INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If the valve does not fall smoothly, replace the valve. If neces-
sary, replace the oil pump assembly.
2. INSPECT ROTOR BODY CIEARANCE
Using a thickness gauge, measure the clearance between the
driven rotor and pump body.
Standard body clearance:
0.10 − 0.18 mm (0.0039 − 0.0069 in.)
Maximum body clearance:
0.30 mm (0.0118 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
3. INSPECT ROTOR TIP CLEARANCE
Using a thickness gauge, measure the clearance between the
drive and driven rotor tips.
Standard tip clearance:
0.11 − 0.24 mm (0.0043 − 0.0094 in.)
Maximum tip clearance:
0.35 mm (0.0138 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
4. INSPECT ROTOR SIDE CLEARANCE
Using a thickness gauge and precision straight edge, measure
the clearance between the rotors and precision straight edge.
Standard side clearance:
0.03 − 0.09 mm (0.0012 − 0.0035 in.)
Maximum side clearance:
0.15 mm (0.0059 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.

NOTICE:
”Cold” and ”Hot” in the following sentences express the temperature of the coils themselves. ”Cold” is from
−10°C (14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to 100°C (212°F).
1. INSPECT IGNITOR AND SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cords from the spark plugs.
(2) Remove the spark plugs.
(3) Install the spark plugs to each high−tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 1
− 2 seconds at a time.
If the spark does not occur, perform the test as follows:

(i) Using an ohmmeter, measure the resistance.
Maximum resistance: 25 kΩ per cord
If the resistance is greater than the maximum, check the termi-
nals.
If necessary, replace the high−tension cord.
(j) Connect the high−tension cords to the distributor cap. As-
semble the holder and grommet.
HINT:
Connect the high−tension cords to the distributor cap as shown
in the illustration.
NOTICE:
Check that the holder is correctly installed to the grommet
and distributor cap as shown in the illustration.
(k) Check that the lock claw of the holder is engaged by lightly
pulling the holder.
(l) Connect the high−tension cords to the spark plugs.
Secure the high−tension cords with the clamps as shown
in the illustration.
(m) Install the intake air connector.
(n) Install the air cleaner cap and MAF meter assembly.
3. INSPECT SPARK PLUGS
(a) Disconnect the high−tension cords from the spark plugs.
(b) Using a 16 mm plug wrench, remove the spark plug.
