I've found a 95 N/A that I'm interested in, but have some reservations about this motor given the talk about the (#6?) inlet valve recession issue. I'm looking for one of those 400-600k experiences that we so often hear about on forums like these, and am prepared to commit the necessary care and maintenance to realize any such potential. As far as I can tell this is mostly limited to the OM617 and OM602 motors, but I'm hoping some knowledgeable soul can convince me otherwise with the OM606.
