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.
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
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
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.
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. 🇨🇦🥃
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.
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?
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"
I just purchased a 2005 Sequoia at a salvage auction with 363,000 miles on it. It turned out to be a one owner car. I couldn't find a sticker in the engine bay to indicate when the timing belt was most recently changed so I called the previous owner. He was very nice a proceeded to tell me the only thing he ever changed on it was the radiator and maybe the alternator but never the timing belt. Needless to say, I'm not even going to start the car one more time until I change that belt. It's hard to believe the belt lasted that long but he did say it was a lot of freeway miles.
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
That’s a dream 😍 I can’t even imagine how amazing it would be to be buying a new vehicle in that era. I was born in 1997 and I’ve only ever driven Toyota and Lexus vehicles 18+ years old, currently on a 2006 sequoia. I absolutely hate new vehicles, and all I dream of is a rust free 2UZ-FE SUV one day.
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...
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
I bought a 2001 Sequoia with 151k miles. Couldn't find any stickers saying if or when the belt was changed, so I bought the kit and with the help of RUclipsrs. I did the job and so glad I did. The belt was obviously original and cracks all over. There's a sticker on it now.
My dad drove his first gen tundra to the ground. He was ready to junk the truck over a water pump and a timing belt. He said the truck wasn't worth investing any $. I just replaced water pump and timing belt and the Tundra runs great again. Free Truck!😎
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.
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.
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.
@@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.
My boy bought a 2004 Crew Cab Tundra for $800 because it had a broken timing belt. Valves were minimally bent - only really seen with a flashlight with the head off. Re-valved, re-seated, and changed a lot of wear items, and oil pump - he is driving it to school daily - truck has over 350k miles on it. Love the Toyota. My wife and I have a Gen 3 with 140k miles on it. Great vehicles that never miss a gas station.
My wife’s 99 landcruiser went 315k , we sold it running great. These motors are bulletproof. The only weak spot is the starter every 125k miles, it took me 7 hours to change it. Deep under the intake manifold.
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,
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
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.
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
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.
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. :)
I had a 2000 tundra, timing belt broke at 225,000, starter went out at 275,00 then got totaled from hail at 345,000. Fantastic motor! Great channel thanks for sharing your knowledge
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.
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.
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.
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.
If the mechanic has any idea about Toyota engines should know this is a bulletproof engine, this not an interference engine ……. It looks intimidating for a non professional mechanic but this is a sweet hart❤of an engine …..
I have an 04 Tundra 4.7 non vvt. It blew the timing belt at highway speed. Is this engine a non interference?? It was the 2nd timing belt, installed around 220,000ish miles. It currently has around 258,000 + - a couple 1,000. Could I be able to install a new belt and be good?? Bought in 06, 56,000 miles. I love this truck. FIRST time she has ever broke down! She has ran like new for 16 years. Pulled many tons over the years. Always maintained, almost original everything . Interior is excellent, even with 5 kids and 4 dogs. I just had the front end suspension completely re done. January $2,500 invested in it. We live in Colorado mountains rough dirt roads, moving to Missouri. Belt broke in Kansas. My wife has a 02 sequoia with 305,000 miles, 3rd belt.
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
For clarification, yes the purpose of the top mounted starter is Toyota reliability by design. It is placed at the highest point of the flywheel when crossing deep water or flooded bush country. Unlike Detroit products low bell housing fail. Fortunately, the Detroit designs keep you in business! Pay attention or pay cash!
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.
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!
Why do you have more than 100k subscribers? Dry humor. Informative. Humble. And you show nearly everything. You don't skip things. Also, no shameless promo plugs and advertisements except for your own shop which isn't shameless at all. I can't stand the number of folks that are now doing advertisements AND have a subscription plan. Keep up the good work, my dude. I'm incredibly glad I stumbled across your channel one day. Always a good time when I see that Sub Update that tells me you've posted a new video.
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
Recently bought a 2006, 255K mi. Tundra with last known T-belt change at 134K. I'm an old school mechanic with little Toyota experience. Your video was tops. No bull, to the point and humorous. (like the Ford comment). I noticed you remove cam, crank, intakes, heads, etc. in reverse torque sequence order. Great job.
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.
I had my 2001 Sequoia timing belt break at 180,000 miles. I had the original changed at 95,000 and it looked perfect when it was changed. The 2nd belt broke at freeway speeds and I thought the engine was toast! I was devastated. I called my Toyota Dealer and then said the engine was toast. I took the Sequoia to the shop that changed my original timing belt and they said they've had good luck with broken timing belts on the 4.7 and no damage to the valves. So I held my breath and asked them to change the belt. Turned out the engine was totally fine. Timing belt broke the cam sensor and so with a replaced cam sensor, water pump, timing belt - repair cost was about $1000.00. I now have 20,000 more miles on the same engine and it runs beautifully! I don't know if I was lucky or what...but that was my story. Love my Sequoia!!!
