NOTE: Valve seats which are worn or burned can
be reworked, provided that correct angle and seat
width are maintained. Otherwise cylinder head must
be replaced.
(4) When seat is properly positioned the width of
intake seats should be 1.75 to 2.25 mm (0.69 to 0.088
in.) The width of the exhaust seats should be 1.50 to
2.00 mm (0.059 to 0.078 in.) (Fig. 19).
(5) Check the valve spring installed height after
refacing the valve and seat (Fig. 22).
TESTING VALVE SPRINGS
Whenever valves have been removed for inspection,
reconditioning or replacement, valve springs should
be tested (Fig. 21).As an example;the compression
length of the spring to be tested is 33.34 mm (1-5/16
inches). Turn table of Tool C-647 until surface is in
line with the 33.34 mm (1-5/16 inch) 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. Pull on torque wrench until
ping is heard. Take reading on torque wrench at this
instant. Multiply this reading by two. This will give
the spring load at test length. Fractional measure-
ments are indicated on the table for finer adjust-
ments. Refer to specifications to obtain specified
height and allowable tensions. Discard the springs
that do not meet specifications.
REMOVAL AND INSTALLATION
WIPER UNIT
When performing work on the upper engine.
Refer to Section 8K, Windshield Wipers and
Washers for removal of the Wiper Unit.
ENGINE MOUNTS
RIGHT SIDE MOUNT
REMOVAL
NOTE: Right mount should only be serviced as an
assembly to prevent noise, vibration and harshness
concerns.
(1) Remove the purge duty solenoid and wiring
harness from engine mount.
(2) Remove the two right engine mount insulator
vertical fasteners and loosen the horizontal fastener,
Do Notremove the large nut on the end of the core
from frame rail (Fig. 23).
(3) Remove the load on the engine motor mounts
by carefully supporting the engine and transmission
assembly with a floor jack.

(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

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.
(17) Connect negative cable to battery.
