Yes and ya I thought so too. Around here that's like very very cheap. I was a bit taken back when he was quoting me. He said there were a few he could throw in it. I just said as long as it isn't an 00 or 01. Ideally a late 90s if possible. He said they don't mess around as far as giving them bad engines, it'll be a runner for sure.

The jeep is worth keeping, I woulda bought it for $2000 for the body alone. You really don't see renixes in my part rust free. Its a dying breed for sure.

It has a 90 day warranty type deal on it, and the dude even said he'd for sure help out if anything came up down the line and wouldn't leave me hanging out to dry.

Sure a remanned or crate would be nice, but for $1400 with everything included, that's really hard to beat. That's less than a remanned engine by itself, and even if I did have the means to swap a 4.0 out of another xj (or could even find a good donor) I'd be spending a good $1000 on a donor truck or at least $750+ on a donor engine that I know nothing about and would be taking a big gamble on anyway.

Basically I'd be hard pressed to really do it much cheaper myself.

 

Just curious, even though you said you had other jeeps, whAt oil and filter were you running in this one.

 

9 times out of 10 it was Castrol 10w-30, but a few times here and there I threw some Mobil or Pennzoil 10w-30 in it, since it was leaking like a b1tch for a long time, so ya.

And as I said like 20 times - Wix only. The last 96 I had was beat to ****, was in like 12+ accidents, and had 320k on it when I finally had to ditch it - the body was too far gone. I got it for free though, and put like 30k on it.

 

If you're gonna get the replacement engine, see if you can be apart of ripping the old one apart. Might be a fun adventure

 

Out of sync? Now that's a new one

 

If it wasn't at a shop and I wasn't so busy with work and away all the time I would love to be there for it.

I'll be selling it after the swap.

I'll be getting my wife a newer car this weekend (Camry/accord/civic, under $8k with under 90k, 4cyl) either way, but it'll be hard to get rid of the XJ. I mean at that point it's a swapped engine, and just about everything else has been done already....

I'll be puting it up on CL for $4500 and see what happens, but I wouldn't want any less than $4k. At 4k I'd be taking a 2-2.5k loss, which isn't crazy bad, so whatever, it served us through 2 harsh winters.

Anyone that knows these vehicles and saw the parts list and complete lack of rust would know 4k is a good deal. We shall see.

The new, unforeseen work truck I now have (a brand new f150 4x4, paid for by the company) makes the XJ a lot less realistic than when I got it. I now have another 4x4 in case of emergencies, etc. Besides, my GMC is my baby, and I really don't need an XJ money pit laying around anymore, as much as my wife and I both love it.

 

I hope this guy knows what all he has to do to put a later-model engine into a Renix.

There was a poster on here earlier that said he was doing a complete 4.0 rebuild for less than $1000. I don't see how he can do that, unless he is doing everything himself except for the boring and turning the crank.

 

Good to know you've never broken a tooth off a gear ever.

edit- or have seen worn teeth, or of round centering pin, or gouged center pin, or cracked body

 

I was the one mentioning putting in later models - he might just be finding a renix era one, I'm not sure.

I hope it doesn't wind up racking up the price as he winds up "running into things" - we'll see I guess.

At this point I just want it done so I can sell it and forget about it. I put too much damn work into this thing. It's crazy how much work I put into it in such a small time, for it to just go and die so young anyway.

 

I was told by an engine rebuilder that when it comes time to rebuild my '87 Renix, he will have to use my block and head because there aren't any good rebuildable cores available anymore.

I think Cash For Clunkers got a lot of 'em.

According to others on this Forum, a later engine into a Renix is basically treated as a long block swap. All the Renix peripherals go onto the later block.

Even though your guy says he knows where several 4.0s are with less than 100K miles, in my area they would be as rare as hen's teeth with that few miles, given the age of all of them now.

 

No, yes, yes, yes, and yes.

Now, from this pic: http://repairguide.autozone.com/znet...3f802053d1.jpg
please explain how they can come "out of sync" , other than worn or broken???

Speaking only about oil pumps.

 

Yes, I'm doing everything myself. The shop will hone/polish/grind what I need. The rest is up to me. He will measure everything as well. Oh, the wrist pins and the cam bearings will be installed by the shop as well.

 

So here's the video


At least it started up twice right away, it actually doesn't even sound crazy bad, but definitely seems to be fubar.

The optimistic side of me still thinks a new oil pump might clear this up if there is in fact no internal damage, but if it doesn't, and there's already internal damage - that's a lot of wasted time and money.

Got my wife an 03 civic ex coupe yesterday with only 77k and a few tasteful mods already done (intake, exhaust, tint, and a serious system). Pretty nice whip.

I'm thinking I'm keeping this XJ though after a swap. I guess I wouldn't be surprised if this is saveable, but if damage as been done which I'm sure it has, it's just not worth it.

Thoughts?

 

That does not sound good at all.
Sounds worse lower end,maybe rod or crank bearing?
Anyone else?

 

Ya it's fubar...

Will be getting a swap, I'll be talking to the shop tomorrow more in detail. I'll see what kind of engine they can get, and get a decently solid $$ number out of them. I'll have them re-use the bosch type III injectors (just did them), I have a brand new alternator laying around for it, and I'll have them do engine mounts, RMS, pan gasket, oil pump, and see what else they might have in mind.

Who knows what did it, could have been the oil pump, but it could have been a lot of other things as well. It was a tired engine, it had low compression and a ton of blowby. Who knows what the PO was doing with it, the steering system was fubar as well and I had to completely re-do that too. He just neglected the crap out of it. Well it was actually his daughters, which might explain it.

If I can get another engine in there for a decent price, it's not too bad of a hit. I'm not THAT deep into it money wise, and at least by then literally everything on it will have been changed (except for tires, which are still good but I need new ones, which by then I'll be doing a budget 2-3" lift and throwing 33's on it)
