Sorry. As the current owner of three 3urs ranging from 200k to 285k I didn’t find it informative in regards to the 3ur. If anything I found it misleading.
Head gaskets are not a common issue with the 3ur anymore than they are with the 2uz.
Just curious what you found informative?
Also it’s confusing that he mentioned the GX several times as having the same motor and it’s never had the 3ur🤷🏻‍♂️

What's confusing about it? The GX has the 1UR engine which is incredibly similar to the 3UR engine (same engine family). The main difference being the 1UR's shorter cylinder stroke. Both engines share in design, architecture, cylinder bore, and they also share tons of parts.

They also share the exact same head gasket.

Thanks for clarifying. I was so fixated on what the guy that posted the video said that I thought he was just bashing the 3ur. I didn’t realize he was bashing the entire UR family 👍
 
He also states it in one of the videos that it seems to be cause by long times between coolant exchanges, well maintained ones don't seem to have this happening. Also shows the coolant hole between cyls 5-7 being the constant weak spot.

Don't think it's bashing. Both are fine engines. But 1 is superior to the other as echoed by TCCN in the video.
 
He said always cylinders 5 and 7 or both are failing. 2UZ dont have a one common failure spot. I can accept a failed head gasket for insufficient coolant levels, but an engine starts burning coolant because it is old is unacceptable. Also the block is wrapping makes a simple head job a complete major overhaul costing US$ 23K.

MO opinion the 3UR is, but this video seems to insinuate otherwise 🤷🏻‍♂️
UZ motors are king for reliability, no doubt about it.
No doiubt. I believe the 2uz will outlast a 3ur but both will outlive the vehicles so it’s kind of a moot point.

This isn’t a common 3UR issue. It’s not anymore common than head gasket issues on a 2uz.
Also if you do hwve an issue (and you likely won’t) it’s not gonna be 23k. The salvage yards are full of Tundra and Sequoia 3urs. They can be had for relatively cheap. It’s mind numbing that this guy doesn’t offer that as an option to his clients or viewers. 🤷🏻‍♂️

The $23k figure seems pretty ridiculous considering:


You’d probably be better off with a used stock engine, than a “race engine” full of aftermarket parts, in a daily driver, but if I’m paying $23k, I’d want a significant power upgrade (2UZ, or 3UR).

TCCN himself says that 5.7s with blown head gaskets are becoming a trending theme - this was basically the entire point of the video...

He has 4 URs in the shop right now with this issue. 2 more scheduled to come in. Has seen multiple of these with the 5.7 in the past.

This mode of failure is definitely more common than on a 2UZ.

I’m saying it’s not a common problem with well maintained URs. If someone doesn’t change or check their coolant in 15 years bad things will happen. Regardless of the motor

There are way more URs on the highway then there are UZs. So there will be more failures .

UZs likely have more coolant checks and replacements due to timing belt services. The UR doesn’t have that.

Basically take care of the motor and this won’t happen. The 3ur is spectacular and 380hp is worth changing and checking the coolant imo.

I know I’m not worried about any of mine.
 
There's no doubt the UR is an upgrade over the UZ. I picked a UZ because I didn't need the HP and didn't want to deal with the following "common" or not problems.
Cam tower leaks
Timing Chain cold start rattles/oil leak
Valley Plate/heater exchange leak

as URs age I would assume we will see more and more of this pop-up. Remember anyone who goes by what the dealer told them(Extended fluid change intervals)... these issues will likely come up, which is his reasoning for not warranting junkyard engines.

This is a single point of failure across multiple engines in his shop, polishing cyl 7 w/blown gasket near coolant exchange hole between 5&7. No signs of major overheating, minor overheating possible and loss of coolant prior. Possible warped block(terrible hopefully least likely outcome). I don't believe we have this on the UZ platform.

On the fluid change intervals he had a video, why 10k oil changes can be a problem, you don't know what is actually happening on the piston rings and if deposits are getting stuck there, took apart a Camry(10k intervals) that slowly started burning more and more oil after 100k miles, by almost 300k it was up to 2+qts every 1k. The rings were frozen. Same engine will have no problem doing 500k+ with 3-5k intervals. He has seen multiple of both type frequent changes no problems, long changes with problems later.

So if people go by the information a dealership gives them, 10k oil change, life time ATF, etc. When problems happen should we consider them common problems? I'd say so.

That being said, my next purchase will almost certainly be a 200.

Edit: and this week we had a member post recently about his 100 with 325k on a T-belt and water pump. He noted he changed fluids at regular intervals.

I hear ya, but you are ignoring drawbacks to the UZ.
  • Common exhaust leak issue
  • Common Valve Cover gasket issue
  • Timing belt service every 80K
  • Common Aps/Tps issue
  • Common heater tee failure that has killed many a UZ
So when you factor that its I don't see how the UZ comes out on top.

If you are the average person that doesn't top their own work you are gonna be in 3 TB services before you would even have to think about the timing chain. And 3 services at a stop are gonna run $3600-$6000.

As far as cam towers go I would say that goes right along with the common valve cover/exhaust leak issues with the UZ. Plus if you do have to do cam towers you can service timing chain and tensioner while in there.

I think they are both great motors. Im not knocking the UZ, but looking at what I list above tell me how the UZ comes out on top?

All in all the 100 cost ALOT more to maintain than a 200. Bearing repacks every 30k plus the timing belt every 80k really adds up for most people. Both are not a thing with the 200.

1)you could stack valley plate and cam towers against exhaust headers, also won’t kill your engine, put 50k on a 4R with bad headers. Both current UZs in my driveway are quiet.

2) this is minor, most are loose, easy to get to, 2 banana job?

3)I’ll trade the TB jobs vs the timing chain problems. The trade off for me is how much smoother it feels. Planned work vs unexpected crap.

4) I haven’t had any experience with this on any of my 2UZs so far, haven’t dug into this issue. You could argue the faulty fuse box, NAV PIN problems that can plague some 100s.

5) Id argue the same as coolant flushing a UR. Won’t happen if you stay on top of maintenance.

Wheel bearings and torsion bars might be the biggest knock on the 100.

It depends on what you like/want/need, neither of these platforms are cheap let’s be honest. Both have pros and cons and I’d happily drive either.

I would still pick the UZ because I have experience with it. Maybe in 10years I’ll pick the UR after it’s in my driveway.

2) If you know 2uzs then you know thats only a short fix. The bolts don't back out, the gasket shrinks/degrades over time. Once the leak presents the only real fix is replacing them.

You forgot to add the VERY common catastrophic front diff failure on the 100. 200 fronts don't fail. And I don't have a problem with the TBs per se, its the terrible front end travel that sucks.

Oh and as far as staying on top of maintenance for the heater Ts how would someone not in this community or forum know about that? AFAIK it's not a scheduled maintenance item by Toyota. Those Ts go and you have a catastrophic failure on your hands. The 3ur in the LC doesn't have any problrem that common that could lead to a catastrophic failure. Cam towers and valley leaks aren't gonna cause a failure so quickly, there will be plenty of warning.

You bring up a good point that 100 owners don’t touch on often. I’ve seen multiple post 99 owners who’ve blown their front diffs. Also don’t forget about throttle body failures. That’s becoming a more common issue on the later 100’s and is not cheap. At least it’s an easier fix.
 
Auto position sensor and throttle position sensor? What exactly goes wrong with it; they just give out? And then whole throttle body needs to be replaced?
