29. REMOVE OIL DIPSTICK AND GUIDE
(a) Remove the bolt holding the dipstick guide to the LH cylin-
der head.
(b) Pull out the dipstick guide together with the dipstick from
the No.1 oil pan.
(c) Remove the O±ring from the dipstick guide.
30. REMOVE CYLINDER HEAD COVERS
Remove the 8 bolts, cylinder head cover and gasket. Remove
the 2 cylinder head covers.
31. REMOVE CAMSHAFTS OF RH CYLINDER HEAD
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be held level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the intake camshaft.
(1) Align the timing marks (2 dot marks) 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.)

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, 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, 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.
33. DISASSEMBLE EXHAUST CAMSHAFTS
(a) Mount the hexagonal wrench head portion of the cam-
shaft in a vise.
NOTICE:
Be careful not to damage the camshaft.

4. INSPECT IGNITION COILS WITH IGNITERS
(a) Disconnect the high±tension cords from the ignition coils.
(b) Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the
high±tension terminals.

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 start-
ing in cold weather.
2. CHECK ENGINE OIL LEVEL
After warming up the engine and then 5 minutes after the en-
gine stop, oil level should be between ºLº and ºFº of the dipstick.
If low, check for leakage and add oil up to ºFº mark.
NOTICE:
Do not fill with engine oil above the ºFº mark.
When inserting the oil dipstick, insert the curved tip
of the dipstick facing the same direction as the curve
of the guide.
If the dipstick gets caught while inserting it, do not
force it in. Reconfirm the direction of the dipstick.
3. REMOVE OIL PRESSURE SWITCH AND INSTALL 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 rpm245 ± 490 kPa (2.5 ± 5.0 kgf/cm2, 36 ± 71 psi)
6. REMOVE OIL PRESSURE GAUGE AND REINSTALL
OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833±00080, THREE BOND 1344, LOCTITE
242 or equivalent
