INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-173, "
Removal and Installation".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke.
 Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front
cover.
 At the same time, make sure that both intake and exhaust cam
noses of No. 1 cylinder face inside ( ) as shown.
 If they do not face inside, rotate crankshaft pulley once more
(360 degrees) and align as shown.
b. Use a feeler gauge, measure the clearance between valve lifter
and camshaft.

c. Set No.4 cylinder at TDC of its compression stroke.
 Rotate crankshaft pulley (1) one revolution (360 degrees) and
align TDC mark (no paint) (B) to timing indicator (A) on front
cover.
 By referring to the figure, measure the valve clearance at loca-
tions marked “×” as shown in the table below [locations indi-
cated with black arrow ( )] with a feeler gauge.

3. If out of standard, perform adjustment procedure.
ADJUSTMENT
 Perform adjustment depending on selected head thickness of valve lifter.
1. Remove camshaft. Refer to EM-186, "
Removal and Installation".
2. Remove valve lifters at the locations that are out of the standard.

COMPRESSION PRESSURE
Checking Compression PressureINFOID:0000000001346452
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-1035, "
Inspection".
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea-
surement.
4. Remove engine cover. Refer to EM-156, "
Component".
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-145, "
Removal and Installation".
6. Connect an engine tachometer (not required in use of CONSULT-III).
7. Install a suitable compression tester with an adapter 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.
8. 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.
Compression pressure:
Unit: kPa (bar, kg/cm2 psi) /rpm
CAUTION:
Always use a fully charged battery to obtain the specified engine speed.
 If the engine speed is out of the specified range, check battery liquid for proper gravity. Check engine
speed again with normal battery gravity.

COMPRESSION PRESSURE
 If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, piston 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.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-781, "
Description".
