ROOKIES, You can do this! I am someone who if you pointed at something under the hood of my '04 Tacoma I couldn't tell you what it was before the project. There were some hardships, for instance, making sure you put the ignition coils back on the diagram correctly. My truck was misfiring when everything was finished because I rushed and put the coils on wrong. All in all, took me a total of 12 ish hours of labor and I got this done with my family. I learned a lot about my vehicle and am happy I did this instead of taking it into the dealer saving over $300. Engineered Mojo thank you so much for this video. Keep making other people's day!

[@EngineeredMojo]

Glad money was saved!! Every dollar saved can be allocated elsewhere. Just need the time and patience to get the fix done. Glad the install went relatively smooth and appreciate the time you took to share your story 😀

[@DocFortyThree]

Thanks for the confidence booster!!! I'll definitely try this myself. I'm being charged anywhere between $600 and $1000 for this, ugh.

[@hollowgr0und]

how much did total parts cost?

[@BigBoyz33]

I hate these valve covers so much, i did all the gaskets and cam caps/half moons and new washers all oem from Toyota and at the end of the day it still leaked 😂 gonna see what i did wrong here, thanks for the vid man

[@EngineeredMojo]

You're not alone! First-time I attempted this fix I had a leak. My valve cover torque was too high ironically and warped the compression of the seal

Thank you for the tips, I just finished the passenger side and put it back together and will do the other side another weekend. I like your pleasant voice. I watched this and others a couple times. I only did one the easy side first and didn’t even remove throttle body. Putting the little doughnut rubber things in freezer for a few hours and the pvc grommet and they went in pretty easy.

[@EngineeredMojo]

Freezer technique is a great tip, I plan to use that in future for other seals!

[@eljefeslash]

Well done, and thanks for taking time to film this. Very nice touch showing that screen shot of the part #'s and torque specs in the beginning. I had this done at a Toyota shop 2-3 years back, but I'm enjoying watching videos of it now so I can do it myself next time (hopefully that will be a while, but we all know it's only a matter of time on this one). Like you, I plan to drive this truck for a very long time!

[@philipperichen2702]

This video was 100% on track. Perfect details and to the point. Made the job super easy to follow along. I did have one problem that came up and I may not be the only person to experience this. As my truck is just about to hit 350,000 miles, when I was disconnecting the connectors for the fuel injectors, on every single on of them, the retaining tab to keep them locked in broke off. Touching them was just enough to do it! Looks like the mechanic who cleaned my fuel injectors may have experience this also. There was some gray material he placed into the connector to keep them together. Maybe some sort of silicone caulk? So now I don't want to leave these to chance covered by the plenum to come loose. Any suggestions? I hate to think of having to crimp new connectors on. But I can't just leave them like this to possibly fail.

[@EngineeredMojo]

Thanks for the solid video feedback :) Very common issue!! Haha, I actually ran across this on my older Honda recently. I ended up just buying a new injector connector i.e. the plastic head connector. Honda (and Toyota) have a special depinning tool to pop each wire out the back of the connector. No splicing is needed, but it is a delicate process if you haven't done it before. If you'd rather not do that, I've seen others ziptie or electrical tape around the connection after in place. They had no complaints at all

[@kevinw.8946]

Thanks man!!

[@EngineeredMojo]

No problem 😊

[@TheK9COPPER]

Paint-can opener tool works great at removing those spark plug tube seals.

I’ve got to clean my garage out in the front of my truck so I’ll have room to work. But I’m gonna do this gasket change. The left side is leaking quite a bit. Iv got another truck that I can drive if I need parts or something. Also I’m gonna charge the timing belt but maybe a little later. This summer.

[@EngineeredMojo]

Sounds like a solid plan, and it's helpful to have a backup vehicle when doing this fix. Good luck on the install! Not bad at all to diy

[@neilnarciso4945]

Thanks for all of the very helpful videos including this one. How do you remove the front camshaft plugs, which are sandwiched between the camshaft and the timing belt backing plate? Do you need to unbolt all of the semi-circular holders securing the camshaft?

[@EngineeredMojo]

Glad the videos have been helpful! For the front camshaft seal, you do need to remove the front sprockets and timing belt backing plate. After that there is a special tool you can purchase that will have a small lip that fits underneath cam seal and will pull it out without having to unbolt all of the caps or remove camshafts. If you google camshaft seal removal tool, I believe the company is YSL that makes a tool. Should be a few other companies as well, hope that helps!

[@neilnarciso4945]

Thank you, Sir! Again, very helpful information.

[@EngineeredMojo]

Thanks for the feedback!! Yes, same process for the other side as well

[@windowlizard]

👏incredible video brother! think any of the half moons or camshaft caps could be reusable?

