CYLINDER HEAD SET BOLT
Using a vernier caliper, measure the diameter of the elongated thread at the measuring point.
Measuring point:
Intake side bolt 94 mm (3.70 in.)
Exhaust side bolt 89 mm (3.50 in.)
Standard outside diameter 10.85 to 11.00 mm (0.427 to 0.433 in.)
Minimum outside diameter 10.6 mm (0.417 in.)
If the diameter is less than the minimum, replace the cylinder head bolt.
HINT: If a visual check reveals no excessively thin areas, check the center of the bolt (see illustration) and find the area that has the lowest diameter.
