I have now counted 7 people I know that all have new Ram trucks, 2013 and newer, all of them with the 5.7 hemi, and not a single one with any funky smell of anykind. This is the most bizarre issue I've ever heard of and am thinking that this could all be an act of a single (or even a couple of people) disgruntled saboteur? I've been around engines and various compounds all my life (all my patriarchs are motorheads, engineers and technicians) and have never encountered anything remotely like what's being described in this thread. It's just very unnatural. My sympathies to those that are dealing with this but it sure is strange there is yet no real description of how this happens.
