- 100K Subs!? HOW? you guys are AWESOME!
Want to see a particular engine torn down? I may have already done one! I've made over 60 other teardowns from Cummins to an LS7, and from Rotary to Ram Ecodiesels. Check them out here • Blown Up Engine Tear D...
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. If you're interested in buying parts from this engine or the other engines I've torn down, email us at Importapartsales@gmail.com.
In this video I completely tear down a 4.7L 2UZFE engine from a 2005-2006 Toyota Tundra. This is the variable valve timing variant found in 2005+ Tundra, Sequoia, 4Runner, Land Cruiser, Lexus LX470 and GX470. These are some of my FAVORITE engines Toyota ever made. Unfortunately whoever owned this one neglected to change the timing belt resulting in timing belt failure. While it was apparent that some maintenance was done on this engine, the timing belt wasn't. Also, whoever dismantled this engine and left it outside made it a lot less repairable. All in all, this engine was discarded for no real reason but the damage done left it better used as a parts engine.
I hope you've enjoyed this teardown! As always I love all of the comments, feedback and even the criticism.
Catch you on the next one!

So let me get this straight. What did the most damage wasn’t the timing belt breaking, it was a knucklehead leaving outside after he took it out of the truck?
Yep I was just thinking the same thing
@@jedidiahkuepfer8889 what a shame.
I don't think the motor was hurt by the broken belt. Could have stuck a new one in and tried it before they ripped the motor out.
What amazes me about "leaving them outside" is that a plastic bag would be enough to keep water, out only a few cents even at "engine sized" and preserves the value even if it's "just a core"
Man a 3 hr job and this truck would’ve been back on the road. I should do mine soon, sitting at 140k last done at 80k
You're absolutely right---any decent mechanic would've performed a leak-down test to check for bent valves, as well as used a boroscope to check for piston damage. This engine could've been put back on the road with nothing more than a new timing belt
That's the biggest tragedy with this engine
dumbass mechanic probably put some high mile oil burning pos back in the truck.
I'm surprised no one tried just putting in a new belt. My brother's civic's belt snapped and we put a new one in and it was fine!
Honestly. My 97 4runner was parked for 3 years since the PO has a coolant flush botched by the local repair shop, which blew both head gaskets, filled the cylinders and oil with coolant, and torched a head. Somehow the belt also shredded in the process. .030 off the heads, a quick hone (without even removing the pistons), gaskets and a belt, and it fired up like it was parked a day ago. 90s/early 2000s Toyota’s are like cockroaches, you just can’t kill them.
Probably just as expensive swapping motors than putting a timing belt on it. But you know the social media experts that have never turned a wrench would disagree.
I agree completely, what a waste of a perfectly good engine! A bit of negligence can go a long way as we see here. Great video buddy. As always. Be well. Big Al.
Yeah but who know it could have been in a rusted out pile that wasn’t worth puting in over $1000 for preventative maintenance
that engine is an example of all toyota owners. they last forever..
@@harrywalker5836 I agree with you, my FJ Cruiser is twelve years old and runs like new.
Best V-8 engine known to man when maintained!
Don’t let Scotty see this he might have a heart attack
The 4.7 is the best V8 as far as durability wise that I’ve seen in my 30 year career as a technician. As long as a new belt, pump, and oil changes are done as needed the owner will wear out and die before the engine will. I have serviced several with over 400K that still purr like kittens. One million miles is certainly doable with one that’s cared for properly.
there are a couple 1 mill tundra.
Agreed . What's so sad is the tech or buddy removed the engine . I suspect it was a weekend buddy job .
You must have been a Ford tech cookie cutter you never seen a real durable engine In your life Son I have built 318 Dodges that will out run out last out do a toy yotie piece of shit
Good news! My 2001 Tundra with this engine and less that 100k should do well for my grandkids.
I have a 2000 tundra coming up on 250k and can agree with this. That truck will not stop.
Still have my 05 tundra.768,000 kms and 5 belts later,still runs like the day I bought it. I’ll put another 700,000 kms on it then I might think about getting a new truck!! Or maybe not.
