This guy is kind of goofy but man I think he's onto something here. Nobody I'm aware of has noticed this before and it really makes sense.
To summarize the vid/discovery: With the cam change in the '09+ VVT Hemi the lifter upward travel is reduced to the point that the oil band in the lifter no longer overlaps the lifter oil galley. This is greatly reducing oil flow to the lower half of the lifter and thus the roller and needle bearings.
This perfectly explains why pre VVT engines don't suffer lifter failures, and why '09+ non-MDS fail at at least the same rate.
Dodge made a bunch of changes to the lifters over the years. But as far as I'm aware they never changed the oiling band. So it stands to reason that not even Dodge has figure this out.
