01 TOYOTA SEQUOIA TUNDRA 4.7 EXHAUST MANIFOLD LEAK

[@aaronbradley4361]

I have a 2003 Sequoia with 421,000 miles. Original motor. These are some of the best motors ever made. They were developed for Lexus with the ls400. Also, very easy to work on

[@rcolon5432]

Nice contribution on the fix of the ticking sound & location of the manifold.

[@Bohnfire]

Nice job showing a manifold repair. I’m a Toyota certified expert mechanic, and I’ve never seen a head gasket go bad on the 4.7. They are one of the best engines that Toyota made in my opinion. It sounds like they might not of had the correct antifreeze in there. It also should be changed every 100k, or with the timing belt job. One time I saw the manifold being welded on the truck to fix the same problem. I also put on some aftermarket shorty headers before. They usually need a slight modification to get the exhaust to bolt on. Nice job

[@bubbieallen795]

Mikael Bohn I have a 2007 that’s ticking if I don’t fix this problem as this guy did in the video what will happen will I blow a head gasket?

[@CurtisL8.3066]

Hey I know this was 4 years ago, but you said they welded the manifold on the truck? Did you see it get done? How sketchy on a scale 1-10 was it? Lol

[@Bohnfire]

@@CurtisL8.3066 a guy a couple bays down did it on his own 4Runner. He had the truck running and made a series of tack welds until the leaking stopped

[@jasonallenperry]

I just searched is there anyway to patch the manifold for a GEN one Toyota Sequoia, and your video came up. Your content was exactly perfect for my situation! I hope yours is still truckin’ ride along brother! I paid $3800 for mine and it was garage super clean interior and rides like it’s brand new! I’m dealing with the idler pulley, which may have caused my throttle body to spew some coolant. I figured I’d take care of all the issues at once. I heard the ball joints go bad so I’m gonna go ahead and replace those they don’t seem to be an issue. Thanks again!

[@BigBooBooDaddy]

Great video and great information. I was hesitant to fork out $400/side for factory manifolds. Now I'll try having them welded. What a savings! Thanks for posting.

[@JoshuaCrunk]

Really excellent video. Haven't found another describing the problem as well as this one in the 8 years since you made it.

[@markchamberlin3741]

Thank you so much!! That trick with the end wrench and pry bar worked like a bloody charm! Wouldn't have thought of it.

[@Clevelandsteamer324]

Unusual for this motor. Multiple examples with million miles

[@lynneb.9564]

Thank you. I was trying to learn where the 02 sensor was located on the exhaust manifold. Your video was great.. pleasantly humble and helpful with the machine shop tip if the manifold shows signs of leakage.

[@2ShoesPhoto]

Mine started as only when it was cold and now it's just loud all the time. My truck has 410K miles on her so I'm not too worried so I'll be looking into fixing it soon.

[@SpaceTurkey_33]

Thanks for taking the time to make this. Just saved me some money. Appreciate it.

[@bigtater29]

thanks a lot. I just picked up a 2000 tundra. same problem but it's at the more advanced stage, where it doesn't go away. great video. I'm gonna get on it. :-)

[@mameryjazz]

hi. did you fix your tundra manifold? the noise on my 2005 sequoia does not go away either. is it doable from the top or bottom of the vehicle?

[@0537059]

Doug thorley header! Fixed mine and added 30hp to the wheels. I also added a Doug Thorley cat back.

[@chrisdreyer8747]

Thanks for the video and tips, my 2004 Sequoia has the same issue at 126,000.

[@bradwallace60]

Thanks... I have been wanting to address this on my 2004 Tundra Double Cab. 141,000 miles...

[@sicchuckie]

Thanks for tip. Anyway to keep it from blowing a head gasket?

