VIM 3.0..... saw the engine in a 1500 3 years ago as some guys from the proving grounds stopped by on their testing.... still had the Jeep top cover when they were flogging it. I'm HOPING with the newer emission systems (DEF) that they will see less issues than the Liberty did. Not a lot of them out there, but so far I've replaced a NAC on a truck and a Jeep Grand Cherokee, but there's also a TSB out for that now.
