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.
