Install the timing belt (see page 6-12).
Adjust the valve clearance (see page 6-3).
lnstall the rubber seal in the groove of the cylinderhead cover. Seat the seal in the recesses for thecamshaft first, then work it into the groove aroundthe outside edges.
NOTE:
. Before installing the rubber seal, thoroughlyclean the seal and the groove.
. When installing, make sure the seal is seatedsecurely in the corners of the recesses with nogap.
RUEBER SEAL
18.Apply liquid gasket to the rubber seal at the eightcorners of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - OO01 or 08718- 0003.
. Check that the mating surfaces are clean and drybefore applying liquid gasket.. Do not installthe parts if 5 minutes or more naveelapsed since applying liquid gasket. Instead,reapply liquid gasket after removing old residue.. After assembly, wait at least 30 minutes beforefilling the engine with oil.
Apply liquid gasket tothe shaded areas.
