PRECAUTIONS
4. Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.
5. Fill a bucket, such as a 20 (5-1/4 US gal, 4-3/8 Imp gal) oil can, with at least 10 (2-5/8 US gal, 2-1/4 lmp gal) of water.
Carefully place the already cut (serrated) valves into the water
one-at-a-time using a set of large tweezers and quickly move
away at least 2.7 m (9 ft).
6. The valves should be placed in a standing position as shown in the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-5/8 US gal, 2-1/4 lmp gal) amount of water. The com-
plete chemical reaction may take as long as 4 to 5 hours.
Remove the valves using a set of large tweezers after the chem-
ical reaction has stopped. Afterwards, valves can be disposed
as ordinary scrap.
Precaution for Assembly and InstallationINFOID:0000000009460458
• Use torque wrench to tighten bolts or nuts.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
follow the specifications.
• Always replace the old with a new gas ket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Bleed the air trapped within the system after draining the coolant.
• Before starting engine, apply fuel pressure to fuel li nes with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage or rattles.
Parts Requiring Angular TighteningINFOID:0000000009460459
• Use an angle wrench for the final tightening of the following engine parts.
- Cylinder head bolts
- Lower cylinder block bolts
- Connecting rod cap bolts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
• Do not use a torque value for final tightening.
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil.

• After removing the bolts and nuts, separate the mating surface and
remove the liquid gasket using Tool (A).
CAUTION:
Be careful not to damage the mating surfaces.
• 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.
CAUTION:
Do not damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the
gasket application surface, mounting bolts, and bolt holes.
2. Thoroughly clean the gasket application surface and the mating surface and remove adhering moisture, grease and foreign
materials.
3. Attach the liquid gasket tube to the tube presser. Use Genuine Silicone RTV Seal ant or equivalent. Refer to
GI-21, "Recommended Chemical Products and Sealants"
.
4. Apply the liquid gasket using suitable tool without breaks to the specified location.
• If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
• As for the bolt holes, normally apply the liquid gasket inside the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
• Within five minutes of the liquid gasket application, install the mating component.
• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill the engine with the specified oil and coolant. Refer to MA-11,
"FOR USA AND CANADA : Fluids and Lubricants".
CAUTION:
If there are more specific instruct ions in the procedures contained in this manual concerning liquid
gasket application, observe them. Tool Number (A): KV10111100 (J-37228)

COMPRESSION PRESSURE
COMPRESSION PRESSURE
Compression pressureINFOID:0000000009460475
CHECKING COMPRESSION PRESSURE
1. Warm up the engine to full operating temperature.
2. Release the fuel pressure. Refer to EC-182, "Work Procedure"
.
3. Remove the ignition coil and spark plug from each cylinder. Refer to EM-40, "Removal and Installation"
.
4. Connect engine tachometer (not required in use of CONSULT).
5. Disconnect the fuel injector harness connector to avoid any residual fuel injection during the measure- ment.
6. 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.
7. With the accelerator pedal fully depressed, turn the ignition switch to the “START” position to crank over
the engine. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform
these steps to check each cylinder.
Unit: kPa (kg/cm2, psi) / rpm
CAUTION:
Always use a fully charged battery to ob tain specified engine cranking speed.
• If the engine speed is out of specified rpm range, check the battery. Check engine speed again with a fully
charged battery.
• If compression pressure is below minimum value, check valve clearances and parts associated with com- bustion chamber (valve, valve seat, piston, piston ri ng, cylinder bore, cylinder head, cylinder head gasket).
After the checking, measure compression pressure again.
• If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole of the cylinder to re-check it for compression.
• If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the pis- ton rings and replace if necessary.
• If the compression pressure remains at low level des pite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
