Refer to Table 1 in order to see the cylinder heads that are affected.
Some cylinder heads may be shipped with the blue rust preventative. This rust preventative may change in color from blue to brown.
Solution
Either the blue or the brown color of the rust preventative may discolor the base metal. However, when the rust preventative is removed there will be no noticeable pitting of the base metal. Therefore, the discoloration of the base metal does not affect the functionality of the cylinder head assembly.
