So If you want to know EVERYTHING about the RAM 1500 EcoDiesel, you already subscribe to MoparEcodiesels Youtube channel, This guy knows his stuff, is very scientific and engineer minded in his approach to his truck and puts a crap ton of miles on his truck with a load so he has a fair amount of credability in my book and at 148,000 miles, his ED engine is torn apart because it failed.
(skip to about 3:00 in to get to the heart of the issue)
Turns out that the exhaust cam timing gear has a fatal flaw that allows the gear to slip on the shaft and best case your timing is off and your engine runs bad, worst case it eats your valves.
The sad news is that it sounds like its bound to happen to all these engines eventually.
Hopefully FCA/VM is looking into it.
