A: SPECIFICATION
Recommended oil:
Those with an API standard SM “Energy Conserving” logo.
ILSAC standard GF-4 ”Star burst mark” label on the container
CAUTION:
When replenishing oil, it does not matter if the oil to be added is a different brand from that in the en-
gine; however, use oil having the API standard and SAE viscosity No. designated by SUBARU.
NOTE:
If the vehicle is used in areas with very high temperatures or for other heavy duty applications, the following
viscosity oils must be used: API standard: SM or SL
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50

Cylinder Head
MECHANICAL
3) Measure the flatness of the cylinder head sur-
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
Inspect the intake and exhaust valve seats, and
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.
