For anyone doing this job in the future, I recommend loosening the egr pipe from the intake side of the engine. You will easily be able to slide the exhaust manifold off the head without having to crank on the egr pipe. Great video Tim.
Love the channel. Friendly tip there is a 12 mm bolt that connects the EGR pipe to the engine block, that runs between the firewall and the engine block. If you follow the pipe down with your hands you will feel a bracket. That should give you a little more wiggle room if you loosen that bolt. If you need even more room, then after you loosen that 12 mm bolt, You can loosen the bolts on the other side of the EGR pipe.
Just completed this project using your part #s and only ended up with two extra parts since I went without the heat shield I had two bolts for it. Also had a copper flat washer ? Other than that this upgrade worked for my 3rz in a 1995 toyota t100. Feels a little peppy now and quieter thx once again guys.
You're welcome Tim. Glad our video helped you get the job done. I can't remember a copper flat washer as part of this job, but my memory sucks, so who knows if it was needed or not. The only copper flat washer that I can remember using on these rigs is for the front differential drain bolt.

You guys are so lucky where you live where there's no rust. Doing that same job here in Chicago/Shitcago means busting out the oxy acetylene torch and cutting off every single nut and bolt. Welding on a new exhaust pipe flange because there is nothing left of the old one to bolt the new manifold too.
We know. Every time I see somebody post pics of their 4runner and they're from the rust belts of the country, I cringe when I think of what they have to go through to work on that rusty mess.
@@TimmyTheToolman The old studs are fine, I just meant putting the studs in before before hand. But still love your vids, very detailed and thorough. Hope to do that front locking hub conversion on my sequoia soon.
Hey Tim, How are you brother? I noticed that you don't have too many videos on the 3rd gen 4runner exhaust system. So, I'll ask this question since your videos are the ones that get me through these repairs. I have a 99 4runner 3.4 w/federal emissions. Years ago, I replaced the cat back on my own no problem, but now I need to replace the cat and o2 sensor since the studs on o2 are rusting to nothing. I have no codes yet, but figured I swap out these parts while it's still warm in the midwest. I noticed that there is one broken stud out of the three in exhaust flange where manifold connects to catalytic. I have the type where there are two gaskets in flange. Im probably getting a leak there from the broken stud with no nut. The other two nuts are there and then there is the bracket bolt that is rusty too, is this 14mm like the stud nuts? My questions... How does one access the stud/nut under frame section? It seems there is no room to get a wrench or socket in there. Which direction do the studs turn from underneath the vehicle? Do the studs and nuts turn in the same direction righty tight lefty loose? I want to make sure that I'm turning in the correct direction to remove. Im going to try and heat these up to get off once I receive my E8 and E10 socket, hopefully this helps. Any tips and tricks are greatly appreciated. Im super sore from being under there yesterday with no luck. Thank you very much Tim! You're the best!
Yes, those nuts are 14mm. The exhaust studs turn into the exhaust flange clockwise to tighten and counter clockwise to loosen. The one near the passenger frame is harder to deal with if it breaks because you can't get a straight shot at drilling it out so you can retap it. Those studs can be really hard to get out. Even with heat and penetrant, you will most likely break some of them. You might want to remove the exhaust manifold if you have to drill any of them out. Maybe you have a good muffler shop near you that could help you out. They can weld on new O2 sensor bungs for you.
Sean bought a set of headers but it ended up being the wrong one for the California spec 4runners with 2 catalytic converters. I imagine we'll do this job at some point. Thanks for the comment.
Huh I hadn't heard that was an issue. I did hear guys like the TRD headers, was that what you guys were trying to install? I'm in Vallejo not all that far from your guys really so these restrictions also apply to me.
Well, I'll have to ask Sean for sure but I remember him saying he did get the wrong headers. California spec 4runners come with 2 catalytic converters and when we looked at the passenger side header, there' wasn't a way to attach both catalytic converters so we abandoned the project. We were thinking of installing the headers while we had Sean's transmission out of the way which would make it easier to get that exhaust cross pipe out that goes between the engine and transmission.
From my research of the first gen tacoma, which I think is very close to the same as a 3rd gen 4Runner front half, it doesn't seem easy AT ALL. seems like most people have to spend an entire day trying to cut the manifold out in order to then take another day putting the headers in, and on top of that 2002 models need to be welded also, apparently.
The 1st Gen Tacomas and 3rd Gen 4runners are exactly the same. And yes, I've heard it's a pain in butt. With it being a hard install, I just don't know if it's worth it.
Another great video Very detailed and learned something new. Was going to buy a tap and die set to clean up threads but will try a set similar to yours. I also have a little 3/8 stubby ratchet from Carlyle. Best little tool ever, especially when working on the V6 Tacoma engine.
Thanks Don, we're glad you like the video. The stubby ratchets are very handy. I love my Gear Wrench flex head stubby ratchet. I use it all the time. Thanks for taking the time to comment.
