HINT:
As a large amount of exhaust gas enters, the engine will misfire
slightly.
(g) Remove the vacuum gauge, and reconnect the vacuum
hoses to the proper locations.
(h) Inspect the EGR valve.
(1) Apply vacuum directly to the EGR valve with the en-
gine idling.
(2) Check that the engine runs rough or dies.
(3) Reconnect the vacuum hoses to the proper loca-
tions.
HINT:
As exhaust gas is increasingly recirculated, the engine will start
to misfire.
(i) Remove the SST from the DLC1.
SST 09843±18020
2. INSPECT EGR VACUUM MODULATOR
(a) Disconnect the vacuum hoses from ports P, Q and R of
the EGR vacuum modulator.
(b) Block ports P and R with your finger.
(c) Blow air into port Q, and check that the air passes through
to the air filter side freely.
(d) Start the engine, and maintain speed at 2,500 rpm.
(e) Repeat the above test. Check that there is a strong resis-
tance to air flow.
(f) Reconnect the vacuum hoses to the proper locations.

(c) Check only the valves indicated as shown. Measure the
valve clearance. (See step (a))
4. ADJUST VALVE CLEARANCE
(a) Remove the adjusting shim.
(1) Turn the crankshaft so that the cam lobe of the cam-
shaft on the adjusting valve points upward.
(2) Position the notch of the valve lifter facing the spark
plug side.
(3) Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter. Re-
move SST (A).
SST 09248±55040 (09248±05410, 09248±05420)
HINT:
Apply SST (B) at slight angle on the side marked with º9º, at the
position shown in the illustration.
(4) Remove the adjusting shim with a small screwdriver
and magnetic finger.
(b) Determine the replacement adjusting shim size by follow-
ing the Formula or Charts:
(1) Using a micrometer, measure the thickness of the
removed shim.
(2) Calculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ........... Thickness of removed shim
A ........... Measured valve clearance
N ........... Thickness of new shim
Intake: N = T + (A ± 0.24 mm (0.009 in.))

INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND±HELD TESTER OR OBDII
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect a TOYOTA hand±held tester or OBDII scan tool
to the DLC3.
(c) Please refer to the TOYOTA hand±held tester or OBDII
scan tool operator's manual for further details.
3. CONNECT TIMING LIGHT TO ENGINE
4. INSPECT IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
HINT:
After engine rpm is kept at 1,000 ± 1,300 rpm for 5 seconds,
check that it returns to idle speed.
(b) Using a timing light, check the ignition timing.
Ignition timing: 8 ± 12° BTDC @ idle
(Transmission in neutral position)
(c) Remove the SST from the DLC1.
SST 09843±18020
5. FURTHER CHECK IGNITION TIMING
Ignition timing: 0 ± 10° BTDC @ idle
(Transmission in neutral position)
HINT:
The timing mark moves in a range between 0° and 10°.
6. DISCONNECT TIMING LIGHT FROM ENGINE

(e) Set SST and a dial indicator as shown in the illustration.
SST 09224±74010
HINT:
Make sure that the stem of the dial indicator is perpendicular to
the SST and that it is placed in the middle of the 3rd indentation.
(f) Lightly turn the No.1 balance shaft by hand until resis-
tance is felt, and measure the backlash.
HINT:

Turn the No.1 balance shaft 4 or 5 times to provide a
steady backlash reading.

To prevent excessive backlash due to thrust clearance,
measure the backlash while pressing on the rear of the
No.1 balance shaft.
Standard backlash (at punch mark A):
0.025 ± 0.065 mm (0.0010 ± 0.0026 in.)
NOTICE:
Do not turn the No.1 balance shaft strongly.
(g) Remove the dial indicator and SST.
(h) Turn the crankshaft clockwise to align the groove of the
No.2 housing with punch mark B.
(i) Set the dial indicator. (See step (e))
(j) Measure the backlash. (See step (f))
Standard backlash (at punch mark B):
0.025 ± 0.085 mm (0.0010 ± 0.0033 in.)
(k) Remove the dial indicator.
(l) Turn the crankshaft clockwise again to align the groove
of the No.2 housing with punch mark A.
(m) Set the dial indicator. (See step (e))
(n) Measure the backlash. (See step (f))
Standard backlash (at punch mark A):
0.025 ± 0.065 mm (0.0010 ± 0.0026 in.)
(o) Remove the dial indicator.

Minimum overall length:
Intake97.1 mm (3.823 in.)
Exhaust98.0 mm (3.858 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than the minimum length.
8. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:

If blue appears 360° around the face, the valve is
concentric. If not, replace the valve.

If blue appears 360° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.

Check that the seat contact is in the middle of the
valve face with the following width:
1.0 ± 1.4 mm (0.039 ± 0.055 in.)
