6) Measure #1 cylinder valve clearance by using thickness
gauge.
CAUTION:
Insert the thickness gauge in as horizontal a direc-
tion as possible with respect to the valve stem end
face.

Apply engine oil to cylinder head at camshaft bearing loca-
tion before installing camshaft. Install camshaft so that
rocker arm is close to or in contact with“base circle”of cam
lobe.
CAUTION:
When camshafts are positioned as shown in figure,
camshafts need to be rotated at a minimum to align
with timing belt during installation.
Right-hand camshaft need not be rotated when set
at position shown in figure.
Left-hand intake camshaft: Rotate 80°clockwise.
Left-hand exhaust camshaft: Rotate 45°counter-clock-
wise.
