4. Tighten each bolt two turns at a time in the sequence

shown below to ensure that the rockers do not bind

on the valves.

Specified torque:

8 mm bolts: 22 N-m (2.2 kgf-m, 16 Ibf-ft)

Apply engine oil

6 mm bolts: 12 N-m (1.2 kgf-m, 8.7 Ibf-ft)

Apply engine oil

6 mm bolts:

5. Torque the bolts in the sequence shown.ProCarManuals.com

Installation (cont'd)

14. Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

• Use liquid gasket. Part No. 08718 - 0001 or 08718

- 0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Do not install the parts if five minutes or more

have elapsed since applying liquid gasket. Instead,

reapply liquid gasket after removing old residue.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

15.
Apply liquid gasket to

the shaded areas.

When installing the cylinder head cover, hold the

head cover gasket in the groove by placing your fin-

gers on the camshaft contacting surfaces (top of the

semicircles).

Once the cylinder head cover is on the cylinder

head, slide the cover slightly back and forth to seat

the head cover gasket.

NOTE:

• Before installing the cylinder head cover, clean

the cylinder head contacting surfaces with a

shop towel.

• Do not touch the parts where liquid gasket was

applied.

• Replace the washer when damaged or deterio-

rated.

• Reconnect the grounds cables to the cylinder

head cover.
16. Tighten the nuts in two or three steps. In the final step,

torque all nuts, in sequence, to 12 N-m (1.2 kgf-m, 8.7

Ibf-ft).

NOTE:

• Be sure to wipe any liquid gasket off the surface

of the No. 7 camshaft holder where the distribu-

tor is to be attached.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

17. After installation, check that all tubes, hoses and

connectors are installed correctly.

18. Enter the anti-theft code for the radio, then enter the

customer's radio station presets.

Main Bearings

Clearance

1. To check main bearing-to-journal oil clearance,

remove the main caps and bearing halves.

2. Clean each main journal and bearing half with a

clean shop towel.

3. Place one strip of plastigage across each main jour-

nal.

NOTE: If the engine is still in the car when you bolt

the main cap down to check clearance, the weight

of the crankshaft and flywheel will flatten the plasti-

gage further than just the torque on the cap bolt

and give you an incorrect reading. For an accurate

reading, support the crankshaft with a jack under

the counterweights and check only one bearing at a

time.

4. Reinstall the bearings and caps, then torque the

bolts.

1st step: 29 N-m (3.0 kgf-m, 22 Ibf-ft)

Final step: 74 N-m (7.5 kgf-m, 54 Ibf-ft)

NOTE: Do not rotate the crankshaft during inspec-

tion.

5. Remove the caps, and bearings again, and measure

the widest part of the plastigage.

Main Bearing-to-Journal Oil Clearance:

Standard (New): 0.018 - 0.048 mm

(0.0007 - 0.0019 in)

Service Limit: 0.053 mm (0.0021 in)

6. If the plastigage measures too wide or too narrow,

remove the crankshaft, and remove the upper half

of the bearing. '95 and '96 only: Install a new, com-

plete bearing with the same color (select the color

as shown in the right column of this page), and

recheck the clearance.

CAUTION: Do not file, shim, or scrape the bearings

or the caps to adjust clearance.

7. If the plastigage shows the clearance is still incor-

rect, try the next larger or smaller bearing (the color

listed above or below that one), and check again.

NOTE: If the proper clearance cannot be obtained

by using the appropriate larger or smaller bearings,

replace the crankshaft and start over.ProCarManuals.com

Pistons

Installation

Before installing the piston, apply a coat of

engine oil to the ring grooves and cylinder

bores.

1. If the crankshaft is already installed:

Remove the connecting rod caps and slip short

sections of rubber hose over the threaded ends

of the connecting rod bolts.

Install the ring compressor, check that the bear-

ing is securely in place, then position the piston

in the cylinder and tap it in using the wooden

handle of a hammer.

Stop tapping after the ring compressor pops

free, and check the connecting rod-to-crank jour-

nal alignment before pushing piston into place.

Install the rod caps with bearings, and torque the

nuts to 32 N-m (3.3 kgf-m, 24 Ibf-ft)

2. If the crankshaft is not installed:

Remove the rod caps and bearings, install the

ring compressor, then position the piston in the

cylinder and tap it in using the wooden handle of

a hammer.

Position all pistons at top dead center.

The arrow must face

the timing belt side

of the engine and the

connecting rod oil hole

must face the intake

manifold.

CONNECTING ROD

OIL HOLE

RUBBER HOSES

NOTE: Maintain downward force on the ring com-

pressor to prevent rings from expanding before

entering the cylinder bore.

Use the wooden handle

of a hammer to push, or

tap the piston into the

cylinder bore.

Engine Oil

Inspection

1. Check engine oil level with the engine off and the car

parked on level ground.

2. Make certain that the oil level indicated on the dip-

stick is between the upper and lower marks.

3. If the level has dropped close to the lower mark, add

oil until it reaches the upper mark.

CAUTION: Insert the dipstick carefully to avoid

bending it.ProCarManuals.com