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.
@@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.
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
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 :)
I know a guy that installed the timing belt incorrectly with one cam off about 20 degrees. He got all kinds of lights and it missed horribly. He called me AFTER he drove it that way to the Toyota dealership who told him the engine was junk now and quoted him $9000 for a new engine. I told him bring it home (drive SLOWLY) as the "damage" was done. I told him start pulling it down and I will come over and help you time it. Timed it, buttoned it up, reset the computer, and it started and ran perfectly and has for over 65,000 miles. 2005 GX470 4.7 VVTI.
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 .
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.
@@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.
I am the original owner of a 2001. I replaced the timing belt, water pump and thermostat at 131K miles when the parts still looked brand new. Only 155K miles now so it still runs like new. Parked outside so white paint is fading. If maintained properly after I'm gone, I expect my daughter's grandkids to still be driving it as a vintage Toyota SUV.
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
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.
I really enjoy watching your videos Eric. Very relaxing to watch, very entertaining and great humour 👍 I worked as a casting die maintenance technician at Toyota UK for many years. The engines are designed and engineered very well (well, better than most anyway - but let's not talk about the '3 corner joint' on ZZ engine!) and we had very high quality control. We made ZZ, SZ and ZR engines (didn't make these big engines, only the little ones 😂) It's such a shame that they didn't investigate and check this engine out properly before replacing it. It could have run many more miles with just a timing reset and new belt. Pity about the water damage in the bores. I'm sure you'll get a good return on the other parts tho 👍
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.
First thing I done after I bought my 2002 tundra was have the belt changed , they told me they changed it and after taking a peek through the cover I knew they lied . .. it’s a absolutely great engine but you have to stay on top on maintenance
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 .
First car i ever test drove on my own when i finally made enough money to even look at new cars was a 07 Monte SS just like the one behind you. That thing put you in your seat when you stepped on it. Got the 04 instead. Would love to see a 3.8 V6
In my country, there was 1 Million Miles Toyota Avanza with 2NR-FE engine, just change Water Pump 4 times, and at 1 million miles just need changes Piston Ring, and no more smokes out of exhaust.
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 am on my second 2006 Tundra with this engine. First one ran past 250K on the OD with never going to the dealer even once. I found another a few years ago that was a "Grandpa" truck with 62K and it now has 125K. Again, never once to the dealer but for timing belts. I run Blackstone oil analysis and both trucks get a 100%/AAA+ review by their tech. Great motor and I get 17019 MPG (both trucks are double cabs with shells on the back). Great video - thanks. Bob in Nevada
@@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.
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.
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.
It’s funny how you make tearing down an engine interesting and enjoyable to watch, Some might even say it’s like watching paint dry I really enjoy it thanks
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 .
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.
2uz is generally a non interference engine, only the vvti had issues. I had a timing belt snap on my 99 100 series half way between phx and austin. towed it back to phx and ended up having a local shop do the timing belt. runs like a top, no damage.
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.
That's interesting, I was thinking all Toyota engines were non-interference -- that's why I didn't think you'd find any bent valves. I guess I learned something new.
Most of all of the Toyota t belt motors are non interference with a few exceptions the 1uzfe in the ls400/ls430/gs cars and the vvt 4.7 in the tundra/sequoia and the 1 or 2 jz inline 6 engines in Lexus cars.
I've torn several engines down, including the 355 in my '75 Z28, that lost a set of valve keys, valve fell into the cylinder, snapped the head off of it, and stamped it into the top of the piston...yet here I sit, watching engine after engine tear down. Perhaps I'll call it therapy...
I've seen these engines with 350k+ miles on them, and still running strong, if they are taken care of. The 5.7 starter is pretty easy after you done a couple.
As an owner of an '86 Toyota Camry who did the same thing (Timing belt? You mean it doesn't have a timing chain? And it has to be changed?) but lucked out because it was a non-interference two valve engine, I'm not going to call the owner an idiot, but when you own something, you have the freedom to do what you want with it, but also have the responsibility to maintain it too.
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.
@@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.
I took mine to the dealer with 213,000 and told them I wanted belt, water pump, tensioner and all pulleys replaced. When I picked it up all they changed was the belt and water pump because the mechanic said " the rest looked pretty good". If I wanted shade tree work done I wouldn't have paid dealer labor.
