(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 - 0.050 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.
20. INSPECT AIR INTAKE CHAMBER
Using a precision straight edge and feeler gauge, measure the
surfaces contacting the intake manifold for warpage.
Maximum warpage: 0.15 mm (0.0059 in.)
If warpage is greater than maximum, replace the chamber.
A02166
21. INSPECT INTAKE MANIFOLD
Using a precision straight edge and feeler gauge, measure the
surfaces contacting the cylinder head and air intake chamber
for warpage.
Maximum warpage: 0.15 mm (0.0059 in.)
If warpage is greater than maximum, replace the manifold.

22. INSPECT EXHAUST MANIFOLD
Using a precision straight edge and feeler gauge, measure the
surfaces contacting the cylinder head for warpage.
Maximum warpage: 0.80 mm (0.0315 in.)
If warpage is greater than maximum, replace the manifold.

23. INSPECT CYLINDER HEAD BOLTS
Using a vernier caliper, measure the thread outside diameter of
the bolt.
Standard outside diameter:
10.8 - 11.0 mm (0.425 - 0.433 in.)
Minimum outside diameter: 10.7 mm (0.421 in.)
If the diameter is less than minimum, replace the bolt.
