FUEL CHECK VALVE
1. Blow air through connector on fuel tank side.
A considerable resistance should be felt and a portion of air
flow should be directed toward the EVAP canister side.
2. Blow air through connector on EVAP canister side.
Air flow should be smoothly directed toward fuel tank side.
3. If fuel check valve is suspected of not properly functioning in
steps 1 and 2 above, replace it.
Rollover valve operation (RHD models only)
Ensure that continuity of air passage does not exist when the
installed rollover valve is tilted to 90É or 180É.
FUEL TANK VACUUM RELIEF VALVE
1. Wipe clean valve housing.
2. Check valve opening pressure and vacuum.
Pressure:
15.3 - 20.0 kPa (0.1530 - 0.2001 bar, 0.156 - 0.204
kg/cm
2, 2.22 - 2.90 psi)
Vacuum:
þ6.0 to þ3.3 kPa (þ0.0598 to þ0.0333 bar, þ0.061 to
þ0.034 kg/cm
2, þ0.87 to þ0.48 psi)
3. If out of specification, replace fuel filler cap as an assembly.
CAUTION:
Use only a genuine fuel filler cap as a replacement.

REPLACING CAMSHAFT BUSHING
1. Using Tool, remove camshaft bushings from the engine.
Some bushings must be broken in order to remove.
2. Using Tool, install camshaft bushings as follows:
(1) Install camshaft bushings in the order of ``rear'', ``4th'', ``3rd'',
``2nd'' and ``front''. All bushings must be installed from the
front.
(2) Face the cutout upward and toward the front of the engine
during installation.
(3) Rear camshaft bushing
lAlign the cutout of rear bushing with knock pin of replacer bar
before installation.
lInsert rear bushing with replacer bar into the engine.
Install guide plate with bolt holes (on the ``TD'' mark side)
facing upper side of cylinder block. Tighten bolts.

CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than the specified value may cause damage
to the radiator.
Checking Fuel Lines
Inspect fuel lines and tank for improper attachment and for leaks,
cracks, damage, loose connections, chafing and deterioration.
If necessary, repair or replace malfunctioning parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Fuel Filter
WARNING:
Before removing fuel filter, release fuel pressure from fuel
line.
1. Remove fuse for fuel pump.
2. Start engine.
3. After engine stalls, crank engine two or three times to make
sure that fuel pressure is released.
4. Turn ignition switch OFF and install fuse for fuel pump.
5. Loosen fuel hose clamps.
6. Replace fuel filter.
lBe careful not to spill fuel or engine compartment. Place
a shop towel to absorb fuel.
lUse a high-pressure type fuel filter. Do not use a syn-
thetic resinous fuel filter.
lWhen tightening fuel hose clamps, refer to ``Checking
Fuel Lines'', MA-18.
