VALVE
SPRING
INSPECTION
Whenever valves have been removed for inspection,
reconditioning or replacement, valve springs should be tested. As an example the compression length of
the spring to be tested is
1-5/16
inch. Turn table of
Valve Spring Tester Tool C-647 until surface is in
line with the
1-5/16
inch mark on the threaded stud. Be sure the zero mark is to the front (Fig. 16). Place spring over stud on the table and lift compressing le
ver to set tone device. Pull on torque wrench until
ping is heard. Take reading on torque wrench at this instant. Multiply this reading by 2. 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.

(3) Install new seals on all valve guides. Install
valve springs and valve retainers.
(4) Compress valve springs with Valve Spring

lease tool. If valves and/or seats are ground, measure
the installed height of springs. Make sure the mea surement is taken from bottom of spring seat in cyl
inder head to the bottom surface of spring retainer. If
spacers are installed, measure from the top of spacer.
If height is greater than 42.86 mm (1-11/16 inches),
install a 1.587 mm (1/16 inch) spacer in head coun-
terbore. This should bring spring height back to nor mal 41.27 to 42.86 mm (1-5/8 to

HYDRAULIC
TAPPETS
Before disassembling any part of the engine to cor
rect tappet noise, check the oil pressure. If vehicle
has no oil pressure gauge, Install a reliable gauge at
the pressure sending unit. The pressure should be be
tween 207-552 kPa (30-80 psi) at 3,000 RPM. Check the oil level after the engine reaches normal
operating temperature. Allow 5 minutes to stabilize
oil level, check dipstick. The oil level in the pan should never be above the
FULL mark or below the ADD OIL mark on dipstick.
Either of these 2 conditions could be responsible for
noisy tappets.
OIL LEVEL
HIGH
If oil level Is above the FULL mark, It is possible
for the connecting rods to dip into the oil. With the engine running this condition could create foam in
the oil pan. Foam in oil pan would be fed to the hy
draulic tappets by the oil pump causing them to lose
length and allow valves to seat noisily.
LOW
Low oil level may allow oil pump to take in air.
When air is fed to the tappets, causes them to lose length and allows valves to seat noisily. Any leaks
on intake side of oil pump through which air can be
drawn will create the same tappet action. When tap
pet noise is due to aeration, it may be intermittent or constant, and usually more than 1 tappet will be
noisy. When oil level and leaks have been corrected, engine should be operated at fast idle for sufficient
time.
This allows all of the air inside of the tappets
to be bled out.
TAPPET NOISE DIAGNOSIS
(1) To determine source of tappet noise, operate en
gine at idle with cylinder head covers removed. (2) Feel each valve spring or rocker arm to detect
noisy tappet. The noisy tappet will cause the affected
spring and/or rocker arm to vibrate or feel rough in
operation.
Worn valve guides or cocked springs are some
times 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 appre ciably reduced, it can be assumed the noise Is in
the tappet. Inspect the rocker arm push rod sockets and
push
rod ends for wear.
(3) 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 or by the
plunger partially sticking in the tappet body cylin der. The tappet should be replaced. A heavy click is
caused by a tappet check valve not seating or by for
eign particles becoming wedged between the plunger and the tappet body. This will cause 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 inspec
tion and cleaning.
The valve train generates a noise very much like a
light tappet noise during normal operation. Care
must be taken to ensure that tappets are making the
noise. In general, if more than one tappet seems to
be noisy, its probably not the tappets.
REMOVAL
(1) Remove the air cleaner.
(2) Remove cylinder head cover.
(3) Remove rocker assembly and push rods. Iden
tify push rods to ensure Installation in original loca
tion.
(4) Remove Intake manifold.
(5) Remove yoke retainer and aligning yokes.
(6) Slide Hydraulic Tappet Remover/Installer Tool
C-4129-A through opening in cylinder head and seat
tool firmly in the head of tappet.
(7) Pull tappet out of bore with a twisting motion.
If all tappets are to be removed, identify tappets to ensure installation in original location.
(8) If the tappet or bore in cylinder block is scored,
scuffed, or shows signs of sticking, ream the bore to
next oversize. Replace with oversize tappet.