Cheers to all. 🇨🇦🥃
😳
768,000 km?? Seriously..do you ever work or do you just drive around 24/7😁 I cannot fathom being on the road that much!
By the time this engine wears out on you, it might be the case that the only thing for sale is electric vehicles!
at another 700,000 kms that truck might be getting a new owner aka your kids bc that truck very well might outlive you hahaha. Must be a hell of a club being an engine that outlives its operators lol.
@@44R0Ndin doubtful, it has occured to me that electric vehicles simply cannot penetrate the lower end markets simply because you cannot install chargers on an apartment since you don't own it and nobody has time to wait an hour for a supercharger elsewhere to get you up to speed. At the very worst we will see mostly hybrids, but all electric remains hardlocked to the middle-upper classes who own properties and can afford to mod them to support EV's.
My friend has a 2004 Tacoma V6 with 305k miles... Still on the ORIGINAL timing belt! Non interference engine so he's not worried about it 😎😉
My 2006 tundra has 352,000 miles. Still runs strong. There are at least 2 4.7s that have gone 1M miles not rebuilt. Those spindly rods are why this is not a great engine for lots of boost. Great video again. Thx
This channel has taught me so much about engines, how they are designed, what different components are and how they fail. Really appreciate the hard work man!
After you take your last breath are you going to heaven or hell? Please ask yourself that question.
Jesus can save your soul from hell. He will forgive your sins. He said whoever calls upon his name shall be saved. Call upon Jesus today. Repent and believe the gospel.
And 100% hunk of junk designed to fail and gasket leak all the way to the repair shop for the life of the product no matter what manufacturer or country...I am so glad the ice engine is dying...such a stupid 🙄 technology...never changed, never innovated for 100 years...throw all the hunks of junk in the shredder I say...
Why believe in a made up story?
Lmao, junkyard BS
That is why i like timing chain engines vs timing belts.
Chains don't last forever either though. The Achilles heel of most German engines is timing chain/guide failure
Yea belts get old vs a chain that seems to last forever as its usually coated with oil.
@@repairvehicle Chains are better it has nothing to do with brand loyalty. New Toyotas have a chain at least that’s what I’m told. They say a chain nowadays will last as long as the rings. Tensioners and guides are a hole different argument. But you shouldn’t be loyal to any auto manufacturer they will all screw you over.
@Jeff Bigsley , Toyota chains last forever if
maintained
I had a Pontiac sunbird with a 2l with 68k on it and on cold start a piece of the tensioner broke off and went for a ride. Snapped the end of the cam off and was so bent it never came out. My second car was a Volkswagen and put 875 k on it and it was a belt that I replaced 7 times. Was parked and someone texting and driving finally finished the car off.
I remember hearing non-stop that people claimed the 2uzfe was interference.... Well the belt broke, water pump seized up and melted the belt to it when it was stopped, then it was cranked over and snapped the belt. cranked a bunch and it wouldn't start. After tearing it apart and seeing the damage, there was no problem with the internals... no damage to the valves, still runs perfectly 100k miles and another belt change later.
This is why I'm not of fan of any engine that uses a timing belt unless its a non-interference design. Yes, I know timing chains and gears can and do go bad and can cause even more damage but the odds are in favor of metal over rubber.
I have a 2007 Sequoia with this engine, it’s a maintenance service about every 100k....I don’t consume oil with 190k and the oil is never burnt at 5k oil change. This is the most smooth and reliable engine I’ve known. My company Tundra has 420k on this same engine and only have done $2000 worth of maintenance on it. They are legendary, it does have the belt as a minus but it’s worth it.
I agree man, although it's not a vvt engine, I still drive my 96 Toyota 5sfe 2.2 and it uses a timing belt. I replace the belt every time I have had to access anything beneath the timing cover. (oil/water pump). Great little engine and the reason why I have strong faith in it is due to the fact it is non-interference.
Nothing bad with timing belt when you maintain it like you should
@@miteshshah8060 yeah and my 4.9L Ford I6 is 350K old without any oil burning issues and is on 5k oil change intervals as well. But it doesn't have a timing belt. Or even a chain. Just two steel gears lubricated with a direct oil spray.
