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 IGNITION COILS AND HIGH±TENSION
CORDS (See page IG±7)
3. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the 6 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:
1,500 kPa (15.3 kgf/cm
2, 218 psi)
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.

mm hexagon wrench through the holes to keep the set-
ting position of the push rod.
(c) Release the press.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy±Conserving or ILSAC multi-
grade engine oil. SAE 5W±30 is the best choice for
your vehicle, for good fuel economy, and good start-
ing in cold weather.
2. CHECK ENGINE OIL LEVEL
After warming up the engine and then 5 minutes after the en-
gine stop, oil level should be between ºLº and ºFº of the dipstick.
If low, check for leakage and add oil up to ºFº mark.
NOTICE:

Do not fill with engine oil above the ºFº mark.

When inserting the oil dipstick, insert the curved tip
of the dipstick facing the same direction as the curve
of the guide.

If the dipstick gets caught while inserting it, do not
force it in. Reconfirm the direction of the dipstick.
3. REMOVE OIL PRESSURE SWITCH AND INSTALL OIL
PRESSURE GAUGE
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm245 ± 490 kPa (2.5 ± 5.0 kgf/cm2, 36 ± 71 psi)
6. REMOVE OIL PRESSURE GAUGE AND REINSTALL
OIL PRESSURE SWITCH
(a) Remove the oil pressure gauge.
(b) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833±00080, THREE BOND 1344, LOCTITE
242 or equivalent
(c) Reinstall the oil pressure switch.
7. START ENGINE AND CHECK FOR OIL LEAKS
