I certainly am familiar with your situation finding mechanics that are not only experienced, but willing to work on antique Detroits. Leo at All Abord America in Mesa was very good to us, including an emergency air brake repair, but was very honest about the pitfalls of chasing parts that are getting very difficult to find. When it was time for a major survey of   our 8V92TA coach, we made the journey to Bus Grease Monkey Garage in Centerville Tennessee. He does nothing but 2 cycle Detroit powered coaches. We had a 50 amp hookup at his place, and every day they worked on our bus, and only our bus, until all jobs were checked off our list. Good luck with your Newell.