I own an 03 Tundra with the 4.7 with a 177,000 on the clock, I've changed the oil every 4,000 miles since it was new, and I replaced the timing belt myself at 160,000. I know it was way overdue, but I got lucky, I guess. It's been an extremely reliable truck with almost no issues buy I did notice the engine your working seems to have way more hoses and emission crap attached. Anyway, love your channel, and it's great how you and Ray are helping that family with the minivan, not a big fan of Chrysler products.
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 ;-)
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.
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.
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.
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
I just purchased a 2005 Sequoia at a salvage auction with 363,000 miles on it. It turned out to be a one owner car. I couldn't find a sticker in the engine bay to indicate when the timing belt was most recently changed so I called the previous owner. He was very nice a proceeded to tell me the only thing he ever changed on it was the radiator and maybe the alternator but never the timing belt. Needless to say, I'm not even going to start the car one more time until I change that belt. It's hard to believe the belt lasted that long but he did say it was a lot of freeway miles.
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
That’s a dream 😍
I can’t even imagine how amazing it would be to be buying a new vehicle in that era. I was born in 1997 and I’ve only ever driven Toyota and Lexus vehicles 18+ years old, currently on a 2006 sequoia. I absolutely hate new vehicles, and all I dream of is a rust free 2UZ-FE SUV one day.
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
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
I bought a 2001 Sequoia with 151k miles. Couldn't find any stickers saying if or when the belt was changed, so I bought the kit and with the help of RUclipsrs. I did the job and so glad I did. The belt was obviously original and cracks all over. There's a sticker on it now.
My dad drove his first gen tundra to the ground. He was ready to junk the truck over a water pump and a timing belt. He said the truck wasn't worth investing any $. I just replaced water pump and timing belt and the Tundra runs great again. Free Truck!😎
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 $1000 for preventative maintenance
that engine is an example of all toyota owners. they last forever..
@@harrywalker5836 I agree with you, my FJ Cruiser is twelve years old and runs like new.
You are right about the starters on this motor. I've sold car parts for 14 years and have never sold a starter for a Toyota 4.7.
Mine went around 130,000
This and Northstars, even if they do fail, pulling intakes on these vehicles isn't as hard as getting the exhaust out of the way on a lot of other vehicles.
As an owner of a 2002 Tundra with the 4.7L, I am astounded with the smoothness and reliability of this engine--even after 235,000 miles. I've owned other V8's and, so far, nothing has come close to the build quality of 2UZ. You're teardown proves that.
😂 plenty of v8s are smooth at 300k
@@ChrisB-cx6td oh yea? What v8 do u got that has 300k miles on it everything original but spark plugs that DOESNT burn a drop of oil either? Fool.
I miss my 01. I panicked and sold it at 75,000 miles because of fuel prices.
I'd rather pay an extra 100$ 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.
My boy bought a 2004 Crew Cab Tundra for $800 because it had a broken timing belt. Valves were minimally bent - only really seen with a flashlight with the head off. Re-valved, re-seated, and changed a lot of wear items, and oil pump - he is driving it to school daily - truck has over 350k miles on it. Love the Toyota. My wife and I have a Gen 3 with 140k miles on it. Great vehicles that never miss a gas station.
Don’t let Scotty see this he might have a heart attack
My wife’s 99 landcruiser went 315k , we sold it running great. These motors are bulletproof. The only weak spot is the starter every 125k miles, it took me 7 hours to change it. Deep under the intake manifold.
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,
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
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.
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
Best V-8 engine known to man when maintained!
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.
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.
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
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. :)
I had a 2000 tundra, timing belt broke at 225,000, starter went out at 275,00 then got totaled from hail at 345,000. Fantastic motor! Great channel thanks for sharing your knowledge
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.
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 !
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.
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 😎😉
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.
Had 597,000 miles on my 2000 tundra. My belt went while I was driving on the Hwy. Loved that truck!
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.
Just picked up a 2001 Sequoia with the beloved 2UZ. It's been 3 weeks and I love it so far. Went from a 5VZ 4runner
About to change mine, I believe it still has the original belt (220,000 mile)
If the mechanic has any idea about Toyota engines should know this is a bulletproof engine, this not an interference engine ……. It looks intimidating for a non professional mechanic but this is a sweet hart❤of an engine …..
I have an 04 Tundra 4.7 non vvt. It blew the timing belt at highway speed. Is this engine a non interference??
It was the 2nd timing belt, installed around 220,000ish miles. It currently has around 258,000 + - a couple 1,000.
Could I be able to install a new belt and be good??
Bought in 06, 56,000 miles. I love this truck. FIRST time she has ever broke down! She has ran like new for 16 years. Pulled many tons over the years.