Time to replace my 02 3rz header. Was going to swap with a brand new OEM from Toyota but aftermarket headers caught my attention. It’s rare to find a direct fit Doug Thorley header, but if I did, is it worth it? I’ve read it can add a some extra low-mid power but I’m curious if it’ll cause issues with the fuel/air ratio?
Yep, we've heard this before. We're going to keep making videos so hopefully the next time you need to do something we'll already have a video for you to follow. Happy Wrenching!
Nice video! Very informative. I am getting ready to instal some Doug thorley headers on my 01 4runner V6. The headers came with some 1 piece header bolts, and I was wondering if it would be a better ideal to use the factory style 2 piece header bolts?
Hey John, installing headers on the V6 is quite a bit more involved and maybe you know that already. As for the bolt choice, I don't know enough about it to give you an informed opinion.
Are you able to use this particular header for a 2003 2.4 l 2RZ-FE engine? I’m looking to upgrade but with OEM components. Thanks for the vids, very helpful 🤙🏼
Not sure. The engine we're working on is the 3RZ. I've honestly never heard anyone talk about the 2RZ engine. I looked it up and apparently it came on 2wd 1st Gen Tacomas. Interesting. I'm guessing this was an option not many buyers chose.
Another awesome video! Question: Exhaust manifold stud replacement: what is correct part number (toyota OEM) for the exhaust bolt-stud that screws into the cylinder head? I see i video that you used existing studs which worked a-ok with the mini header. If i need to replace a stud, would these be same as the studs used on my 2002 4runner (3.4L)?
Hey Robert, glad you like the video. Not sure on the part number for the studs and whether or not they are the same for the 3.4 liter V6 engine. You could go to your local Toyota dealer or buy them from a Toyota engine rebuilder like Yota1 Performance. I'm guessing they won't be that expensive.
Great inform video. Question. I have 1999 t4r v6 dual cat ). I put trd headers on., but the down pipe not same angle as front cat. #1 Should I put a aftermarket front cat to get the straight angle. #2 Go 1 cat. Or back to stock manifold.
are you referring to the y-pipe that joins the headers to a single pipe which in turn bolts to the first CAT?... there seems to be different Y-pipes that would be plug n play but because those headers are long discontinued I'm not sure if you'd be able to find that piece anymore. I would not get an aftermarket CAT if you could help it. It may require a shop to cut & weld the old stock flange on the new TRD headers so it is an easy bolt up situation.
@@TimmyTheToolman, thanks for reply. yes the Y pipe that bolts to first cat. The cat has 3 hole flange. Trd headers has 2 hole flange. I had headers pulled off a 98 v6, which had a single cat. That bolted straight angle to Y pipe. The 99 catalytic angle upward. Thanks
We've only removed exhaust manifolds from the 5VZ-FE engine with it out and on a stand. If you're looking for a video to install headers, that's a video we'll probably never make. To get the crossover section in, either the engine or transmission would have to come out or at least partially out. It's quite a bit of work for negligible benefit. We do have videos showing how to remove the engine and the transmission, so if you were looking to install headers, you could consult those.
@@TimmyTheToolman Thank Timmy, as always most aprieciete. Most likely I am having a leak so I will need to do this anyway in nearest future. Just going throuh options. Most likely I will need help from prof garage. Was wondering though if I could do this in my garage by mysefl.
@@Amraam23 Yeah, you could do it yourself, but like I said, the crossover section that joins the two sides behind the engine will be impossible to get out unless you remove the transmission out of the way, or lift the engine away from the transmission. It depends how much a shop will charge you compared to you buying the tools necessary to do it on your own. An engine hoist is needed to lift an engine out and a transmission jack is ideal for removing a transmission. If I were going to do this job, and I had a 2wd 4runner, I'd remove the transmission. If I had a 4wd 4runner, I'd pull the engine. The 4wd with the transfer case makes it more work to pull the transmission. If you try to drop the transmission and transfer case as one unit, it's a very heavy and awkward assembly to deal with. I would pull the transfer case off the transmission first, but that's more time. Here's our Part 1 of our Transmission Replacement series so you can see the amount of work required. ua-cam.com/video/oZDSjlxl2Q4/v-deo.html Here's Part 1 of our Engine Replacement Series which shows us pulling a 5VZ-FE engine: ua-cam.com/video/0EtZnqzJhI4/v-deo.html
Hey Timmy! What would be the symptoms of a cracked exhaust manifold? Same exact 4Runner is dying on me and stalling on cold starts, wondering if this is the issue…
You would just have an exhaust leak, and you'd hear it. They usually make a tapping sound. Sounds like you might have an issue with your IAC (Idle Air Control) valve.
