This is Part 3 of a 7 part video series documenting the replacement of cylinder heads on the Toyota 3.4 L V6 5VZ-FE Engine. There’s many reasons why you might find yourself needing to remove the heads. You could have a suspected bad head gasket or cracked head. You could have a suspected issue with the head, like a burnt valve, and you need to rebuild the head. It could be because you’re rebuilding the entire engine. Whatever your reason to pull the cylinder heads, this video series will walk you through all the steps necessary to get the job done successfully.
In Part 3, we continue with the engine tear down, doing everything necessary to finally pull the heads off the block. We start with getting things disconnected from the heads like the alternator & bracket, power steering pump & bracket, transmission dip stick tube, intake manifold, wiring harness, and exhaust manifolds. We next show the proper sequence to get the exhaust and intake cams off the heads. Finally, we show the proper loosening sequence to get the heads off the block.

Dear Timmy and Sean:
As a South African now living “Down Under”, thank you for taking much time and putting the effort into making this tutorial video set - to help others rebuild of their beloved Toyota 5vz-fe engine. This was a truly professional job! Without your dedication, I would have failed at saving my Landcruiser Prado. I am so grateful and wish you both all the best as you selflessly inspire others to do the same!
@@OlafNolle You're very welcome! We appreciate everything you wrote. Happy Wrenching!
It's worth repeating: You guys are hands down the VERY BEST channel for working on classic Toyota's. Best teachers on youtube. Your lesson in a previous video about servicing rear axle ( outer bearing/components replacement ) for a 2000 Tacoma, and how you discovered the best method for installing the new bearing retainer BACKWARDS for a better inner seal in that particular model, along with firsthand proof via a test you came up with using axle grease to see a witness mark, proved invaluable.
Thank you for the very nice compliment for our channel. We really appreciate it! It's guys like you that help fuel our desire to keep making videos. Happy Wrenching!
Hi again I’m very impressed about all the electrical connection in my 4 runner and the quality of them even though the quality of the screw is unbelievable. Thank you
Nice video, very informative as usual.
When I did the work on my engine I forgot to secure the power steering pump, I came back the next day and it had slipped and dumped all of the power steering fluid all over the drive way. I felt quite foolish as I was cleaning up the mess, because securing that was something that should have been obvious.
Also I too had a rough time with getting the exhaust manifolds free of the crossover pipe, I ended up taking them loose from the heads, taking the heads off, then taking the manifolds and crossover as a unit off. After I got it free from the vehicle, I was able to dismantle the crossover pipe from the manifolds on my bench.
Things happen and we all make mistakes. At least it wasn't a super costly mistake. Yeah, those exhaust manifold studs and nuts can be a serious pain in the butt. It was a frustrating day but we finished strong.
For me , after having removed the cross over pipe, removing both heads with the headers still attached ( down pipe disconnected) was the easiest way to remove them. Re installation was the same, install the exhaust manifolds to both heads and then re-install. Did my entire job using my Bendpak lift made the job much easier. Reinstalling that cross over pipe was a big pain in the butt though.
Thanks for the suggestion, Batman.
Nice I was just about to ask if it would be easier to leave exhaust manifolds on!
"This is not the time to be smokin' dope and jumpin' rope" 😂😂😂
Tim, you are the man. Thanks for all you do for the community. I'm doing my knock sensors, timing belt and water pump right now and your videos are hands down the best on UA-cam.
2000 4R SR5 still on the original timing belt, my water pump has a date of 8/99 cast on it, 24 years old, 220k and it isn't leaking. Toyota for life 💯💪😤
I'm glad you appreciate my commentary, and thanks for the nice compliment for our channel. Happy Wrenching!
Ya know what. I'll just buy a new engine when I get out of the military
My favorite channel !!
Thanks for being a fan!
Another great video I have no intention of removing my heads but watching you do it Tim is therapeutic
Thanks! We appreciate the compliment. I never knew our videos were therapeutic.
Tim, enjoyed this very informative video. Cheers, Mate.
Good to know Jack. Thanks!
Thank you for sharing every little details with us in the video.much appreciated teacher
You're very welcome. The detail shared in our videos is what separates us from the majority of DIY Automotive channels. We want people using our videos to be successful, and that's why we put the extra effort into them so even a beginner can follow along and complete the job. Thanks for the comment.
Great video guys.
Thanks Ben!
Yes yes great to see the cylinder heads come off! And the diag on the coolant loss, so quick after all the work you guys did. One question, I've read elsewhere that cracks can be repaired. In this case is it just not worth it, or does the location of the crack not allow a repair?
Yes, they can be repaired. The experienced machined at Yota1, this guy Allen, says he does repair cracks. But, once the cracks extend into a coolant jacket, he doesn't attempt to repair them.
Really impressed with this series I’d say better than chiggers. Those exhaust studs are evil though. In my case I was able to access all exhaust bolts without removing suspension components though I don’t recommend it.
Thanks for the compliment. We appreciate it! The Worse than Chiggers guy really did a great job with his series and he shot the whole thing alone. But yeah, ours is taking it to a higher level with the camera angles we can achieve due to Sean's expert filming, and the information we are imparting the viewer. You're gonna like Part 4. Stay tuned!
Dear Timmy how are you ? I’m more than glad to see your awesome videos , I’m in the middle of the process to change the head gasket and I’m doing because of your videos thanks so much for all your knowledge and for sharing all .The full injector did you know where Sean bought it I need to changed mine.Thank you and I hope you guys doing well .

