Toyota 4.7L 2UZ Total Engine Teardown! Low Compression, But Why? Tundra Land Cruiser Sequoia LX470

[@jossrickard3352]

Toyota mechanic of ten years, I've done four UZ starters in that time. They're not that bad to do, but very reliable overall.

[@derekfriday7931]

I've known a handful of people with uz powered vehicles. I think I knew one who had to replace it. Doesnt seem to be any more reliable/unreliable than a traditional placed starter.

Is that rubber timing belt a problem or is it durable?

[@84Prerunner]

@@albrownmd not a problem, toyota specs 90k replacement intervals but ive heard of people going 200k without issue.

[@dbowen22]

I was just scrolling the comments for a tech to back up the fact that they don't go bad. It's not the hottest part of the engine by any means as ANY other location means that the starter will be next to a ridiculously hot exhaust manifold.

Also it's amazing the amount of abuse and neglect these UZ engines can take and still run fine. I got a LS430 with the 4.3 3UZ in at the dealer like a year ago, vehicle had over 200k on it and the customer had gone almost 10k miles on their oil change interval (factory recommended interval is 5k miles) and came in complaining of a light knocking noise (this car was clapped out and had lived a rough life by how rough it looked). I checked the oil level and was getting nothing on the dipstick. These cars hold 5.5 quarts of oil and I had to put in 4.5 quarts to get the oil level right. This car was running around for who knows how long on only a quart of very dirty overdue oil. I drove the car for a good while after filling it up and did a full oil change and was expecting glitter to come out and the filter to have metal in it and after changing the oil it was veryyyy dirty but no metal in it. Did the second oil change and let it run and the noise went away completely and the customer took it.... mind blown! Love those amazing Toyota/Lexus UZ engines they are extremely under rated especially by people who don't know much about them.

That engine just needs a refresh, clean up the pistons, new rings and bearings and give the bores a bit of a hone and it's probably good for another 20 years with regular use and maintenance. Nice to see a teardown that doesn't end up with confetti in the oilpan,

[@TestECull]

Yeah but I'd rather just not deal with an engine so fragile that sitting for a year destroys it. Why I'm gonna take the 4.6 out of my '99 P-71 Crown Vic and slap a 302 Windsor in instead. Backdate to a more durable engine, throw a manual trans in it while I'm at it, and be done with the matter. Also gonna put a 4bbl carb in instead of messing with EFI; part of why the 4.6 is blown in the first damn place is EFI problems.

[@2006gtobob]

@@TestECull I never had any EFI issues with my '03 P71. What I did have problems with were sparkplug/ignition coil wells filling up with oil. After that was handled, cylinder #3 blew its spark plug out of the head. No. I didn't over torque it. The head barely has 3-4 turns worth of aluminum holding the spark plug in. I bought a heli-coil kit, made the repair on the driveway and it was ok. I sold it at 199,800 miles.

[@TestECull]

@@2006gtobob On mine, the injectors just stopped closing off. It was running stupid rich and getting around 5-7mpg, was stumbling on part throttle cruise and at idle...ran like a hot damn full blast though. At the time I couldn't afford to buy all eight injectors so I parked it and went back to driving my F150...funnily enough I had bought the 'vic so I could do an engine overhaul on that just due to old age...by the time I had saved up and bought injectors the cylinder walls had rusted up about like we see in this engine. I put them in, started it up. It only fired on 7. Puked blue out the back. I took it on a quarter mile testdrive, during which time it drank 3-4 quarts of oil and spat the dipstick out of the tube. Parked it again and it hasn't moved since. Been sitting there for 4 years now while I mulled over what engine I was gonna swap into it since I had to contend with the emissions test in my area plugging into the ECU for a '99. Well, effective Jan 14, 2022, my county of Tennessee is dropping emissions testing, so I'm just gonna slam a 302w 4bbl in it mated to a 5-speed likely yanked out of a Mustang and be done with the matter. No more EFI, no more fragile modern engine, no more automatic trans. Win win win if you ask me. If I don't have to get it sniffed anymore I don't need to worry about all the DTCs it's going to throw when it powers on and doesn't detect that an engine's even in the car. I haven't decided how I'm gonna light it off yet. I might just go points; I'm not building a hotrod here merely getting the car driveable again with an engine I know will last and last. Performance goal is roughly equivalent to the way the 4.6 pulled before it blew up. Points simplify wiring to an almost stupid degree as all I need to do is find a 10 amp KEO circuit and wire that to the coil +, and honestly they're not a big deal to work with on a Windsor V8. But I might also go with a hall effect pickup and an MSD 6AL fender mounted box. Maybe after the swap is done and I've driven it a bit I'll have autozombie pull codes for s's and g's.

