Cylinder Head Inspection For Warpage

Cylinder Head 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 121 mm (4.76 inch).
