WARNING:
• Put a “CAUTION: FLAMMABLE”
sign in the workshop.
• Be sure to work in a well-ventila ted area and furnish workshop with a CO
2 fire extinguisher.
• Do not smoke while servicing fuel system. Keep open flames and sparks away from the work area.
CAUTION:
Do not remove or disassemble parts unless instructed.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

2. Remove camshaft sprocket (EXH) (1).
CAUTION:
• Hold the camshaft hexagonal pa rt (A), and then secure the
camshaft.
• Do not rotate crankshaft and camshaft separately, so as not to contact valve with piston.
NOTE:
The timing chain with the front cover installed is not disengaged
from the crankshaft sprocket and it is not dropped into the front
cover. Therefore, the timing chain tension holding device is not
necessary.
3. Turn the camshaft sprocket (INT) to the most advanced position. CAUTION:
Installation and removal of the camshaft sprocket (INT) must be done in the most advanced posi-
tion. Make sure to follow the procedure exactly.
• The sprocket (C) and vane (camshaft coupling) (B) are
designed to spin and move wi thin the range of a certain
angle.
• With the engine stopped and the vane in the most
retarded angle, it will not sp in because it is locked to the
sprocket side by the internal lock pin (A).
• If the camshaft sprocket bolts are turned in the situation
described above, the lock pi n will become damaged and
cause malfunctions because of the increased horizontal
load (cutting force) on the lock pin.
• Put the camshaft sprocket (INT) in the most advanced position:
a. Remove camshaft bracket (No. 1) (1). NOTE:
Timing chain is present only for illustration purposes. Timing
chain is to be removed during removal procedure.
• Loosen the bolts in several steps, and then remove them.
b. Apply the following air pressure to the No. 1 journal oil hole (A) of camshaft (INT) (1) shown using an air gun.
• Apply the air pressure into the oil hole on the second groove
from the front of camshaft thrust (B).
• Proceed all the way through step “e” with the air pressure on.
• Attach the rubber nozzle narrowed to the top of the air gun to prevent air leaks from the oil hole (A). Securely apply the air
pressure to the oil hole.
WARNING:
Eye protection should be worn as needed.
CAUTION:
• There are other oil holes in the side gr ooves. Do not use the incorrect oil holes.

c. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to
EM-60, "
Exploded View".
4. Crank engine, and then check that engine oil comes out from intake valve timing control solenoid valve hole (A). End crank
after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Prevent splashing by using a shop cloth to prevent injuryfrom splashing engine oil and so as to prevent engine oil contamination.
• Use a shop cloth to prevent engine oil from bein g splashed to engine and vehicle. Especially be
careful not to spill engine oil to rubber parts of drive belts, engine mounting insulator, etc. Wipe
engine oil off immediatel y if it is splashed.
5. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid valve oil hole of the cylinder head.
• Remove oil filter, and then clean it. Refer to LU-10, "
Removal and Installation".
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-5,
"Engine Lubrication System".
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary. Refer to LU-5, "
Engine Lubrication System".
7. After inspection, installation of components is in the reverse order of removal

2. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) force] or suitable tool.
WARNING:
Cylinder head contains heat; when working, wear protective
equipment to avoid getting burned.
3. Ream cylinder head valve guide hole with a suitable tool.
4. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
5. Using a suitable tool, press valve guide (1) from camshaft side of cylinder head (2) to dimensions as shown.
WARNING:
Cylinder head contains heat; when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide with a suitable tool.

VALVE SEAT CONTACT
• After confirming that the dimensions of valve guides
and valves are within the specifications, perform this
procedure.
• Apply prussian blue (or white lead) onto contacting surfac e of valve seat to check the condition of the valve
contact on the surface.
• Check if the contact area band is continuous all around the circum- ference.
• If not, grind to adjust valve fitting and check again. If the contacting surface still has “NG” conditions (B) even after the recheck,
replace valve seat. Refer to EM-78, "
Disassembly and Assembly".
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Prevent scoring cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.
• Be sure to ream in circles concentric to the valve guide center.This will enable valve seat to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Press-fit valve seats into cylinder head. WARNING:
Cylinder head contains heat; when working, wear protective equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.

WARNING:
• Position the vehicle on a flat and solid surface.
• Place chocks at front and back of rear wheels.
• Attach proper slingers and bolts described in PARTS CATALOG if engine is not already equipped.
CAUTION:
• Always be careful to work safely.
• Do not start working until exhaust system and coolant are cool enough.
• If items or work required are not covered by th e engine section, refer to the applicable sections.
• Always use the support poin t specified for lifting.
• Use either 2-pole lift type or separate type lift. If board-on type must be used, support the rear axle
jacking point with a transmission jack or similar to ol before starting work, in preparation for the
backward shift of center of gravity.
• For supporting points for lifting and j acking point at rear axle, refer to GI-29, "
2-Pole Lift".
