Cylinder Head Inspection for Warpage

  1. Check the cylinder head for warpage. Measure along the edges, and three ways across the center.
    Warpage
    Standard (New):
    0.07 mm (0.0028 in.)
    Service Limit:
    0.08 mm (0.0031 in.)

    • If warpage is less than 0.08 mm (0.003 in.) cylinder head resurfacing is not required.
    • If warpage is between 0.08 mm (0.003 in.) and 0.2 mm (0.008 in.), resurface the cylinder head.
    • Maximum resurface limit is 0.2 mm (0.008 in.) based on a height of 120 mm (4.72 in.).
    Cylinder Head Height
    Standard (New):
    119.9−120.1 mm (4.720−4.728 in.)
