(e) Under the condition of (d), turn the valve timing controller
assembly to the advance angel side (the arrow marked
direction in the illustration) with your hand.
Standard: Must turn
HINT:
Depending on the air pressure, the valve timing controller as-
sembly will turn to the advance angle side without applying
force by hand. Also, under the condition that the pressure can
be hardly applied because of the air leakage from the port, there
may be the case that the lock pin could be hardly released.
(f)
Except the position where the lock pin meets at the maxi-
mum delay angle, let the valve timing controller assembly
turn back and forth and check the movable range and that
there is no disturbance.
Standard: Movable smoothly in the range about 30
°
(g) Turn the valve timing controller assembly with your hand
and lock it at the maximum delay angel position.

INSPECT VALVE LIFTERS AND LIFTER BORES
(a) Using a caliper gauge, measure the lifter bore diameter
of the cylinder head.
Lifter bore diameter:
31.000
− 31.025 mm (1.2205 − 1.2215 in.)
(b) Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.966
− 30.976 mm (1.2191 − 1.2195 in.)
(c) Subtract the lifter diameter measurement from the lifter
bore diameter measurement.
Standard oil clearance:
0.024
− 0.059 mm (0.0009 − 0.0023 in.)
Maximum oil clearance:
0.079 mm (0.0031 in.)
If the oil clearance is greater than maximum, replace the lifter.
If necessary, replace the cylinder head.
