a. Insert Tool (A) between the lower oil pan and the upper oil pan.
CAUTION:
• Be careful not to damage the mating surface.
• Do not insert a screwdriver or similar tool, this will dam-
age the mating surfaces.
b. In areas where the cutter is difficult to use, use a plastic hammer to lightly tap (1) the cutter where the liquid gasket is applied. Use
a plastic hammer to slide (2) the cutter by tapping on the side.
4. If re-installing the original lower oil pan, remove the old liquid gasket from the mating surfaces using a scraper.
• Also remove the old liquid gasket from mating surface of the upper oil pan.
• Remove the old liquid gasket from the bolt holes and threads.
CAUTION:
Do not scratch or damage the mating surf aces when cleaning off the old liquid gasket.
INSPECTION AFTER REMOVAL
Clean oil strainer if any object is attached.
INSTALLATION
1. Apply a continuous bead of liquid gasket to the lower oil pan.
• Use Genuine Silicone RTV Sealant, or equivalent. Refer to GI-
21, "Recommended Chemical Products and Sealants".
• Be sure the liquid gasket is 4.5 - 5.5 mm (0.177 - 0.217 in) wide.
• Installation must be done within 5 minutes after applying liquid gasket.
2. Install the lower oil pan. Tighten the lower oil pan bolts in order as shown.
• Wait at least 30 minutes before refilling the engine with oil.
INSPECTION AFTER INSTALLATION
• Start the engine and check for leaks. Refer to LU-25, "Inspection".
• Inspect the engine oil level. Refer to LU-25, "Inspection"
.

REMOVAL
WARNING:
• Do not remove the oil pan until the exhaust system and cooling syst em have completely cooled off.
• When removing the front and rear engine through bolt s and nuts, lift the engine up slightly for safety.
For engine slingers, refer to EM-220, "Removal and Installation"

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.
• To avoid the danger of being scalded, do no t drain engine coolant when engine is hot.
1. Remove engine room cover. Refer to EM-143, "Removal and Installation"
.
2. Release the fuel pressure. Refer to EC-687, "Work Procedure"
.

b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector (1) to fuel tube until top spool (2) is
completely inside quick connector, and 2nd level spool (3)
exposes right below quick connector.
CAUTION:
• Do not reuse O-ring.
• Hold (A) position as shown when inserting fuel tube into quick connector.
• Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
• Insert until you hear a “click” sound and actually feel the engagement.
• To avoid misidentification of enga gement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Check it is completely engaged (connected) so that it does
not come out from fuel tube.
e. Install quick connector cap (3) to quick connector.
• Install quick connector cap with arrow (A) on surface facing indirection of quick connector (fuel feed hose side).
CAUTION:
If quick connector cap cannot be installed smoothly, quick
connector may have not been installed correctly. Check
connection again.
f. Secure fuel feed hose to clamp of quick connector cap.
8. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections as follows:
1. Apply fuel pressure to fuel lines by turning i gnition switch ON (with engine stopped). Then check for fuel
leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to EC-
682, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-683, "Work Procedure"
.

CAMSHAFT
• Using inside micrometer, measure diameter of valve lifter bore of
cylinder head. Refer to EM-247, "Camshaft"
EM-247, "Camshaft".
• If out of the specified range, replace the cylinder head assembly.
Calculation of Valve Lifter Clearance
• (Valve lifter clearance) = (hole diameter for valve li fter) – (outer diameter of valve lifter) Refer to EM-247,
"Camshaft".
• If out of specified range, replace either or both valve lifter and cylinder head assembly.
Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
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.
7. After inspection, installation of the remaining components is in the reverse order of removal.

CYLINDER HEAD
1. To remove valve guide, heat cylinder head to 110
° to 130 °C
(230 ° to 266 °F) by soaking in heated oil.
WARNING:
Cylinder head contains heat. When working, wear protective
equipment to avoid getting burned.
2. Drive out the valve guide with a press [under a 20 kN (2.2 US ton) pressure] or hammer and suitable tool.
3. Ream cylinder head valve guide hole.
4. Heat cylinder head to 110 ° to 130 °C (230 ° to 266 °F) by soaking
in heated oil and press new valve guide from camshaft side into
the cylinder head to the dimensions as shown.
WARNING:
Cylinder head contains heat . When working, wear protec-
tive equipment to avo id getting burned.

5. Using a valve guide reamer, apply a reamer finish to the valve
guide.
VALVE SEAT CONTACT
• After confirming that the dimensions of valve guides and valves are
within specifications, perform this procedure.
• Apply prussian blue onto contacting surface 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 fitti ng and check again. If the contacting
surface still has NG conditions even after the re-check, replace
valve seat.
VALVE SEAT REPLACEMENT
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess in cylinder head. Set
the machine depth stop to ensure this.
2. Ream cylinder head recess for service valve seat.
Be sure to ream in circles co ncentric to the valve guide cen-
ter.
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.
WARNING:
Cylinder head contains heat . When working, wear protec-
tive equipment to avo id getting burned.
4. Press fit valve seat until it seats on the bottom.
5. Cut or grind valve seat using suitable t ool to the specified dimensions. Refer to EM-249, "Cylinder Head"
.
6. After cutting, lap valve seat with abrasive compound.
7. Check valve seating condition. Intake and exhaust
