CYLINDER HEAD BOLT RE-USABILITY





The length below the head of the bolts should be within (A): 99.4 mm (3.91 inch). If it is outside (A): 99.4 mm (3.91 inch), replace the bolts.

Using a straight edge and feeler gauge, check the cylinder head bottom surface for flatness. Flatness should be within 0.05 mm (0.002 inch), and wear limit is 0.2 mm (0.008 inch). If it warps excessively, correct by grinding up to 0.2 mm (0.008 inch) combined with block deck grinding. The height of a new cylinder head is 132 mm (5.197 inches).
