3.6 Pentastar Rattling

@Trojmn, you make a compelling point -- its just a car and it can be fixed! But somehow I'm not as motivated to dig into a 2014 minivan as I am to dig into my 72 Swinger. ( Not that the 72 ever needs it -- its ridiculously reliable.) I just have to figure out what exactly is wrong with the van. Changing a alt or a tensioner is one thing -- opening the engine is a whole other thing.

I took this video in which you can hear the sound. It doesn't "feel" like it's the valve train -- power smooth, idle is smooth -- its not super rhythmic -- it's more of a rattle. NO check engine light and NO codes.
