HERE IS PART 2: • Here's Why You NEVER M...
Toyota's 2UZ-FE 4.7L V8 engine is one of their most reliable engines but it's now pretty old and therefore we're starting to see some issues pop up and even become 'common'.
In this video I'm focusing on the passenger side valve cover gaskets of my 2005 Toyota 4Runner Limited with the 4.7L V8. This truck has 236k miles on it and is in desperate need of some attention. The valve cover gaskets sound like an easy DIY job and it certainly can be. However, when you start tearing into an older engine, you're bound to find other issues (which is/can be a good thing). This engine is no different. Other than the severely leaking valve cover gaskets I found a few issues with the spark plugs being VERY loose and as a result, the ignition coils being covered in combustion soot. I also found a few smaller things like cracked vacuum hoses but those aren't really worth mentioning.
The issue with the loose spark plugs was so severe that at the last minute of editing this video I decided that content needed to be removed and made into its own video. So expect that soon.
I'm hoping that decision helped this video be more focused and to the point. (I'm also hoping you like it!)

As some one who is familiar with these engines…the valve cover gaskets are known to compress after initial installation and then later on requiring another torquing in order to get the gasket to make a proper seal again. That’s how it on my GS400 (1uz-fe) and my Tundra (2uz-fe).
The spark plugs on the other hand sound like they were not installed properly. There’s a crush washer on most spark plugs and it seems like whoever installed them did not actually crush those sealing washers. Leaving it not torqued correctly hence them loosening up over time. Hope this helps!
Yep even re-tighten them after 30 minutes is better than nothing
I concur. Common issue with the V8 and the V6 as well. My new to me 98 4Runner with the 3.5 exhibited the same condition with loose bolts. Some forums suggested a retorque vs gasket change but I did my due diligence and changed anyway…looks exactly the same as this in the video just minus 2 cylinders. I will say though my dyslexia got the better of me and I over torqued the first valve cover. These things don’t take much at all. I believe the specs on the V6 were like 10in/lb and I went and did 10ft/lb…big difference. Didn’t cause any problems but I did momentarily panic, cuss myself and went through a few other emotions before I threw caution into the wind.
@@C-ME3 There was never a 3.5 in a 4runner. The 5VZ-FE is a 3.4
@@user-vj1es1ce4u I’m aware. Pardon the typo.
@@C-ME3 Consider yourself pardoned. 😁
A single vehicle subscription to alldata for a little over $100 would do you a world of good working on this truck. Every torque spec, wire color, factory procedure etc.
I'll be looking into this for my old Mitsubishi. Thanks.
Here's why YOU NEVER MESS with you factory valve cover gaskets 👍
As an owner of a '01 Tundra with the 4.7 engine, I will definitely be looking forward to future 4Runner videos Jimmy 👍🏻
Awesome! Thank you! Lots more coming.
Mine on my 2004 Tacoma with 87k original miles were leaking. I couldn’t believe it was just the bolts were finger tightened. I snugged all the bolts up, the leaking stopped!!!
They should be torqued to 9 ft-lbs. It should be normal for the bolts to loosen after so many miles. That's why they feel loose. They just need to be retorqued until the next time you need to change gaskets. The valve cover is not a big deal. It's more of a beauty cover that helps keep the oil inside. It's the plenum underneath it that is more important. I'd rather the valve cover crack than the block underneath.
Honda and Toyota spark plug tube seals go in the opposite of the way most people think that they go in. Unfortunately, you put them in backwards. You can confirm what I’m saying by reviewing the orientation of the original seals at time mark 9:38
You can see it even better at the 7:31 mark.
RIP.
The lip faces the oil.
I agree. They are in backwards. The valve cover will be easier to install this way since the lip is facing up. But it’s wrong. The lip faces the pressure side.
i am happy to see that toyota went with metal half moons. the half moons on my 22re were rubber till i found some metal ones and swapped them out.
Great video 😊 I appreciate your work 😊
Trained or not, you do a great job! Love the content!
bolts were just as loose as yours. The older the rubber gaskets are, the more they shrink and this is what causes the bolts to seem like they came loose when indeed the bolts have not moved. I re-torqued my bolts a year later and they really did not need it. I also used a felpro kit and asdide from the plug tube seals being blue silicone, my gaskets were also blue silicon and this is possibly why they did not need a re-torque. My engine is the 3.4 V6. You did a great job!
You put the spark plug tube seals in upside down. The lip always goes towards the pressure side. That way when pressure is applied it pushes the lip seal out helping seal even tighter. Look at the before video and u will see it. It will be easier to install the valve cover this way but it’s wrong.
I have replaced many spark plugs tube seals on all kinds of different vehicles and they are always installed the way he did it. If you install them per the service manual he’s correct. I’ve only seen them installed the other way when someone doesn’t know what they’re doing
Great job, Sir! Enjoy your channel.
