1. Install intake manifold and new gaskets, with wiring
harness attached, to cylinder heads. Slide any wiring
harness clips onto appropriate bolts before installing.
Make sure gaskets are in proper orientation. Using
sequence shown, torque screws in 2 stages, first to
7.8 N·m (69 in. lb.), then to 10.5 N·m (93 in. lb.).
2. Install ground terminal to crankcase post with a
silver screw. Torque to 4.0 N·m (35 in. lb.) into used
holes or 6.2 N·m (55 in. lb.) in new holes.
3. Install wire harness clip to other crankcase post.
Torque to 4.0 N·m (35 in. lb.) into used holes or 6.2
N·m (55 in. lb.) in new holes.
4. Place wire harness conduit in clip and snap clip
together.
Install Fuel Injectors
NOTE: Ensure all parts are clean, undamaged and free
of debris and make sure electrical connectors
have seal in place.
O-rings and retaining clips should be replaced
any time fuel injector is separated from its
normal mounting position.
1. Lightly lubricate fuel injector O-rings with clean
engine oil.
2. Push retaining clip onto fuel injector, aligning clip as
shown.
3. Press fuel injector into fuel injector cap until retaining
clip snaps into place.
4. Press fuel injector into bore in intake manifold and
rotate to original position.
5. Install fuel injector cap screw into intake manifold
and torque to 7.3 N·m (65. in. lb.).
6. Push electrical connector on fuel injector making
sure a good connection is made.
7. Repeat steps 1 through 6 for other fuel injector.
Install Manifold Absolute Pressure (MAP) Sensor
(ECV EFI)
NOTE: Ensure all parts are clean, undamaged and free
of debris and make sure electrical connector has
seal in place.
1. Lightly oil MAP sensor O-ring and push MAP sensor
into bore in intake manifold.

2. Torque screw to 7.3 N·m (65 in. lb.).
3. Push electrical connector on MAP sensor making
sure a good connection is made.
Install Crankshaft Position Sensor

2. Snug screws and check air gap of sensor with a
feeler gauge. It must be 0.20-0.70 mm (0.008-0.027
in.).
3. Torque bracket screws to crankcase to 4.0 N·m (35
in. lb.) into used holes or 6.2 N·m (55 in. lb.) into
new holes.
4. Push electrical connector on crankshaft position
sensor making sure a good connection is made.

1. Make sure sealing surfaces are clean.
2. Make sure there are no nicks or burrs on sealing
surfaces.
3. Install a new O-ring in groove of each cover.
4. Position covers on cylinder heads. Locate cover with
oil separator hole on cylinder 1. Install screws in
each cover and finger tighten.
