Make sure that, as the bolts are tightened, the clear-
ance between the camshaft journal and the cylinder
head journal decreases evenly at three places. If not,
loosen the bolts by reversing the illustrated numerical
sequence, and then repeat step (4) above.
(5) Tighten each bolt to the specified torque in the
sequence explained in step (4) .
2) Installation of intake camshaft
Each intake and exhaust camshaft gear has match
marks at two places. Accordingly, if the match marks
are incorrectly aligned, the cam timing will be mis-
aligned by 180° between the inside and exhaust side .
To avoid this, be sure to use the following method
when assembling the camshafts.
(1) Apply a coat of engine oil to the hydraulic lash
adjuster surface and insert hydraulic lash adjusters .
(2) Apply a coat of engine oil to the camshaft jour-
nals .
(3) Align the intake camshaft match mark with the
match mark of the exhaust camshaft which is already
installed . In this case, make sure that the notch on the
front end of the intake camshaft and that of the
exhaust camshaft are facing the same direction (fac-
ing upward) . After that, install the three camshaft
caps at the specified positions, and fully hand-tighten
the bolts .
Be sure to hold the camshaft with one hand so that it
will not drop while installing the camshaft caps .

(4) See the rear side of the camshaft gears, and make