So I have a 96 4 runner 3rz engine . I have been looking for carb legal headers and none are aplicable for my year , so I was gonna do the Doug thorley headers for a 2001-04 Tacoma/4Runner , after talking to them (Doug thorley support) they informed me to talk to smog ref (I live in California) to make sure they would give me the ok for the headers . So I talked to the state ref and said that no they would not work so I asked if I could install the factory steel header offered for the 200-04 Tacoma/4Runner they said nope because it wasn’t made for my vehicle even though as u see in the video everything is a direct bolt on . I know that it’s at our own risk to do any mod , but dang really California !! There is no deference in the headers !!!
Nestor, California is a total joke when it comes to smog laws. Why do they care what exhaust you have on your vehicle? Why would they even care if you did an engine swap. If the vehicle passes the test of what's coming out the tail pipe, that's all that should matter. I've heard of people failing a "visual" inspection because the smog tech found a cracked vacuum hose. It's pretty freaking ridiculous. If the goal is to help keep our air cleaner, why do they care about this trivial stuff? The regulations in California are always going to be ridiculous and you can put the blame on the political party that has controlled this state for far too long.
The manuals are just Toyota Service Manuals and there's no part number that I know of. All you have to do is go on Ebay and do a search for the manuals for your year and model and you will most likely find a used set for sale. The going prices seem to be between $150-$300 for the two volume set.
Whether it makes a performance increase depends on who you ask. I think any performance increase is perceived rathe than actual. I think the main benefit to these headers is they aren't known to crack like the OEM exhaust manifolds are known for.
I unfortunately have very limited experience with the 3RZ engine. The only times I've worked on it was with my buddy Jordan and he moved back to Georgia. I don't know what that oil line is.
Looking to do this same swap on my 98. Wondering if the procedure is all the same since the Toyota part number is only "compatible" with the '99+ 3rd gens. The exhaust tick from my cracked cast iron header is driving me insane lol
I asked in the 3rd gen mafia group, seems they made it that way because it wasn't an original part for the earlier models. Weird they wouldn't say it still works with the older engines. I still hold to this day that watching a 15 minute video pains me, but watching a 1 hour or longer video of yours is so easy to do 😂 keep up the awesome content!
Yeah, that would have been something good to add to the video. To let you know, it didn't really sound much different. It's not like it use to be with adding a set of headers to a muscle car where it sounded way different afterwards.
Hey timmy have you ever replace headers on sr5 v8 i have the same problem with my 08 4.7 v8 headers are cracked somewere im about try change them with aftermarket headers but my concern is check engine and emission test
Would this fit a 1998 2.7 Tacoma? I typed in the part number for the headers and it says only for the year 2000? I’d assume it’s all the same but correct me if I’m wrong. Thanks!
Timmy The Toolman, do you happen to know the part number for the heat shield just above the catalytic converter? the one that is attached to the under body of the truck, you can see it right above the cat at 49:31. A mechanic who replaced the catalytic converter on my truck got rid of it and just like any other part, it happens to be very functional. Thanks in advance.
royaloreca Sorry but I don't know the part number for that. I'd look at online Toyota part seller's for their parts schematics and see if you can find it. If you come.up empty, try contacting Amanda at Camelback Toyota online parts sales. Amanda is usually very helpful and maybe she'll be able to hook you up. Their prices on parts are very competitive too. If that doesn't work, you might have to resort to visiting your local Toyota dealership and pay a little more for the part. But, you could also visit a local wrecking yard or PickNPull and see if you can find that heat shield on a salvaged 3rd Gen 4runner. Good luck!
Look at the parts list we show at 7:27 play time. It lists all the part numbers. I just did a search for the exhaust manifold and found it still available for sale.
I can't remember what that heat shield is protecting. I don't know if you'll regret your decision to leave it off or not. If it were me, I'd put it on.
@@TimmyTheToolman yeah ima put it on, only thing i can think of is the intake tube which is flexy and can deteriorate. Theyre just expensive 100$, ima just keep my eyes open for one at a junkyard part out. thx tim
@@yotagang3705 No problem. There is a guy in Washington that parts out 4runners. His name is Josh Young and he runs a business called PNW 4runner Connection. You can contact him via Facebook. He might have one he can sell you for a fair price. facebook.com/josh.young.3950
It's much much much harder on the 5VZ-FE. There's two manifolds to deal with and then the crossover pipe is next to impossible to get out unless you disconnect the transmission. I think people who do it without disconnecting the trans end up cutting the crossover pipe out because that's the only way they can get it out.
Timmy The Toolman we might not have that problem oz our exhaust runs under the transmission pan we to drop the exhaust just to do the filter on our pan
Hey Timmy so basically I was watching this to put in two new exhaust gaskets where the manifold and the flange connect. I found that I have an exhaust leak there. I was able to get all three bolts off, only 2/3 studs. One of the studs the etorx was stripped. Any recommendations on how I can proceed
I would first try to cut new threads with a die from a tap and die set. You have to first figure out what size and thread pitch it is and then get a die on there and start cutting new threads. This will most likely work if there's enough metal left on the stud. If it doesn't work, you can try to remove the stud from the exhaust flange but this will probably prove to be very difficult because they get really welded into the flange. You could treat it with some penetrant, then maybe use a butane torch to heat the flange around the stud and then get onto it with an e-torx socket and try to remove it. Your local Toyota dealer should be able to get you another stud. If that doesn't work and maybe the stud brakes off, then you left with drilling it out as carefully as you can, retapping the threads on the flange and installing an new stud. I hope this helped you out and let me know how it goes with fixing this problem.
