COMPRESSION PRESSURE
Inspection INFOID:0000000004784276
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-498, " Inspection " .
3. Remove ignition coil and spark plug from each cylinder. Refer to EM-46, " Exploded View " .
4. Connect an engine tachometer (not required in use of CONSULT-III).
5. Install a compression tester (B) with an adapter (commercial service tool) (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plug hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
6. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
CAUTION:
Always use fully a charged battery to obtain the specified engine speed.
• If the engine speed is out of the specified range, c heck battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
• If compression pressure is below minimum value, check valve clearances and parts associated with combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If some cylinder has 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, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Replace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low compression pressure and their compression remains low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
7. After inspection is completed, install removed parts.
8. Start the engine, and confirm that the engine runs smoothly.
9. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-112, " Description " . SBIA0533E
General Specification " .

• Handle ignition coil car efully and avoid impacts.
• Never disassemble.

3. Remove spark plug using suitable tool.
CAUTION:
Never drop or shock it.
4. Remove ground cable (RH).
5. Support the bottom surface of engine using a trans mission jack, and then remove the engine mounting
bracket and insulator (RH). Refer to EM-88, " Exploded View " .
6. Remove fuel tube protector.
7. Disconnect PCV valve hose from PCV valve.
8. Remove oil filler cap.
9. Remove rocker cover. • Loosen bolts in reverse order shown.
NOTE:
13 and 14 shown are used to tighten the fuel tube protector.
10. Remove rocker cover gasket from rocker cover.
11. Use scraper to remove all traces of liquid gasket from cylinder head and front cover.
CAUTION:
Never scratch or damage the mating su rface when cleaning off old liquid gasket.
INSPECTION AFTER REMOVAL CAUTION:
• Never drop or shock spark plug.
• Checking and adjusting spar k plug gap is not required
between change intervals.
• If spark plug tip is covered with carbon, a spark plug cleaner may be used. SMA806CA

1. Remove spark plug using suitable tool.
2. Remove valve lifter. • Identify installation positions, and store them without mixing them up.
3. Remove valve collet. • Compress valve spring with Tool (A). Remove valve collet witha magnet tool (B).
CAUTION:
Be careful not to damage valve lifter holes.
4. Remove valve spring retainer and valve spring.
5. Push valve stem to combustion chamber side, and remove valve. • Identify installation positions, and store them without mixing them up.
6. Remove valve oil seal using Tool (A).
7. Remove valve spring seat.
8. Remove valve seat, if necessary. • Bore out old seat until it collapses. Boring s hould not continue beyond the bottom face of the seat
recess in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Never bore excessively to prevent cylinder head from scratching.
9. Remove valve guide, if necessary.
a. To remove valve guide, heat cylinder head to 110 to 130 °C (230
to 266 °F) by soaking in heated oil (A).

d. Using suitable tool or valve seat grinder, finish seat to the speci-
fied dimensions. Refer to EM-119, " Cylinder Head " .
CAUTION:
When using the valve seat cutt er, firmly grip cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on with cutter or cu tting many different times may
result in stage valve seat.
