If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.306 mm (0.406 in.), machine the intake valve guide bush bore of the cylinder head sub-assembly to a dimension of 10.335 to 10.356 mm (0.407 to 0.408 in.) to install an O/S 0.05 intake valve guide bush.

·

If the intake valve guide bush bore diameter of the cylinder head sub-assembly is more than 10.356 mm (0.408 in.), replace the cylinder head sub-assembly.