Even on a non-interference engine, a timing belt is a dealbreaker for me. I won't buy one. It's a lot of expensive maintenance that just does not need to be required at all.
Testimony , 280 k miles 02 Sequoia . Belt broke , replaced timing belt and components - runs like new again . Just do it guys , this 4.7 is bulletproof . Also , starter replacement is tedious but not impossible .
I do my belts every 95K, approaching 300K and it is just such an amazing engine.
9:06 did you see the screw that fell inside the engine when pulling the intake manifold off?🤔
I saw that too. I was gonna comment if no one else did
Another great Saturday night video. Being remote full time for work, I think this channel resets my equilibrium when it comes to what day it is.
I enjoy this channel a lot, keep up the great work. I'm a Toyota tech for over 17 years, I wonder how long that engine sit around. Other than the rust in the cylinders I think a timing belt would had put this engine back on the road.
Our 04 Tundra has 301K and our Lexus 470 has 198k which still drops clean oil every oil change. Timing belts are changed every 90k. So I agree 100 percent take care of what you have and you should be a much happier owner. Thanks for sharing!
I have 2007 gx470 has 150,000 mi . Do you recommend changing timing belt and water pump. Everything running perfectly. Idle perfectly too or wait until it hit 200,000. What your opinion?
@@skeletronxxprime6277 yes we change both every 90k as Toyota recommends. It’s a belt and not a chain so they can be subjected to breaking more so. If they do you are more then likely going to have valve train damage. Enjoy your GX we love ours.
Such a shame! Neglect tore up such a great engine. Somebody probably could have put a belt on the engine (before it was left in the rain) and it would have run fine. Hopefully you can sell some parts so another Toyota one can stay on the road.
Probably would've ran fine for a while after the rain too. Little bit of blow by, but better than a scrap car!
Why are timing belts even used, chains are far superior and less prone to rotting to the point they snap
I can confirm the 5.7L tundra motor has a much worse location.
Right behind the passenger exhaust manifold is impeccable placement! Adding to my annoyance were the rusted out nuts/bolts that broke off the manifold when removing the exhaust.
Thankfully an acetylene torch was able to help me remove the broken old studs.
You are right about the starters on this motor. I've sold car parts for 14 years and have never sold a starter for a Toyota 4.7.
Mine went around 130,000
This and Northstars, even if they do fail, pulling intakes on these vehicles isn't as hard as getting the exhaust out of the way on a lot of other vehicles.
They saw the broken timing belt, then probably looked it up online and found out it's an interference engine then they threw it away. Interesting how the valves escaped unharmed. Looks like there is 3.rd term for this engine: mostly interference, but not always .
This happened to my 2004 tundra, I put a new belt (and waterpump /timing stuff). Has been running for 2 years since that day and no issues. No valve damage and compression/leakdown were good for a 300,000 mile motor
Don't ever worry about "shameless" plugs - if it keeps bringing us videos like this. Another great job. Already cant wait for next week.....
One of the best engines Toyota built. Had one in my 2000 Tundra. I ran great. Yes I did change the timing belt. Had it changed twice in the 14 years I had the truck.
I had a 2000 Tundra. It had 260k when I sold it and the guy drove it for another few years
You know you engines! Yes, my air pump went out on my 2007 Tundra with this 4.7 but Toyota covered it. Funny, I needed to inform the dealer that is was covered after they quoted me over $2000.00 and a little research on my part. Anyway, the time belt is also a big job on this engine since the radiator has to be pulled and it's a tight squeeze pulling the water pump.
So either the belt went and the mechanics talked them into just replacing the engine. Or, the belt broke, engine quit and the driver panicked and had an accident from loss of steering or brake power and the vehicle was wrote off. Either way. Clean that up and a new belt. You have a perfectly good engine.
Idk man, that rust might be an issue that isn’t worth fighting. Might as well get another bottom end to slap together with those heads.
Change the belt in my 4.7 after 17 years. Had less than 90K miles but was 10 years overdue. Still looked new when I changed it.
Love the channel man, love the teardowns and love the analysis. I also really like your penchant for BMWs! One suggestion if I can - the father and son that made you the aluminum hammer - it'd be awesome if you left like a handle like an instagram or something. They put work into it and not even calling them out by name is something that you should definitely rectify next video :)
Sh sh sh sh shut up
It’s fine.
