DIAGNOSIS AND TESTING - INTAKE
MANIFOLD LEAKS
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.

STANDARD PROCEDURE
STANDARD PROCEDURE - MANIFOLD
STRIPPED THREAD REPAIR
The composite upper intake manifold thread
bosses, if stripped out, can be repaired by utilizing a
repair screw available through Mopartparts. Repair
screws are available for the following manifold
attached components:
²MAP sensor
²Power steering reservoir
²EGR tube
²Throttle cable bracket
The repair screws require a unique tightening
torque specification from the original screw. Refer to
the following chart for specification.

STANDARD PROCEDURE - INTAKE MANIFOLD
VACUUM PORT REPAIR
The composite intake manifold vacuum ports can
be repaired. Although, if the manifold plenum cham-
ber is damaged or cracked, the manifold must be
replaced.
To repair a broken or damaged vacuum nipple
(port) on the composite intake manifold, perform the
following procedure:
PARTS REQUIRED TOOLS REQUIRED
´ Brass Nipple ± 1/49
O.D. x 1/89pipe thread
(LDP/Speed Control Port)´ Pipe Tap ± 1/89-18
NPT
´ Drill Bit ± 11/329
´ File/Sandpaper
´ Brass Nipple ± 1/29
O.D. x 1/49pipe thread
(Brake Booster Port)´ Pipe Tap ± 1/49-18
NPT
´ Drill Bit ± 7/169
´ File/Sandpaper
NOTE: While performing this procedure, avoid get-
ting the manifold material residue into the plenum
chamber.
(1) File or sand the remaining port back until a
flat surface is obtained (plane normal to nipple (port)
axis).
(2) Drill out the nipple (port) base using a 7/16º
(brake booster port) or 11/32º (LDP/speed control port
) drill bit (Fig. 113).
(3) Using a 1/4º±18 NPT (brake booster port) or
1/8º±18 NPT (LDP/speed control port ) pipe tap, cut
internal threads (Fig. 113). Use caution to start tap
in a axis same as original nipple.
(4) Apply MopartThread Sealant to threads of
repair nipple(s).
(5) Install repair nipple(s). Do not over torque
repair nipple(s).
REMOVAL - UPPER INTAKE MANIFOLD
(1) Disconnect battery negative cable.
(2) Disconnect inlet air temperature (IAT) sensor
electrical connector.
(3) Remove air inlet resonator to throttle body
hose assembly.
(4) Disconnect throttle and speed control cables

INSTALLATION - UPPER INTAKE MANIFOLD
(1) If the following components were removed from
manifold, install and tighten to specifications:
CAUTION: The special screws used for the compos-
ite manifold attached components must be installed
slowly using hand tools only. This requirement is to
prevent the melting of material that causes stripped
threads. If threads become stripped, an oversize
repair screw is available. For more information and
procedure (Refer to 9 - ENGINE/MANIFOLDS/IN-
TAKE MANIFOLD - STANDARD PROCEDURE - MAN-
IFOLD STRIPPED THREAD REPAIR).

²Throttle cable bracket - 5.6 N´m (50 in. lbs.)
(2) Remove covering on lower intake manifold and
clean surfaces.
(3) Inspect manifold gasket condition. Gaskets can
be re-used, if not damaged. To replace, remove gasket
from upper manifold (Fig. 117). Position new gasket
in seal channel and press lightly in-place. Repeat
procedure for each gasket position.
(4) Position upper manifold on lower manifold (Fig.
117). Apply MopartLock & Seal Adhesive (Medium
Strength Threadlocker) to each upper intake mani-
fold bolt. Install and tighten bolts to 12 N´m (105 in.
lbs.) following torque sequence in (Fig. 118).
(5) Connect the MAP sensor electrical connector.(6) Connect the brake booster and LDP vacuum
hose to intake manifold (Fig. 116).
