that any corrosion problem with the engine be reported so that improvements can be made to
prevent the problem in the future. While corrosion is typically associated with rusting of metals, it
softening, swelling, or breaking of these materials may be a corrosion problem. If a corrosion
problem is identified, it can be reported using SF 368 (Product Quality Deficiency Report). Use
information is identified as a CPC problem. SF 368 should be submitted to the address specified
