It is not an "off year" and should not be avoided.
What exactly are you wanting to do?

Got stuck in a snow bank last night and had to have a buddy pull me out. First tried from behind but I didn't have any towpoints so I had to manage to hook it to my frame. I put one hook in a hole on the right which held up fine. But I hooked the other to this part of the frame that dips and become a like half-pipe until it gets thick again. It "ripped" that part of the frame and took some metAl out. but only part of it because it was more rusted than I thought. Is that fixable? It's on a 96 xj 4.0 I6.

Pics would help, but it doesn't sound positive. There is no "frame" btw.

Need pics for sure.

Leaking from my steering box.

I went wheeling last week in my 99 Cherokee. I have a 4.5" lift with 4:10 gears and lunchbox lockers. First trip with the lockers and it was awesome.

Crawled under today to make sure everything is tight and noticed the bottom of my steering box has oil on it. Is there an easy to replace seal or am I looking for a box from the ZJ.?

If replacing, am I looking for any particular years?

RSWiser

Wanna swap motors. I haven't bought one yet. Guy at scrapyard told me his "electronic computation device" says it's a on off year w electrical. Things on it were different. Sooo... Getting some advice on that before I shell out the duckits for a new motor.

So as long as a pick up a 4.0 HO, I am good, regardless of year?

Thank u salad & cruiser!

Tell your JY buddy to look at both of these. LOL.


Cruiser’s HO into Renix Swap

This swap is easier than some will lead you to believe, generally those who have never done it. Those of us who have done it, like myself, will share with you the things that need to be done for a successful swap. Just think of it as swapping in a long block.

The HO and Renix have some differences but none that can’t be overcome very easily.

Any HO engine from an XJ or ZJ through 1999 can be used. One running change was that the rear of the head was no longer drilled and tapped for the temperature gauge sender beginning in the 96 model year. The sender can be relocated to the threaded hole in the thermostat housing taken from the HO engine. You’ll have to extend the wire to that location. Some brave souls even drill and tap the HO head for the sender.

You will be using the intake and exhaust manifolds from your Renix, along with all your sensors and wiring. Since the intake ports of the HO are slightly different, you use the Renix gasket. Exhaust ports are identical.
You will need to use your Renix distributor as it is different than the HO because they use different fuel management systems. The flywheel or flexplate from the Renix must be used so your CPS gets the correct signals. The valve cover from the Renix allows you to keep your CCV system intact and requires no modifications.

The HO block will have a plug in the coolant galley on the driver’s side of the block, closest to the front, which needs to be removed so your Coolant Temp Sensor can be installed in it’s place just as it is on the Renix. It requires a 5/16” square drive or a modified 3/8” drive that has been ground down to fit. Do this before installing the engine.

As for the knock sensor, which is located just above the oil pan on the driver’s side of the engine about mid way, all the blocks I’ve seen are threaded for it. If not, I’ve heard they may be drilled but not tapped. Tap the hole if that’s the case.


Revised 03/28/13


XJ Cherokee and ZJ Grand Cherokee 4.0L engine blocks interchange.

2000+ TJ Wrangler and WJ Grand Cherokee 4.0L engine blocks interchange.

XJ/ZJ blocks and 2000+ TJ/WJ blocks do not interchange without significant modifications. (1991 to 1995 YJ and 1997-1999 4.0L TJ Wrangler blocks will interchange in XJ/ZJ and visa-versa).

TJ/WJ 4.0L Engine blocks underwent clean sheet design changes effective in the 1999 WJ Grand and 2000 TJ Wrangler. These blocks are not interchangeable with XJ/ZJ engine blocks. The reason is motor mount bolt holes and belt driven accessory mounting bolt holes are in different locations, or not present at all, TJ/WJ vs. XJ/ZJ.


XJ: "Regular" (not Grand) Cherokees 84-01
ZJ: Grand Cherokee 93-98 (Gen1)
WJ: Grand Cherokee 99-04 (Gen2)
YJ: Wrangler 87-95 (Gen1)
TJ: Wrangler 97-06 (Gen2)

So all of these compatible with 4.0, right? I say all of that to say this? Again, I am going from a 4.0 ho (non renix) , looking to go to same, just different year.

Well, the first doesn't apply then...

That's okay. 91 to 99 would be fine.

So I have a 1999 jeep cherokee and it's saying I have low oil pressure when I just changed my oil today with 10w30 full synthetic, but when I give it some gas it goes back up, any ideas?

How low? How up? What filter? Have you tested it with a mechanical gauge?

Is this something new?

What brand of oil filter?

Did you whack the oil sender getting the filter off?

It was very bottom where the light kicked on, and I had the ph16 firm guard filter, and I haven't used a mechanical gauge, but the jeep doesn't lose oil and runs just fine and it just recently started doing this

Describe "recently". Before the oil change using the POS Fram oil filter?

It did it before and recently like a couple of hours ago and it still does it