Have you ever seen anybody work as fast as him? I sure havent😂
Mine has 222K mi. Still running strong. No oil leaks.
If Furd had anything to do with that engine it wouldn’t have survived long enough for the belt to break.
Fords do not break timing belts because they use timing chains that do not break.
In memory of my old 1UZ-FE, the old Toyota UZ engine are non interference engine, so valve and piston will not have a chance of contact in any circumstances.
About to change mine, I believe it still has the original belt (220,000 mile)
I have a 3.0 d4d Toyota dyna 4wd and the belt can snap on these engines and the valves won’t get damaged, I still get my belts done on time. Regular oil changes are also needed fuel filters air filters max sensor cleaning. And your good to go
Seriously enjoy all your videos and the narrative/commentary! Best “Dad joke” so far: “…probably my biggest fan!” Keep the great stuff coming and thank you!
I agree I hope he does something for high school students that take auto mechanic vocational classes.
Just did my timing belt and some other maintenance last week! Belt was in decent condition but still wanted to avoid this
The engine looks like it could easily be put back together with a new timing-belt & run perfectly.
even though the tundra is an "interference" motor , I have seen several that broke a timing belt and did not bend valves , fact is I never saw one bend valves
Spoken like a true craigslist clown. Ran when parked, just needs carb cleaning.
Fantastic video / 'tutorial'!!. (I'd wish I could've subbed 10X). Great info / remarks. All respect to Ben Iacobucci's comment: I'd dare add 'most Toyota engines, even those from 1.963', (My own / late Grandad's FJ40, very same one I used to 'learn' to drive @ one of his farms, early 1.980's, when I was about 10 yrs old), NEVER die, unless some jerk does 'something really wrong on purpose'. I still keep my late Dad's 1.984 Nissan Patrol / K160 w/ original P40 petrol engine purring like a kitty. Why anyone?.. Quite simple indeed. It's almost my Family's tradition 'cuz Toyota & (most) Nissan's reliability, as long as you perform due maintenance BEFORE deadelines. I even have motor's oil / tranny's fluids changed at least twice a year, keeping in mind oils / fluids tend to oxidize, even if the motor / vehicle is used less than 200 miles per year, as my old Nissan Patrol or 1.995 Toyota Land Cruiser FZJ. BTW: I'm NO mechanic / technician, (I'd wish I were one!). I'm just an ER/ ICU Dr.
Total waste of an expensive wiring harness. And why do these guys leave perfectly good engines out in the elements? Near where I live is a disused train maintenance facility turned into a dismantler. Majority of the vehicles are under one roof and on concrete. I appreciate not all can be so lucky, but what a great way to preserve cars and parts and it's self-serve, so we don't need to slog around in the searing summer sun, mud and rain ;-)
Your right !a stupid plastic tarp could have saved a perfectly viable engine .
I had a 2001 tundra with 4.7 I went 230,000 never changed the timing belt or do anything to the motor. Best damn truck ever
anyone catch the bolt falling into the intake port when the intake was removed?
If an 20 overbore would correct the issues, there is a .020 oversize piston and ring kit for this motor on Rock Auto for $41.79 each, multiplied by 8 is $334.32. Machine work on the cylinders maybe $500. A complete gasket set for a rebuilt also on Rock Auto is $104.79. The bearings and crank looked practically new, I personally speaking would re-use them. Timing sets that include new water pumps and seals run from $127-$232. I'd probably have a valve job done and the valves cleaned up at the machine shop also. Total cost $1500 ish
Had one of these 2UZ-FE in my 01 tundra, 385K miles start stop 10-20 times a day (service truck) original starter ..
Same amount of miles on my 1uz, but I'm in 2nd starter.
I own an 06 Tundra with this very engine. I love that truck.
As an owner of a 2002 Tundra with the 4.7L, I am astounded with the smoothness and reliability of this engine--even after 235,000 miles. I've owned other V8's and, so far, nothing has come close to the build quality of 2UZ. You're teardown proves that.
