CAUTION:
Apply new engine oil when installing the parts that specified to do so in the figure.
REMOVAL
1. Move harnesses on top surface and right side of rocker cover, and move them aside.
2. Remove ignition coil. Refer to EM-24, "
Removal and Installation" .
3. Disconnect PCV hoses on rocker cover side.
4. If necessary, remove PCV control valve.
5. If necessary, remove intake valve timing control solenoid valve and camshaft position sensor (PHASE).

2. Remove cylinder head front cover.
●Move harness secured to front surface beforehand.
3. Set No. 1 cylinder at TDC of its compression stroke.
a. Remove RH splash cover (integrated with undercover).
b. Rotate crankshaft pulley clockwise and align yellow paint mark
with timing indicator.

c. Confirm mating marks stamped on intake and exhaust sprockets
are located as shown.
●If not, rotate crankshaft pulley as shown and align them.
d. Referring to mating marks on intake and exhaust camshaft
sprockets, put paint mating marks on timing chain links.
4. Set intake camshaft sprocket to most advanced position.
CAUTION:
Removal/installation of intake camshaft sprocket is required to maintain most advanced position
because of following reasons. Therefore, follow procedure exactly.
●Sprocket and vane (camshaft in front) rotate and become
offset within specific angle range.
●When engine is stationary, vane is located at most
retarded position. Vane is fixed to sprocket by internal
lock pin. Therefore, it does not rotate.
●If camshaft sprocket mounting bolts are turned under
above circumstance, lock pin will be damaged by lateral
load (shear stress). It may cause non-standard operation.
●Set intake camshaft sprocket to most advanced position as
follows.
NOTE:
“Rotating direction” means direction viewed from engine front side.
CAUTION:
Do not remove chain tensioner before performing this step.
a. Using a wrench, hold hexagonal part so that intake camshaft
does not move.
b. Using an air gun, apply air pressure to intake valve timing con-
trol solenoid valve advanced side oil passage on top surface of
No. 1 camshaft bracket.
●Keep applying air pressure until step “d” is completed.
CAUTION:
●Be careful not to damage oil passage from interference of
air gun tip.
●Thoroughly wipe off oil before applying air pressure.
When applying air pressure, cover around air gun using a rag. Wear protective glasses if neces-
sary.

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).
