1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to
EC-496, "
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 plughole 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, check 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-106, "
Description".

The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.
1. Make sure that crankshaft key points are aligned.
NOTE:
*: There are two outer grooves in camshaft spro cket (INT). The wider one is a matching mark.
2. If the timing chain tension guide (front cover si de) is removed, install it to the front cover.
CAUTION:
Check the joint condition by sound or feeling.
3. Install crankshaft sprocket (2), oil pump sprocket (3) and oil pump drive chain (1).
• Install it by aligning matching marks on each sprocket and oil
pump drive chain.
• If these matching marks are not aligned, rotate the oil pump
shaft slightly to correct the position.

speed again with normal battery gravity.
• If compression pressure is below minimum val ue, 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 one cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