Bolts come lose from so many heat cycles of the engine. It's not that they were left that way. It's just a typical thing that happens. You did great though. Nice work Jimmy!! 💪🔥
The bolts weren’t tight because the gasket failed. Think about it: If the gasket completely disappeared then you would have to close the gap under the valve cover by tightening the bolts. While the gasket didn’t disappear, it did flatten and go hard so it wouldn’t compress under the valve cover and spring/push back. That makes the cover loose.
Looks like a good candidate for the Valvoline restore & protect. Should read about how it works.
Sweet! Just commented to someone else that I’m about to put that in it and run it on that for a while. Looks promising.
@@1RoadGarage how it works is you use it for 4 straight oil changes to get the result. Otherwise if it cleans to quickly it’ll clog your filter. UA-cam channel The Motor Oil Geek has a great video about it. Check it out.
Definitely go check that video. Good content if you’re not already aware and that stuff does seem to be legit.
Car care nut, is a you tuber who is the man when it comes to lexus toyota engine, unfortunately he said blue gasket is the wrong gasket and only original factory gasket should be used, I watched him do this job on a 3uzfe and the spark plug gasket looks totally different. I would use his knowledge on any toyota lexus project I was involved in. In short, he is the man.
LOL I will match my 52 years experience in automotive repair against his ANY DAY, although much of what he says does make sense, and he IS honest.
I dont always think factory parts are the best. A (very) few manufacturers are superior to factory parts. Standard Motor Products (Standard plus/Blue streak) is one of them.
Fel Pro gaskets were often used by the factory, I tore down a 1964 Ford 390 in the early 90s that had both Ford and Fel-Pro brand markings on the steel-shim type head gaskets..
Aisin water pumps and timing components are factory equipment in most Toyota vehicles, although Gates components ( Gates is the inventor of the automotive V-belt) is equal or superior to Aisin.
I would never speak against 52 years of experience when I have only oil changes and break jobs as my experience, I respect ccn for his experience and making quality videos I can follow and learn with. Wisdom should always be listened to and considered, now I have your opinion and his to hopefully make a good decision. Thank you!
@@buckandbrandy Youre welcome.
I started doing repairs in high school in 1972, and have done it ever since
Ive worked on everything from Chevy Vegas to Jensen Interceptors.
I did this “simple” task two years ago on mine at 250k miles. Whoever owned it before me, cross threaded those bolts on the driver side down near the brake fluid reservoir. They snapped right off and I had to get it towed to a mechanic to remove the entire engine head and have those shafts drilled out, retap the threads, and put it all back together again. Good thing my timing belt and water pump were due for servicing! Plus I had the alternator, starter, and powering steering pump all replaced while things were out.
Wow, that’s exactly what I’m trying to avoid! Thanks for sharing. 👍👍
Can't wait to see you do a video on changing the fuel filter on this car
When I was replacing a valve cover gasket that was last documented in 2012, so 12 years, the bolts holding the valve cover were impressively loose similar to yours. Makes sense why oil loss was at an all time high for that Camry.
My very 1st timing belt and water pump job was on my 4.7L.
I went ahead and did the valve cover gaskets at the same time.
The driver's side gasket is a real p.i.t.a. btw 😁.
Oh and I think your wife is going to 100% fall in love with that vehicle.
I’ve already done and filmed the driver side and it was NOT FUN! Broken bolt!! It’s all in the next video.
Yep you Ut the plug tube seals in backwards
I own an old Mitsubishi and not a Toyota/Lexus, but I find the issues and component placements are close enough that I can recognize and apply what I see in your videos.
Both me and my buddies 4.7 had loose bolts on valve cover. Known issue, I guess.
I had a 85 corolla with the 4 cylinder and I had to replace the valve cover gasket on back in the 90's and it was really easy.
I have a 01 Sequioa i just purchased and the bolts were the same...only ones tightened were the 2 towards the firewall. Unfortunately both sides had 2 bolts break off. (Closest to firewall)
have you ever tried amsoil products? i use it on the several fords i have owned over the years and have had very good results from it. they also have a engine flush that i think works well. its on the expensive side but its well worth the money for keeping the engine clean and better gas mileage.
Never used it. I hear good things. I just picked up some Valvoline Restore and Protect and gonna run that for a while. Look it up. Seems like good stuff.
Jimmy,Go Purchase 2 bottles of STP Pro Intake Valve Cleaner.
Excellent Stuff!!!!
I gotta do this on my Gs400.....not looking forward to it, but I gotta change the spark plugs anyways.
Looks like a good anti corrosion feature. I'd top up the oil and leave it. 😅
FYI you put those lip seals around the spark plug tubes backwards.