[@sverl100]

Thank you, now i understand the tick in my Tundra

[@modus19]

Good video. Always thought this was the problem on my 03 Tundra. Now I know exactly where to look. Haven’t heard it loud in a few years though. Assuming it’s been carboned over

[@randalln.587]

Getting ready to do my 01 4.7 been driving it like this for 90k + lol. Thankyou

[@mdrobnson3912]

Toyota does seem to make solid products Had a 98 Corolla Kept it in the road for 17 years, 300K miles, head to replace the front CV axles six times and the starter twice. Absolutely no problems otherwise until the transmission blew and we just decided to upgrade to a larger vehicle. The one major problem Toyota had imo it's the door handles are just crap. I've not owned one vehicle without at least one that want broken already My last one, 92 Camry had for broken inside and three outside Wife's 04 Camry had as a broken interior handle But opening the door don't count, keeping it in the road is where they earn they're reputation with me and that they do quite well. Just bought an 01 Sequoia and it has the exhaust leak also. It has some cosmetic issues but this seems to be the only mechanical issue this far. Guy gave me the exhaust manifold, I just need it put on because I am not a car guy. I really wonder if the high temp jb weld would hold long enough for me to save up the money to get it done???

[@RushAustin]

Great video. Was it just the one port that needed welding? Thanks!

[@BrigT262]

Yes. Just that one front port. It totally fixed the problem.

[@triciaslinger2710]

im looking at buying a 2006 sequoia v8 looks, just like yours. 154k miles. when did your exhaust manifold go, and your head gasket go?

[@appleguy6708]

I got mine 226k for 5300 it’s 2021 333K love this BEAST God bless you bro

High Temp JB Weld should do

[@omarlawrence1846]

Hey ,t I noticed your hat,do you work for them as well...i could use your expertise ...im on foam operation ...

[@halfglassfull]

My 2007 Tundra has only 42k miles but started making the ticking sound and clatters when I accelerate. It is likely an exhaust manifold leak. Do you know if your manifolds are stainless steel? Thanks

[@danieljantz913]

I may have a leaking manifold. My engine has a tick when start it up and goes away after a few minutes but only does it when the air temp is below 32°. Does a leaky manifold hurt engine performance?

[@kengoessling8449]

Great idea to get machine shop to fix. I found Dorman manifolds 674684(left) and 674683 (right) on rockauto.com for $133 each. My mechanic says he can't buy them that cheap and Dorman reengineers them so they don't fail again. Dealer wants $1100 to replace one. One guy I asked says 7hrs per side. Another says 5. Labor rate at dealer is $134. My guy is $99 at 5 hrs.

[@chieflouie2821]

I did a replacement on my Celica and I overtightened my exhaust studs. This caused the head to crack and leak coolant.

[@josephlecheminant2231]

Would it work well enough to apply some exhaust cement paste to the cracked areas instead of welding?

[@BrigT262]

No. I'm afraid not. I would think that stuff would burn off after awhile. Much better to have a shop weld it back up.

[@callmebigpapa]

KZbin gold right here!

[@jimtrook3597]

I had run into an exhaust leak on one of these engines, but as I recall it had the cast iron manifold. Not sure what year it was. The leak turned out to be poor machining on the flange area where it fits to the exhaust port. It was an obvious factory defect.

[@bigc6886]

I have a 2000 Tundra I have the same symptoms coming from my exhaust manifold on the passenger side. But my tick does not go away after warming up, could that be because the exhaust may have larger cracks/holes in the manifold? I'm hoping it is not a valve issue.

[@BrigT262]

cordon, you could pull off the valve cover and run the engine to identify it it's coming from the valve train. but I bet it is the ex manifold leaking. put some effort into it. you'll figure it out.

[@bigc6886]

Will do thanks.

[@BrigT262]

Yes that does sound like a valve train issue. I'd suggest pouring a qut of ATF in your oil and run that for 500 miles and then change your oil. I've done that several times over the yrs and it works!

[@eddieromero8161]

Do you have a video of how it sounds like?

[@bigtater29]

mamery jazz. it's doable but you have to hit it from about every angle. from underneath from above and through the fender well. my buddy just did his on his 2000 Tundra. but he replaced the manifolds with some aftermarket headers. as opposed to fixing his old manifolds which he actually gave me or buying new ones. The new headers were less than half the price of new yota manifolds. he said they were damn tight to get in. better sound and performance too.