@@cocopuffs6511 Are you talking about the studs we install at play time 43:14? If so, did the female threads in the header strip along with the male stud threads?
@@cocopuffs6511 So, you stripped the e-torx head installing the new stud into the header? Or, did you buy a used header and were trying to renew the studs? Jordan's new header didn't come with any studs installed so that's why I'm asking.
Hey Mike, I was mistaken about the comment about the paint. I mistook your comment for somebody who was commenting on a different video. As far as I know, the paint on Jordan's header is holding up just fine. As for the gasket, I don't think it's the same gasket. However, when you get the header, it should come with a gasket.
I don't understand what skeet shooting has to do with this video but I'll play along. Where do you live? I use to go skeet shooting when I was a kid. I haven't done it for probably 30 years.
Jordan had a "Phoenix Trap and Skeet Club" shirt on. I also haven't shot skeet for many years. The places where I used to go are gone or are heavily restricted. e.g. steel shot only which is a no-go for the number of rounds you put through a target shotgun. So-Cal. Off-topic, I know.
Norwegian language lessons. That's a first on our channel. To say goodbye, we usually say, "Later Dude". We are Coastal Californias and need to keep up the Surfer Dude image even if we aren't surfers.
I did this on my 98 back in the day. Was about as fun as wrestling a fat chick. When my OEM one came out it was literally in 2 pieces it was cracked so bad. I replaced it with a Tri-Y header from Northwest Off-road and picked up 2mpg.
Motor oil on exhaust studs is a big no no. Only use high temp thread locking compound, which actually does make removal easier even though it's chemically locking the stud and the head together, or a high quality anti seize. Great video otherwise. Keep them coming.
Well, we live in the People's Republic of California and there's pretty darn strict emission laws here. He could possibly fail the "Visual" Inspection during a Smog Check with the EGR missing.
California could be it's own country based off how different it is from most of the United States. I still like living here but it's getting harder and harder to stay.
What I'd like to know is...why the hell has the price of this OEM exhaust manifold gotten so expensive? It's absurd that any company is charging nearly $250 for a part that only cost $187 a couple years ago. There is nothing special about this part. I've paid less for a performance header for a 6 cylinder engine. I think the OEM headers for the 6-cylinder Tacoma are cheaper than this part cost now. Someone is definitely price gouging their customers.
Yeah, it's weird how the prices can fluctuate so much. Don't know if it's truly price gouging or not. If you want to see something even more ridiculous, go on Craigslist and see what people are asking for old land cruisers now. The FJ40s and FJ60s are ridiculously high. I had a 68 Bronco in high school and thought it would be cool to own one again. You can't touch a decent one for under 20k. Whoever is paying anything close to these asking prices has got to be nuts.
@@TimmyTheToolman You want to know what it is really? It's something that the general public is struggling to understand...the disparity between the wealthy and middle class is getting too big. There are just enough people who have too much money (or kids that spend their parents money- either from allowances or living with their parents until they're in their 30's skirting responsibilities) that companies know they can charge ridiculous prices and someone will pay it. Instead of making money from selling quantity they want to make more money selling less. The laws of supply and demand are getting twisted.

Well Dude, we gear our videos to the absolute beginner because we want the broadest audience to be successful following our tutorials. Things that you might think are very basic to know might not be apparent to a person just starting to turn wrenches. We all start somewhere. Try to remember when you first started turning wrenches and how little you knew. Sean and I believe auto mechanics is something anyone can learn if they truly want to. People regularly tell us how they appreciate the detail our videos offer and let us know that our videos empowered them to do a job they wouldn't have tried to tackle because they thought it was beyond their capability. So, you're entitled to your opinion but we're going to keep making videos how we like. The beauty of these videos is nobody is holding a gun to your head to watch the whole thing. You can fast forward to the parts you want to see and skip the rest. There have been experienced mechanics who have told us they appreciate the level of detail and information we provide in our videos. We realize our videos aren't for everyone and that's ok.

Hey Tim, How are you brother? I noticed that you don't have too many videos on the 3rd gen 4runner exhaust system. So, I'll ask this question since your videos are the ones that get me through these repairs. I have a 99 4runner 3.4 w/federal emissions.

Yes, those nuts are 14mm.
The exhaust studs turn into the exhaust flange clockwise to tighten and counter clockwise to loosen. The one near the passenger frame is harder to deal with if it breaks because you can't get a straight shot at drilling it out so you can retap it.
