B: INSTALLATION

1) Apply engine oil to camshaft journals, and install
the camshaft.
2) Install the camshaft cap.

(1) Apply liquid gasket sparingly to back side of
front camshaft cap as shown in the figure.

CAUTION:
Do not apply liquid gasket excessively. Apply-
ing excessively may cause excess gasket to
flow toward cam journal, resulting in engine
seizure.

NOTE:
Install within 5 minutes after applying liquid gasket.

Liquid gasket:

or equivalent

Applying liquid gasket diameter:

2.0

r

0.5 mm (0.079

r

0.020 in)

(2) Apply engine oil to cap bearing surface, and
install the cap to camshaft.
(3) Tighten the rocker cover bolts in the numer-
ical order as shown in the figure.

Tightening torque:

(1) — (12): 16 N·m (1.6 kgf-m, 11.8 ft-lb)
(13) — (16): 9.75 N·m (1.0 kgf-m, 7.2 ft-lb)

3) Install the plugs.

Tightening torque:

60 N·m (6.1 kgf-m, 44.3 ft-lb)

4) Install the rocker cover.

(1) Install the rocker cover gasket to the rocker
cover.

NOTE:
Use a new rocker cover gasket.

(2) Apply liquid gasket sparingly to the mating
surface of cylinder head and rocker cover as
shown in the figure.

CAUTION:
Do not apply liquid gasket excessively. Applying
excessively may cause excess gasket to flow to-
ward cam journal, resulting in engine seizure.

NOTE:
Install within 5 minutes after applying liquid gasket.

C: INSPECTION

1) Measure the bend of camshaft. Repair or re-
place if bended.

Service limit:

0.020 mm (0.00079 in)

2) Check the journal for damage and wear. Re-
place if faulty.
3) Check the cutout portion used for camshaft sen-
sor for damage. Replace if faulty.
4) Measure the outside diameter of camshaft jour-
nal. If the journal diameter is not within specifica-
tion, check the oil clearance.

5) Measurement of the camshaft journal oil clear-
ance:

(1) Clean the camshaft cap and cylinder head
camshaft journal.
(2) Place the camshaft on the cylinder head.
(Do not attach the valve rockers.)
(3) Place a plastigauge across each camshaft
journals.
(4) Install the camshaft cap.

NOTE:
Do not turn the camshaft.

(5) Remove the camshaft cap.
