When you really look at it though, this problem of the lifter and cam failure didn't develop until 2009-2016,2017ish. 2009 is when Chrysler completely redesigned the Hemi, and they put VVT in it. I think it has a lot to do with the VVT. It puts more lift on the valves to my understanding,so in my mind. There is more pressure on the roller???? Throw that into what uncle Tony is saying. Makes sense why this is happening.
