Jeff, I cannot understand why when a OEM Caterpillar part for a Caterpillar engine would be
any question in replacement back from an aftermarket non-OEM that has been installed on your engine. After while after being involved, providing technical support on engines that are aging
and areas of problems that recurring my mission has failed to explain myself any further at this
point. All of the membership on this forum are professional in our field, myself unfortunately Dave
Spent 42 years working with Caterpillar equipment. Dave has provided factual reasons of engine
problems and areas that leads to engine failure and high repair cost. Everyone has there own choice
how they maintain there equipment and Wish you best of luck ahead in 2019.
