Cylinder Warpage

NOTE: If camshaft-to-holder oil clearances are not within specifications, the cylinder head cannot be resurfaced.

If camshaft-to-holder oil clearances are within specifications, check the cylinder head for warpage.
- If warpage is less than 0.05 mm (0.002 inch) cylinder head resurfacing is not required.
- If warpage is between 0.05 mm (0.002 inch) and 0.2 mm (0.008 inch), resurface the cylinder head.
- Maximum resurface limit is 0.2 mm (0.008 inch) based on a height of 100 mm (3.94 inch).





Measure along edges, and three ways across center.
