any corrosion problems with the engine assembly be reported so that the problem can be corrected and
improvements can be made to prevent the problem in future engine assemblies.

materials, such as rubber or plastic. Unusual cracking, softening, swelling, or breaking of these materials may
be a corrosion problem.