I'm no hero. Just doing my part to help my fellow man.
Great video Tim, this Toyota engine is very reliable do you know what caused the cracked head?
Thanks! These heads can crack on any engine, but I suspect the supercharger has something to do with it.
Wow, thanks for taking the time to teach us so much.
My pleasure! Thanks for commenting.
Following you during this repair step by step. Very helpful! Where and what brand do you recommend for ordering the repair kit from? Apologies if you have covered that before! Just want something quality as this is a process that I don't want to repeat for a while.
This is the one we used: 209yota1.com/products/5vz-3-4l-cylinder-head-gasket-set-w-mls-head-gasket-1999-2004/ Don't know if there's a better option online.
Thank you so much for the information
You're very welcome.
Once again, awesome video! Could you tell me what repair manual that you have? I have searched online and I have found several, but I'm somewhat cautious that some aren't as informative as others, and I don't want to spend money on one that doesn't provide detailed information that I need. Thanks again.
What year and model rig do you own?

@@TimmyTheToolman Thank you sir for your help. When I have to work on my Tacoma, I always type in your name to see if you have a video on it. lol Thanks for making these videos for us weekend warriors. Take care!
Hi Timmy how are you buddy .thank you again for this amazing video ,I will like to ask a question in my 4 runner I see that the person that it work before didn’t put the screw in the camshaft and I can’t put the screw because isn’t aligned it ? What did you recommend thank you in advance
@@pepilloni I'm not sure exactly what you're asking for clarification on. Could you try explaining it again?
Great video or if i may say videos! All of these videos have been really helpful for me repairing my 3rd gen. Where can i buy that same service manual?
What year and model rig do you have?