😂 plenty of v8s are smooth at 300k
@@ChrisB-cx6td oh yea? What v8 do u got that has 300k miles on it everything original but spark plugs that DOESNT burn a drop of oil either? Fool.
I miss my 01. I panicked and sold it at 75,000 miles because of fuel prices.
I'd rather pay an extra 100$ or 200 a month in gas than spending 60k on a new truck. No thanks
@@Jeff-sp7bgthat's exactly why I still have my 04 tundra. It only has 138,000 miles on it and it's paid for. I looked at a new Toyota pickup the other day, $51,000. I'll keep mine.
Best way to find if a bearing is bad to test it under a load not just spin it freely
Another video with no dipstick fight. My disappointment is immeasurable and my day is ruined.
Great tear down otherwise!
Not having a rubber timing belt is one reason I waited for the second year 2008 Tundra 5.7 with a chain.
"It's a Toyota, I don't have to do anything to it!"
And then they don't....
You are so right! Ive seen this in many Toyota's and old Mercedes diesels ,they almost always start and run no matter how neglected ,therefore they stay neglected.
Then when it breaks they say, "This thing's a pieca sh**!"
I have this engine in a 1G Sequoia, definitely one of the best engines I've owned. I did a timing belt at 98k miles and it's due again soon. Really great engine.
how many miles do you have on it now??
@@kingmo4653 about 190k miles, it's been an amazing overall vehicle to me
I recently did the timing belt at 155k mi on my 2005 sequoia. Mind you it was on the original timing belt and it looked virtually new. I wonder if it would of lasted 200k but I didn’t want to gamble
@@jamesmaldonado5794 Good call on not gambling. Regardless of belt life, always nice to check the water pump and some of the other bits while you change it. Had a belt break on an old RAV4 once, the worst part was I was turning left at an intersection so I had to push it out of traffic. So can be dangerous for that reason, but towed it home and swapped it out and it ran like new after.
Did a 5.7 starter the other day bro had it straight pipe so couldn't remove the exhaust or manifold shimmed it out and done in just over 2 hours lol, love working on the 4.7 so much better
A tip on removing pistons. Get a piece of schedule 120 1” pipe about 2 foot long you can use it as a driver on the back of the pistons or even on the rod end and even use a 2 lb hammer to force the stuck pistons out with. When the end gets a bit smashed up on the pipe you just trim off the damaged part. I have driven out many a stuck diesel piston out this way
Non interference motor! What a blessing the UZ family has
Toyota's are the best! I have a Prius and a Corolla and both have over 200K miles and run like new! I use Automotive Wolf car care software on my vehicles to monitor the maintenance schedules and have it set up to send me text message reminders when any service is due, so I'm always up-to-date on all the maintenance. Makes a BIG difference. :)
A friend of mine had a 200k plus mile Camry with the og belt! We took the inspection cover off and looked like scales! And he just kept driving it for far to longer than it should have lasted
I have a 05 Tundra with the 4.7 2uz. I only have 156k. My best friend has an 01 Tundra 4.7 with 460k miles. Still runs beautiful with half a million miles. He has always been adamant about maintaining it.
My friends brother in law worked as a tech for Lexus for 20+ years. He said the 4.7 2uz is almost bullet proof. He said he had never seen a timing belt fail on one. He said if you intentionally don't take care of it, it may fail.
10:48 - Magic blue pry bar saves the day yet again!
22:25 Anyone who puts the starter in the valley should be tasked with replacing every single failed starter on that design until they redesign things to put the starter where it's easier to get to.
BMW are bad about obnoxious starter placement too. Even worse idea than this; they embed it in the bellhousing on some models to such a degree that changing it REQUIRES REMOVING THE ENTIRE FUCKING ENGINE!
And people wonder why I love my 37 year old straight six Ford so much. Changing a starter in that thing takes 20 minutes...
I can change a stater in a tundra in 2 hours really not that big of a deal. Intake comes off in about 20 minutes then unbolt the starter. They will almost always make it to 200k miles plus.
Honestly it's not that bad. Inconvenient, yes, but the rest of the engine is so utterly smooth and bulletproof I'll happily deal with the starter for the privilege of driving such a good engine.