[@EngineeredMojo]

Appreciate the feedback in the video! Honestly, I'm not sure. If in a pinch for money, I probably would personally risk reusing the half moons and caps given their under light install torque to begin with anywayd. However, I'd be nervous about having to do job over lol. Not sure if my nerves could take it

[@bogdanaronov351]

Here with a 04 tacoma with 334k miles hopefully i can get her to 500k and trade in for a new one

[@EngineeredMojo]

You have me beat by about 30k miles! Treat Tacomas well, they'll hit 500k on a regular. Good luck on the journey, I'm thinking similar. Hopefully, Toyota will have a solid EV truck option for me by then LOL

[@philipperichen2702]

Well I am about to undertake this project and this was a very concise yet super helpful walk through. 1 question. I had the timing belt done by a mechanic 1 year ago so they Hopefully did the right thing and replaced the front cam seal. Because it is not part of this procedure I assume it will not cause a new leak since the front cam seal should of been properly seated the the sealant applied and torqued down properly or would you not risk it and take the extra step to also do the front seal?

[@EngineeredMojo]

I personally do not change the front cam seals unless I have a current issue or visually seals appear damaged. The chance of a leak is rare enough there that I take the risk not to go through that extra work. However, I don't blame those who do for any extra peace in mind they want

[@ddemier]

Very good illustration on how to perform a valve cover job with half moons and cam cover seals on a 3.4 ltr. Is there a good aftermarket gasket kit to get? Any aftermarket seals available that you recommend? I see you listed OEM part numbers.

[@EngineeredMojo]

I don't have any personal experience with aftermarket valve cover seals, but given the valve cover is under minimal torque force I wouldn't hesitate to buy aftermarket from a reputable vendor.

[@derekmoore1387]

I broke a bolt on the coil pack when reassembling: it is recommended at 69 inch-lbs. Hopefully, this spares someone a little frustration.

[@sportytoes]

Was just taking a look at this after a repair shop gave me a $550 estimate to replace a slightly leaky seal. I was expecting a cover and a few bolts and done. Stupid intake manifold… still, $550, even if it takes all day this is more than i would make at work in a day. I think the key is having all the needed replacement gaskets for everything before starting. Once you start that truck is going nowhere until you finish.

[@EngineeredMojo]

That's true, having all the pieces and tools ready or at least having an uber account since they'll deliver tools from Walmart haha. But if you have the time and patience this job isn't too bad and it'll save you serious money.

[@Z-Ack]

Does removing the valve covers expose the water outlet? Like in the middle of the block.. cus ive heard that gasket goes sonetimes and have the gasket but only will replace it if i can do it without taking more crap off the motor to get to it,. Jusy did the timing belt so kinda at my limit on tinker time with this thing for a while…

However I’m having a hell of a time getting my spark plug tube grommets out. I’m assuming the job had never been done before, cuz everything is super hardened and gnarly.

What are the cam plug bolts torque

These do tend to come loose over time I have seen many be finger tight causing the leak after a year or two. I suggest adding a dab of medium strength loctite and not over tightening them like said but the loctite will keep them from backing off

They've been holding up well so far. No leaks. I do know sometimes there are manufacturer updates to parts overtime as common failures are realized e.g. axle seal was different from original to when I purchased on recently.

I have a question! I change my gasket cover and i have a misfire in cylinder 3 P0303 I didn’t have this issue before changing the gasket , anytip ?

[@EngineeredMojo]

Could have a bad seal around the spark plug tube seal that is leaking onto spark plug. For spark plug issues, I always swap plugs between cylinders to see if the issue switches cylinders. If it does then I know it's probably a spark plug issue. If not then it may be an issue internal to the cylinder

[@jdell2357]

Check your connection to the fuel injector. Possibly bent a prong and isn’t making continuous contact

[@riflebear1711]

Also check continuity between each injectors prongs. This is how I diagnosed a bad injector.

[@riflebear1711]

You said reinstall the spark plugs... do these need to come out? Or did you mean spark plug wires?

[@EngineeredMojo]

Oh yes, I meant spark plug wires. However, since you're in there already, it may be good to swap and put new plugs as well

[@rafaelgonzalez4935]

Ya se por que no se puede pasar uno de torque la tapa se parte hoy me paso parti una de mis covers

[@EngineeredMojo]

Si, los tornillos son senstivos!!

[@jeramemedina4088]

Did you have to take the spark plugs out?

[@EngineeredMojo]

I didn't, but if you haven't changed them recently, it's a good time to swap them out for sure

[@levimeyer6944]

As someone who is in need to do this but is an absolute rookie with vehicle maintenance. Can this be done in one day?

[@EngineeredMojo]

Yes most definitely, I'd just plan for a full day so you can take your time with the removal of items

[@levimeyer6944]

I just got off the first valve! Do I need to disassemble the camshaft bearing or can I leave it?

[@EngineeredMojo]

@Levi Meyer you can leave the camshafts as they are unless you plan to install a new camshaft sprocket seal. I didn't perform that for my install, but some do perform that install at the same time. Hope that helps!

[@imahitu]

Im a little confused. I only saw one gasket removed when you took off the lower part of the plenum @6:15. But you said there was 2?

[@imahitu]

Is it just the one shown at 6:15 and the one from the upper section?

