SPARK PLUG TUBE SEALS
The spark plug tube seals are located in the cylin-
der head cover (Fig. 43). These seals are pressed into
the cylinder head cover to seal the outside perimeter
of the spark plug tubes. If these seals show signs of
hardness and/or cracking, they should be replaced.
REMOVAL
(1) Remove cylinder head. Refer to procedure in
this section.
(2) Using an appropriate tool, carefully remove
spark plug tube seals. Care should be taken not to
damage cylinder head cover sealing surfaces.

NOTE: Inspect camshaft bearing journals for scor-
ing. Cylinder head must be flat within 0.1 mm (0.004
inch) (Fig. 56).
INSTALLATION
EXAMINING CYLINDER HEAD BOLTS
NOTE: The cylinder head bolts should be examined
BEFORE reuse. If the threads are necked down, the
bolt(s) should be replaced (Fig. 57).
Necking can be checked by holding a scale or
straight edge against the threads. If all the threads
do not contact the scale, the bolt(s) should be
replaced.CLEANING CYLINDER HEAD SEALING SURFACES
CAUTION: When cleaning cylinder head and cylin-
der block surfaces, DO NOT use a metal scraper.
Sealing surfaces could be cut or ground, resulting
in gasket leaks. Use only the cleaning methods
shown in (Fig. 58). If required, use a white (120 grit)
3M RolocYbristle disk on aluminum surfaces. A
yellow (80 grit) bristle disk can be used on cast iron
surfaces with care.
(1) Clean the cylinder head and cylinder block
sealing surfaces using a wood/plastic scraper. Apply
solvent or a commercially available gasket remover
to help soften the gasket residue. If additional clean-
ing is required, use a white (120 grit) 3M Rolocy
bristle disk and a drill motor to remove gasket resi-
due.

DISASSEMBLY AND ASSEMBLY
OIL PUMP
(1) To remove the relief valve, proceed as follows:
(2) Remove the threaded plug and gasket from the
oil pump (Fig. 116).
CAUTION: Oil pump pressure relief valve must be
installed as shown in (Fig. 116) or serious damage
may occur.
(3) Remove spring and relief valve (Fig. 116).
(4) Remove oil pump cover screws, and lift off
cover.
(5) Remove pump rotors.
(6) Wash all parts in a suitable solvent and inspect
carefully for damage or wear (Fig. 117).
VALVE SERVICE WITH THE CYLINDER HEAD
REMOVED
REMOVAL
(1) With cylinder head removed, compress valve
springs using Special Tool C-3422-B with Adaptor
6526.(2) Remove valve retaining locks, valve spring
retainers, valve stem seals and valve springs.
(3) Before removing valves,remove any burrs
from valve stem lock grooves to prevent dam-
age to the valve guides.Identify valves to insure
installation in original location.
VALVE INSPECTION
(1) Clean valves thoroughly and discard burned,
warped and cracked valves.
(2) Measure valve stems for wear. Measure stem
about 60 mm beneath the valve lock grooves.
(3) If valve stems are worn more than 0.05 mm
(0.002 in.), replace valve.
VALVE GUIDES
(1) Remove carbon and varnish deposits from
inside of valve guides with a reliable guide cleaner.
(2) Using a small hole gauge and a micrometer,
measure valve guides in 3 places top, middle and bot-
tom (Fig. 118). Replace guides if they are not within
specification. For specifications, refer to Engine Spec-
ifications in this section.
(3) Check valve guide height (Fig. 119).
TESTING VALVE SPRINGS
(1) Whenever valves have been removed for inspec-
tion, reconditioning or replacement, valve springs
should be tested Special Tool C-647. As an example,
the compression length of the spring to be tested is
33.34 mm (1-5/16 in.). Turn tool table until surface is
in line with the 33.34 mm (1-5/16 in.) mark on the
threaded stud and the zero mark on the front. Place
spring over stud on the table and lift compressing
lever to set tone device (Fig. 120). Pull on torque

a 0.762 mm (0.030 in.) spacer under the valve spring
seat to bring spring height back within specification.
(5) Install rocker arm shafts as previously
described in this section.
(6) Checking dry lash. Dry lash is the amount of
clearance that exists between the base circle of an
installed cam and the rocker arm roller when the
adjuster is drained of oil and completely collapsed.
Specified dry lash is 1.17 mm (0.046 in.) for intake
and 1.28 mm (0.050 in.) for exhaust. After performing
dry lash check, refill adjuster with oil and allow 10
minutes for adjuster(s) to bleed down before rotating
cam.
CLEANING AND INSPECTION
INTAKE MANIFOLD
CLEAN AND INSPECT
Check for:
²Inspect manifold for cracks or distortions.
²Check for torn or missing O-rings at the mating
surface of the manifold (Fig. 125).
EXHAUST MANIFOLD
CLEAN AND INSPECT
(1) Discard gasket and clean all gasket surfaces of
manifolds and cylinder head.
(2) Test manifold gasket surfaces for flatness with
straight edge. Surface must be flat within 0.15 mm
per 300 mm (.006 in. per foot) of manifold length.
(3) Inspect manifolds for cracks or distortion.
Replace manifold if necessary.
CYLINDER HEAD AND CAMSHAFT JOURNALS
CLEANING
Remove all gasket material from cylinder head. Be
careful not to gouge or scratch the aluminum head
sealing surface. Clean all engine oil passages.
To ensure engine gasket sealing, proper surface
preparation must be performed, especially with the
use of aluminum engine components and multi-layer
steel cylinder head gaskets.
Neveruse the following to clean aluminum gasket
surfaces:
²Metal scraper
²Abrasive pad or paper to clean cylinder block
and head
²High speed power tool with an abrasive pad or a
wire brush (Fig. 126)
NOTE: Multi-Layer Steel (MLS) head gaskets
require a scratch free sealing surface.
Only use the following for cleaning gasket surfaces:
²Solvent or a commercially available gasket
remover
²Plastic or wood scraper (Fig. 126)
²Drill motor with 3M RolocyBristle Disc (white
or yellow) (Fig. 126)
CAUTION: Excessive pressure or high RPM can
damage the sealing surfaces. The mild (white, 120
grit) bristle disc is recommended. If necessary, the
medium (yellow, 80 grit) bristle disc may be used
on cast iron surfaces with care.