Those studs can be really hard to get out. Even with heat and penetrant, you will most likely break some of them. You might want to remove the exhaust manifold if you have to drill any of them out.
Maybe you have a good muffler shop near you that could help you out. They can weld on new O2 sensor bungs for you.
Good stuff. Looking forward to one of you guys installing headers on the 5vzfe. Keep up the good work!
Sean bought a set of headers but it ended up being the wrong one for the California spec 4runners with 2 catalytic converters. I imagine we'll do this job at some point. Thanks for the comment.
Huh I hadn't heard that was an issue. I did hear guys like the TRD headers, was that what you guys were trying to install? I'm in Vallejo not all that far from your guys really so these restrictions also apply to me.
Well, I'll have to ask Sean for sure but I remember him saying he did get the wrong headers. California spec 4runners come with 2 catalytic converters and when we looked at the passenger side header, there' wasn't a way to attach both catalytic converters so we abandoned the project. We were thinking of installing the headers while we had Sean's transmission out of the way which would make it easier to get that exhaust cross pipe out that goes between the engine and transmission.
From my research of the first gen tacoma, which I think is very close to the same as a 3rd gen 4Runner front half, it doesn't seem easy AT ALL. seems like most people have to spend an entire day trying to cut the manifold out in order to then take another day putting the headers in, and on top of that 2002 models need to be welded also, apparently.
The 1st Gen Tacomas and 3rd Gen 4runners are exactly the same. And yes, I've heard it's a pain in butt. With it being a hard install, I just don't know if it's worth it.
Another great video Very detailed and learned something new. Was going to buy a tap and die set to clean up threads but will try a set similar to yours. I also have a little 3/8 stubby ratchet from Carlyle. Best little tool ever, especially when working on the V6 Tacoma engine.
Thanks Don, we're glad you like the video. The stubby ratchets are very handy. I love my Gear Wrench flex head stubby ratchet. I use it all the time. Thanks for taking the time to comment.
Time to replace my 02 3rz header. Was going to swap with a brand new OEM from Toyota but aftermarket headers caught my attention. It’s rare to find a direct fit Doug Thorley header, but if I did, is it worth it? I’ve read it can add a some extra low-mid power but I’m curious if it’ll cause issues with the fuel/air ratio?
It won't cause any issues with the air/fuel ratio. I think the headers are less likely to crack so it's probably worth it.
i wish i this video would have been posted when i did this same job a couple of months ago, would have saved me some trouble.
Yep, we've heard this before. We're going to keep making videos so hopefully the next time you need to do something we'll already have a video for you to follow. Happy Wrenching!
Really wonderfully done tutorial!!
Thanks Mike. We're glad you like it.
Nice video! Very informative. I am getting ready to instal some Doug thorley headers on my 01 4runner V6. The headers came with some 1 piece header bolts, and I was wondering if it would be a better ideal to use the factory style 2 piece header bolts?
Hey John, installing headers on the V6 is quite a bit more involved and maybe you know that already. As for the bolt choice, I don't know enough about it to give you an informed opinion.
Timmy The Toolman Oh yea, the v6 is definitely more involved! Thank you for the feedback!
Are you able to use this particular header for a 2003 2.4 l 2RZ-FE engine? I’m looking to upgrade but with OEM components. Thanks for the vids, very helpful 🤙🏼
Not sure. The engine we're working on is the 3RZ. I've honestly never heard anyone talk about the 2RZ engine. I looked it up and apparently it came on 2wd 1st Gen Tacomas. Interesting. I'm guessing this was an option not many buyers chose.
Another awesome video! Question: Exhaust manifold stud replacement: what is correct part number (toyota OEM) for the exhaust bolt-stud that screws into the cylinder head? I see i video that you used existing studs which worked a-ok with the mini header. If i need to replace a stud, would these be same as the studs used on my 2002 4runner (3.4L)?
Hey Robert, glad you like the video. Not sure on the part number for the studs and whether or not they are the same for the 3.4 liter V6 engine. You could go to your local Toyota dealer or buy them from a Toyota engine rebuilder like Yota1 Performance. I'm guessing they won't be that expensive.
Timmy!!!! Do you have a video replacing a 3RZ oil pump???
Sorry Nicholas, we don't have a video for that unfortunately.
Great inform video. Question. I have 1999 t4r v6 dual cat ). I put trd headers on., but the down pipe not same angle as front cat. #1 Should I put a aftermarket front cat to get the straight angle. #2 Go 1 cat. Or back to stock manifold.
are you referring to the y-pipe that joins the headers to a single pipe which in turn bolts to the first CAT?... there seems to be different Y-pipes that would be plug n play but because those headers are long discontinued I'm not sure if you'd be able to find that piece anymore. I would not get an aftermarket CAT if you could help it. It may require a shop to cut & weld the old stock flange on the new TRD headers so it is an easy bolt up situation.
