Service Precautions

Handling of Special Nuts and Bolts

Because the front sub frame sections on this vehicle are

constructed with aluminum alloys, use only the special

"Dacro" type nuts and bolts recommended by Acura.

NOTE:

• Dacro finish can be identified by gray plating.

• Some Dacro finish bolts have a green coating on the

thread section of the bolt for easier application. This

type of bolt is called a "Torquer" bolt.

• Use of other types of nuts and bolts may cause elec-

trolysis and corrosion which in turn could cause the

bolt to loosen.

of some bolts.

Gray plating: "Dacro" type

Gray plating + Green coating on the threads:

"Torquer" type
1. When replacing nuts and bolts, use only the same

type.

2. Tighten the nuts and bolts with a torque wrench to

the specifications provided in this manual.

3. Clean all thread ridges with a non-wire-type bristle

brush. Foreign matter in the threads may cause the

bolt to loosen.

4. Sections on this vehicle requiring the use of Dacro

nuts and bolts will be indicated by a (#) in this man-

ual.ProCarManuals.com

44. Disconnect the vacuum hoses, then remove the front

engine mounts.

engine and the transmission.

Attach the transmission jack with a rubber pad or a

wooden block to protect the transmission housing.

48. Reinstall the mid mounts to the transmission and

retorque the mounting bolts.

49. Raise the chain hoist to remove all slack from the

chain.

50. Check that the engine is completely free of vacuum

hoses, fuel and coolant hoses and electrical wiring.

51. Slowly raise the engine approximately 150 mm (6 in).

Check once again that all hoses and wires are discon-

nected from the engine.

52. Raise the engine all the way up, and remove it from

the vehicle.ProCarManuals.com

Camshaft

Inspection

NOTE:

• Do not rotate the camshaft during inspection.

• Remove the rocker arms and rocker shafts.

1. Put the camshaft and the camshaft holders on the

cylinder head, then tighten the bolts to the specified

torque.

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:

2. Seat the camshaft by pushing it toward the distributor

end of cylinder head.

3. Zero the dial indicator against the end of the distrib-

utor drive, then push the camshaft back and forth

and read the end play.

Camshaft End Play:

Standard (New): 0.05 - 0.15 mm

(0.002 - 0.006 in)

Service Limit: 0.5 mm (0.02 in)
4. Remove the bolts, then remove the camshaft hold-

ers from the cylinder head.

— Lift the camshaft out of the cylinder head, wipe it

clean,
then
inspect
the
lift
ramps.
Replace
the

camshaft if lobes are pitted, scored, or excessively

worn.

— Clean the camshaft bearing surfaces in the cylin-

der head, then set the camshaft back in place.

— Insert a plastigage strip across each journal.

5. Install the camshaft holders, then tighten the bolts

to the specified torque shown in the left column of

this page.

6. Remove the camshaft holders. Measure the widest

portion of plastigage on each journal.

Camshaft-to-Holder Oil Clearance:

Standard (New): 0.050 - 0.089 mm

(0.0020 - 0.0035 in)

Service Limit: 0.15 mm (0.006 in)

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)

Cylinder Head

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

Connecting Rod Bearings

Clearance

1. Remove the connecting rod cap and bearing half.

2. Clean the crankshaft rod journal and bearing half

with a clean shop towel.

3. Place the plastigage across the rod journal.

4. Reinstall the bearing half and cap, and torque the

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

NOTE: Do not rotate the crankshaft during inspec-

tion.

5. Remove the rod cap and bearing half, and measure

the widest part of the plastigage.

Connecting Rod Bearing-to-Journal Oil Clearance:

Standard (New): 0.015 - 0.043 mm

(0.0006 - 0.0017 in)

Service Limit: 0.05 mm (0.002 in)

PLASTIGAGE STRIP

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

remove the upper half of the bearing, install a new,

complete bearing with the same color code (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 clear-

ance 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
