SURFACE VARIATION
CYLINDER HEAD SET BOLT
Using a vernier caliper, measure the diameter of the elongated thread at the measuring point.
Measuring point
For intake side bolt 94 mm (3.70 in.)
For exhaust side bolt 89 mm (3.50 in.)
Standard diameter 10.85 to 11.00 mm (0.427 to 0.433 in.)
Minimum diameter 10.6 mm (0.417 in.)
If the diameter is less than the minimum, replace the cylinder head bolt.