@@sreyes1103 Hey Steven, you can usually find the factory service manuals for sale on Ebay. Here's one I found for you: ebay.us/SfGCeX
The first 4Runner I had as well as the one I have now both had bad passenger heads.
Interesting. I have also heard many failures on the passenger head, primarily the #3 cylinder.
@@TimmyTheToolman that’s where one of my failures were
@@Spaceberries12 Yep, seems to be common.
Are we able to check all the valve lash with the cams lined up at the dots?
No, you're not. You have to rotate the cams to different positions to check all the valve clearances. Check out this video: ua-cam.com/video/MOlmjtlO7TI/v-deo.htmlsi=aJLxRuLFcxesgLvg
Tim said “no smokin big fatties” lol
D.A.R.E. BEAR entered the chat.
Finally somebody comments about the humor. Thanks!
So on the passenger side cam caps the arrow points to the front of the engine as does the factory arrow on the cylinder head just near the #1 cylinder spark plug tube. Do the arrows on the driver side cam caps point towards the fire wall and not the front of the engine?
@@4phishn The driver side bearing caps face the fire wall, so yes, the arrow on the head matches the arrows on the bearing caps.
Very detailed video thank you
Our pleasure Joe. More good stuff coming.
Timmy I need your help. I had a bolt strip the other day while I was cracking the bolts off the bearing caps. I have tried two different bolt extractors, the first being a hammer in, which took forever to hit in, then I had to file a metal flange off the head of the extractor to get a socket on, which when it got on immediately just turned out of the hole. The second of which a twist on, snapped In the hole, which unfortunately means I now have a hardened bit preventing me from drilling the bolt out. I tried hammering on a 3/8 socket, and as a last resort vice grips. After the bolt extractor snapped in the hole I tried redrilling the hole with bigger titanium drill bits, then when that didn't work I tried starting small to incrementally increase the hole size. I then tried that all again except with hardened cobalt bits instead of titanium. I am running out of ideas, all I can think of is cutting off the head of the bolt with a cut off disk. I am not stoked with that idea. Thanks so much if you spent the time to read this.
I'm not an expert at extracting bolts and I'm not 100% sure from your description where you're currently at with trying to get the bolt out. Send me a pic: tim@timmythetoolman.com
@@TimmyTheToolman I got it out with a tungsten carbide bur! Thanks so much. it's crazy that the hardest part of home mechanic work is stuck bolts 😂
@@thaeloproctor I'm glad you got it out. Good job!
Hey i still have to use a valve cover bolt on the driver side exhaust cam to hold the gears right? Like you showed on the passenger
Yes, you have to use a service bolt to hold the main gear and sub gear together on the exhaust cam.
Hey, my 1996 toyota tacoma didn't have an electrical connector behind the power steering pump. Is that normal?
Different years had different pumps. Yours is probably the vacuum actuated one.
@@TimmyTheToolman thanks!
Hey timmy, why did we remove the crankshaft timing gear back in part 2?
We didn't really need to remove it per se. You would remove it if you wanted to replace the crankshaft seal. But, we removed it so facilitate cleaning in that area.
@@TimmyTheToolman great thanks for the tip
@@djrodriguez6582 No problem.
Great video !!!! Thank you!
Thanks and you're very welcome!
Hey I've been cleaning my block surface and I've been doin it for a few hours I used scotch brite and a razor there is still some black residue from the old head gasket there is no raised portions it feels really smooth amd the razor doesn't get hung up it feels smooth do u think I'll be ok to put the heads on with a little black still on the block?
A little black residue should be OK. We didn't get the block surface perfectly clean either.
Thank you very much
You're very welcome.
If I get this far do u think I could take the block out too would the top bell housing bolts be easy to get to with the heads off?
If got rebuilt heads with high mileage bottom end can I use high mileage oil still?
I imagine the upper bell housing bolts would be easier to get to with the heads off.
Tim, to quick zip nuts and bolts, what kinda ratchet? 😂
I have two Milwaukee ratchets. One is a more basic model, shorter and with less power, and the other one is a long reach model with more power. I love them and use them both all the time.

My heater valve broke while taking the hose off
Mistakes can happen, it sucks but that the reality of the beast. Learn from your mistakes and pick up where you left off. We made plenty of mistakes not always shown on camera so don’t beat yourself up over it.
- Sean
In addition to what Sean said, these heater control valves get very brittle over time. It's a good thing it broke while doing this job rather than somewhere much less convenient. I would say this was a lucky occurrence.
6:30 he says 10 mm bolt. Mine was 12mm idk if it's just my engine or you mispoke! Anyway if anyone else is like me don't bother trying for 10 minutes! Just check a larger size😂😂😂
Sometimes, I do say the wrong thing.
@@TimmyTheToolmanrarely enough that I trusted it for 10 minutes! 😂 No doubt your videos have saved me significantly more than that! Thanks a bunch!
Is that a duck in a rubber truck?
You are 100% correct Hayden.
