydrostatically locked, regardless of what caused the problem, the following
steps should be used.
CAUTION: DO NOT use starter motor to rotate the engine, severe damage may occur.
1. Inspect air cleaner, induction system and intake manifold to ensure system is dry and clear of foreign material.
2. Remove negative battery cable.
3. Place a shop towel around the spark plugs when removing them from the engine. This will catch any fluid that
may possibly be in the cylinder under pressure.
4. With all spark plugs removed, rotate engine crankshaft using a breaker bar and socket.

30. Connect oil cooler lines (4) and connect the oil
pressure sensor (1) and oil temperature sensor
(5).
31. Install the power steering line support bracket at
the radiator.
32. Install lower radiator hose.
33. Connect the cooling fan hydraulic lines (Refer to 7

LATION).

correct level (Refer to LUBRICATION & MAINTE-
NANCE/FLUID TYPES - SPECIFICATIONS).

to 24 - HEATING & AIR CONDITIONING/PLUMB-
ING - STANDARD PROCEDURE).
39. Fill the cooling system (Refer to 7 - COOLING -