Always maintained, almost original everything . Interior is excellent, even with 5 kids and 4 dogs.
I just had the front end suspension completely re done. January $2,500 invested in it. We live in Colorado mountains rough dirt roads, moving to Missouri. Belt broke in Kansas.
My wife has a 02 sequoia with 305,000 miles, 3rd belt.
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
For clarification, yes the purpose of the top mounted starter is Toyota reliability by design. It is placed at the highest point of the flywheel when crossing deep water or flooded bush country. Unlike Detroit products low bell housing fail. Fortunately, the Detroit designs keep you in business! Pay attention or pay cash!
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.
Just bought a super clean 2005 with 105k mi and loving this engine.
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.
Why do you have more than 100k subscribers? Dry humor. Informative. Humble. And you show nearly everything. You don't skip things. Also, no shameless promo plugs and advertisements except for your own shop which isn't shameless at all. I can't stand the number of folks that are now doing advertisements AND have a subscription plan.
Keep up the good work, my dude. I'm incredibly glad I stumbled across your channel one day. Always a good time when I see that Sub Update that tells me you've posted a new video.
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.
Recently bought a 2006, 255K mi. Tundra with last known T-belt change at 134K. I'm an old school mechanic with little Toyota experience. Your video was tops. No bull, to the point and humorous. (like the Ford comment). I noticed you remove cam, crank, intakes, heads, etc. in reverse torque sequence order. Great job.
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 had my 2001 Sequoia timing belt break at 180,000 miles. I had the original changed at 95,000 and it looked perfect when it was changed. The 2nd belt broke at freeway speeds and I thought the engine was toast! I was devastated. I called my Toyota Dealer and then said the engine was toast. I took the Sequoia to the shop that changed my original timing belt and they said they've had good luck with broken timing belts on the 4.7 and no damage to the valves. So I held my breath and asked them to change the belt. Turned out the engine was totally fine. Timing belt broke the cam sensor and so with a replaced cam sensor, water pump, timing belt - repair cost was about $1000.00. I now have 20,000 more miles on the same engine and it runs beautifully! I don't know if I was lucky or what...but that was my story. Love my Sequoia!!!
bit scary that thetiming belt snapped because usually they last longer than you would expect
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.
Cool , Congratulations on the 100K Subs (103K) as of now , love the tear downs , Keep them coming !
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.
Should've thrown the crank-bolt back in and turned the short block over with a power-bar... @ 24:15
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😂
I know a guy that installed the timing belt incorrectly with one cam off about 20 degrees. He got all kinds of lights and it missed horribly. He called me AFTER he drove it that way to the Toyota dealership who told him the engine was junk now and quoted him $9000 for a new engine. I told him bring it home (drive SLOWLY) as the "damage" was done. I told him start pulling it down and I will come over and help you time it. Timed it, buttoned it up, reset the computer, and it started and ran perfectly and has for over 65,000 miles.

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 .
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.
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.
I am the original owner of a 2001. I replaced the timing belt, water pump and thermostat at 131K miles when the parts still looked brand new. Only 155K miles now so it still runs like new. Parked outside so white paint is fading. If maintained properly after I'm gone, I expect my daughter's grandkids to still be driving it as a vintage Toyota SUV.
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
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.
I really enjoy watching your videos Eric. Very relaxing to watch, very entertaining and great humour 👍
I worked as a casting die maintenance technician at Toyota UK for many years. The engines are designed and engineered very well (well, better than most anyway - but let's not talk about the '3 corner joint' on ZZ engine!) and we had very high quality control. We made ZZ, SZ and ZR engines (didn't make these big engines, only the little ones 😂)
It's such a shame that they didn't investigate and check this engine out properly before replacing it. It could have run many more miles with just a timing reset and new belt.
Pity about the water damage in the bores.
I'm sure you'll get a good return on the other parts tho 👍
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.
First thing I done after I bought my 2002 tundra was have the belt changed , they told me they changed it and after taking a peek through the cover I knew they lied . .. it’s a absolutely great engine but you have to stay on top on maintenance
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 .
First car i ever test drove on my own when i finally made enough money to even look at new cars was a 07 Monte SS just like the one behind you. That thing put you in your seat when you stepped on it. Got the 04 instead. Would love to see a 3.8 V6
i have a 2uzfe in an 03 which is pre vvt but i currently have 330k miles on it and it still runs like the day it was bought.
anyone catch the bolt falling into the intake port when the intake was removed?
Thanks for the demonstration that belts don't belong on interference engines unless they're in a racing engine getting regular teardowns.