@@TimmyTheToolman, thanks for reply. yes the Y pipe that bolts to first cat. The cat has 3 hole flange. Trd headers has 2 hole flange. I had headers pulled off a 98 v6, which had a single cat. That bolted straight angle to Y pipe. The 99 catalytic angle upward. Thanks
Very nice. Where or when can I see same procedure on 5vz-fe engine?
We've only removed exhaust manifolds from the 5VZ-FE engine with it out and on a stand. If you're looking for a video to install headers, that's a video we'll probably never make. To get the crossover section in, either the engine or transmission would have to come out or at least partially out. It's quite a bit of work for negligible benefit. We do have videos showing how to remove the engine and the transmission, so if you were looking to install headers, you could consult those.
@@TimmyTheToolman Thank Timmy, as always most aprieciete. Most likely I am having a leak so I will need to do this anyway in nearest future. Just going throuh options. Most likely I will need help from prof garage. Was wondering though if I could do this in my garage by mysefl.
@@Amraam23 Yeah, you could do it yourself, but like I said, the crossover section that joins the two sides behind the engine will be impossible to get out unless you remove the transmission out of the way, or lift the engine away from the transmission. It depends how much a shop will charge you compared to you buying the tools necessary to do it on your own. An engine hoist is needed to lift an engine out and a transmission jack is ideal for removing a transmission.
If I were going to do this job, and I had a 2wd 4runner, I'd remove the transmission. If I had a 4wd 4runner, I'd pull the engine. The 4wd with the transfer case makes it more work to pull the transmission. If you try to drop the transmission and transfer case as one unit, it's a very heavy and awkward assembly to deal with. I would pull the transfer case off the transmission first, but that's more time.

Did this job on my 99 taco several years ago, I got a junkyard header for $80, think it came off a 03 maybe.
That was a good find. Sean and I also visit our local PickNPull yards to grab parts.
What all models have these mini headers if I looking for a used set in a pull-a-part junk yard.......?
Not sure. Jordan bought his headers brand new.
Hey Timmy! What would be the symptoms of a cracked exhaust manifold? Same exact 4Runner is dying on me and stalling on cold starts, wondering if this is the issue…
You would just have an exhaust leak, and you'd hear it. They usually make a tapping sound. Sounds like you might have an issue with your IAC (Idle Air Control) valve.
So I have a 96 4 runner 3rz engine . I have been looking for carb legal headers and none are aplicable for my year , so I was gonna do the Doug thorley headers for a 2001-04 Tacoma/4Runner , after talking to them (Doug thorley support) they informed me to talk to smog ref (I live in California) to make sure they would give me the ok for the headers . So I talked to the state ref and said that no they would not work so I asked if I could install the factory steel header offered for the 200-04 Tacoma/4Runner they said nope because it wasn’t made for my vehicle even though as u see in the video everything is a direct bolt on . I know that it’s at our own risk to do any mod , but dang really California !! There is no deference in the headers !!!
Nestor, California is a total joke when it comes to smog laws. Why do they care what exhaust you have on your vehicle? Why would they even care if you did an engine swap. If the vehicle passes the test of what's coming out the tail pipe, that's all that should matter. I've heard of people failing a "visual" inspection because the smog tech found a cracked vacuum hose. It's pretty freaking ridiculous. If the goal is to help keep our air cleaner, why do they care about this trivial stuff? The regulations in California are always going to be ridiculous and you can put the blame on the political party that has controlled this state for far too long.
Any carb legal header is LEGAL, that smog ref is an idiot , contact LCE performance they have carb legal headers for your 3rz
Hello Timmy,
Thanks for the video.
Can you please provide the name and part number of the service manual, i would like to get one.
Thank you very much
The manuals are just Toyota Service Manuals and there's no part number that I know of. All you have to do is go on Ebay and do a search for the manuals for your year and model and you will most likely find a used set for sale. The going prices seem to be between $150-$300 for the two volume set.
Does this effect the car’s performance at all if you change to headers? Do you have to make any air ratio adjustments?
Whether it makes a performance increase depends on who you ask. I think any performance increase is perceived rathe than actual. I think the main benefit to these headers is they aren't known to crack like the OEM exhaust manifolds are known for.
@@TimmyTheToolman thank you for the reply I appreciate you! (:
@@Hellogoodbye_ You're very welcome!
Any multiple year follow up
Everything is fine. Jordan hasn't said his header has failed so I assume it's doing what it's suppose to.
That oil filler cap is cool, need to get my hands on one.
what is that solid oil line above the filter and also coming out of the block?
I unfortunately have very limited experience with the 3RZ engine. The only times I've worked on it was with my buddy Jordan and he moved back to Georgia. I don't know what that oil line is.
Looking to do this same swap on my 98. Wondering if the procedure is all the same since the Toyota part number is only "compatible" with the '99+ 3rd gens. The exhaust tick from my cracked cast iron header is driving me insane lol
I wonder why it says it's not for the earlier models. It's the same engine.
