GENERAL DESCRIPTION
3. ENABLE CONDITIONS
Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.
Time Needed for Diagnosis: 30 to 55 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.

Valve Clearance
MECHANICAL
10) Measure the clearance of intake valve and ex-
haust valve using thickness gauge (A).
NOTE:
•Measure it within the range of ±30° from speci-
fied position shown in the figure.
•Measure it in low lift cam for intake side.
•Insert a thickness gauge in a direction as hori-
zontal as possible with respect to the valve lifter.
Valve clearance
Intake:
0.20 +0.04 –0.06 mm (0.0079 +0.0016 –0.0024 in)
Exhaust:
0.35±0.05 mm (0.0138±0.0020 in)
•If the measured value is not within specification,
take notes of the value in order to adjust the valve
clearance later on.
11) If necessary, adjust the valve clearance. to ME(H6DO)-28, ADJUSTMENT, Valve Clear-
ance.>
12) Further turn the crank pulley clockwise and
then measure the valve clearances again.
13) After inspection, install the related parts in the
reverse order of removal.
B: ADJUSTMENT
1. INTAKE SIDE
CAUTION:
•Adjustment of valve clearance should be per-
formed while engine is cold.
•Do not wear gloves during removal and in-
stallation of valve lifter.
•Do not use the valve lifter which got high im-
pact due to drop etc.
•When installing the valve lifter, align the anti-
rotation of valve lifter with groove on cylinder
head, and then insert the valve lifter.
1) Measure all the valve clearances.
Clearance.>
NOTE:
Record each valve clearance after measurement.
2) Remove the camshaft. REMOVAL, Camshaft.>
3) Remove the valve lifter.
4) Remove the shim from valve lifter.
5) Check the thickness of the shim from the mark-
ings on the side of the shim that was removed.

face that mates with crankcase using a straight
edge (A) and thickness gauge (B).
Flatness:
Standard
0.02 mm (0.0008 in)
Standard height of cylinder head:
124±0.05 mm (4.88±0.0020 in)
NOTE:
Uneven torque for the cylinder head nuts can
cause warping. When reinstalling, pay special at-
tention to the torque so as to tighten evenly.
2. VALVE SEAT

correct the contact surfaces with a valve seat cutter
if they are defective or when valve guides are re-
placed.
Valve seat width W:
Intake
Standard
1.0 mm (0.039 in)
Exhaust
Standard
1.5 mm (0.059 in)
3. VALVE GUIDE
1) Check the clearance between valve guide and
stem. The clearance can be checked by measuring
respectively the outer diameter of valve stem and
inner diameter of valve guide with a micrometer.
Clearance between the valve guide and valve
stem:
Standard
Intake
0.030 — 0.057 mm (0.0012 — 0.0022 in)
Exhaust
0.040 — 0.067 mm (0.0016 — 0.0026 in)
2) If the clearance between valve guide and stem
exceeds the standard, replace the valve guide or
valve itself whichever shows greater amount of
wear or damaged and etc. See the following proce-
dure for valve guide replacement.
Valve guide inner diameter:
5.500 — 5.512 mm (0.2165 — 0.2170 in
Valve stem outer diameters:
Intake
5.455 — 5.470 mm (0.2148 — 0.2154 in)
Exhaust
5.445 — 5.460 mm (0.2144 — 0.2150 in)
(1) Place the cylinder head on ST1 with the
combustion chamber upward so that valve
guides fit the holes in ST1.
(2) Insert the ST2 into valve guide and press it
down to remove the valve guide.

E: INSPECTION
1. CYLINDER BLOCK
1) Visually check for cracks and damage. Especial-
ly, inspect the important parts using liquid pene-
trant tester.
2) Check the oil passages for clogging.
3) Inspect the crankcase surface that mates with
cylinder head for warping by using a straight edge.
Standard height of cylinder block:
202 mm (7.95 in)
2. CYLINDER AND PISTON
1) The cylinder bore size is stamped on the front
upper face of the cylinder block.
NOTE:
•Measurement should be performed at a temper-
ature of 20°C (68°F).
•Standard sized pistons are classified into two
grades, “A” and “B”. These grades should be used
as guide lines in selecting a standard piston.
Standard diameter:
A: 89.205 — 89.215 mm (3.5120 — 3.5124 in)
B: 89.195 — 89.205 mm (3.5116 — 3.5120 in)
2) How to measure the inner diameter of each cyl-
inder:
Measure the inner diameter of each cylinder in both
the thrust and piston pin directions at the heights as
shown in the figure, using a cylinder bore gauge.
NOTE:
Measurement should be performed at a tempera-
ture of 20°C (68°F).
Cylindricality:
Standard
0.030 mm (0.0012 in)
Out-of-roundness:
Standard
0.010 mm (0.0004 in)
3) When the piston is to be replaced due to general
or cylinder wear, determine a suitable sized piston
by measuring the piston clearance.

A: REPLACEMENT
1. REPLACEMENT OF ENGINE COOLANT
WARNING:
The radiator is of the pressurized type. Do not
attempt to open the radiator cap immediately
after the engine has been stopped.
1) Lift-up the vehicle.
2) Remove the under cover.
3) Place a container under drain pipe.
4) Remove the drain cock to drain engine coolant
into container.
5) For quick draining, open the radiator cap.
NOTE:
Be careful not to spill coolant on the floor.
6) Drain the coolant from reservoir tank.
7) Tighten the radiator drain cock securely after
draining coolant.
8) Pour cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
Cooling system conditioner (Part number:
SOA345001)
9) Fill engine coolant into the reservoir tank up to
“FULL” level.
Recommended engine coolant:
Refer to “RM” section. ANT, RECOMMENDED MATERIALS, Recom-
mended Materials.>
Coolant capacity (fill up to “FULL” level):
Approx. 7.4 2 (7.8 US qt, 6.5 Imp qt)
NOTE:
The SUBARU Genuine Coolant containing anti-
freeze and anti-rust agents is especially made for
SUBARU engine, which has an aluminum crank-
case. Always use SUBARU Genuine Coolant,
since other coolant may cause corrosion.
10) Close the radiator cap, and start the engine.
Race 5 to 6 times at 3,000 rpm or less, then stop
the engine. (Complete this operation within 40 sec-
onds.)
11) Wait for one minute after the engine stops, then
open the radiator cap. If the engine coolant level
drops, add engine coolant into radiator up to the fill-
er neck position.
12) Perform the procedures 10) and 11) again.
13) Install the radiator cap and reservoir tank cap
properly.
14) Start the engine and operate the heater at max-
imum hot position and the blower speed setting to
“LO”.
15) Run the engine at 2,000 rpm or less until radia-
tor fan starts and stops.
NOTE:
•Be careful with the engine coolant temperature
gauge to prevent overheating.
•If the radiator hose becomes harden by engine
coolant pressure at this time, air purge seems to be
mostly completed.
16) Stop the engine and wait until the engine cool-
ant temperature lowers to 30°C (86°F).
17) Open the radiator cap. If the engine coolant lev-
el drops, add engine coolant into the coolant filler
tank up to the filler neck position and the reservoir
tank to “FULL” level.
18) Install the radiator cap and reservoir tank cap
properly.
19) Set the heater setting to maximum hot position
and the blower speed setting to “LO” and start the
engine. Perform racing at less than 3,000 rpm. If
the flowing sound is heard from heater core, repeat
the procedures from step 10).
