INSPECT VALVE LIFTERS AND LIFTER BORES

Using a caliper gauge, measure the lifter bore diameter
(a)
of the cylinder head.
lifter bore diameter:
31 .000 - 31 .025 mm (1 .2205 - 1 .2215 1n.)
Using a micrometer, measure the lifter diameter.
(b)
Lifter diameter:
30.966 - 30.976 mm (1.2191 - 1 .2195 in.)
Subtract the lifter diameter measurement from the lifter
(c)
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 litter.
If necessary, replace the cylinder head.
