First off, the M97 isn't a different engine- new name. Thats how we look at it, because we see the same issues and some that are M97 specific.
Details about my classes are found here:
Engine Rebuild School
I am adding many new classes in 2014, to include a performance M96/M97 class, Cayenne Engine Class, DFI engine class and several other hands on enthusiast level classes on top of the classes that are developed for technicians.
As far as sharing info goes, we share a lot, but we know a lot more.
