General Description
C: CAUTION
Wear working clothing, including a cap, protec-
tive goggles and protective shoes during operation.
Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro-
tect them from dust or dirt.
Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
Be careful not to burn yourself, because each
part in the vehicle is hot after running.
Be sure to tighten bolts and nuts to the specified
torque.
Place shop jacks or rigid racks at the specified
points.
Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground
cable from battery.
All parts should be thoroughly cleaned, paying
special attention to the engine oil passages, pis-
tons and bearings. Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
All removed parts, if to be reused, should be re-
installed in the original positions and directions.
Bolts, nuts and washers should be replaced with
new ones as required.
Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
Remove or install engine in an area where chain
hoists, lifting devices, etc. are available for ready
use.
Be sure not to damage coated surfaces of body
panels with tools, or not to stain seats and windows
with coolant or oil. Place a cover over fenders, as
required, for protection.
Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.

Valve Clearance
8. Valve Clearance
A: INSPECTION
NOTE:
Inspection and adjustment of the valve clearance
should be performed while engine is cold.
1) Set the vehicle on a lift.
2) Lift-up the vehicle.
3) Remove the under cover.
4) Lower the vehicle.
5) Disconnect the ground cable from battery.
6) Remove the belt cover (LH).
7) When inspecting the #1 and #3 cylinders:
(1) Disconnect the spark plug cords from spark
plugs RH side.
(2) Disconnect the PCV hose from rocker cover
(RH).
(3) Remove the bolts, and then remove the
rocker cover (RH).
8) When inspecting the #2 and #4 cylinders:
(1) Disconnect the spark plug cords from spark
plugs (LH Side)
(2) Disconnect the PCV hose from rocker cover
(LH).
(3) Remove the bolts, and then remove the
rocker cover (LH).
9) Set the #1 cylinder piston to top dead center of
compression stroke by rotating crank pulley clock-
wise using a socket wrench.NOTE:
When arrow mark (A) on the cam sprocket (LH)
comes exactly to the top, #1 cylinder piston is
brought to the top dead center of compression
stroke.
10) Measure the #1 cylinder valve clearance by us-
ing thickness gauge.
CAUTION:
Insert the thickness gauge (A) in as horizon-
tal a direction as possible with respect to the
valve stem end face.
Measure the exhaust valve clearances while
lifting-up the vehicle.
Valve clearance (Standard):
Intake;
0.20
±0.04 mm (0.0079±0.0016 in)
Exhaust;
0.25
±0.04 mm (0.0098±0.0016 in)
11) If necessary, adjust the valve clearance.
ance.>
12) Similar to measurement procedures used for
#1 cylinder, measure the #2, #3 and #4 cylinder
valve clearances.
NOTE:
Be sure to set the cylinder pistons to their re-
spective top dead centers on compression stroke
before measuring valve clearances.

Valve Clearance
To set the #3, #2 and #4 cylinder pistons to their
top dead centers on compression stroke, turn the
crank pulley clockwise 90° at a time starting with ar-
row mark on cam sprocket (LH) facing up.
13) After inspection, install the related parts in the
reverse order of removal.

Resonator chamber;
33 N
⋅m (3.4 kgf-m, 25 ft-lb)
B: ADJUSTMENT
NOTE:
Adjustment of the valve clearance should be per-
formed while engine is cold.
1) Set the #1 cylinder piston to top dead center of
compression stroke by rotating crank pulley clock-
wise using socket wrench.
NOTE:
When arrow mark (A) on the cam sprocket (LH)
comes exactly to the top, #1 cylinder piston is
brought to the top dead center of compression
stroke.2) Adjust the #1 cylinder valve clearance.
(1) Loosen the valve rocker nut and screw.
(2) Place suitable thickness gauge.
(3) While noting the valve clearance, tighten the
valve rocker adjusting screw.
(4) When specified valve clearance is obtained,
tighten the valve rocker nut.
Tightening torque:
10 N
⋅m (1.0 kgf-m, 7.2 ft-lb)
CAUTION:
Insert the thickness gauge in as horizontally
as possible with respect to the valve stem end
face.
Adjust the exhaust valve clearances while
lifting up the vehicle.
Valve clearance:
Intake:
0.20
±0.04 mm (0.0079±0.0016 in)
Exhaust:
0.25
±0.04 mm (0.0098±0.0016 in)
3) Ensure the valve clearances are within specifi-
cations.
4) Turn the crankshaft two complete rotations until
#1 cylinder piston is again set to the top dead cen-
ter of compression stroke.
5) Ensure the valve clearances are within specifi-
cations. If necessary, readjust the valve clearanc-
es.
6) Similar to adjustment procedures used for #1
cylinder, adjust the #2, #3 and #4 cylinder valve
clearances.