At least your able to work on your Toyota. I'm having issues with my upstream O2 sensor. It take a wideband air fuel ratio O2 sensor. All Toyota's do. I wasted money on the wrong O2 sensors they were narrowband. Next is the hook up the pattern they use is different now days. I'm worried I won't beable to get the right sensor for the Camry because of this age of the Camry. Enjoy your journey with the Toyota you now have.
Sorry to hear about that. Thank you for the encouragement! 👍
When will you replace the spark plugs on the 4Runner? 😊
Conversion from inch pounds to foot pounds is 12 to 1
This owner really ran the car hard. Im sure i have seen examples that are in way better condition for a little more.
I have a 2tr-fe. It was flawless u til it wasn't. I also live in the Canadian rust belt. 215k on it. Now the head gasket went. I'm getting it done. 6k canadian.
literally installs a spark plug seal in upside down
He definitely installed it the right way
If they are leaking like your's it's probably a good thing as far as changing VC gaskets as it appears your lower cap screws are well lubricated and may come out without breaking. I did mine because I wanted to paint the covers as they were corroded and ugly ... broke 3 cap screws and I soaked them everyday for a week before with liquid wrench. Not fun then!
you should add some sea foam high mileage to the oil before you change it, to get rid of some varnish in it! drive 300 miles before changing it!
You did the entire job correctly. But instead of using felpro. You should have used mahle . Not sure if I spilled that correctly but yeah those are factory
Toyota experts in the comments , like clock work 😂
Toyota Valve cover bolts are supposed to be torqued up to 90 in-lbs. Newer valve covers are made of plastic. The engineers figured it would be better to sacrifice the valve cover and let the leaks happen instead of a catastrophic failure in the more critical areas. Just retorque to 90 in-lbs till it stops leaking. The valve cover is not a big deal. It's more of a beauty cover that helps keep the oil inside. It's the plenum underneath it that is more important. I'd rather the valve cover crack than the block underneath. Spark plugs should be between 12 to 14 ft-lbs. Mine are at 13 ft-lbs. For me 13 ft-lbs felt too much for aluminum.
Idk bro I would say personally the 2JZ is their most reliable engine ever made by Toyota that were in the Lexus GS300 SC300 and Supra exc and the UZ v8 is a close second but as of now the 2.5l i4 in the current Camry is being voted in as the most reliable motor ever made worldwide so we’ll see
Those bolts are like 18 ftlb torque. Almost a little bit over hand tight. Over time and with compressed gasket they will loosen up a bit
I took my car to a Toyota dealership to fix a small oil leak and they tight one bolt and let the other three half way in. The undercover cove of the car was missing bolt, so I took it back and told them to tight the bolt they let lose and install the undercover bolt.
Yes the spark plugs are 13 ft lb torque and the valve covers are 7 ft lb torque for the 4.7 Toyota V8 engine
oh not inline 4 its not the one i think of being a 500k car and all valve cover gaskets suck on v8s and wait until you find out where the starter is on some of toyotas v8s there behind the exhaust manifold not this model year (i think it was a 2014ish) but its a lovely job that calls for 10 hours and can be done in 5 if it all goes well.
Just did my spark plugs 2006 tundra v8 . They were all loose
Really?? Was there combustion soot on the ignition coils like mine? When’s the last time you checked/changed them?
53 in-lbs is the correct torque value for the valve cover bolts.
The OEM gaskets are cheaper in price than the aftermarket and better quality. Always check with Toyota parts online and pickup at a close dealership!
My guess is that the valve cover bolts were that lose because the gaskets are that dried up and shrunk.
Same here. I mentioned that in the video. 👍
@@1RoadGarage Yes I caught that later on. I been subscribed to your channel for awhile and get some good ideas from you, thanks.
13:27😆
Valve cover gasket s are only as good as the material that is used to make them
Just a guess and I'm no mechanic but maybe the bolts just loosened over time
I read or seen somewhere it's said they're supposed to be not too loose but not too tight. They were loose on a sienna I had as well but I tighten them all the way down to stop the leak 🤷🏽♂️
Torque specifications make a world of difference
236k you should worry about the timing belt..
Toyotas best engine was the 22RE.
Steam clean the engine compartment and it will be spick and span
Stay away from Felpro. We utilize Mahle or factory OE. All that work to only use cheap materials.
sounds like bro here is going to end up getting a welder and learning to booger weld.
I went to welding school for 3 years and learned every discipline of welding. Started with Oxy acetylene then stick then mig and ended with TIG. Super fun and rewarding.
@@1RoadGarage Sounds like you have the know how and tools to weld on a nut and get this bad boy out.
Change the timing belt and after 500 miles retorque the valve cover gaskets
You may have noticed only one sticker for the timing belt but it has indeed been changed just 30k miles ago.
@1RoadGarage awesome. Sorry i didnt see the sticker. Thats great
Don’t forget to replace the VVT filters it’s very very important parts to replace in Toyota engines
You look like Burt from Tremors
Stop crying, what do you expect after 200,000 miles.
