Adjust the shift cable (see section l4).. Adjust the throttle cable (see section 11).. Refill the engine with engine oil (see page g-4).
. Refill the transmission with oil or fluid (see sec-tion 13 or 14).
. Refill the radiator with engine coolant (see page
10_5).
. Bleed air from the cooling system with theheater valve open (see page l0-5).. Clean the battery posts and cable terminals withsandpaper, assemble them, then apply grease toDrevent corrosron.. Inspect for fuel leakage (see section 1l).After assembling fuel line pans, turn on the igni-tion switch (do not operate the starter) so thatthe fuel pump operates for approximately twoseconds and the fuel Iine pressurizes.
Repeat this operation two or three times, andcheck for fuel leakage at any point in the fuel line.

time, in a crisscross pattern, Then remove the
camshaft holder bolts from the cvlinder head.
Lift the camshafts out of the cylinder head. wipe
them clean, then inspect the lift ramps, Replace the
camshaft if any lobes are pitted, scored, or exces-
sively worn.
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in Dlace. Place aplastigage strip across each journal.
Install the camshaft holders. and torque the bolts tothe values and in the sequence shown on page 6-31.

Reaming
NOTE: For new valve guides only.
1. Coat the reamer and the valve guide with cutting oil.
2. Rotate the reamer clockwise the full length of the
valve guide bore.
Continue to rotate the reamer clockwise while
removing it from the bore.
Thoroughly wash the guide in detergent and water
to remove anY cutting residue.
Check clearance with a valve (see page 6-25).
Verify that the valves slide in the intake and exhaust
valve guides without exerting pressure.

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.

Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place a strip of plastigage across each main journal.
NOTE: lf the engine is still in the vehicle when you
bolt the main cap down to check clearance, the
weight of the crankshaft and flywheel will flatten
the plastigage further than just the torque on the
cap bolt, and give you an incorrect reading. For an
accurale reading, support the crank with a jack
under the counterweights and check only one bear-
Ing aI a Irme.
Reinstall the bearings and caps, then torque the
bolts,

lf the plastigage measures too wide or too narrow,(remove the engine if it's still in the vehicle),
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the same color code (select the color as shown on
the next page). and recheck the clearance, Do not
file, shim, or scrape the bearings or the caps to
adjust the clearance.
lf the plastjgage shows the clearance is still incor-
rect, try the ne)d larger or smaller bearing {the color
listed above or below that one), and check again. lf
the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace
the crankshaft and start over.