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 my country, there was 1 Million Miles Toyota Avanza with 2NR-FE engine, just change Water Pump 4 times, and at 1 million miles just need changes Piston Ring, and no more smokes out of exhaust.
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 am on my second 2006 Tundra with this engine. First one ran past 250K on the OD with never going to the dealer even once. I found another a few years ago that was a "Grandpa" truck with 62K and it now has 125K. Again, never once to the dealer but for timing belts. I run Blackstone oil analysis and both trucks get a 100%/AAA+ review by their tech. Great motor and I get 17019 MPG (both trucks are double cabs with shells on the back). Great video - thanks.

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 do my belts every 95K, approaching 300K and it is just such an amazing engine.
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.
My 02 Tundra spark plugs did the same weird thing, and the threads looked the same. Creak creak creak. 110k miles on them :D
Crank looks good makes me wonder if the block and all pistons were cleaned if it would run with orginal heads and just a new timing belt 🤔
I saw a 2003 land cruiser go 285k on the original belt. It was a 1 owner and he verified it had not been done. I was amazed!
It’s funny how you make tearing down an engine interesting and enjoyable to watch,
Some might even say it’s like watching paint dry I really enjoy it thanks
To think... When I subscribed you had roughly 35K, and now you have over 100K Congrats man. Thanks for the content.
The editing and use of fast forward on this channel second to none.
I have an 01 Sequoia with 350000, just did the belt & water pump. Still runs great
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 .
I worked in a shop for many years. One of my co-workers did a timing belt on a 4.7, started it up and it blew up.
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
2uz is generally a non interference engine, only the vvti had issues. I had a timing belt snap on my 99 100 series half way between phx and austin. towed it back to phx and ended up having a local shop do the timing belt. runs like a top, no damage.
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.
I’m doing the SA Pump right now. Really don’t want to replace the starter just to replace it… but it’s tempting.
That's interesting, I was thinking all Toyota engines were non-interference -- that's why I didn't think you'd find any bent valves. I guess I learned something new.
Most of all of the Toyota t belt motors are non interference with a few exceptions the 1uzfe in the ls400/ls430/gs cars and the vvt 4.7 in the tundra/sequoia and the 1 or 2 jz inline 6 engines in Lexus cars.
@@jgranger2002 the 2jz is only interference if it's the vvti motor. The non-vvti is non interference.
I agree. All but the famous 2js.
@@jgranger2002 94 and below 1uz is non interference, after that year theyre interference
@@jza80king thank you for the correction the vvt I6 motors are interference.
Don't ever worry about "shameless" plugs - if it keeps bringing us videos like this. Another great job. Already cant wait for next week.....
I've torn several engines down, including the 355 in my '75 Z28, that lost a set of valve keys, valve fell into the cylinder, snapped the head off of it, and stamped it into the top of the piston...yet here I sit, watching engine after engine tear down. Perhaps I'll call it therapy...
Just changed my timing belt on ten 04 tundra , for the 2nd time, once at a 100k and recently at 200k. I love my truck!
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.
I've seen these engines with 350k+ miles on them, and still running strong, if they are taken care of. The 5.7 starter is pretty easy after you done a couple.
Yes, starter pretty easy, if only it's GM 5.7:)
@@ДмитрийФакухин or 5.3
358k mi on my 1uz.
As an owner of an '86 Toyota Camry who did the same thing (Timing belt? You mean it doesn't have a timing chain? And it has to be changed?) but lucked out because it was a non-interference two valve engine, I'm not going to call the owner an idiot, but when you own something, you have the freedom to do what you want with it, but also have the responsibility to maintain it too.
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.
I took mine to the dealer with 213,000 and told them I wanted belt, water pump, tensioner and all pulleys replaced. When I picked it up all they changed was the belt and water pump because the mechanic said " the rest looked pretty good". If I wanted shade tree work done I wouldn't have paid dealer labor.
Thank you Eric - love watching the video on my favorite Toyota V8. Have one in a 4Runner I own and its solid and dependable.
I own an 03 Tundra with the 4.7 with a 177,000 on the clock, I've changed the oil every 4,000 miles since it was new, and I replaced the timing belt myself at 160,000. I know it was way overdue, but I got lucky, I guess. It's been an extremely reliable truck with almost no issues buy I did notice the engine your working seems to have way more hoses and emission crap attached. Anyway, love your channel, and it's great how you and Ray are helping that family with the minivan, not a big fan of Chrysler products.
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 can tell that you really enjoy tearing these bad boys down ! - Best wishes for 2023 - Keep all the great videos coming man. 👍👍👍
Yep, a leakdown test would have cleared this engine for further use with a new timing belt. Oh, well.....thanks for an informative video!
