VALVE ADJUSTING
CAUTION:
Adjust valve clearance while engine is cold.
NOTE:
• Perform adjustment by selecting the correct head thicknes s of the valve lifter (adjusting shims are not used).
• The specified valve lifter thickness is the dimension at normal temperatures. Ignore dimensional differences
caused by temperature. Use spec ifications for hot engine condition to confirm valve clearances.
1. Remove the camshaft. Refer to EM-194, "Removal and Installation"
.
2. Remove the valve lifter that was measur ed as being outside the standard specifications.
3. Measure the center thickness of the removed lifter with a micrometer, as shown.
4. Use the equation below to calculate the replacement valve lifter thickness.
Valve lifter thickness calculation equation: t = t1 + (C1 - C2)
t = thickness of the replacement lifter
t1 = thickness of the removed lifter
C1 = measured valve clearance
C2 = standard valve clearance
• The thickness of the new valve lifter can be identified by the
stamp mark on the reverse side (inside the lifter).
• Available thickness of the valve lifter (factory setting):
7.88 - 8.40 mm (0.3102 - 0.3307 in), in 0.02 mm (0.0008 in)
increments, in 27 sizes (intake / exhaust). Refer to EM-249,
"Cylinder Head".
5. Install the selected replacement valve lifter.
6. Install the camshaft. Refer to EM-194, "Removal and Installation"
.
7. Rotate the crankshaft a few turns by hand.
8. Confirm that the valve clear ances are within specification.
9. After the engine has been run to full operating temperat ure, confirm that the valve clearances are within
specification.
* Approximately 80 °C (176 °F)

COMPRESSION PRESSURE
COMPRESSION PRESSURE
On-Vehicle ServiceINFOID:0000000009460536
CHECKING COMPRESSION PRESSURE
1. Run the engine until it reaches normal operating temperature.
2. Turn the ignition switch to OFF.
3. Release fuel pressure and leave t he fuel pump electrically disconnected.
Refer to EC-687, "Work Procedure"
.
4. Remove all six spark plugs. Refer to EM-132, "Removal and Installation"
.
5. Install the compression tester with the adapter into the spark plug hole. • Use compression tester whose end (a) (rubber portion) is
smaller than 20 mm (0.79 in) in diameter. Otherwise, it may be
caught by cylinder head during removal.
6. Depress accelerator pedal fully to keep the electric throttle control actuator butterfly-valve wide open to
maximize air intake flow.
7. Crank the engine and record the highest gauge indication.
8. Repeat the measurement on each cylinder (steps 5 - 7). NOTE:
Always use a fully charged battery to obtain specified engine speed.
Unit: kPa (kg/cm2, psi)/rpm
9. If compression in one or more cylinders is low:
a. Pour a small amount of engine oil into cylinders through the spark plug holes.
b. Retest compression (steps 5 - 8).
• If adding oil helps raise compression pressure, then the piston rings may be worn or damaged. If so, replace piston rings after checking piston.
• If the pressure stays low, a valve may be sticking or is seating improperly. Inspect and repair the valve and/
or valve seat. Refer to EM-212, "Inspection After Disassembly"
. If the valve and/or valve seat is damaged
replace as necessary.
• If compression stays low in two or more cylinders that are next to each other:
- The cylinder head gasket may be leaking.
- Both cylinders may have valve component damage. Inspect and repair as necessary.

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.

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"
.
