ENGINE - Service Adjustment Procedures11-15COMPRESSION PRESSURE CHECKMllFFAK
(1) Before checking compression, ensure that engine oil, the
starter motor, and battery are all in normal operating
condition.
(2) Start the engine and wait until engine coolant temperature
has risen to 80
- 95°C (176 - 205°F).
(3) Remove the all spark plugs.
(4) Crank the engine to remove any foreign objects in the
cylinders.
CautionCover the spark plug holes with shop towel, etc., in
order to keep expelled foreign objects from flying out,and keep away from the holes. When measuring
compression with water, oil, or fuel having entered the
cylinder through a crack, etc., these will come flying out
of the spark plug hole hot and fast, so be sure to take
the proper precautions.(5) Set the compression gauge to the spark plug hole.
(6) Holding the throttle valve full open, crank the engine and
measure compression.
Limit:
min. 980 kPa (139 psi)
min. 810 kPa (115 psi)(7) Perform (5) and (6) above for all the cylinders, ensuring that
compression pressure differential for each of the cylinders
is within the specified limit.
Limit: max.
100 kPa (14 psi)
(8) If a cylinder’s compression or pressure differential exceeds
the limit, add a small amount of oil through the spark plug
hole and repeat steps (5)
- (7).@If the addition of oil brings compression up, it is possible
that there is
harmf,uI friction between the piston ring
and cylinder wall.@If not compression up, valve seizure, poor valve seating,
or a compression leak from the gasket are all possible.

P.42-41.)@ Loosen the screw attaching the inside handle and slide

handle play.
FLOOR PAN INSPECTIONM42FIADA common result of body leaks is a soaked floor mat pad or
carpet, and it’s not unusual to find that the water is getting in
through the floor pan to some other low point
jn the body. It is
possible however, for water to enter higher up and run
downward to soak the mat.
Since a soaked mat should be removed for drying, it’s a good
way to start your check. Of course, mat removal means you’ll
have to take off door sill plates and pull out seats or seat
cushion. But, this gives you a clear field for action so you can
check body seam sealing and the plugs in the floor pan.
It’s usually not practical to water test for floor pan or
wheelhousing leaks unless a special underbody water spray
arrangement is available. As an alternate, the best way to
locate these leak points is to look for rusty seam edges or other
traces of leaks after the mats and cushions are removed.
Traces of mud are an indication that the water is coming in from
below.
