Cylinder Head Inspection for Warpage
  1. Check the cylinder head for warpage. Measure along the edges, and three ways across the center.
    • 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.
    • The maximum resurface limit is 0.2 mm (0.008 in.) based on a height of 115 mm (4.53 in.).