[@mameryjazz]

BIGTATER thanks for replying. I got busy and took the car to a muffler shop to get a confirmation. They were in the hurry to replace both manifolds gaskets since no cracks were found in the manifold. Charged me $225 just to find out that the noise remains. I am so annoyed by it that I already put it on Craigslist for $6k. Mine has 140k miles. Thanks again for taking the time to reply.

[@bigtater29]

mamery jazz. that's sucks dude. I'm sorry to hear that. but if ur gonna sell it, put 7k on to. lol. It'll bring it.

[@mameryjazz]

+BIGTATER i did but issue is people are poor right now and waiting on income tax. I even lowered it to 5500 smdh. I am actually driving it now. that is the best i can do. At least im enjoying it lol

[@benheatherman2839]

We have a 2001 Toyota Land Cruiser with a 2uz-fe that just tuned 250k last weekend. it's had a leak for quite some time. This video was quite helpful. However i'm a bit paranoid that if I try to take it apart an exhaust stud will brake. So i'm going to hang off till I can't stand it.

[@0537059]

Don’t worry!!! I was the same way with my 2000 landcruiser. Just spray these studs and nuts with PB blaster for a few days and let it sit before you do the manifolds. If the nuts get stuck with rust it simply unthreads the studs out of the head. I think I used 12 new studs and all new nuts when I fixed my cracked manifold with headers :). Cheers!

[@altawatihamad1714]

Thanks for this video. l think the manifold is made from stainless steel, so I would like to know which type of welding you used.

[@like-mindedwellness7586]

Tig welding

[@chanelfierro7351]

So the manifold fix also helped the coolant leak? I have the same issue now with a flashing check engine and a bigger air leak 😭

[@Jdowling357]

Flashing check engine usually indicates a misfire

[@TeslaOverland]

Has it held? I heard welding them doesn’t last.

[@aaronbradley4361]

Sounds like you had a bad water pump and lost enough coolant to the point where the motor overheated and blew the head gasket. New denso radiator is about 150$$. I would recommend getting one and doing the water pump and timing belt on your replacement motor.

[@Operator-fq2fn]

Most likely over heated it

[@iddddaduncan]

How did this repair last?

[@brandon51541]

Excellent video. Do you still own it ??

[@BrigT262]

No. We've upgraded over the years. But, it was a great car!

[@darekski3406]

geat video and pointers,do you have a video how to replace cam shaft seals on a tundra v8 4.3l

[@BrigT262]

Sorry, I dont have that info.

[@narule2695]

Toyota doesn't have 4.3l. only 3.7l or 4.7l

[@wnorcott]

Excellent presentation thanks.

[@mameryjazz]

Thanks for posting this video. I have a leak in my 2005 Sequoia; however, it never goes away. Took it to a muffler shop; they think it is the manifold. I love do-it-yourself tasks but have to admit that this one is intimidating me because i can not think of a way to remove the complete exhaust. My question is: did you remove the manifold from under the vehicle or do you access its bolts from the top of the engine. Thanks in advance for assisting me so I know if it is doable for me or not.

[@BrigT262]

mamery jazz mostly the bolts are accessible from the bottom and through the inner fender. It might help to remove the wheel to have better access.

[@mameryjazz]

+Brig T Thanks Brig T. I had both manifold removed but i was unfortunate because we found no leak in my case. Replaced the gaskets just to find out that the noise is still there. Have no idea and gave up fixing it. I can only think about the throttle body plate although it may sound unlikely

[@tcepilot]

I have a 2002 4.7 tundra. Do I have to pull the motor go replace the manifolds?

[@BrigT262]

No. You don't have to pull the motor. It's not too bad of a job to do when the engine is in the car.

[@Dayamisita]

Thanks a lot , I have the same exact problem.

[@tamiyastars]

Good video, I also have this problem and also happen to eat fruity pebbles by the case lol.
