Installation

1. Set No.1 piston at TDC on its compression stroke as follows:

Set TDC - Crankshaft Pulley:

Set TDC - Distributor:

(1) Align mark on crankshaft pulley with "0°" position and confirm that distributor rotor head is set to No.1 position as shown in figures.

Camshaft Knock Pin Position:

(2) Confirm that knock pin on camshaft is set at the top.

Head Bolt Tightening Sequence:

CAUTION: Do not rotate crankshaft and camshaft separately, or valves will hit piston heads.

2. Install cylinder head with new gasket and tighten cylinder head bolts in numerical order.

Tightening procedure:

(1) Tighten all bolts to: 29 N-m (22 ft.lb.).

(2) Then, tighten all bolts to: 78 N-m (58 ft.lb.).

(3) Loosen all bolts completely.
(4) Tighten all bolts to: 29 N-m (22 ft.lb.).

(5) Turn all bolts 80 to 85 degrees clockwise with an angle wrench, or if an angle wrench is not available, tighten all bolts to: 74 to 83 N-m (54 to 61 ft.lb.).

Camshaft Alignment Marks:

3. Set chain on camshaft sprocket by aligning each mating mark. Then install camshaft sprocket to camshaft.

Camshaft Sprocket Bolt:

4. Tighten camshaft sprocket bolt.
Torque to: 118 - 157 N-m (87 - 116 ft.lb.)

5. Install rubber plugs as follows:

CAUTION:
- Rubber plugs should be installed within 5 minutes of applying liquid gasket.
- Rubber plugs should be replaced with new ones.

Valve Cover Rubber Plugs:

(1) Apply liquid gasket to rubber plugs.

Installing Rubber Plugs:

(2) Install rubber plugs, then move them with your fingers to uniformly spread the liquid gasket on cylinder head surface.

Proper Rubber Plug Installation:

- Rubber plugs should be installed flush with the surface.
- Do not start the engine for 30 minutes after installing rocker cover.
- Wipe clean excessive liquid gasket from cylinder head top surface.

Checking For Air In Rocker Arm:

6. Check hydraulic valve lifter.
(1) Push hydraulic valve lifter forcefully with your finger.

CAUTION: Be sure to check it with rocker arm in its free position.

(2) If valve lifter moves more than 1 mm (0.04 in), air may be inside of it.
(3) Bleed air off by running engine at 1,000 rpm under no-load for about 20 minutes.
(4) If hydraulic valve lifters are still noisy, replace them and bleed air off again, in the same manner as in step (3).

7. Install rocker cover.

CAUTION: Be sure to avoid interference between rocker cover and rocker arm.

Rocker Cover Bolts - First Step:

Tighten bolts as follows:
(1) Tighten 2 bolts to: 3 N-m (2.2 ft.lb.) temporarily in order shown in image.

Rocker Cover Bolts - Final Step:

(2) Then tighten all bolts to: 7 to 10 N-m (5.1 to 7.2 ft.lb.) in order shown in image.

8. Install any parts removed, including the following:

Tightening Sequence:

- Intake manifold.
Tighten bolts in order shown.
Torque to: 16 - 21 N-m (12 - 15 ft.lb.)

- Intake manifold stay.

Tightening Sequence:

- Intake manifold collector.
Tighten bolts in order shown.
Torque to: 16 - 21 N-m (12 - 15 ft.lb.)

Exhaust Manifold Tightening Sequence:

- Exhaust manifold.
Torque bolts in order shown.
Torque to: 16 - 21 N-m (12 - 15 ft.lb.)
