Cylinder Head Distortion

Cylinder Head Distortion

Special Tool(s):





1. NOTE: Make sure all cylinder head surfaces are clear of any gasket material, RTV, oil and coolant. The cylinder head surface must be clean and dry before running a flatness check.

NOTE: Use a straight edge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 inch) per running foot length. For example, if the straight edge is 61 cm (24 inch) long, the machined edge must be flat within 0.010 mm (0.0004 inch) from end to end.

Using a straight edge and a feeler gauge, inspect the cylinder head for flatness in the sequence shown. If the cylinder head is distorted, install a new cylinder head.
