must replace the cylinder head.
- lf camshaft has not been replaced, first check
total runout with the camshaft supported on V-
blocks.

Valve lnstallation
When installing valves in cylinder head, coat valve
stems with oil before inserting into valve guides, and
make sure valves move up and down smoothly.
When valves and springs are in place, lightly tap the
end of each valve stem two or three times to ensure
proper seating of valve and valve keepers (use ham-
mer handle).
NOTE: Tap the valve stem only along its axis so you
do not bend the stem.
Valves, Valve Springs and
Valve SealsValve Guides
Valve Movement
Measure the guide-to-stem clearance with a dial indica-
tor while rocking the stem in the direction of normal
thrust (wobble method).

recheck using a new valve.
. lf measurement is now within the service limit,
reassemble using a new valve.
. lf measurement still exceeds limit, recheck using
alternate method below, then replace valve and
guide, if necessary.
NOTE: An alternate method ot checking guide to
stem clearance is to subtract the O.D. of the valve
stem. measured with a micrometer, from the l.D. ot
the valve guide, measured with an inside microme-
ter or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide.
The difference between the largest guide measure'
ment and the smallest stem measurement should
not exceed the service limit.

NOTE: For new valve guides only.
1. Coat both reamer and valve guide with cutting oil.
2, Rotate the reamer clockwise the full length of thevalve guide bore.
3. Continue to rotate the reamer clockwise whileremoving it from the bore.
4. Thoroughly wash the guide in detergent and waterto remove any cutting residue.
5. Check clearance with a valve (see page 6-70).
. Verify that the valve slides in the intake and ex-haust valve guides without exerting pressure.

NOTE:
. Use liquid gasket, Part No. 08718 - 0001.. Check that the mating surfaces are clean and dry
before applying liquid gasket.
a Do not install the parts if 20 minutes or more
have elapsed since applying liquid gasket.

Main Bearings
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 one strip of plastigage across each main iour-
nal.
NOTE: lf the engine is still in the car when you bolt
the main caD down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti-
gage further than just the torque on the cap bolt,
and give you an incorrect reading. Fot an accurate
reading, support the crank with a iack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (818C1
engine only) then torque the bolts.

column), and recheck the clearance.
CAUTION: Do not file, shim, or scrapo ihe bo.rings