I asked in the 3rd gen mafia group, seems they made it that way because it wasn't an original part for the earlier models. Weird they wouldn't say it still works with the older engines.
I still hold to this day that watching a 15 minute video pains me, but watching a 1 hour or longer video of yours is so easy to do 😂 keep up the awesome content!
Would have like to hear it running when finished.
Yeah, that would have been something good to add to the video. To let you know, it didn't really sound much different. It's not like it use to be with adding a set of headers to a muscle car where it sounded way different afterwards.
Hey timmy have you ever replace headers on sr5 v8 i have the same problem with my 08 4.7 v8 headers are cracked somewere im about try change them with aftermarket headers but my concern is check engine and emission test
No, we haven't replaced headers on a Toyota 4.7 liter V8 yet.
Best channel on YT, hands down.
Thank You! That's a very nice compliment you have given us.
Would this fit a 1998 2.7 Tacoma? I typed in the part number for the headers and it says only for the year 2000? I’d assume it’s all the same but correct me if I’m wrong. Thanks!
I'm assuming it would work since they're all the same motor. It doesn't make any sense why it would only work for the 2000 model
@@TimmyTheToolman yep definitely thanks!
@ Timmy I just completed this last weekend. Thanks to you and Jordan the process made it really easy 👌🏼
Timmy The Toolman, do you happen to know the part number for the heat shield just above the catalytic converter? the one that is attached to the under body of the truck, you can see it right above the cat at 49:31. A mechanic who replaced the catalytic converter on my truck got rid of it and just like any other part, it happens to be very functional. Thanks in advance.
royaloreca Sorry but I don't know the part number for that. I'd look at online Toyota part seller's for their parts schematics and see if you can find it. If you come.up empty, try contacting Amanda at Camelback Toyota online parts sales. Amanda is usually very helpful and maybe she'll be able to hook you up. Their prices on parts are very competitive too. If that doesn't work, you might have to resort to visiting your local Toyota dealership and pay a little more for the part. But, you could also visit a local wrecking yard or PickNPull and see if you can find that heat shield on a salvaged 3rd Gen 4runner. Good luck!
My Tacoma 3RZFE came stock with the header instead of the cast iron manifold.
Well Wayne, I reckon you lucked out. Do you think it was an option back then?
Cant seem to find the header you guys used!
Look at the parts list we show at 7:27 play time. It lists all the part numbers. I just did a search for the exhaust manifold and found it still available for sale.
i did this healthy mod aswell but i didnt put the heat shield….what are the consequences of not putting it on?
I can't remember what that heat shield is protecting. I don't know if you'll regret your decision to leave it off or not. If it were me, I'd put it on.
@@TimmyTheToolman yeah ima put it on, only thing i can think of is the intake tube which is flexy and can deteriorate. Theyre just expensive 100$, ima just keep my eyes open for one at a junkyard part out. thx tim
@@yotagang3705 No problem. There is a guy in Washington that parts out 4runners. His name is Josh Young and he runs a business called PNW 4runner Connection. You can contact him via Facebook. He might have one he can sell you for a fair price. facebook.com/josh.young.3950
Should do this for the 5vzfe!
It's much much much harder on the 5VZ-FE. There's two manifolds to deal with and then the crossover pipe is next to impossible to get out unless you disconnect the transmission. I think people who do it without disconnecting the trans end up cutting the crossover pipe out because that's the only way they can get it out.
Timmy The Toolman we might not have that problem oz our exhaust runs under the transmission pan we to drop the exhaust just to do the filter on our pan
@@lukeneave Gotcha, that sounds much easier. It is still a fair amount of work and I wonder if it's worth the effort.
Hey Timmy so basically I was watching this to put in two new exhaust gaskets where the manifold and the flange connect. I found that I have an exhaust leak there. I was able to get all three bolts off, only 2/3 studs. One of the studs the etorx was stripped. Any recommendations on how I can proceed
I would first try to cut new threads with a die from a tap and die set. You have to first figure out what size and thread pitch it is and then get a die on there and start cutting new threads. This will most likely work if there's enough metal left on the stud. If it doesn't work, you can try to remove the stud from the exhaust flange but this will probably prove to be very difficult because they get really welded into the flange. You could treat it with some penetrant, then maybe use a butane torch to heat the flange around the stud and then get onto it with an e-torx socket and try to remove it. Your local Toyota dealer should be able to get you another stud. If that doesn't work and maybe the stud brakes off, then you left with drilling it out as carefully as you can, retapping the threads on the flange and installing an new stud. I hope this helped you out and let me know how it goes with fixing this problem.
Doesn’t the stud move right through the flange? Cause I’m the vid you guys pulled out the. Manifold with the studs still attached
@@cocopuffs6511 Are you talking about the studs we install at play time 43:14? If so, did the female threads in the header strip along with the male stud threads?
