Compression
MECHANICAL
2. Compression
A: INSPECTION
CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself during measure-
ment.
1) After warming-up the engine, turn the ignition
switch to OFF.
2) Make sure that the battery is fully charged.
3) Release the fuel pressure.
PRESSURE, PROCEDURE, Fuel.>
4) Remove all the spark plugs. 4, REMOVAL, Spark Plug.>
5) Check the starter motor for satisfactory perfor-
mance and operation.
6) Hold the compression gauge tightly against the
spark plug hole.
NOTE:
When using a screw-in type compression gauge,
the screw (put into cylinder head spark plug hole)
should be less than 18 mm (0.71 in) long.
7) Fully open the throttle valve.
8) Crank the engine by means of the starter motor,
and read the maximum value on the gauge when
the pointer is steady.
9) Perform at least two measurements per cylinder,
and make sure that the values are correct.
Compression (350 rpm and fully open throttle):
Standard:
1,275 — 1,471 kPa (13.0 — 1.50 kgf/cm2,
185 — 213 psi)
Service limit:
1,128 kPa (11.5 kgf/cm2, 164 psi)

Idle Speed
MECHANICAL
3. Idle Speed
A: INSPECTION
1) Before checking the idle speed, check the fol-
lowing item:
(1) Check the air cleaner element is free from
clogging, ignition timing is correct, spark plugs
are in good condition, and hoses are connected
properly.
(2) Check the malfunction indicator light does
not illuminate.
2) Idle the engine.
3) Stop the engine, and turn the ignition switch to
OFF.
4) Insert the cartridge to Subaru Select Monitor.
5) Connect the Subaru Select Monitor to data link
connector.
6) Turn the ignition switch to ON and Subaru Select
Monitor switch to ON.
7) Select {Each System Check} in Main Menu.
8) Select {Engine} in Selection Menu.
9) Select {Current Data Display & Save} in Engine
Control System Diagnosis.
10) Select {Data Display} in Data Display Menu.
11) Start the engine, and read the engine idle
speed.
12) Check the idle speed when no-loaded. (Head-
light, heater fan, rear defroster, radiator fan, A/C
and etc. are OFF)
Idle speed [No load and gears in neutral]:
650±50 rpm
13) Check the idle speed when loaded. (Turn the A/
C switch to “ON” and operate the compressor for at
least one minute before measurement.)
Idle speed [A/C ON and gears in neutral]:
770±50 rpm
NOTE:
Idle speed cannot be adjusted manually, because
the idle speed is automatically adjusted. If the pre-
scribed idle speed cannot be maintained, refer to
General On-board Diagnosis Table under “Engine
Control System”. sic Diagnostic Procedure.>

Ignition Timing
MECHANICAL
4. Ignition Timing
A: INSPECTION
CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself at measurement.
1) Before checking the ignition timing, check the
following item:
(1) Check the air cleaner element is free from
clogging, spark plugs are in good condition, and
hoses are connected properly.
(2) Check the malfunction indicator light does
not illuminate.
2) Idle the engine.
3) Stop the engine, and turn the ignition switch to
OFF.
4) Insert the cartridge to Subaru Select Monitor.
5) Connect the Subaru Select Monitor to data link
connector.
6) Turn the ignition switch to ON and Subaru Select
Monitor switch to ON.
7) Select {Each System Check} in Main Menu.
8) Select {Engine} in Selection Menu.
9) Select {Current Data Display & Save} in Engine
Control System Diagnosis.
10) Select {Data Display} in Data Display Menu.
11) Start the engine and check the ignition timing at
idle speed.
Ignition timing [BTDC/rpm]:
15°±8°/650
If the timing is not correct, check the ignition control
system. Refer to Engine Control System. EN(H6DO)(diag)-2, Basic Diagnostic Procedure.>

Intake Manifold Vacuum
MECHANICAL
5. Intake Manifold Vacuum
A: INSPECTION
1) Idle the engine.
2) Disconnect the brake vacuum hose from intake
manifold, and then install the vacuum gauge.
3) Keep the engine at idle speed and read the vac-
uum gauge indication.
By observing the gauge needle movement, internal
condition of the engine can be diagnosed as de-
scribed below.
Vacuum pressure (at idling, A/C OFF):
–60.0 kPa ( –450 mmHg, –17.72 inHg) or less

Diagnosis of engine condition by measurement of intake manifold vacuum
Va c u u m g a u g e i n d i c a t i o n Po s s i bl e e n g i n e c o n d i t i o n
1. Needle is steady but lower than normal position. This ten-
dency becomes more evident as engine temperature rises.
Air leakage around intake manifold gasket, disconnection or
damage of vacuum hose
2. Needle intermittently drops to position lower than normal
position.
Leakage around cylinder
3. Needle drops suddenly and intermittently from normal posi-
tion.
Sticky valve
4. When engine speed is gradually increased, needle begins to
vibrate rapidly at certain speed, and then vibration increases as
engine speed increases.
Weak or broken valve spr ings
5. Needle vibrates above and below normal position in narrow
range.
Defective ignition system or throttle chamber idle adjustment
