CAUTION
Iridium plugs are used. Use care not to damage the iridium
tips of the plugs. Do not adjust the spark plug gap.
1. Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission level.
Therefore, they should be replaced periodically with new
ones.

2. The new plugs should be checked for the proper gap.
Spark plug gap: 0.7 − 0.8 mm (0.028 − 0.031 inch)
3. Install the spark plugs and tighten to 25 ± 4 N⋅ m (18 ± 3
ft-lb).

1. Before inspection, check that the engine oil, starter and
battery are normal. Also, set the vehicle in the following
condition:
• Engine coolant temperature: 80 − 95° C (176 − 203° F)
• Lights, and all accessories: OFF
• Transaxle: P range
2. Remove all of the ignition coils.
3. Remove the rocker cover.
4. Turn the crankshaft clockwise until the notch on the pulley is
lined up with "T" mark on the timing indicator.

5. Move the rocker arms on the No.1 and No.4 cylinders up
and down by hand to determine which cylinder has its piston
at the top dead center on the compression stroke.
If both intake and exhaust valve rocker arms have a valve
lash, the piston in the cylinder corresponding to these rocker
arms is at the top dead center on the compression stroke.
6. Valve clearance inspection and adjustment can be
performed on rocker arms indicated by white arrow mark
when the No.1 cylinder piston is at the top dead center on
the compression stroke, and on rocker arms indicated by
black arrow mark when the No.4 cylinder piston is at the top
dead center on the compression stroke.
7. Measure the valve clearance.
If the valve clearance is not as specified, loosen the rocker
arm lock nut and adjust the clearance using a thickness
gauge while turning the adjusting screw.
Standard value (hot engine):
Intake valve: 0.20 mm (0.008 inch)
Exhaust valve: 0.30 mm (0.012 inch)