@@dawnpoint yew see I have all the same buttery smooth bulletproof goodness too, but I also don't have to deal with tearing the entire induction system off if the starter ever gives me any grief.
My 4.9 I6 runs so smoothly that it won't even vibrate if I yank a plug wire off while it's running. The only sign it's only hitting on five is a change in the exhaust note and a slight decrease in power.
@@TestECull inline 6's are very smooth.
@@jgranger2002 They very much are. The only signs mine has dropped a cylinder is a change in exhaust note and power; the dead miss is not felt at all. It's uncanny. Such a smooth running engine...need more I6s on the road.
Wisemen once said, you can tell a lot about a person within the first 15 seconds. Great Intro, excellent video! It reassures me that I will buy a Tundra.
Just bought my first tundra 4.7 an hour ago. I’m stoked!
What year? I have had a 2005 Tundra with 4.7L since 2014 that I bought with a rebuilt title for $8500. Awesome truck.
You explained well.. you missed something to put the screws on the camshafts.. so that the gear does not turn.. many mechanics who were left behind. They can make a big mistake..
Good thing people don't maintained their vehicles, it keeps everyone in business. Credit cards companies really love these customers.
I used to work for Toyota it’s really odd that people think that a company’s reputation for reliability from the 1990’s and 1980s means that they don’t have to service there vehicles
I have a 17 Dodge Ram 1500 3.6 with 143,344 on it (that’s saying something) that my wife drives for work maintenance speaks volumes.
@Steven Nunez , I have a video on my yt where 2017 Chrysler pacifica with same 3.6 engine has over 500k miles, original engine and no repairs. Check it out if you care, the maintenance on 3.6 was outside of this world.
Can't wait to see unpacking Silver Play Button. Keep up. Congratulations from all your russian viewers and subs.
that's probably the best case scenario for an interference engine. I'm surprised the heads weren't completely destroyed
I really enjoyed this video, and I am not a mechanic. But I am a recent new owner of a 2006 Toyota Tundra Extended Cab with 93K miles and it has the 4.7 engine. This truck came to Pennsylvania from Florida and has very little rust! According to the CarFax, the used car dealer had this Tundra for over a year. I guess I was the only person that was willing to buy a RWD truck. After doing research on the 4.7 engine, I was a little concerned about the timing belt. The CarFax showed that a Toyota dealer replaced the timing belt at 50K miles when the truck was 9 years old. We are only two years away when the Tundra will be 18 years old, and time to consider to have the timing belt changed again. The used car dealer didn't want to change the timing belt/water pump, but they did do some other work that I requested after I took the vehicle to a trusted mechanic. (Spark plugs, valve cover gaskets, wheel alignment and rear view mirror.) I called a Toyota dealer and spoke with the service department and they said that I could have the timing belt checked in two years. I guess there is a way to check it without taking everything apart.
Thanks for a very informative video. Good to know that if the timing belt does break, it doesn't necessarily mean other bad things will happen.
My 03 Sequoia had its first timing belt change at 130,000 miles and it really didnt look that bad.Think I'll change the next one around 210,000. Its been a great trouble free vehicle,I replaced the A/C compressor and radiator last summer and other than regular maintenance thats first real repairs its ever had in 201,000 miles
People are sayin you still might wanna check the water pump at the mileage suggested for the belt.
I have used old Chevy chevette for working and broke trimming belts many times. I have never had catastrophic damage. I could not find a Chevy chevette, so I bought a Honda van and broke a trimming belt and destroyed my van completely. There's no chevettes left, I guess. I used them all up.
It never fails to amaze me how you never seem to encounter problems removing exhaust manifolds. I CONSTANTLY am presented with broken bolts, eroded bolt heads or nuts, etc. that necessitate extracting and or drilling to be able to remove the manifolds.
I assume things tend to go worse for you when the engine is still in the car. I bet using the impact gun is helping things come apart that otherwise would snap while using a ratchet.
Depends on where you live.
Never had an issue with them here in Arkansas, but when I lived in Michigan, go ahead and get out the blue wrench before you even try.
Major difference between living in the salt belt over anywhere else.
@@uasparts Yes that is true. BTW I am in Michigan so.....
