1994 HONDA INTEGRA cylinder head

lnstallation
Installthe cylinder head in the reverse order of removal:
NOTE:
. Always use a new head and manifold gasket.
. The cylinder head gasket is a metal gasket Take care
not to bend it.
. Rotate the crankshaft, set the No. 1 piston at TDC
(page 6-51).
. Do not use the middle cover and lower cover for
storing items disassembled.
. Clean the middle cover and lower cover before instal-
lation.

2. Tighten cylinder head bolts in two steps. In the first
step, tighten all bolts in sequence to about 29 N'm
(3.0 kgf.m.22 lbf'ft). In the final step, tighten in
same sequence to 81 N.m (8.3 kgnm.60 lbf'ft).
NOTE: Apply clean engine oil to the bolt threads
and under the bolt head.

Adjust the valve clearance (see page 6-44).
Install the rubber seal in the groove of the cylinder
head cover. Seat the seal in the recesses for the
camshaft first, then work it into the groove around
the outside edges.
NOTE:
. Before installing the rubber seal. thoroughly
clean the seal and the groove.
. When installing, make sure the seal is seatedsecurely in the corners of the recesses with nogap.

14. Apply liquid gasket to the rubbe. seal at the eightcorne.s of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - 0001.. Check that the mating surfaces are clean and dry
before applying liquid gasket.
a Do not install the parts if 20 minutes or more
have elapsed since applying liquid gasket.
Instead,.eapply liquid gasket after removing oldresidue.
r After assembly, wait at least 20 minutes beforefilling the engine with oil.
Apply liquid gasket tothe shaded areas.

When installing the cylinder head cover. hold the
rubber seal in the groove by placing your fingers on
the camshaft contacting surfaces (top of the semi-
circles).
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the rubber seal.
NOTE:
Before installing the cylinder head cover, clean
the cylinder head contacting surfaces using a
shop towel.
Do not touch the pans where liquid gasket was
applied.

Throttle Body
Description
The throttle body is ot the single-barrel side-draft 1ype.
The lower portion of the throttle valve is heated by en-gine coolant from the cylinder head. The idle adjusting
screw which increases/dec.eases bvDass air and the
Evaporative Emission (EVAP) Control Canister port are
located on the top of the throttle body.

CAUTION: Do not adiust the thlottle stop screw. lt ispreset at the lactory.
1. Start the engine. Hold the engine at 3,OOO rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
2. Disconnect the vacuum hose (to the EVAP control
canister) from the top of the throttle body; connect
a vacuum, gauge to the throttle body.

3. Allow the engine to idle and check that the gauge
indicates no vacuum.
a li there is vacuum, check the throttle cable (see
page 1 1-'l 18, 119).
Check that vacuum is indicated on the gauge when
the throttle is opened slightly from idle.
a lf the gauge indicates no vacuum, check the throt-
tle body port. lf the throttle body port is clogged.
clean it with carburetor cleaner.
Stop the engine and check that the throttle cable
operates smoothly without binding or sticking.
a lf there are any abnormalities in the above steps,
check for:
- Excessive wear or Dlav in the throttle valve shaft.
Sticky or binding throttle lever at full close po-
srtron.
Clearance between throttle stop screw and throt-
tle lever at tull close Dosition.

Pressure Control
Low assist at higher speeds:
When steering resistance is low. such as when driving at high speeds. or when driving straight ahead, the input shaft is
near or in the neutral position, so there is little or no flow to any of the power cylinder orifices, Most of the feed pressure
trom the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cylin-
der, resulting in low or no assist.
vaz =- S\->/-\7/RETURN PASSAGE(To RESERVOIRI
VALVE UNITINPUT SHAFT
High assist at lower speeds:
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
difference in angle created between the input shaft and the valve opens the fluid passage on one side, and closes the fluid
passage on the other side, at each pair of orifices. The fluid pressure increases in the side of the power cylinder fed by the
larger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through the
input shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-
ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example. when parking or making low speed turns). and the passages become smaller and
power assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ah€ad).
