Removal
ldentify the valves and valve springs as they are
removed so that each item can be reinstalled in its origi-
nal Dosition.
1. Using an appropriate-sized socket and plastic mallet.
lightly tap the valve retainer to loosen the valve keeP
ers before installing the valve spring compressor'
2. Install the spring compressor. Compress the spring
and remove the valve keeper.

Valve Seats
Reconditioning
lf the guides are worn (see page 6-25), replace them (seepage e25) before reconditioning the valve seats.
1. Renew the valve seats in the cylinder head using avalve seat cutter.
Carefully cut a 45o seat, removing only enoughmaterialto ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30. cutterand the lower edge of the seat with the 60" cutter.Check width of seat and adjust acco.dingly.
Make one more very light pass with the 45o cutter toremove any possible burrs caused bv the other cut-ters.
Valve Seat Width (lntake and Exhaust):
Standard {N.w}: 1.25 - 1.55 mm (0.049 - 0.051 in)Servica Limit: 2.0 mm (0.08 in)

5. After resurfacing the seat, inspect for even valve
seating: Apply Prussian Blue compound to the valve
face, and insert the valve in its original location in
the head, then lift it and snap it closed against the
seat several times.

The actual valve seating surface, as shown by the
blue compound, should be centered on the seat.. lf it is too high (closer to the valve stem), you
must make a second cut with the 60" cutter tomove it down, then one more cut with the 45"
cutter to restore seat width.
. lf it is too low (closer to the valve edge), you
must make a second cut with the 30. cutter tomove it up, then one more cut with the 45. cutter
to restore seat width.

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.

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.
