CAUTION:
●Apply new engine oil when installing the parts that specified to do so in the figure.
●Do not remove or disassembly parts unless instructed as shown in the figure.

"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
2. Disconnect harness for fuel injector, and move it aside.
3. Remove fuel hose.
CAUTION:
After removal, install blind plug to fuel hose to prevent the fuel from draining.
4. Remove fuel tube and injector assembly with the following pro-
cedure:
a. Loosen mounting bolts in reverse order shown in figure.
b. Pull out fuel injector/fuel tube assembly toward engine rear side.

3. Tighten mounting bolts in two steps in numerical order shown in
figure.
4. Install fuel feed hose.
CAUTION:
Install hose clamp avoiding interference with bulge, and
securely tighten it
5. Install remaining parts in the reverse order of removal.
INSPECTION AFTER INSTALLATION
●Check for fuel leakage with following procedure.
1. Turn ignition switch ON (do not start engine), and check connections for leakage by applying fuel pressure
to fuel piping.
2. Start engine, and re-check connections for fuel leakage by increasing engine speed. 1st step : 11.8 - 13.8 N·m (1.2 - 1.4 kg-m, 9 - 10 ft-lb)
2nd step : 17 - 23 N·m (1.7 - 2.4 kg-m, 13 - 17 ft-lb)

ROCKER COVER
6. Loosen bolts in reverse order shown in the figure.
7. If replacement is necessary, remove rocker cover oil seal using flat-head screwdriver.
CAUTION:
Be careful not to damage rocker cover.
INSTALLATION
1. Install rocker cover oil seal.
●Using drift with outer diameter 97 mm (3.82 in) and inner
diameter 83 mm (3.27 in) to 88 mm (3.46 in) (commercial ser-
vice tool), press oil seal in.
NOTE:
There are 2 types of oil seal. If oil seal with flat bottom surface is
pressed in, drift with any inner diameter can be used.
●Press oil seal in until it is flush with installation surface.
2. Install rocker cover in following steps.
a. Install gasket on top of No. 1 camshaft bracket.
●Position gasket aligning its shape with camshaft bracket side.
Align positioning stopper pin with hole on gasket, and install.
b. Install gasket (for circumference, square type) to installation
groove of rocker cover.
c. Apply liquid gasket to positions shown in figure, then install
rocker cover.

6. While holding hexagonal part of camshaft with a spanner, loosen
mounting bolts and remove intake and exhaust camshaft
sprockets.
CAUTION:
●Be careful that tool does not interfere with A/C piping.
●Avoid securing camshaft at other than hexagonal part
and loosening mounting bolts by utilizing tension of tim-
ing chain.
●Handle intake camshaft sprocket, taking care of following.
CAUTION:
●Secure stopper pin with vinyl tape to prevent detach-
ment.
●Avoid dropping it or subjecting it to impact.
●Do not disassemble. (Do not loosen 3 bolts on front sur-
face.)
NOTE:
If stopper pin is detached and lock pin is engaged at most retarded position during removal, recover as
follows.
a. Reinstall stopper pin to intake camshaft, and tighten intake camshaft sprocket mounting bolts so that air
does not leak.
CAUTION:
Tightening torque for mounting bolts must be minimum so that air does not leak, preventing dam-
age on internal lock pin.
b. Apply air pressure to disengage lock pin, and turn vane to most advanced position. (This step can be per-
formed with timing chain removed.)
c. Reinstall stopper pin.
d. Remove intakecamshaft sprocket from camshaft.
7. Remove camshaft brackets.
●Loosen mounting bolts in several steps in reverse order
shown in figure.
8. Remove camshaft.
CAUTION:
Be careful not to damage signal plate on rear end of intake
camshaft and crankshaft.
9. Remove adjusting shims and valve lifters.
●Identify installation position of each valve. Arrange removed
valves so they cannot be mixed up.
INSTALLATION
1. Install valve lifters and adjusting shims.
●Install them in their original positions.
●Install adjusting shim with its stamped mark facing downward (valve lifter side).

8. Remove stopper pin from intake camshaft sprocket.
9. Slowly turn crankshaft pulley clockwise to set intake camshaft
sprocket to most retarded position.
●Sprocket begins turning after crankshaft does. Once sprocket
starts turning, keep turning crankshaft until the vane (cam-
shaft) also begins turning. Most retarded position should now
be achieved.
●Most retarded position is confirmed when stopper pin groove
is at a clockwise offset from lock pin breathing groove.
●While turning crankshaft slightly more counterclockwise, con-
firm that lock pin is engaged when vane and sprocket turn
together.
10. Install cylinder head front cover.
●Apply liquid gasket (Use Genuine Liquid Gasket or equiva-
lent) continuously as shown in figure.
●Install it by aligning dowel pin on cylinder head.
11. Check and adjust valve clearance. Refer to EM-42, "
Va l v e
Clearance" .
12. From this step, install in the reverse order of removal.