Luckily no, the star of the bolt stripped and I’m unable to get it out of the header
@@cocopuffs6511 So, you stripped the e-torx head installing the new stud into the header? Or, did you buy a used header and were trying to renew the studs? Jordan's new header didn't come with any studs installed so that's why I'm asking.
Hi guys. I'm having trouble locating a steel header like this. Can you give me a part number or the site you purchased this from? Thank you
store.torfab.com/category-s/2067.htm
Thank you for the reply. How's the paint holding up?
Sounds good. Are the gaskets the same as the stock cast iron manifold? Thanks again for the replies
Hey Mike, I was mistaken about the comment about the paint. I mistook your comment for somebody who was commenting on a different video. As far as I know, the paint on Jordan's header is holding up just fine. As for the gasket, I don't think it's the same gasket. However, when you get the header, it should come with a gasket.
Lets go skeet shooting man.
I don't understand what skeet shooting has to do with this video but I'll play along. Where do you live? I use to go skeet shooting when I was a kid. I haven't done it for probably 30 years.
Jordan had a "Phoenix Trap and Skeet Club" shirt on. I also haven't shot skeet for many years. The places where I used to go are gone or are heavily restricted. e.g. steel shot only which is a no-go for the number of rounds you put through a target shotgun. So-Cal. Off-topic, I know.
Roger that. I was wondering where that comment came from.

Tim how can i send you a video of my Tacoma
You can send to my email address: mtbtim@sbcglobal.net
I did this on my 98 back in the day. Was about as fun as wrestling a fat chick.
When my OEM one came out it was literally in 2 pieces it was cracked so bad.
I replaced it with a Tri-Y header from Northwest Off-road and picked up 2mpg.
Yeah, working with exhaust is usually not a fun experience because the bolts and nut always fight you.
Motor oil on exhaust studs is a big no no. Only use high temp thread locking compound, which actually does make removal easier even though it's chemically locking the stud and the head together, or a high quality anti seize. Great video otherwise. Keep them coming.
Thanks for the comment.
Why did he reinstall the EGR? Delete that!
Well, we live in the People's Republic of California and there's pretty darn strict emission laws here. He could possibly fail the "Visual" Inspection during a Smog Check with the EGR missing.
Timmy The Toolman oh... that sucks... up here in Warshingtonia, we have no such thing.
California could be it's own country based off how different it is from most of the United States. I still like living here but it's getting harder and harder to stay.
You don't have one video like this for the 3rd gen 4runner v6? I think mine has leaks
Hey Jorge, no we don't have a video for the V6 yet.
What I'd like to know is...why the hell has the price of this OEM exhaust manifold gotten so expensive? It's absurd that any company is charging nearly $250 for a part that only cost $187 a couple years ago. There is nothing special about this part. I've paid less for a performance header for a 6 cylinder engine. I think the OEM headers for the 6-cylinder Tacoma are cheaper than this part cost now. Someone is definitely price gouging their customers.
Yeah, it's weird how the prices can fluctuate so much. Don't know if it's truly price gouging or not. If you want to see something even more ridiculous, go on Craigslist and see what people are asking for old land cruisers now. The FJ40s and FJ60s are ridiculously high. I had a 68 Bronco in high school and thought it would be cool to own one again. You can't touch a decent one for under 20k. Whoever is paying anything close to these asking prices has got to be nuts.
@@TimmyTheToolman You want to know what it is really? It's something that the general public is struggling to understand...the disparity between the wealthy and middle class is getting too big. There are just enough people who have too much money (or kids that spend their parents money- either from allowances or living with their parents until they're in their 30's skirting responsibilities) that companies know they can charge ridiculous prices and someone will pay it. Instead of making money from selling quantity they want to make more money selling less. The laws of supply and demand are getting twisted.

You really dont have to explain every detail. Explaining how to clean a stud with a wire brush or how to remove a gasket is common sense and if its not then maybe your viewers shouldnt be attempting something like they dont have basic mechanic knowledge. Just my opinion
Well Dude, we gear our videos to the absolute beginner because we want the broadest audience to be successful following our tutorials. Things that you might think are very basic to know might not be apparent to a person just starting to turn wrenches. We all start somewhere. Try to remember when you first started turning wrenches and how little you knew. Sean and I believe auto mechanics is something anyone can learn if they truly want to. People regularly tell us how they appreciate the detail our videos offer and let us know that our videos empowered them to do a job they wouldn't have tried to tackle because they thought it was beyond their capability.
So, you're entitled to your opinion but we're going to keep making videos how we like. The beauty of these videos is nobody is holding a gun to your head to watch the whole thing. You can fast forward to the parts you want to see and skip the rest. There have been experienced mechanics who have told us they appreciate the level of detail and information we provide in our videos. We realize our videos aren't for everyone and that's ok.
As someone who just bought a 96 Tacoma and is replacing a cracked manifold, I’ve gotta say that explaining every little detail has been very helpful for me. This video has helped me out so much, thank you!