There is definitely a market for buckets of brand specific bolts. A local Suzuki 4X4 shop( Trail Tough) has been selling them for years. I bought 2 many years ago. Best purchase I have ever made when I was playing with Sammies.

[@rustypotatos]

I feel the exact same way

[@michaelkrenzer3296]

We tend to fill a Costco coffee can with any vehicle-specific fastenners when we part out a car to supply spares for one of our race cars (usually selling interior and exterior trim then crushing it). Generic stuff just goes the most used 5 cans: metric bolts, metric nuts, SAE bolts, SAE nuts, washers and spacers. At the track we kinda of stage them in a place anyone can get to as other teams ae always asking for XYZ. So yeah, for those that do not part out a car or two every year, model specific bucket of bolts have value for sure. Get into something like a BMW E46 or newer and there are so many specialty nuts, bolts, studs, etc I can image those would have more value than say a late-model Tundra but I could be wrong. I certainly see a niche, discontinued brand like your Suzuki being very valuable. Even the crappy Neon I rehabbed for someone that needed a cheap car getting back on their feet and four bolts on the rear suspension that at least two snap on removal...two of the bolts are $35 each and about a week lead time and the other two are NLA.

There was a coolant line to the throttle body. This is a truck engine, so the throttle plate will see plenty of vacuum, and the throttle body itself may see freezing temperatures as a result, even in the summer; This is why there is a coolant line to warm it up. Light airplanes typically have a carburetor heat knob for this exact purpose.

[@sharedknowledge6640]

Toyota (and Honda) do such a nice job engineering their engines not only to last but to be relatively easy to work on. Compare this to a similar vintage BMW V8 with 200K and all the issues they have (Nikasil anyone?), special tools needed, etc. Even making the coolant crossover pipes castings or steel instead of rubber hoses is a sign of engineering done right instead of shaving every penny out of the design. Despite not having poor maintenance with oil changes all the bearings, journals, and valve train are nearly like new in this engine. Contrast that with a poorly maintained Dodge V8 that spin bearings, drop valve seats, rocker arms fall off, etc. Or the Jeep 4 liter inline 6 that have about 10 PSI of oil pressure when they have even 100K on them (while the fake oil pressure gauge reads normal-they don’t even have an oil pressure sender just a switch).

Remember that this engine was made to go in the Land Cruiser. The location up top keeps it dry and away from water during crossings. They are also known to last 100s of thousands of miles and decades without going out. My 06' 2uz still has oem starter. Pops off like a champ! I also think its part of the design for its versatility. The 2uzfe shares the 1uzfe block in large part. The 1uzfe was designed to go into not only verhicle but airplane and marine applications as well. I think the starter packaging aside from the known benefits assists with this versatile packaging as well.

I found it on this block when I flipped it over. In the rust belt they’re usually pretty rusted shut but I’ll try it next time

[@09corvettezr1]

I suppose I’m spoiled living North of the rust belt

[@Dcc357]

I've seen my fair share of older timing belt engines that run just fine even though they are sludged. Not even a tick noise. They have no variable valve timing, and the timing belt doesn't need oil whereas a chain would get destroyed.

[@rustedratchetgarage6788]

Chains add metal fast which wears mains and rods

Every time a new video pops up my day gets better

[@thomasmiddlebrooke1012]

My biggest gripe with Toyota: the 1MZ-FE (3.0L) and the 3MZ-FE (3.3L) are interference engines with timing belts. Other than that, I'm impressed with the reliability my Toyotas have given me, and how easy they have been to service or repair.

[@mattcat231]

oh i DESPISED the 01 Avalon i had, that 3.0 was an oil burning, detonating, rear head gasket eating nightmare!!! 2 transmission replacements in 99k miles, and when the 3rd one failed at 126,836 miles, I donated that pig to the local fire department for a jaws of life practice vehicle, with the addendum that i be there to make the first cut, and much to my unexpected satisfaction, they also used it as a burn car as well, one of the best days of my life watching that thing get destroyed!!!!

[@jeremynelson8496]

i got a 2uz. It's got 250k on it and the motor runs like the day i bought it. This engine needs to work. It seems like the harder and longer I run this truck the better it performs. The 2uz is not a performance engine but it is reliable af. Edit: failure point=power adders

[@theraf8100]

Failure point = heater t's

[@MichaelAStanhope]

Starter isn’t too terrible to replace, just annoying. Thankfully they don’t go bad too often.

[@Jimrandolph-e7d]

Eric, The next time you have similar rusty cylinder walls, try using some WD40 a few minutes before you scrape them clean with the rings. WD is not only a good rust solvent, but provides some good lubrication, as well.

