Lifter / Lash Adjuster: Testing and Inspection

1. Using a caliper gauge measure the lifter bore diameter of the cylinder head.
Lifter bore diameter:
31.000-31.018 mm (1.2205-1.2213 in.)





2. Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.966-30.976 mm (1.2191-1.2195 in.)
3. Subtract the lifter diameter measurement from the lifter bore diameter measurement.
Standard oil clearance:
0.024-0.052 mm (0.0009-0.0020 in.)
Maximum oil clearance:
0.07 mm (0.0028 in.)

If the oil clearance is greater than maximum, replace the lifter. If necessary, replace the cylinder head.
