Cause, if rusty #2 keeps failing to live up to the reliabilty bar of rusty #1 im going to be shopping for a daily driver.
Oh it happened way before 07. Some of the 4.0s in the last few years they were made had a knock issue. You could stick a drop light down cylinder 3 and see if in cylinders 2 and 4 because the walls were so thin.Make sure you get one of those adorable "It's a jeep thing" stickers and the upside down "if you can read this roll me over". Also it is mandatory to mount as many LED light pods on it as humanly possible. Then you will officially be a jeeper and can drive down the road giving weird waves to other jeep owners in a silent acknowledgement of your terrible decision.
Admittedly at least you're smart enough to know to stay pre-2007. Good lord it's like every Chrysler engineer came down with a sudden case of brain damage in 2007 and they haven't cured it yet. The old 4.0's were about as bullet proof as you can get though. Working on my buddies 2008 3.8 is pretty much a mandatory weekend event.
That should be equivalent to defacing a national monument. Our old 77 4.0 would probably still run if someone dug it out of the swamp it was burried in 20 years ago... I never new chrylser screwed with them besides adding fuel injection. I know it was originally an AMC engine back in the 60's and 70's and then chrysler stole it.
Bantam, Willys, Kaiser, AMC, Diamler Chrysler... what happened to them?
They were trying to save weight.
