(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake 7.975-7.990 mm
(0.3140-0.3146 in.)
Exhaust 7.960-7.975 mm
(0.3134-0.3140 in.)
(c) Subtract the valve stem diameter measurement from
the guide bushing inside diameter measurement.
Standard oil clearance:
Intake 0.020-0.055 mm
(0.0008-0.0022 in.)
Exhaust 0.035-0.070 mm
(0.0014-0.0028 in.)
Maximum oil clearance:
Intake 0.08 mm (0.0031 in.)
Exhaust 0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve
and guide bushing.
10. IF NECESSARY, REPLACE VALVE GUIDE BUSHINGS
(a) Using SST and a hammer, tap out the guide bushing.
SST 09201-60011
(b) Using a caliper gauge, measure the bushing bore
diameter of the cylinder head.
(c) Select a new guide bushing (STD size or 0/S 0.05).
If the bushing bore diameter of the cylinder head is greater
than 13.025 mm (0.5128 in.), machine the bushing bore to
the following dimension:
Rebored cylinder head bushing bore dimension:
13.054-13.075 mm (0.5139-0.5148 in.)
If the bushing bore diameter of the cylinder head is greater
than 13.075 mm (0.5148 in.), replace the cylinder head.
