a) Apply new engine oil to the thrust portion and journal of the camshaft.
b) Place the No. 2 camshaft at a 90° angle of the timing mark (2 dot marks) on the cylinder head.
c) Apply MP grease to a new oil seal lip.
d) Install the oil seal to the camshaft.
NOTICE:
^
Do not turn over the oil seal lip.
^
Insert the oil seal until it stops.
e) Remove any old packing material from the contact surface.
