There was a huge thing about a ton of bad China made valve stems. My 2006 RTV900 had them on it and the rubber just rots out. I broke the beads down and installed good US made stems and moved on. A whole bunch of cars hade the bad stems too...
The 11-14 6.7L have a turbo problem. There are many upgrades including one ford is working on. The 2015 trucks will have a different turbo.
