Fuel Pressure

7. Fuel Pressure

A: INSPECTION

WARNING:
Before removing the fuel pressure gauge, re-
lease the fuel pressure.

NOTE:
When the fuel pressure is out of standard, check or
replace the pressure regulator and pressure regu-
lator vacuum hose.
1) Remove the collector cover.
2) Release the fuel pressure. <Ref. to
FU(H4DOTC)-39, RELEASING OF FUEL PRES-
SURE, PROCEDURE, Fuel.>
3) Open the fuel filler flap lid, and remove the fuel
filler cap.
4) Disconnect the fuel delivery hose and connect
fuel pressure gauge.
5) Install the fuse of fuel pump to main fuse box.

6) Start the engine.
7) Measure the fuel pressure while disconnecting
pressure regulator vacuum hose from intake mani-
fold.

Fuel pressure:

Standard: 284 — 314 kPa (2.9 — 3.2 kgf/cm

2

41 — 46 psi)

8) After connecting the pressure regulator vacuum
hose, measure the fuel pressure.

Fuel pressure:

Standard: 230 — 260 kPa (2.35 — 2.65 kgf/
cm

2

, 33 — 38 psi)

NOTE:
The fuel pressure gauge registers 10 to 20 kPa (0.1
to 0.2 kgf/cm

2

, 1 to 3 psi) higher than standard dur-

ing high-altitude operations.

Valve Clearance

8. Valve Clearance

A: INSPECTION

Inspection and adjustment of valve clearance
should be performed while engine is cold.
1) Lift-up the vehicle.
2) Remove the under cover.
3) Lower the vehicle.
4) Remove the collector cover.
5) Disconnect the ground cable from battery.

6) Remove the air intake duct. <Ref. to
IN(H4DOTC)-9, REMOVAL, Air Intake Duct.>
7) Remove the bolt which secures timing belt cover
(RH).
8) Loosen the remaining bolt which secures timing
belt cover (RH), then remove the timing belt cover.
9) When inspecting #1 and #3 cylinders:

(1) Remove the air cleaner case. <Ref. to
IN(H4DOTC)-8, REMOVAL, Air Cleaner Case.>
(2) Disconnect the connector from ignition coil.
(3) Remove the ignition coil.
(4) Place a suitable container under the vehicle.
(5) Disconnect the PCV hose from rocker cover
(RH).
(6) Remove the bolts, then remove the rocker
cover (RH).

10) When inspecting #2 and #4 cylinders:

(1) Disconnect the battery cable, and then re-
move the battery and battery carrier.
(2) Disconnect the connector of ignition coil.
(3) Remove the ignition coil.
(4) Place a suitable container under the vehicle.
(5) Disconnect the PCV hose from rocker cover
(LH).
(6) Remove the bolts, then remove the rocker
cover (LH).

11) Turn the crank pulley clockwise until arrow
mark on the cam sprocket is set to position shown
in the figure.

NOTE:
Turn the crankshaft using socket wrench.

12) Measure the clearance between #1 cylinder in-
take valve and #3 cylinder exhaust valve by using
thickness gauge (A).

NOTE:
• Insert the thickness gauge in a direction as hori-
zontal as possible with respect to the valve lifter.
• Measure the exhaust valve clearances while lift-
ing-up the vehicle.

Valve clearance :

Intake

0.20

±

0.02 mm (0.0079

±

0.0008 in)

Exhaust

0.35

±

0.02 mm (0.0138

±

0.0008 in)

• If the measured value is not within standard, take
notes of the value in order to adjust the valve clear-
ance later on.

13) If necessary, adjust the valve clearance. <Ref.
to ME(H4DOTC)-29, ADJUSTMENT, Valve Clear-
ance.>

Valve Clearance

14) Further turn the crank pulley clockwise and
then measure the valve clearances again.

(1) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #2
cylinder exhaust valve and #3 cylinder intake
valve clearances.

(2) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #2
cylinder intake valve and #4 cylinder exhaust
valve clearances.

(3) Set the arrow mark on cam sprocket to the
position shown in the figure, and measure the #1
cylinder exhaust valve and #4 cylinder intake
valve clearances.

15) After inspection, install the related parts in the
reverse order of removal.

B: ADJUSTMENT

CAUTION:
Adjustment of valve clearance should be per-
formed while engine is cold.
1) Measure all valve clearances.
<Ref. to ME(H4DOTC)-28, INSPECTION, Valve
Clearance.>

NOTE:
Record each valve clearance after measurement.

2) Remove the camshaft. <Ref. to ME(H4DOTC)-
56, REMOVAL, Camshaft.>
3) Remove the valve lifter.
4) Measure the thickness of valve lifter using a mi-
crometer.

5) Select a valve lifter of suitable thickness from the
following table using the measured valve clearance
and valve lifter thickness.

Valve Clearance

6) Inspect all valves for clearance again at this
stage. If the valve clearance is not correct, repeat
the procedure over again from the first step. 
7) After inspection, install the related parts in the
reverse order of removal.
