Finally Found A Remanufactured Engine!

I bought a 4.0 from titan 2 years ago, the engine has held up fine. I drove down and got it to save shipping. I've used a strait 30 weight diesel oil since I got it.
One pointer I'll give you is take out there rear main seal and put in a mopar. One year after I installed my engine it started leaking and I replaced it with a mopar. They had used felpro gaskets and seals.
There's some things you have to take off your core before you trade and if your motors locked up they don't give you core money. Good luck on project !!!!
I wonder if you replace it before it’s installed. ( the rear main seal) if they would back out of a warranty from it? But still good advice. Most of the issues I see online is with their stroker engine, I think it’s the 4.7. Which a lot of people put in their Jeep’s. I don’t even know why they call it a stroker? I would go right back to the 2.5. I’m glad yours turned out good. Still trying to decide what to do.
 
It’s not every day I see a 2.5L swap for another 2.5L which is what I would do so I’m very interested in your experience and outcome.

A 2.5 to 2.5 swap is probably the cheapest/simplest way to go. Any other engine requires a different transmission, and the main shaft of the transfer case needs to be changed. Motor mounts are different, different wiring harness issues, etc. Even doing a 2.5 to 4.0 swap same year isn't a direct engine swap. Unless you've got a donor 4.0 Jeep. It'll be the little things that cause issues.

Of course Jeeps are one of the most common vehicles for engine swaps. I would have loved a small block V-8 instead of the 2.5, but I wasn't wanting to go there. Plus I had a new 23 JLU on order, so I was wanting to keep it not so expensive. It still came out more expensive than I wanted (figure $6000 once all said-and-done), but the TJ was 25 years old as was a lot of the parts still on there, so I figured I'd do it right while I had the chance. Pay once, cry once I guess. Between the TJ (an unexpected expense) and the new JLU (which I had ordered but not received yet when the engine blew) I think I'm still crying a little bit.

I always found my 2.5 to be adequate. I haven't had to deal with Titan other than with the initial purchase, so I have no comments on their responsiveness.

If you've got over 200,000 miles on your engine, there are probably a lot of things you should replace for good measure while you've got the engine out. I think I listed what I replaced earlier, but things like motor mounts, radiator, water pump, exhaust manifold, hoses, clutch fan, belts, plugs/wires/cap/rotor, etc. Anything that wears or wears out (like motor mounts) I'd recommend replacing while it is right in front of you. So that'll add to the $1100 your mechanic quoted. My shop also ran the injectors through their cleaning machine. So that's why mine was like around $6,000 when all said and done.

The year prior my clutch went, so I had all new clutch stuff and the heavier flywheel installed. But if yours has 200,000-plus miles on it, now's the time to replace all that stuff.

Yea I just replaced my clutch 1.5 years ago as well. I wish I had the money to replace everything. I may have to go cheap on this though.

Check this thread out regarding a heavier flywheel:

I wouldn't have done it unless the clutch needed to be replaced anyways, And it did, so I did. Here's me on the IDBDR (summer before engine blew). The TJ is my overlanding Jeep.

The guy from Titan I spoke with said there is a 3 or 5 year warranty, unlimited miles. I’m concerned though because the complaints on their stroker engine. A lot of people said they made it impossible to claim. Like take the engine back out and ship it to them. But that may not be true. And who knows maybe just the stroker engine was being put into situations it should not have been. I don’t know. Is good to hear a equal to equal swap worked for you. I may call Titan again tomorrow and ask about their confidence on the build and off the break in period is obtainable being a DD. Also the zink and oil questions.

That's the oil they're going to tell you to use in south.
The stroker motor is a whole different ball game than the stock motor, it's a high performance motor.
When you get a motor from them you just get long block, you have to put oil pump and pickup on and a ton of stuff from your old motor. They give you a box of gaskets (felpro). They don't know what you or your installer has used in way of gaskets and seals.
I'm not trying to sell engines for them but there known for quality jeep engines and mine was great except main seal .
And I've used that oil for over 2 years and 12,000 miles.

Thanks so Much. The picture helps. I’m going to look around here to see availability. So I take it you still have your Jeep with this engine? This was all good information.
 
So today I drove the TJ to the Cabela's in Olympia. Why?

1. I like Cabela's. I have a Cabela's credit card that I get points for purchases using their card. So when I go to Cabela's, I check in at the front desk and see how many points (dollars) I have credited to me. It's like shopping for free! I put the Titan engine stuff on my Cabela's credit card (figure $6,000.00 total), so the points added up.

