1) Camshaft installation
Apply engine oil to cylinder head at camshaft bear-
ing location before installing camshaft. Install cam-
shaft so that rocker arm is close to or in contact
with ªbase circleº of cam lobe.
CAUTION:
IWhen camshafts are positioned as shown in
figure, camshafts need to be rotated at a mini-
mum to align with timing belt during installa-
tion.
IRight-hand camshaft need not be rotated
when set at position shown in figure.
Left-hand intake camshaft: Rotate 80É clock-
wise.
Left-hand exhaust camshaft: Rotate 45É
counter-clockwise.

2) Camshaft cap installation
(1) Apply fluid packing sparingly to cap mating
surface.
CAUTION:
Do not apply fluid packing excessively. Failure
to do so may cause excess packing to come
out and flow toward oil seal, resulting in oil
leaks.
Fluid packing:

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