Here is what I have determined on my limited research. The ISX (EPA 2007) is the engine that may have the valve issues. It is the pre-DEF engine with a dual overhead cam design. The ISX15 (EPA 2010) was the next model that is a DEF engine. It has a single overhead cam design.
The above coach #1450 has the ISX I believe. Newell probably had some remaining in stock, and the owner elected to go with the pre-DEF engine. It may be in my best interest to look at later 2012's or 2013's.
