direction.
• Do not reuse the removed gasket.
• Do not push in the gasket while installing the
tailpipe.
(c) Connect the 2 exhaust pipe supports, and install the
tailpipe.

INSPECTION
1. INSPECT VALVE LASH ADJUSTER ASSEMBLY
NOTICE:
• Keep the lash adjuster free from dirt and foreign
objects.
• Only use clean engine oil.
(a) Place the lash adjuster into a container full of engine
oil.
(b) Insert the SST's tip into the lash adjuster's plunger
and use the tip to press down on the checkball
inside the plunger.
SST 09276-75010
(c) Squeeze the SST and lash adjuster together to
move the plunger up and down 5 to 6 times.
(d) Check the movement of the plunger and bleed the
air.
OK:
Plunger moves up and down.
NOTICE:
When bleeding high-pressure air from the
compression chamber, make sure that the tip of
the SST is actually pressing the checkball as
shown in the illustration. If the checkball is not
pressed, air will not bleed.
(e) After bleeding the air, remove SST. Then try to
quickly and firmly press the plunger with a finger.
OK:
Plunger is very difficult to move.
If the result is not as specified, replace the lash
adjuster.
2. INSPECT CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(2) Using a dial indicator, measure the circle runout
at the center journal.
Maximum circle runout:
0.04 mm (0.0016 in.)
If the circle runout is greater than the
maximum, replace the camshaft.
HINT:
Check the oil clearance after replacing the
camshaft.

20. INSPECT INTAKE VALVE SEAT
(a) Apply a light coat of Prussian blue to the valve face.
(b) Lightly press the valve face against the valve seat.
(c) Check the valve face and valve seat by using the
following procedure.
(1) If Prussian blue appears around the entire
valve face, the valve face is concentric. If not,
replace the valve.
(2) If Prussian blue appears around the entire
valve seat, the guide and valve face are
concentric. If not, resurface the valve seat.
(3) Check that the valve seat contacts in the
middle of the valve face with the width between
1.1 and 1.5 mm (0.043 and 0.059 in.).
21. INSPECT EXHAUST VALVE SEAT
(a) Apply a light coat of Prussian blue to the valve face.
(b) Lightly press the valve face against the valve seat.
(c) Check the valve face and valve seat by using the
following procedure.
(1) If Prussian blue appears around the entire
valve face, the valve face is concentric. If not,
replace the valve.
(2) If Prussian blue appears around the entire
valve seat, the guide and valve face are
concentric. If not, resurface the valve seat.
(3) Check that the valve seat contacts in the
middle of the valve face with the width between
1.2 and 1.6 mm (0.047 and 0.063 in.).
22. INSPECT INNER COMPRESSION SPRING
(a) Using a vernier caliper, measure the free length of
the inner compression spring.
Standard free length:
45.46 mm (1.7898 in.)
If the free length is not as specified, replace the
spring.
(b) Using a steel square, measure the deviation of the
inner compression spring.
Maximum deviation:
1.0 mm (0.039 in.)
Maximum angle (reference):
2
If the deviation is greater than the maximum,
replace the spring.
