I had a '95 ZJ for 19 years and over 300,000 miles, and never had the head off the 4.0L ! But..the cracked exhaust manifold was replaced once with an OEM, which also cracked, Then with a "bellows" type expanding manifold, which robbed power. I then tried a Banks Engineering unit, which worked great and produced good power increase...until it cracked. Finally I tried a Borla, which sounded great, and I could feel the power increase! All was well again...until the old ZJ was hit from behind by a Peterbuilt and turned into an accordion. But the Borla was a great choice and lasted longer than any others. I sure wish I'd had a video like yours to watch b4 I did this the first time! Nice job, and entertaining too!
when i did my manifold i didnt have the alingment dowels for the intake seated properly so when the bolts were tight there was a gap between the intake and head. First time i fired it it reved to probably 8000 rpm lol.
Just delete your comment if it’s not going to be helpful. Not trying to be mean but people looking are trying to do this job so if you have tips and tricks make your own video or tell us
Thank you for this How To. I found it helped (very much) to have a helper (my girlfriend) for grabbing dropped bolts & holding the intake manifold while we maneuvered the header & gasket in & out. We left the intake manifold mostly together, only removing the air intake duct.
throttle body can stay on and you only have to tag 4 injector plugs because no 1 and no 6 can not get mixed up and tps and every other plug is different and can not be mixed at all so no need for them to tagged at all , and underneath the last 3 inlet manifold bottom bolts can be wound in 1 thread when putting it all back together before putting inlet manifold in place and you can put inlet manifold in place over the 2 mounting /positioning studs and put a top bolt in place on any top position and then you can get the bottom done up easy without having to line up the 3 impossible to see holes in head to thread bolt in
Anyone else worried about engine fire from the damaged flexy line to the fuel rail? Hope it was just my eyes but may need to get that changed if you didn't already 👍
It is a good idea to put a rag or a shop towel into the throttle body throat or the manifold opening when you have the air cleaner off. Bolts, nuts, pistachios have a way of falling in and if you don't see them, they will get ingested into the engine.
1:41 NEED to loosen the nut that holds the power steering pulley and locks it in place, it’s on the front. It needs to be loose before you can loosen the belt.!.
Hey Patrick! Great to meet you today ( Cell Phone Repair, Nashville). Give Chris a call, he will take care of you. Funny, I just did this exact job on my XJ 3 weeks ago!
Dang, a pain in the.... just to get to the exhaust manifold. Having a "cute helper" makes the job not so bad eh. Thanks for the coverage and info..sounds and looks good👌
A few hour job! a very common repair on the in line 6.... The header's all or most of them Break, crack... I welded mine.. I've Replaced 4 header's on customer's cars, mostly on the Grand Cherokee Vehicles!
Before getting into this I hope you did this the right way by installing the intake first then the exhaust so you don’t have the clearance issues getting to those couple bolts on the intake if you do the exhaust first as most will do..
Will this cause a big drop in mpg? I bought a 4.0 97 TJ and I know mpg isn't great to begin with but I only get around 200 miles a tank. I was told it has a bad exhaust manifold gasket when I bought it
I was wondering the same thing.... I just found a leak in mine where it forms into one and im wondering if I can wake a couple weeks to get some money..... but this looks like he ran it for a couple years lol
Ya'll know and I think everyone will agree we like the broken manifold exhaust note better but yeah (THEY) make us do things like put mufflers on our stuff.
So this may seem like a stupid question coming from someone who's not very mechanically inclined.....but was that a header? Or was it just a regular plain old exhaust manifold? By the way, I enjoyed watching your video.
There should be like 7 bolts and 2 studs on the end. I just bought an exhaust hardware kit, and that's what I got. The two studs hold the exhaust on, and the bolts hold both the intake and the exhaust on. That was very common on inlines in the 60's. Some had these little 3/4 washer clips things that also held it all together.
And to think I could buy a ~98 Cherokee from my coworker for $600, this being the main thing that needs to be fixed hopefully 👀 U[date: I ended up buying it and my thoughts when you started it up afterwards were “that’s so quiet”
All these "manly" jeep fanboys complaining about a bit of silliness, don't worry guys, keep doing what you do, I found the video fun, plus she's cute:)

trjnsd dude glad you’re okay🤘🥞 and great information🥞🥞 thanks for commenting and stay STICKY out there
Pro Tip: After removing a carb or throttle body, tape over the opening so screws and little things don't accidentally fall into the engine.
when i did my manifold i didnt have the alingment dowels for the intake seated properly so when the bolts were tight there was a gap between the intake and head. First time i fired it it reved to probably 8000 rpm lol.
My favorite part about changing the manifold gasket in my Comanche was pulling the head to drill the broken stud in the back.
oh man that sucks
I would invent some new curse words if that happened
I don't think u guys said sticky enough
Full Circle Diagnostics our thoughts exactly 👌🥞🥞🥞
As a professional automotive technician and Jeep owner I have some critiques for you. Unlike the rest here though, I'm gonna keep them to myself.
three wheela Then what the hell is the point of your comment?

