measure the warpage of the contact surface of the
cylinder block and manifolds.
Standard warpage
Maximum warpage
If the warpage is greater than the maximum, replace
the cylinder head assembly.
(b) Using a dye penetrant, check the intake ports,
exhaust ports and cylinder surface for cracks.
If cracked, replace the cylinder head assembly.
