Coat the valve stems with oil. Insert the valves into
the valve guides.
Check that the valves move up and down smoothly.
Install the spring seats on the cylinder head.
Install the valve seals using the special tool.

Check that the mating surfaces are clean and dry.
Apply liquid gasket, part No. 08718 - 0001 or 08718- 0003, to the head cover gasket at the eight corners
of the recesses.
NOTE:
. Do not install the parts if five minutes or more
have elapsed since applying liquid gasket.
Instead, reapply liquid gasket after removing old
residue.
. After assembly. wait at least 30 minutes before
filling the engine with oil.
Apply liquid gasket tothe shaded areas.
Hold the head cover gasket in the groove by placing
your fingers on the camshaft holder contacting sur-
faces (top of the semicirclesl.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
Inspect the cover washers. Replace any washer that
is damaged or dete(iorated.
