DIAGNOSIS AND TESTING (Continued)

NOTE: THE TIMING MARK ON THE SPROCKET,
THE (LOWER) NICKEL PLATED LINK, AND THE
ARROW ON THE SIDE OF THE GEAR COVER
SHOULD LINE UP WHEN THE BALANCE SHAFTS
ARE TIMED CORRECTLY.
(9) If the sprockets are timed correctly install the
balance shaft bolts and tighten to 28 N´m (250 in.
lbs.). A wood block placed between crankcase and
crankshaft counterbalance will prevent crankshaft
and gear rotation.
CHAIN TENSIONING
(1) Install chain tensioner loosely assembled.
(2) Position guide on double ended stud making
sure tab on the guide fits into slot on the gear cover.
Install and tighten nut/washer assembly to 12 N´m
(105 in. lbs.).
(3) Place a shim 1 mm (0.039 in.) thick x 70 mm
(2.75 in.) long or between tensioner and chain. Push
tensioner and shim up against the chain.Apply firm
pressure (5.5 to 6.6 lbs.) directly behind the
adjustment slot to take up all slack.Chain must
have shoe radius contact as shown in (Fig. 46).
(4) With the load applied, tighten top tensioner
bolt first, then bottom pivot bolt. Tighten bolts to 12
N´m (105 in. lbs.). Remove shim.
(5) Install carrier covers and tighten screws to 12
N´m (105 in. lbs.).HYDRAULIC LASH ADJUSTER
REMOVAL
(1) Remove cylinder head cover. Refer to procedure
outlined in this section.
(2) Remove cam follower assembly. Refer to cam-
shaft removal procedure outlined in this section to
gain access to cam followers and lash adjusters.
(3) Mark hydraulic lash adjusters for reassembly
in their original position. Lash adjusters are serviced
as an assembly.
INSTALLATION
(1) Install hydraulic lash adjuster assembly mak-
ing sure adjusters are at least partially full of oil.
This is indicated by little or no plunger travel when
the lash adjuster is depressed.
(2) Install cam follower assembly as previously
outlined in this section.
(3) Install camshaft as previously outlined in this
section.
(4) Install cylinder head cover as previously out-
lined in this section.
VALVE SPRINGS AND VALVE SEALS IN VEHICLE
REMOVAL
(1) Remove camshafts as previously outlined in
this section.
(2) Rotate crankshaft until piston is at TDC on
compression.
(3) With air hose attached to adapter tool
installed in spark plug hole, apply 90-120 psi air
pressure.
(4) Using Special Tool MD-998772-A with adapter
6779 (Fig. 47) compress valve springs and remove
valve locks.
(5) Remove valve spring.
(6) Remove valve stem seal by a using valve stem
seal tool.
INSTALLATION
(1) Install valve seal/valve spring seat assembly
(Fig. 48). Push the assembly down to seat it onto the
valve guide.
(2) Install valve spring and retainer, use Special
Tool MD-998772-A with adapter 6779 to compress
valve springs only enough to install locks (Fig. 47).
Correct alignment of tool is necessary to avoid nick-
ing valve stems.
(3) Remove air hose and install spark plugs.
(4) Install camshafts as previously outlined in this
section.
(5) Install cylinder head cover as previously out-
lined in this section.

