Cylinder Head Inspection For Warpage

Inspection for 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. Measure along the edges, and three ways across the center.
- 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 105 mm (4.13 inch).
Cylinder Head Height:
Standard (New): 104.95 - 105.05 mm (4.132 - 4.136 inch)
