(2) Secure the exhaust camshaft sub-gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 - 20 mm (0.63 - 0.79 in.)
HINT:
When removing the camshaft, mark certain that the torsional
spring force of the sub-gear has been eliminated by the above
operation.
(3) Uniformly loosen and remove the 10 bearing cap
bolts in several passes and in the sequence shown.
(4) Remove the 5 bearing caps and intake camshaft.
(b) Remove the exhaust camshaft.
(1) Uniformly loosen and remove the 10 bearing cap
bolts in several passes and in the sequence shown.
(2) Remove the 5 bearing caps, oil seal and exhaust
camshaft.
30. REMOVE CAMSHAFTS OF LH CYLINDER HEAD
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept leveled while it is being installed. If
the camshaft is not kept leveled, the portion of the cylinder
head receiving the shaft thrust may crack or be damaged,
causing the camshaft to seize or break. To avoid this, the
following steps should be carried out.

(a) Remove the intake camshaft.
(1) Align the timing marks (1 dot mark) of the camshaft
drive and driven gears by turning the camshaft with
a wrench.
(2) Secure the exhaust camshaft sub-gear to the main
gear with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 - 20 mm (0.63 - 0.79 in.)
HINT:
When removing the camshaft, make sure that the torsional
spring force of the sub-gear has been eliminated by the above
operation.
(b) Uniformly loosen and remove the 10 bearing cap bolts in
several passes and in the sequence shown.
(c) Remove the 5 bearing caps and intake camshaft.
(d) Remove the exhaust camshaft.
(1) Uniformly loosen and remove the 10 bearing cap
bolts in several passes and in the sequence shown.
(2) Remove the 5 bearing caps, oil seal and exhaust
camshaft.
HINT:

Arrange the camshafts in the correct order.

Arrange the bearing caps in the correct order.

2. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on a used
spark plug.

Spark plugs should be replaced every 193,000 km
(120,000 miles).
(a) Remove the 6 ignition coils (with igniters) (See page
IG-5).
(b) Inspect the electrode.

Using a megger (insulation resistance meter), mea-
sure the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (d).
HINT:
If a megger is not available, these simple method of inspection
provides fairly accurate results.

Simple Method:

Quickly race the engine to 4,000 rpm 5 times.

Remove the spark plug (See step (c)).

Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (d)

Reinstall the spark plug (See step (g)).
(c) Using a 16 mm plug wrench, remove the 6 spark plugs.
(d) Visually check the spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSO madeSK20R11
NGK madeIFR6A11
(e) Inspect the electrode gaps.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip. Never attempt
to adjust the gap on the used plug.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy-Conserving or ILSAC multi-
grade engine oil.
SAE 5W - 30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
2. CHECK ENGINE OIL LEVEL
After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the low level and full level
marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL
OIL PRESSURE GAUGE
(a) Using SST, remove the oil pressure switch.
SST 09816-30010
(b) Install the oil pressure gauge.
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm294 - 539 kPa (3.0 - 5.5 kgf/cm2, 43 - 78 psi)