@@williamlanphar630 damn, I called that one 😆😆
I am a Flint refugee, living in Little Rock for 18 years now. 👍🏿👍🏿
@@uasparts I'm in South Lyon . Yes you did !
IMO the 2UZ is the best engine Toyota ever made, they can last forever providing you keep to the maintenance schedules. Shame about this one because it could easily have been saved, the engine components look as new.
I am the original owner of an ‘06 LX with this engine with around 794k miles. The truck has been up and down the East coast several times a year for the past 16 years through all sorts of weather and roads. Primarily driven in the Tri-State area. Timing belts have been done every 80k like clockwork to avoid issues such as this, along with the mechanical fan clutch, water pump, and associated tensioners and seals. My wife and I can’t stop driving the truck with how smooth it is. She wishes I got one for her too back in the day haha
Mine broke while idling... it's fine now... no damage internally... I even tried to crank it again after it broke...
Anyway... I tested the compression and then put new H²O pump and misc. other wear parts and cranked it up and drove it...
NOT interference engine unless you're doing 80mph on the interstate and can't stop...
I love the fact that there's no music in these videos so I can play my relaxing classical playlist while watching engines getting dismantled.
At the 16:00 mark watch the exhaust cam scissor gear & you'll see he didn't lock it with a M6x1 bolt.....no biggy, but it'll be a pain on reassembly
I would love to see you tear down a GM high feature V6, preferably an LFX from a Camaro/CTS, I need the intake manifold haha
I too would love to see that. I've worked on most of the variants fitted to the Holden commodores (LE0, LY7, LF1, LFW, LWR, LLT, LFX), and ive owned the LY7 and now LLT, but I would love to see what's inside.
Can't wait to see a 6ve1 tear down. I mean I've got three of them but yea always good content 👍
Congrats on the 100k subs, so cool to see a good channel flourish like this. Question I've always wanted to ask: with filming and everything, how long do these tear-downs take?
For the anniversary a shop tour would be pretty cool
Man, since when has Adam Sandler started tearing down engine's? Hahaha, all jokes aside, been subscribed for years and just noticed you look like Adam Sandler, love the channel, keep up the good work!!!
I have a 2006 Tundra Access Cab, 4 wd, tow package with the 4.7 engine. The truck still looks and runs like new at 130K mile (barely broken in) I am 66 years old and I intend this to be my last truck.....I love it! I have had pick ups since I was 16, this is my best and favorite one yet. At 100K I had the Toy dealer do the timing belt, water pump, all fluids, plugs, trans, transf case, rear end, all new belts and hoses. I change oil every 3K miles with Mobil Super a conv/syn blend and a Mobil 1 oil filter I am sure my truck is set to go to 250K .........my 1996 T-100 did and was still strong.
This is why I like timing chains.
So I have to say that this engine is probably my favorite engine out of all of my vehicles I have ever had. The oil in the engine comes out as clean as the day it was put in. I tow, haul, you name it, it has almost 200k on it. It runs beautiful and has great power. I went to replace the spark plugs the last time and was shocked they still looked like new. It will very likely outlive the truck
The 00 to 04 dont have air injection or vvt, mine has 410,000 miles on it. Doesnt burn or lose oil between changes, has plenty of power and drives like a new truck. Have i replaced suspension and bearings, of course i have. Paid 2500 bucks for it at 300k, sunk another 2500 or so in it, in just parts. I do the labor and it treats me well at over 400k
Great video! I recently picked up a 06 Seqouia. I asked the owner, "So have you done the water pump and timing belt?" His response was, "Huh?". 227k miles and he hadn't done the belt in the "10" years he owned it. I pulled the carfax and turns out, he only had it for 6 years, and the previous owner had done the timing belt. It was still 2 years and 37k miles over the 9/90k interval, but at least it wasn't the original. I replaced the timing belt, water pump, serp belt, tensioners, fan support, and fan clutch and the thing runs great. Thhheeennnn I drained the ATF and it smelt like burnt ass. 😂 3 gallons of ATF drain and fill later it was still dark, but at least it smelled better.
What's atf
@@greekmaster1001 Automatic Transmission Fluid. It should be bright red and smell like funky oil. If it's dark and smells burnt, it needs to be replaced.
