Yep. There are two release valves on each side of the block.

That small coolant passage between cylinders makes me think that is where problem is, as gasket is probably weakest there. I looked at BMW N55 open deck, and it does not have anything like that.
I'm not sure what the solution is here. It seems not a big enough issue, as engines don't have a bad reputation, and this was not brought up earlier, as these cars have been on the market for 16 years now.
Lower coolant or oil temperature? Idk. I don't have, for example, VCG issues on my BMW, and I attribute that to the radiator type oil cooler I have on it. Maybe running oil cooler like that would help, or 40/60% coolant to help dissipate heat? Bigger radiator and lower temperature thermostat? IDK. Runnin lower temp. thermostat would further worsen mpg which is already the worst in the segment.
I agree.
He brought up warpage but who is to say that the warpage would no be "taken out" by the torque during reinstallation. Maybe they are made that way to "flex to straight" under the proper procedure.
As good as this tech might be, he would not likely be privy to such technical information.
+1, he said on the older 4.7 the issue didn't exist but look at the difference in the gasket. If the aged coolant was the problem why are these engines not blowing the gasket. The difference is night and day as far as the location of the hole between cylinders go
That service is what I did myself. Easier than an oil change and don’t need to remove my skid plates even. Lisle spill free coolant funnel and done.
And the block was cast iron, a much more thermally stable material.
Overheating is the issue, not the coolant IMO.
Who knows. Toyota/Lexus call their transmission fluid a "lifetime" one. The Toyota/Lexus manual is not the Bible. 5 years is long enough for coolant, especially when it's so cheap. Maybe if you're taking it to the dealer for regular maintenance you might be less inclined to cut maintenance intervals in half.

That small hole must weaken integrity of the gasket over time. There isn’t silver bullet here, but maybe 40/60% and more robust oil cooler could help. Also, in video he said modified GX460 is waiting also gasket. I wonder whether modifications caused more heat.
It’s very unlikely an 11 year old car has 200k plus miles.
I had a 7 year old car with 230k, a couple actually. At the same time
If the block is within specs, it is within specs. In the video in question, the block and heads are within specs, case closed. But for him, it is not.
Someone with the experience he has, should not be having these conversations after the fact. He should know all the ins and outs, and have explained every option before the work began.
In his video, he speaks of "well now I am going to have a conversation with the customer". There should be no conversation. There should already be a planned course of action based on the budget of the customer.
Further he says in summary " well it is within spec, but i am not going to warranty the work." This would be problematic for me. If it is in spec, by the automotive godly like engineers at Toyota, who is he to question them?
He touts Toyota quality over all others, but yet has no faith in the specs and the engineering behind the parts and procedures?
That is my perspective. What is yours, since you wanted to know mine?

I still wonder what he's using to measure tenths.
But he's got the right to refuse to warranty the repair based upon experience or instinct. As long as he informs the customer of this up front and the customer agrees, seems to me like a contract between consenting adults.
That said, I might feel obligated to tell the customer I'll charge a nominal diag fee, box everything nicely and help get it to another shop if the customer finds one who claims they will put it back together and stand behind the work. Basically, a goodwill kick-it-down-the-road.
I always try to put myself in the shoes of a distrusting customer, and some might feel now that he's got it he feels he has the customer trapped and can dictate terms, including warranty etc. So I'm always willing to provide an Option B if the customer suddenly thinks they'd prefer another shop.
I've never been in this EXACT situation but when I can see someone is shocked by a quote ‐‐ whether it's mechanical or metal fab -- I make it clear they can take a couple days to think about it and if they want to seek a second opinion/quote I do NOT take that personally. It's just business.

That pretty much accurately describes all our RAM 1500's at work, they were almost all 2011/12's and were at around 200,000 miles by the time they hit ~11 years.
Doesn't that assume everyone has a working knowledge, or better, on just about everything?
If true CEOs could not make decisions that affect production/engineering and the jury system is out the window.
Everyday we collect information from experts (and not-so-experts) and make decisions for ourselves. Some involve more risk than others, but it's life.
Our director drives a '19 Rebel now at 103k miles. So, ~5 years and 100k....if the trend continues you're obviously at 200k in 10 years. In her case, her age might force her to slow down a bit, but that's a very specific variable.
It's pretty easy to click away the miles in the rural west. We sit at very few stoplights so typically if you're in the vehicle, you're moving at least 35-40mph.
I'm always shell-shocked even in Denver when it takes ~40 minutes to go six or seven miles (depending upon time of day)
I know the E coast is way worse! Denver isn't even really bad or that big of a city. I'm just too used to the rural life now -- maybe that makes me "de-institutionalized" like Shawshank in reverse. Or just anti-social

I commute in Phila and it’s not good, but it’s not as bad as NYC, DC, nor Atlanta. The lack of registrations on vehicles and tinted windshields adds to stress though
