The 100 Series is "The Land Cruiser to Buy"

[Devils Paw 80]

I finally watched a couple minutes of video starting around that 30 minute mark. When did Doug own an 80 series? I remember his review of one several years ago.

80 is "Too old and ratty". LOL. Not true in the least, but again I agree with him that the 100 represents the best value in a used LC currently.

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?

Yes/ they will throw the truck into limp mode. The sensors can be replaced independent of the throttle body but it can be difficult to diagnose. Replacing the the throttle body is often cheaper than replacing sensors. It was in my case.

And this is an issue on 98-07 cruisers? Or a particular year?

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.

We are told in the video that the subject 5.7 rig was maintained. So this was not caused by neglect.

Therefore safe to assume it was likely maintained according to Toyota specs (10yr/100k first coolant change). Maybe the damage has already been done by following this schedule? The HG has already started to deteriorate? Are 5.7's less tolerable of Toyota's extended maintenance intervals than other Toyota engines? Will the trend of HG failures observed thus far continue as 5.7s increase in mileage / age?

TCCN conveyed his opinion quite clear in the video - the 3UR is a less reliable and less durable engine than the preceding 4.7L 2UZ.

I’ll agree that the 2uz is probably slightly more durable although I can’t say it’s more reliable.
Just because the 2uz is “more” durable don’t mean the 3ur isn’t durable though. It seems like in this community it’s got to be all or nothing. That’s not the case IRL. With both motors probably outliving the trucks they are in “more” durable becomes a moot point. In reality it just doesn’t affect people.
And as far as “will this trend continue as 5.7s increase in mileage” Well, the milage has already happened. The 3ur has been in 3 platforms since 08. There’s plenty of high mileage Tundras out there.

If guys on this board could snap their fingers and a 3ur appear in their 100s engine compartment they would do it. I think anyone that says they wouldn’t is either being disingenuous or ignorant of the 3ur

It's long but interesting. I'll definitely not be buying a 200 series, or a GX460. There's just no substitute for a cast iron block when it comes to durability and longevity.

Sorry but I disagree. Despite his video, the 5.7 and 4.6 are great motors. Just need coolant maintenance. Truth is they are less cost maintenance than the 4.7. Not saying the 4.7 is a bad motor cause it’s not. But there’s also nothing wrong with the other motors. His video basically tells me that you can have an engine that gets better gas mileage than a 4.7 and 150 extra HP but if you do zero maintenance you may have trouble around 200k miles. I owned both for a while. The 5.7 is a better engine IMO.

Hard to trust anything on these videos anymore. Most of the videos are made to be clickbait and generate views.

FYI there's a few threads in various sections discussing this video.

I wouldn't go that far though. I'd definitely buy a second hand 200 if I was in the market and the price was right. GX460 less so, but that's mostly due to their transmission issues, which are more common as people infrequently service their transmission fluid.

But as a used buyer I would definitely verify that the 200's coolant service was done and that it was done before Toyota's 100k interval. Ideally 5 year / 50k as TCCN recommends. The video seems to hint at the idea that the 5.7 may be less tolerable to Toyota's extended maintenance intervals, and is certainly less durable than the 4.7.

My wife has a 2012 sequoia platinum with 225k miles on it. After we purchased it with 180k miles I noticed it was loosing a little coolant. Did a little research and found out about the valley cover gasket. Redid the sealer around it and haven't had another problem. We just did a 5k mile round trip to the west coast and back. Wouldn't hesitate to drive it anywhere. It's had 0 issues. Very solid truck and engine.

In the context of the broader auto industry they are outstanding. But they're "modern" engines that just aren't going to last as long as the UZ. And when they go the they sometimes take the vehicle with them as the video points out. I'm just very picky about engine durability. I'm not interested in something that can grenade into an end of life / end of vehicle life situation especially with little to no forewarning. The 4.7 meets my standards but it's clear that the 5.7 does not. Who needs that hanging over their head? Of course most people are ignorantly blissful about the potentially fatal weaknesses of their engine. UR engines are about 10 years newer than UZs on average so the failures are occurring at relatively low miles, as the video points out.

cast iron is tougher than alum and can take more abuse. Only way we’ll really know is when they rip apart a million mile 3UR

200-300k is great for modern engines, 2UZs (youngest engine is now 18 years old) have a good amount pushing 400k+ in the high mileage thread.

Again I can deal with parts outside of the engine failing, the actual block itself I would hope to not remove period. The 2 point front diff has been discussed, I wouldn’t put that against the UZ. Mr T should have figured 4 point and did after 00?

There is no perfect engine, but overbuilt? I’ll go with Mr. T in the 90s, after that emissions become the downfall. These smaller 6 cyl tundras, not a fan. Boost only increases pressure in the motor, and then they go alum for weight savings. Bad combo

I had this code pop up and it took me 15-20 minutes to replace the sensor. never had a problem since. also i don't remember this being expensive when I did it 2 years ago, the part was like ~$150. didn't know people were having so much issue with this.

And consider the number of first gen tundras and sequoias and 4runners that ran the 2uz which noone ever reports the high mileage on

 

[Foehammer]

Take even decent care of the 2uz and she'll outlive ya I reckon. Biggest "issue" is the timing belt which once you accept that it's regular maintenance...no big deal.

The head gasket concern is confirmed by some of the 200 owners in the neighbor forum. Many of them are anxiously ordering acidity test strips to double check their coolant For the first time, I start to think Hundy's ancient timing belt technology saves our trucks . (Btw, the new 2025 Honda Pilot still has timing belt. So it's probably not just an antiquated tech...)

I think TCCN lost a lot of fans who own 200 series' as soon as he released that video.

I don’t think so- he’s not a clickbait kind of guy and his advice is solid.

Go read the 200 thread. I agree with you though.
