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

the head cover gasket.
Inspect the cover washers. Replace any washer that

Oil Filter
The numbers in the middle of the API Service label tell
you the oil's SAE viscosity or weighl. Select the oil for
your vehicle according to this chart:
Ambient Temperature
100 F
40c-30 -20 -10
An oil with a viscosity of 5 W - 30 is preferred for
improved fuel economy and year-round protection in
the vehicle. You may use a 10 W - 30 oil if the climate in
your area is limited to the temperature range shown on
the chart.