NOTE: Worn valve guides or cocked springs are
sometimes mistaken for noisy tappets. If such is
the case, noise may be dampened by applying side
thrust on the valve spring. If noise is not apprecia-
bly reduced, it can be assumed the noise is in the
tappet. Inspect the rocker arm push rod sockets
and push rod ends for wear.
Valve tappet noise ranges from light noise to a
heavy click. A light noise is usually caused by exces-
sive leak-down around the unit plunger which will
necessitate replacing the tappet, or by the plunger
partially sticking in the tappet body cylinder. A heavy
click is caused either by a tappet check valve not
seating, or by foreign particles becoming wedged
between the plunger and the tappet body causing the
plunger to stick in the down position. This heavy
click will be accompanied by excessive clearance
between the valve stem and rocker arm as valve
closes. In either case, tappet assembly should be
removed for inspection and cleaning.
CHECKING ENGINE OIL PRESSURE
Check oil pressure using gauge at oil pressure
switch location. Oil pressure should be 34.47 kPa (5
psi.) at idle or 205 to 551 kPa (30 to 80 psi.) at 3000
RPM.
(1) Remove pressure sending unit and install oil
pressure gauge (Fig. 5).
CAUTION: If oil pressure is 0 at idle, do not run
engine at 3000 RPM.
(2) Warm engine at high idle until thermostat
opens.
SERVICE PROCEDURES
VALVE TIMING
(1) Remove front cylinder head cover and all 6
spark plugs.
(2) Rotate engine until the #2 piston is at TDC of
the compression stroke.
(3) Install a degree wheel on the crankshaft pulley.
(4) With proper adaptor, install a dial indicator
into #2 spark plug hole. Using the indicator find TDC
on the compression stroke.
(5) Position the degree wheel to zero.
(6) Remove dial indicator from spark plug hole.
(7) Place a 5.08 mm (0.200 in.) spacer between the
valve stem tip of #2 intake valve and rocker arm pad.
Allow tappet to bleed down to give a solid tappet
effect.
(8) Install a dial indicator so plunger contacts the
#2 intake valve spring retainer as nearly perpendic-
ular as possible. Zero the indicator.
(9) Rotate the engine clockwise until the intake
valve has lifted .254 mm (0.010 in.).
CAUTION: Do not turn crankshaft any further
clockwise as intake valve might bottom and result
in serious damage.
(10) Degree wheel should read 6 degrees BTDC to
6 degrees ATDC.
MEASURING TIMING CHAIN FOR STRETCH
(1) Place a scale next to timing chain so that any
movement of chain may be measured.
(2) Place a torque wrench and socket on camshaft
sprocket attaching bolt and apply torque in direction
of crankshaft rotation to take up slack; 41 N´m (30 ft.
lb.) with cylinder head installed or 20 N´m (15 ft. lb.)
with cylinder heads removed.With a torque
applied to the camshaft sprocket bolt, crank-
shaft should not be permitted to move. It may
be necessary to block crankshaft to prevent
rotation.
(3) Holding a scale even, with dimension reading
as shown (Fig. 6), along edge of chain links. Apply
torque in the reverse direction to 41 N´m (30 ft. lbs.)
with cylinder heads installed, or 20 N´m (15 ft. lbs.)
with cylinder heads removed. Check amount of chain
movement.
(4) Install a new timing chain, if its movement
exceeds 3.175 mm (1/8 inch).
(5) If chain is not satisfactory, refer to Timing
Chain Removal and Installation in this section.

(4) Remove upper intake manifold. Refer to Group
11, Exhaust System and Intake Manifolds for proce-
dure.
(5) Remove cylinder head covers and spark plugs.
(6) Remove electrical connector from ignition coils.
(7) Using suitable socket and flex handle at crank-
shaft pulley retaining screw, turn engine so the num-
ber 1 piston is at Top Dead Center on the
compression stroke.
(8) Remove rocker arms with rocker shaft and
install a dummy shaft. The rocker arms should not
be disturbed and left on shaft.
(9) With air hose attached to spark plug adapter
installed in number 1 spark plug hole, apply 90 to
100 psi air pressure (620.5 to 689 kPa). This is to
hold valves in place while servicing components.
(10) Using Tool C-4682 or equivalent, compress
valve spring and remove retainer valve locks and
valve spring.
(11) The intake valve stem seals should be pushed
firmly and squarely over the valve guide using the
valve stem as guide.Do Not Forceseal against top
of guide. When installing the valve retainer locks,
compress the springonly enoughto install the
locks.
CAUTION: Do not pinch seal between retainer and
top of valve guide.
(12) Follow the same procedure on the remaining 5
cylinders using the firing sequence 1-2-3-4-5-6.Make
sure piston in cylinder is at TDC on the valve
spring that is being covered.
(13) Remove spark plug adapter tool.
(14) Remove dummy shaft and install rocker shaft
assembly and tighten screws to 28 N´m (250 in. lbs.).
(15) Install cylinder head covers tighten screws to
14 N´m (120 in. lbs.) and electrical connector to igni-
tion coils.
(16) Install Intake Manifold. Refer to Group 11,
Exhaust System and Intake Manifold for procedure.
