Cylinder head bolts are tightened by plastic zone tightening method. Whenever the size difference between "d1" and "d2" exceeds the limit, replace them with a new one.






Limit ("d1" - "d2"): 0.15 mm (0.0059 in)

If reduction of outer diameter appears in a position other than "d2", use it as "d2" point.
