PROBLEM
C9 engines installed in certain 330D and 336D excavators may experience unacceptably high oil consumption. If certain conditions are met, the piston can experience carbon deposit build up that may lead to decreased piston ring effectiveness which may lead to increased oil consumption. The improved piston ring design is less sensitive to these operational conditions.
