COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. REMOVE HIGH−TENSION CORDS WITH IGNITION
COILS (See page IG−1)
3. REMOVE SPARK PLUGS
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,200 kPa (12.2 kgf/cm
2, 174 psi) or more
Minimum pressure:
1,000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi) or less
(e) If the cylinder compression in 1 or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS

NOTICE:
”Cold” and ”Hot” in the following sentences express the temperature of the coils themselves. ”Cold” is from
−10°C (14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to 100°C (212°F).
1. INSPECT IGNITOR AND SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cords from the spark plugs.
(2) Remove the spark plugs.
(3) Install the spark plugs to each high−tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 1
− 2 seconds at a time.
If the spark does not occur, perform the test as follows:
