c. Slowly turn intake camshaft in direction A (counterclockwise:
intake manifold side).
●Perform while applying air pressure.
CAUTION:
Be careful not to dislocate camshaft retaining spanner.
d. During above step, operating click (a sound indicating internal
lock pin is disengaged) is heard from inside of intake camshaft
sprocket. After hearing it, slowly turn intake camshaft in direction
B (clockwise: exhaust manifold side), and set to most advanced
position.
●Perform while applying air pressure.
●When vane rotates solely against sprocket, lock pin is disengaged even if operating click is not heard.
●If lock pin is not disengaged, apply vibration by jiggling the camshaft with a spanner.
●If lock pin is not disengaged with above step, hit intake camshaft in front by using plastic hammer.
e. The following status indicates that most advanced position is
achieved: vane starts rotating on its own, then sprocket also
starts rotating when camshaft is turned. When above status is
achieved, this step is complete.
●Most advanced position is confirmed when stopper pin groove
and lock pin breathing groove are aligned.
f. Stop air, insert stopper pin [approximately 3 mm (0.12 in) dia.,
length of inserted part is approximately 15 mm (0.59 in)] into
pinhole on camshaft sprocket to fix most advanced position.
NOTE:
In the figure, an Allen wrench [a/f 2.5 mm (0.091 in), short part:
approximately 20 mm (0.79 in), long part: approximately 50 mm
(1.97 in)] is used for stopper pin as an example.
CAUTION:
Load (spring reaction force) is not applied to stopper pin.
Pin is easily detached. Therefore, secure it with vinyl tape to
prevent detachment.
5. Remove chain tensioner.
●Remove in the following order.
a. Press plate down, and release stopper tab.
b. Insert plunger into tensioner body until it stops.
c. Secure plate by passing stopper pin (such as a hard wire)
through plate hole and body hole. (Plunger is also secured.)
d. Remove mounting bolts, and remove chain tensioner.

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.

Valve Lifter Hole Diameter
●Using inside micrometer, measure diameter of valve lifter hole of
cylinder head.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (hole diameter of valve lifter) – (outer diam-
eter of valve lifter).
●When out of specified range, referring to each specification of outer and inner diameter, replace either or
both valve lifter and cylinder head.
Valve ClearanceEBS00LQC
INSPECTION
●The following procedure is applicable when: Components related to camshafts or valves are removed,
installed, or replaced. Drivability concerns (poor starting, poor idling, noise) are caused by valve clearance
aging.
1. Warm up engine, and stop.
2. Remove RH splash cover (integrated with undercover).
3. Remove rocker cover. Refer to EM-29, "
ROCKER COVER" .
4. Turn crankshaft pulley clockwise (viewed from front) to align yel-
low paint with timing indicator.
5. At this point, confirm that both intake and exhaust cam noses on
No. 1 cylinder face outward. (No. 1 cylinder is at TDC of its com-
pression stroke.)
●If not, turn crankshaft pulley more.
NOTE:
Or, valves to be checked when No. 4 cylinder is at TDC of its
compression stroke can be checked first following step 8.
6. Referring to figure, measure valve clearances of valves with × in
table below using a thickness gauge.Standard (Intake and exhaust)
: 30.000 - 30.021 mm (1.1811 - 1.1819 in) dia.
Standard (Intake and exhaust)
: 0.025 - 0.061 mm (0.0010 - 0.0024 in)

●Thickness of a new valve lifter can be identified by stamp
marks on the reverse side (inside the cylinder).
Stamp mark 696 indicates 6.96 mm (0.2740 in) in thickness.
Available thickness of valve lifter: 26 sizes with range 6.96 to 7.46 mm (0.2740 to 0.2937 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory).
5. Install the selected valve lifter.
6. Install camshaft.
7. Manually turn crankshaft pulley a few turns.
8. Check that valve clearances for cold engine are within specifications by referring to the specified values.
9. After completing the repair, check valve clearances again with the specifications for warmed engine. Make
sure the values are within specifications.
Valve clearance:
Unit: mm (in)
*: Approximately 20°C (68°F)
ADJUSTMENT (SHIM TYPE)
●Remove adjusting shim for valves with incorrect valve clearance by following the procedure below:
1. Using a rag, completely wipe off engine oil from surroundings of adjusting shim.
2. When removing adjusting shim from a cam, turn crankshaft
clockwise (viewed from front) to make cam nose face straight
up.
3. Turn valve lifter and adjusting shim to removal direction.
●Using a slotted screwdriver with extra-thin tip, turn valve lifter
cutout in direction shown by the arrow.
4. Using camshaft pliers (special service tool), pinch camshaft.
Turn tool up in direction shown by the arrow with camshaft being
a fulcrum. This will push down adjusting shim to allow valve
spring to be compressed.
CAUTION:
●Be careful not to damage camshaft and cylinder head.
●Be careful not to damage surroundings of valve lifter.