[@EngineeredMojo]

@imahitu there are two gaskets, in the video I am showing you just the one cylinder side. This is a v6 engine, so there are two cylinder heads. Hope that clears it up for you!

[@joseroldan2924]

what is the bolt tightening pattern ?

[@EngineeredMojo]

In general start in the center and cris cross /alternate your way to the outside for tightening is what I follow

[@octaviozavala7198]

What is the part number for those half moons or how do I order them?

[@EngineeredMojo]

It's labeled as semi circular plug in the tool list in the video description. I irdered those from my local Toyota dealership. Hope that helps!

[@octaviozavala7198]

@@EngineeredMojo thanks 👍

[@BruceschultzAU]

How many hours does it take to complete full job ? Thanks in advance.

[@EngineeredMojo]

It took me about 4-5 hours and that included filming. I'd say a 2-4 hour job taking your time probably

[@BruceschultzAU]

@@EngineeredMojo thanks heaps for the fast reply I really appreciate it. Best video on topic on the net. Thanks again mate from down under.

How do you know

[@michaelstewart218]

What are you removing at the 6min.

[@EngineeredMojo]

There is a bracket with (1) 10mm bolt I believe holding in a coolant tube

[@dominicmartinez216]

Just curious… what was the cost for all of the OEM parts? I know the gaskets alone are $60 each at the dealer.

[@EngineeredMojo]

I bought an oem package off Amazon or ebay. I can't remember which, but I know in total all parts were under 200 total for gaskets

[@sbernardo8276]

The only thing you need to buy genuine Yota is the cam plugs.. fel-Pro blue gasket kit exceeds Yota

[@cobradwight1]

I spent like 200 for everything at the dealer .

[@jamesfarmer2748]

the fel pro plenum gaskets are paper and not as good as oem or Mahle in my opinion.@@sbernardo8276

[@riflebear1711]

Going to know. I've got the blue fel-pro kit on deck red to go!

[@jeremywscott9090]

Lol tube seals are installed upside down!💯how do i know this?because im a master toyota technician of 22 years.i see this all the time lol

[@EngineeredMojo]

Oh dang good to know the factory service manual install pictures are bogus!

[@riflebear1711]

Wait are you saying he installed the seals upside down? Or the old ones were installed upside down?

[@Rhecsh1t9845]

This was two years ago so you likely won’t reply to this comment in time but is it necessary to do the little half moon things?

[@EngineeredMojo]

@Rhecsh1t9845 not necessary but recommended since you’re already in there 😊

[@Rhecsh1t9845]

@@EngineeredMojo do they go bad or something? If they go bad what happens?

[@EngineeredMojo]

@@Rhecsh1t9845 it's more about once the valve cover is removed, the sealant may be compromised in some way

[@hollowgr0und]

How much did total parts cost?

[@EngineeredMojo]

I can't recall, but it was around 100 dollars USD or less

[@SethMason88]

Soooooo, how do you know?

[@EngineeredMojo]

I never know...

[@yesyismaelvlogs7344]

Whats 53in lbs in ft lbs ??

[@EngineeredMojo]

It says 53 lb-in. It's a measure of torque. Don't confuse it with lb-*ft* or you will drastically overtighten those bolts. You need a smaller torque wrench typically for lb-in values

[@riflebear1711]

53÷12=4.4. I believe that's how you convert.

[@Z-Ack]

You dont have to remove throttle body. I didnt because didnt have a gasket to replace the old one.. i got that far at least..

[@EngineeredMojo]

This is true, I only remove it so I can change the gasket. Wanted to get as much done while in there as I could haha

[@user-zn3hn5be1v]

Why didn't you spend 2 mins. and clean at least the inside of the valve cover, and also just for looks the outside of the valve cover? What looks to take at least 2 hrs use to take 10 mins. total for both sides in the days of carburatored engines. How sad. Great video though, just to show how involved it truly is.

[@EngineeredMojo]

I was exhausted haha and wasn't too worried about the inside given there was very little buildup, appreciate the video feedback!

[@sbernardo8276]

S Bernardo 58 seconds ago SMH.. You bought parts you didn't need .. Fel-Pro exceeds genuine Yota on valve cover gaskets and seals. Usually $35..you didn't need to remove the throttle body it will come off with the plenum ..the passenger side injector harness is not in the way..The drivers side is more complex.why on earth did you bend the tabs up in the inside of the valve covers that house the spark plug seals? You should watch more youtubes before you attempt one yourself! SMH!

[@EngineeredMojo]

Appreciate the video feedback and your opinions! If you have data to back up your claims on oem not being as good please share! Watch the video and you'll see why I removed the throttle body to replace the gasket.

[@sbernardo8276]

Well the throttle body gasket wasn't broke if you hadn't removed it then you didn't need to replace it. Years of experience tells me that Felpro silicone valve cover gaskets are superior to any OEM

[@EngineeredMojo]

@@sbernardo8276 that's awesome! Thanks for the tips and info. I'll use the ne t time I do this hopefully in 15 years haha
