Camshaft

17) Loosen the exhaust camshaft cap bolts equal-
ly, a little at a time in alphabetical sequence shown
in the figure.

18) Remove the oil flow control solenoid valve as-
sembly, intake camshaft cap and camshaft.
19) Remove the exhaust camshaft caps and cam-
shaft.

NOTE:
Arrange the camshaft caps in order so that they
can be installed in their original positions.
20) Similarly, remove the camshafts (RH) and re-
lated parts.

B: INSTALLATION

1) Camshaft installation:
Apply engine oil to the cylinder head at camshaft
bearing location before installing the camshaft. In-
stall the camshaft so that each valve is close to or in
contact with “base circle” of cam lobe.

NOTE:
• When the camshafts are positioned as shown in
the figure, camshafts need to be rotated at a mini-
mum to align with the timing belt during installation.
• Camshaft RH need not be rotated when set at
the position shown in the figure.
Intake camshaft (LH):
Rotate 80

° clockwise.

Exhaust camshaft (LH):
Rotate 45

° counterclockwise.

Camshaft

2) Camshaft cap and oil flow control solenoid valve
assembly installation:

(1) Apply small amount of liquid gasket to the
cap mating surface.

NOTE:
Do not apply liquid gasket excessively. Otherwise,
the excessive liquid gasket may come out and flow
toward oil seal, resulting in oil leaks.

Liquid gasket:

THREE BOND 1215 (Part No. 004403007) or 
equivalent

(2) Apply engine oil to the cap bearing surface,
and install the cap on camshaft as shown by
identification mark.
(3) Gradually tighten the camshaft cap and oil
control valve assembly in at least two stages in
alphabetical sequence shown in the figure, and
then tighten to the specified torque.

Tightening torque:

T1: 20 N

⋅

m (2.0 kgf-m, 14.8 ft-lb)

T2: 9.75 N

⋅

m (1.0 kgf-m, 7.2 ft-lb)

(4) After tightening the camshaft cap, ensure
the camshaft rotates only slightly while holding it
at “base circle”.

3) Install the camshaft position sensor on exhaust
side.

Tightening torque:

6.4 N

⋅

m (0.65 kgf-m, 4.7 ft-lb)

4) Camshaft oil seal installation:
Apply grease to the new oil seal lips and press onto
the front end of camshaft by using ST1 and ST2.

NOTE:
Use a new oil seal.
