Not tryin to be a dick either. Simply trying to know why this and that wont work and is not compatable. It's easy to say I'd have to change over a few systems. As far as asking more questions go I am digging for a reason.

You've said I would have to change over a few things. I'm thinking I can take some goodies off of the 98 4.0 and make it work. You say other systems but lack a description. Please be so kind and elaborate.

not too concerned with that little tid bit. certainly more worried about the nuts and bolts and getting it in there w/ all of the sensors and what not

Thought I'd start a new thread with hopes of more responses. Needing some details in how to go about throwing a 91 YJ 4.0 into a 98 TJ. I appreciate the help fellas.

Indeed I do have my work cut out for me. I understand there are some distict differences in the two engines. Have to make it work though. Needing some advice/suggestions please!!!

Snagged a motor from a YJ for $200. New rings, cam, crank, ported and polished heads. All seals were just replaced. Quality engine to say the least. As far as getting that 91 YJ 4.0 in my 98 TJ... I understand I may run into some ecu issues. Please elaborate on these as well as any other thoughts. T...

That's certainly an idea, dont know if it's really an option. Would really depend on how much the 4.0 was. Thinking 500 bucks would be in the ball park figure. That's total I'd like to spend on that engine. Best I can do, and yea wish me luck finding a stroked 4.0 with that...

Bad news...Definately the rings/valves. Costly to be 100% sure and pull it all apart. Thinking it will be cheaper to just replace it... I am going to post a new thread on engine swaps. Your advice is much appreciated. Thanks

Rings or the valves are bad in the jeep so I am thinking of replacing rather than rebuilding. It's only got 115k and is a damn shame. Any advice or tips? Engine sizes? Trying to possibly get a little more horses than the old 4.0 but am trying to keep my transmission. Simpler the better. Also know an...

Maybe figure it this weekend. throw a reply when its figured out. thanks guys

found one w/ 24k from a wrangler with the price right. thanks for the help

Sounds like the Durango box is the way to go. Wouldnt happen to recall the year on that Durango by chance??? Thanks Slinkey

My steering box has had a leak for quite sometime and have noticed a fair amount of play in this. I figure it's about time for replacing. I was wondering if say a Cherokee for instance or other Jeep models would work in my 98 Sahara. I appreciate the help!!!

very informative. many thanks. i do believe the whole moistue deal may be wishful thinking as I've put in quit a few quarts within the past week. hopefully after new years I'll run that compression test and go from there.

no blowout by the dipstick, no leaks/drips anywhere.