[@jamesplotkin4674]

Those bearings looked great considering the lack of care this engine received, as far as oil changes. To get this vehicle running well again, I'd put a few ounces of MMO in each cylinder, let it soak for a few days and I bet that would help clear the rings a lot.

[@josephchewning919]

My man bounced a socket like a ball and had to give a slomo replay😂

[@gyffjogofl7676]

The starters rarely ever break. I have 3 with over 300k and have not had one fail.

[@slow_r3188]

The one feeling when I do cars uploads a video you’ve been waiting for for the whole week

[@prevost8686]

The best small V-8 made. 300-400K miles isn’t even noteworthy. After almost 30 years of working on Toyota’s I’ve probably only done six of the starters in the Toyota and Lexus V-8 engines. All had well over 200K miles on them when they failed. I get get 7hrs to replace one so I don’t mind doing them. Only go back with Denso unless you want to do it twice.

[@ronjohnson8119]

But the Autozone starters have a lifetime warranty!! 🙄

[@nickvinten7803]

“…..rust circlips…..”. OMG, laughed out loud at that one. Great one liner !! 👏👏👏

[@tndeere]

I have a 2003 Sequoia and that same engine purs like a kitten..At 198,000 miles it does'nt leak or use a drop of oil and when i change it still looks like golden honey on the dip stick. has had a very good life with great service records. / I'm shooting for 300,000 K.

[@forrestpetersen7400]

You need a small magnate on an extendable rod to get those dropped sockets, reach down and get them back when you drop one.

[@allenbeaulieu7077]

Great video buddy. You make them very interesting with your dialogue. See you on the next one. Big Al.

[@Shirkatron]

@7:46 get the Stealman Pro socket swivel extension set. It’s an 8 in extension with a swivel socket permanently attached. Never lose another socket

[@enthused7591]

I recently picked up a 2003 4Runner with this motor and I feel more and more lucky as the weeks go by to have found a 4WD version of these older 4Runners with this motor and under 190k for cheap. On the hunt to buy a 2nd one as a backup before they become impossible to find.

[@cljvikingpride19]

And the real treat at the end, standing in front of an E34 👌

[@shango066]

At least it doesn't have the secondary air pump and valving in that one. Another pain to replace when it malfunctions

[@IacobucciB]

I’ll vouch for the starters! They’re a lot easier on these than the 1UZ, as the rear coolant crossover blocks your access to the starter bolts, as well as the EGR pipe (don’t believe 2UZ/3UZ had EGR) which the tube always breaks and is a bear to replace. Takes me about half the time to to a truck/ LS430 starter as compared to an LS400 starter

[@erichdiebenow4727]

3uz fe has an egr

[@hassanfakhoury8429]

I've got the same engine on my truck and I will take your advice into consideration to keep it running as long as possible thanks for the video.

[@ChrisR]

Fun Fact: The lead engineer for the cooling system design on this engine was Richard Dicks.

[@zonie1953]

I worry about the location of that starter on my 2007 tundra 4.7 . It is pool service truck here in Phoenix Az . 414,000 miles (mostly city) Truck is running like new at this point 🤞🏼

[@bigfatdavebigfatdave7395]

I’m delighted to see this tear down. I have two 05 sequoias, one with 265k and one with 210k. The engines have been great in both. Mine is used for extensive highway driving while the wife’s just goes to the grocery and short trips. Absolutely love the Sequoia. In both, while replacing valve cover gaskets, i noticed the discolored, glazed situation on the driver’s side of the engines,while the passenger sides were pretty much pristine. This was the situation on both vehicles. Wondering if anyone has insight as to why that would occur. The one with 265k was purchased with 60k on it and the wife’s was purchased with 190k. Since purchase, oil is changed religiously at 4K miles. Love the channel and content

[@Zt3v3]

The PCV system.

[@ryanpeters4316]

Nice e34. I have a 95 540 just like it. 270k and still on daily duty. They're great cars.

[@scottc.1325]

I'm a newbie but I love this channel. Newbie question: How many have commented on how the host looks like Adam Sandler?

[@g2skinny]

Those do run forever if you take care of them I’m a mechanic and years ago it was kinda weird to see a v8 from Toyota used to 4cyl and v6 from them all the time the 1uz was the first one in the Lexus LS and sc 400 used to have an sc pretty cool car

[@joeclarke9782]

Survey Says - Replacing Tundra starter should not cost over $1000. Tundra starters last well up to 75000 miles but after that need for replacement dramatically increases. Its good to have a friend who owns a boneyard. . . I mean auto recycling facility. Thanks for the video.

[@timaugustine-dirt_trippin]

Interesting teardown. I have a GX470 with the VVTI. It's nice to know it will last (if the starter does). Mine has 200k
