Oh sorry. No I can't see it being a jeep motor. No GM/Chrysler relationship that I know of.@Soaring no I know the Terri motor is fine and where it comes from, I almost bought one. I was reading somewhere (can't find it again) that the old Jeep motor is what is in the Colarado, not that I could see a problem with it, it just sounded unusual being and Isuzu vehicle?
I'm not sure what the relationship is now between GM and Isuzu after their split.
I know the GM plant in Thailand was out of action for a long time during the changeover. From what I understand, the split was not a friendly one so I'm not sure they would be sharing powertrains.