You do understand that we partly come just for the "one liners".. 4:24
Eric what I love about watching your show it's if I don't know how an engine comes apart a certain brand I watch yours and you show us how it comes apart fantastic I love watching the videos please keep them going , you do a great job thank you Eric .
That belt was cut. I’ve seen some insane dry rotted belts in those 2UZFE motors in way worse shape and they still held up fine.
I love these engines. Everyone that owns loves them too. Just did the timing belt on mine and now have to do it on my other one. Super smooth. My original belt still looked great after 20 years and 175k.
I did the starter once the worst part is trying to get comfortable getting to it
One thing I have noticed with modern engines is that the high revs on startup it just gets my nerves
My neighbor has a Toyota with the same engine and in the morning when he starts it just takes off revving high for a little while then going to a reasonable idle those high revs must do wonder on oil circulation
To be perfectly honest, this engine is in such good shape (aside from the minor rust in the cylinders) that I'd seriously consider attempting to rebuild it.
I mean, the way it looks to me, more damage was done to this engine by sitting out in the rain than was ever done to it by the timing belt shredding itself.
The main thing you'd need to do to return this particular engine to service would be to give the cylinders a light honing, and to perhaps remove the rust from the pistons by soaking them in Evapo-Rust (that stuff does work, believe it or not, you just gotta give it time), or if you don't have the time for that, putting them in a media blasting cabinet and using fine granulated salt to blast the rust off of them (salt won't damage the finish on the pistons, I don't think. I'd check first, and select an even softer blasting media if needed).
OK, just watched up to roughly 29:00 , and I heard you say several of the piston rings were stuck. That's a new set of rings then, and making sure the ring grooves are thoroughly cleaned out too. Still, that's something I'd check as a matter of routine when rebuilding an engine.
If I had been the mechanic that was repairing the vehicle this engine came out of, I'd have happily put a timing belt in it and sent it on its way (of course, I'd have done both borescope and leak-down tests to check for bent valves first, but since you've taken this thing so far apart and found literally zero evidence of piston to valve contact, I'm confident that it would have passed such testing with flying colors).
Hi Eric,
This is Michael, I live between Springfield, and Joplin, Mo.
I owe older vehicles like a 99 Dodge grand Caravan and had a 94 Chevy S 10 4.3 v6, I’m 54 and in my day I have redone and engine or two now I have a trusty mechanic that does all my work now, I really look forward to your video every Saturday it’s nice to know how these newer vehicles are put together and how people don’t maintain them, I worked for a major oil change place and I’ve done my service manager job now for 15 years and it’s amazing how people drive 8 10 12 15+ thousand miles before doing oil changes or only come in for oil change when their oil light comes on and I mean the little red oil can they comes on saying they have no oil,
Thanks for taking the time every week to make another video for us to enjoy,
If it had alot of mile the valve cover gaskets leak. I have 249k on an original timing belt but I'm buying a new truck next week and I'll be parking this one. I'll get it done before many more miles.
Love watching your tear downs.........kinda hope you can expand into rebuilds and sale of crate engines...........but i know thats also asking alot. Keep up the good work.
“Ballast in the combustion palace” 🤷♂️😆👍 where does he come up with this stuff
Yep, that engine would have ran with a new belt!
I believe the specific industry designation for that sort of coolant passage is "DDD". It stands for double-dong design...for the military it falls under the "don't ask don't tell" rules.
That’s arguably the most reliable engine ever made. If you replace the timing belt.
Really?
Proven as 1 million miles engine in tundra
If they put them in the 100series land cruisers they are about as tough as you can get.
What about a 6.0 liter power stroke or a VW VR6 engine for a tear down? The VR6 would be interesting because it’s essentially a narrow angle v6
Thats a cool aluminum hammer! My Grandpa had a lead hammer and a cast for it for very effective wacking at stubborn parts. It was originally for knocking out wheel knock offs. Whenever it deformed enough we just melted it down and re-cast it. I think I helped him recast it 4 or 5 times. I wish I had it now.
I just subscribed because I watched your take down of the 4.7 iforce engine. Great Video
