\j \ 11. INSPECT VALVE LIFTERS AND LIFTER BORES
\ \ (a) Using a caliper gauge, measure the lifter bore diame-
O \ C) ter of the cylinder head.
\ °' \ Lifter bore diameter:
k 4 .. 31.000 - 31.021 mm (1.220s — 1.2213 in.)

Using a micrometer, measure the lifter diameter.
Lifter diameter:
30.975 —- 30.985 mm (1.2195 — 1.2199 in.)
Subtract the lifter diameter measurement from the
lifter bore diameter measurement.
Standard oil clearance:
0.015 — 0.046 mm (0.0006 — 0.0018 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.
INSPECT MANIFOLDS
Intake Manifold:
Using a precision straight edge and feeler gauge, mea-
sure the surfaces contacting the cylinder head and
ACIS valve for warpage.
Maximum warpage:
0.30 mm (0.0118 in.)
If warpage is greater than maximum, replace the man-
ifold.
Exhaust Manifold:
Using a precision straight edge and feeler gauge, mea-
sure the surface contacting the cylinder head for war-
page.
Maximum warpage:
1.00 mm (0.0394 in.) "
If warpage is greater than maximum, replace the man-
ifold.
