Yep, forum seems to be going mad about statistically insignificant issues and assigning it to the wrong cause. Oh well, welcome to the freedom of speech and much non sense on the internet.

I say again, change fluids as you want and drive it like you stole it.
I think we can all agree the 5.7 is a much better motor than what’s rolling off the assembly line today. The V6 V35A-FTS is junk.
That’s what forums do…
Car care nut is an idiot not all uz blocks are cast iron that was only the 2uz which was used in the tundra/LX. The 1uz and the 3uz are all aluminum and have 0 issues. Cars just don't blow headgaskets there is underlying issues that cause this. That's like saying I was just sitting and my arm just broke! Something had to happen for your arm to brake.
I will say it again CCN is a clown that spreads misinformation, just because he is a "master toyota tech" doesn't mean s***. I have met drs when went to school for 10-12 years that where utter garbage.

But YouTube is all I can watch now living in Texas...
With all that’s been said, I know I’m popping the hood to peak under it a little more these days. I’m at 180 k miles. I believe for starters the temp gage needs an upgrade.
Not exactly - not just tundra/lx. But, also LC (obviously), GX, 4Runner and Sequoia.
The 2UZ-FE with the cast iron block was very intentionally designed and chosen to increase durability for Toyota's truck and SUV platforms.
That design decision was not carried over to the 1UR, or the 3UR.
Anyways, back to the head gaskets, this thread is from a MUD member who just pulled their head yesterday, and the head gasket demonstrates the same mode of failure from TCCN video.
A general rule I follow is check your fluids and tires every 2-3 weeks, increases the chance of finding minor issues before they become big ones.

With an obvious valley plate leak, so there’s no real mystery what the cause was.
I don't follow your line of reasoning. What was the cause exactly?
Are you saying it overheated? Because I didn't see that mentioned in his thread (yet... I asked for more details)

Even without an obvious overheat, it most likely had air in the cooling system.
Whatever the mode, it was not a healthy cooling system, so it doesn't support the guy's argument.
So, a small coolant leak (even if periodically topped off), that causes no obvious overheat - blows the head gasket? Yikes.
If this is the case then what does that say about overall durability and reliability of the UR compared to the UZ? (Which was TCCN’s less than subtle ”other” argument)
Given that many 200’s are likely to encounter coolant leaks since many of them were a) supplied with a defective radiator from the factory that will eventually leak, or b), will encounter the quite common valley plate leak - chances are that many of these have been, or will, enter an unhealthy state at some point.
IMO, for any prospective used buyers, it makes looking at a higher mileage 200 a bit riskier of a proposition than one may have originally thought.

Cool, that leaves more great vehicles for everyone else.
You either pay a little preventative maintenance, lose $20k + on new car depreciation or trips to the dealer with a domestic full size SUV.
Pick your poison…. I choose 200 series and what I save in insurance, property taxes and lower depreciation more than pays for the little bit of extra maintenance I will incur compared to a new/ newer LC250 or suburban or f150.
If it’s about saving money buy a Camry. If it’s about saving money but need 4wd buy a 5th gen runner….

Toyota followed American manufacturers leads with the cast iron block for there trucks/suv's thats why the 2uz has a cast iron block. The 3uz, 2uz, 1uz have interchangeable parts and are almost the same give or take.
I personally have been using 3uz's for over 15ish years have had 0 issues and they are all aluminum. If the aluminum block and toyota coolant eating away headgaskets was an issue every 3uz I have had would have blown a headgasket by now. Your letting some guy on YouTube who is making money off you tell you misinformation and you are believing it.
Things just do not brake at random doesn't matter cars the body homes etc. There is almost always some underlying factor that causes these issues.
Yeah recently... its been a *(*&*&(*)(*) here
Above all else this holds the most truth.

So please explain to me how owning a Prado was a mistake. Have you ever owned a RHD 4.0l V6 late model Prado? Have you ever lived in Australia and seen how they use their off road vehicles? Experienced Fraser Island ?
We did all of the above during a 3 month getaway, and were busy every day exploring from Sydney to Port Douglas, and everything in between, and the Prado we bought instead of renting for 3 months, was a stout vehicle that proved itself numerous times, so where did you read we had made mistakes ?
Just curious what you might have been smoking or drinking to make the comment, but then again, we ALL make mistakes right??
His reply is what we affectionately call "satire" in the US.
Give it a burl. You may find it grouse/ripper.
I had to look up the middle line of my reply. I hope you appreciate my herculean efforts.
