Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

The cylinder head assemblies may exhibit a brown discoloration before the rust preventative has been removed. The color of the rust preventative may vary from a light brown to a dark brown. After the rust preventative has been removed the base metal of the head assembly may show signs of discoloration.

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.

If there are any questions regarding the use of a particular cylinder head, please call for assistance to the Customer Interaction Center at 1-877-228-2420 or call the Reman Call Center at 1-888-887-6326.
