2. Rotate the reamer clockwise the full length of the
valve guide bore.
3. Continue to rotate the reamer clockwise while
removing it from the bore.
4. Thoroughly wash the guide in detergent and water
to remove any cutting residue.
5. Check the clearance with a valve (see page 6-391.

Install the intake manifold and tighten the nuts in a
crisscross pattern in two or three steps, beginning
with the inner nuts (see pages 9-2 thru 9-4).
. Always use a new intake manifold gasket.
Install the exhaust manifold and tighten the nuts in
a crisscross pattern in two or three steps, beginning
with the inner nut {see pages 9-6 and g-7).
. Always use a new exhaust manifold gasket.
Install the exhaust manifold bracket. lnstall the
exhaust pipe A and the bracket, then install the cover.

Install the head cover gasket in the groove of the
cylinder head cover, Seat the recesses for the
camshaft first, then work it into the groove around
the outside edges.
NOTE:
. Before installing the head cover gasket, thor-
oughly clean the seal and the groove.
. When installing, make sure the head cover gas-
ket is seated securely in the corners of the
recesses wath no gap.

Apply liquid gasket to the head cover gasket at the
four corners of the recesses.
NOTE:
. Use liquid gasket, Pan No. 08718 - 0001 or 08718- 0003.
. Check that the mating surfaces are clean and dry
before applying liquid gasket.
. 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.

Set the spark plug seal on the spark plug tube.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
NOTE:
. Before installing the cylinder head cover, clean
the cylinder head contacting surfaces with a
shop towel.
. Do not touch the parts where liquid gasket was
aDolied.
. Take care not to damage the spark plug seals
when installing the cylinder head cover,
. Visually check the spark plug seals for damage.
. Replace any washer that is damaged or deterio-
rated.