2. (And - more importantly) it is over 160 miles round-trip for me there-and-back from where I live in SW WA, so I knew it would put me over the 500-mile mark on the Titan engine. Seems like it was taking forever to get to the 500-mile mark on the TJ.

So now I have an appointment 1 August at the place that did the engine install for a 500-mile oil change and to give it a "once-over". The engine is running great, no funny sounds or anything. AC works fine too. I'm happy with it so far. I did have a check engine light come on once that said it didn't recognize the catalytic converter, but I cleared it and it hasn't returned. I think that was just a hiccup when starting it once. I haven't been checking my MPG during all this, so nothing to report there.

Is it typical that a engine comes sealed in a bag that has oil at the bottom of the bag? The engine was picked up but there is oil collected at the bottom of the bag. I thought these do not come with oil in them. Is there a reason for this?
 
The engines are well oiled before they're sealed in a bag. Keeps them from rusting. Keeps it slippery. This is a good thing. It is ok if some oil drains down.
 
This is currently true. I made some phone calls this week.

ATK has a performance division that you can order directly from. Like Stroker engines.

But if you want a regular reman engine then you gotta go through a whole seller like autozone.

Autozone has my ATK engine with new oil pan and timing chain cover for 2,399.00. Free shipping

410$ refundable core charge
4yr warranty

But delivery date is April 1st. I want to call ATK on Monday to get more info.

I bought an ATK 4.0 from Autozone in March of 2023. Today, less than 10K miles and it is trashed. Rockers are making a hell of a racket at cylinder #5. Metal shavings on the #5 cylinder head, #5 cylinder head rod has scoring, mis fires in multiple cylinders, and loss of compression in 3 cylinders. ATK are working with me and the local shop to diagnose the problem. Sadly, they want us to remove the head before any repair plan is developed. What sucks is that anyone who knows motors, knows that a 4.0 with metal on top of the head with multiple cylinders involved, that the motor is hosed. A rebuild in the shop is going to cost more than a replacement motor. All oil changes were done - 500 mile, 1000 mile, 3000 mile, and 6000 mile. Each involved conventional and zinc additive. We will see what the lifters and can show later this week.

It seems to be the nature of the beast when having issues after purchasing from a non-local builder. This is similar to the nonsense I had to combat with the Reman company when I had transmission issues. Sorry man :(

I understand that they want to ensure there isn't proof of negligence on your part before they proceed and they want to see if it's just a top-end problem. But, it's frustrating to deal with when your big purchase is trashed.

I'd like to think that purchasing through Autozone could be helpful since ATK would be wise to keep them happy. Keep us posted on how things go.

Got word today that ATK will replace the motor. Yesterday the mechanic and I could visibly see that the lobes on the cam for cyl #5 were damage and one of the lifters was dished and even worn through. Motor oil has visible flecks of metal. Cyl #5 has much greater coke deposits than the rest. Sadly ATK asked the mechanic to spend 18 hours worth of time to get the information they needed. An engine swap takes 10 hours. I get it, it is not their money, what do they care? Now they can reman this motor again. Hopefully it does not take them a month to get a motor to the shop.

Im sorry you're going through this, as Ive been somewhat there with a transmission. Hard lesson to learn. That said, you couldn't locate a local machine shop near you to do the work and rebuild your OE? After reading about people's issues with their reman supplier's, I plan to have mine locallt rebuilt, if and when it dies.

Great to hear that they are replacing it.

Sorry about the labor costs...maybe they will help some. My transmission's warranty only covered parts by the time had issues with the solenoid pack & valve body.

So my reman ATK engine is also shitting the bed just 1500miles later. Currently in the warranty process. But they want my mechanic to take the head off look at lfters and cam

IMO it’s the fucking piston. There’s a guy on YouTube called dexjeeps and it’s almost always a cracked piston skirt. Regardless all of this is just so damn fucking frustrating.

Sorry man. I feel your pain. Once they get the head off, the mechanic should be able to tell them what failed and then they should replace it.

Last year I talked to a couple repair shops near me. Non of them have the techs in their bullpen that can handle an engine rebuild. There are not too many good machine shops near me that can do the machining required. I remember as a kid in the 70/80’s the machine shops were all over Southern California. Not so many left here in New Mexico. Plus, here in New Mexico it is very hard to find shops that stand behind their work. Not kidding, most shops are so dishonest that you just walk in knowing something is going to be FUBAR and it will be the customer’s fault. This and time is why I opted for a reman from a large chain (AutoZone).

I decided two years ago that I'd go with S&J if I don't have it rebuilt locally. That said, there's no gurantee that either route will not be a nightmare. I'm holding off as long as possible.
