What happened if you dont mind me asking? When my 4.0 blew up, I replaced the clutch, throwout bearing, flywheel and seals. All OEM parts, figured I might as well do it while its out.

Lesson from my 4.0 replacement when cam went -> Go with OEM/Mopar sensors!

My first restart attempt when the new engine went it failed because of a non-OEM crankshaft sensor. Original back in got it to turn over no problem.

I would say start with new clutch flywheel TO bearing how many miles on your tranny that could be next issue you have AX-5 they don't last long in good form radiator is in what condition and water pump what condition something Id change immediately regardless peace of mind

Remanufactured engines aren’t that expensive.

I was thinking the same thing. Little u clamp on that sheet metal beam. Shake hands with danger.

Buddy and I pulled a 4 cyl out of a Willy with a seatbelt attached to a pipe that we put over our shoulders. I'm less than surprised the structure held....

I’m surprised you’re not considering putting a 4.0 in there.

It would be a nice upgrade from 4 angry squirrels!

Way back when I went to school we had English Class and Creative writing.

School...I’ve heard of those...

 

[Icecoldcooler]

Well thanks to little or no help on my first post to your forum did not know I was taking a writing class

It's not uncommon for people to go way off topic here. I've heard it takes almost as much to swap an inline 6 into it as any other engine. So if you do go bigger, I'd bypass the I6.

What's the verdict on the existing?