Nice job guys. This seems to be a fairly common occurrence with the 4.0 engine.
It is
with the engine that long, 1 & 6 are a bit lean and get hot.
But I love when carb cleaner deflects off and sprays directly in my eye
I`ve heard that hurts. (like I haven`t done it a few times.) bwahaha
Anyone else worried about engine fire from the damaged flexy line to the fuel rail? Hope it was just my eyes but may need to get that changed if you didn't already 👍
Craig Prior good eye dude we will have to do an update once we get that done! Thanks for the pro tip🤘🥞🥞🥞

No it's not your removing the entire manifold in this job
Is Tyler still around? Are there any videos of that 7 bay shop he was building?
1:41 NEED to loosen the nut that holds the power steering pulley and locks it in place, it’s on the front. It needs to be loose before you can loosen the belt.!.
Would have been a good time to do block side motor mounts
Thanks again , because i have to install a knew header to my Jeep tomorrow.
What about the upstream O2 sensors?
Wouldnt deleting them cause loss in performance?

thank you for the great how to video as this is my delema as well!
My favorite was watching that poor little gasket get launched by the fan at 12:17 🤣
My zjs tensioner was in the same spot as yours and I broke all my bolts on my manifold they were that stuck and rusted
I'm getting ready to do a head gasket. I ordered new manifold bolts to save myself the trouble.
Well done job and step by step remove and installation.
Only he didn't show how he was able to connect the headers to the down pipe.
Thank you Uncle Sticky and lil Sticky Nice job
Good job guys , made that look sticky easy!!
OMG is that Deep Amethyst Pearl? I felt like I was the only one with one. One of the best colors made!
Brother. Ohy.vey ;
what is the filter on top of the engine that looks like a cool air intake?
Nice job. Try this on a '94 Cherokee like I did. Very tight.
Whats with the cone filter on the pcv valve? Is it an upgrade, or an adjustment bc of the lack of an airbox?
A few hour job! a very common repair on the in line 6.... The header's all or most of them Break, crack... I welded mine.. I've Replaced 4 header's on customer's cars, mostly on the Grand Cherokee Vehicles!
Hey folks...When welding the header....clamp it to a true straight edge. Keeps it from warping from heating/cooling.
Before getting into this I hope you did this the right way by installing the intake first then the exhaust so you don’t have the clearance issues getting to those couple bolts on the intake if you do the exhaust first as most will do..
The intake is supposed to go on first? So you put the intake on and then the 2 nuts on the end to keep the exhaust in place?
No mentions of how easy manifold bolts break off in the block.
Can't wait for lamazeen to be done
Will Dunn dude neither can we 🤘🤘🤘🥞🥞🥞
@@patpollifrone9827 dude that truck beds gonna be so sick stay sticky dude
How is that intake set up treatin you guys ?
that exhaust seal looks fine, snowmobile exhaust seals look the same
Great stuff workin on a jeep that is actual a jeep
Boo gtfo with your real jeep nonsense, this is bleepinjeep
I'd put my XJ against your "actual jeep" any day
Will this cause a big drop in mpg? I bought a 4.0 97 TJ and I know mpg isn't great to begin with but I only get around 200 miles a tank. I was told it has a bad exhaust manifold gasket when I bought it
Definitely, if it’s this bad and throws off your readings to your oxygen sensor.
Got have a vacuum cleaner process going on with the sticky debris
Man how long had that thing been leaking exhaust before this epipes finally let go? 🤔😂
Edit: that fuel line pen piece was a nice idea.
I was wondering the same thing.... I just found a leak in mine where it forms into one and im wondering if I can wake a couple weeks to get some money..... but this looks like he ran it for a couple years lol
Do you know what brand the manifold was that you removed? Don’t want to put that on my Jeep
jeepmansopinion I think it was a cheap summit brand. Not 100% but when I was looking there were a few cheaper ones. I would stay away from those.
It’s a lead packed gasket for your exhaust. Everyone I’ve ever seen looks the same.
Safety 3rd - Mike Rowe
She said “ you are all that is man, baby” ... my heart melted and I laughed out loud
Used a mirror to see the bolt, is more easy. I do it believe me.
Do you think it broke because it had no flex-joint or flex-point at all?
Heat cycles.
Exhaust crash.
No flex in exhaust/ too much flex.
Mismatched engine and trans mount materials.
Etc
Ya'll know and I think everyone will agree we like the broken manifold exhaust note better but yeah (THEY) make us do things like put mufflers on our stuff.
Not sure if you need to label everything other then injectors everything should only go back one way.🤷🏻♂️
So this may seem like a stupid question coming from someone who's not very mechanically inclined.....but was that a header? Or was it just a regular plain old exhaust manifold?
By the way, I enjoyed watching your video.
I didn't realize only two bolts hold on the exhaust - I thought it had at least 12 (2 for each valve port)!
There should be like 7 bolts and 2 studs on the end. I just bought an exhaust hardware kit, and that's what I got. The two studs hold the exhaust on, and the bolts hold both the intake and the exhaust on. That was very common on inlines in the 60's.

Your face reminded me of the ice age movie with the little kid and the Indians
I have that exuast manafold. It still cracked 😪
If you put a wj mainfold on you get better flow
Are you talking about the ( INTAKE MANIFOLD ) ?
@@NoWr2Run I think so. I was thinking I would have sourced a newer intake if I was that far in.
needs some Magnaflow headers
You are all that is man baby That's something I want to hear every day from my wife
No wonder it turned out great...you had professional cat help! 😜
American Racing long tube Headers Jeep Tj ill do a review they are a amazing
This job is a massive pain in the arse.

Matt! I love these guys!
That’s a nice hot air intake. Baboons.
TURN YOU MUSIC DOWN. WOW.
