6k mile oil changes... and consistent coolant flushes... saves your heater core, AND water pump... toyotas COOLANT has CHEMICALS IN IT to help with lubrication... but if old an go bad he's right the coolant will get acidic. " Toyota recommends flushing the coolant in a vehicle every 30,000 miles or every two years. However, the interval may vary depending on the type of coolant used in the vehicle".

[@Tiberius_I]

Yeah, me too - this same video made me realize yet again, how very unwise it is to actually take seriously the manuf "recommended service intervals" as they are far too long! I have a 2017 Lexus LS460 and had only 69,500 miles when I bought last year (for $36,500) - which means the car is new enough, that most maintenance I do will pay off long-term. There's no such thing as "lifetime" coolant, lifetime ATF, or lifetime any other fluid! That's a lie, always has been, and I'm tired of pretending it isn't.

Have been part time rebuilding engines since the late 60's and have observed this on numerous occasions. Simple answer is possible, but seems no one will be able to find. Old tractors used to employ soft copper head gaskets, and you could have quite a bit of warpage and they would seal fine. Actually look at some old manuals, the head gasket could be reused over and over. All you had to do is anneal the gasket and throw it back in. Today the only way to get a copper gasket, is most likely for a old 2 stroke motorcycle. They were common on old Suzuki's. Your last chance is to find a sheet of copper the correct thickness, hand cut the holes, then anneal. Have had to do this several times, trust me you are going to have tremendous labor time, and then buying the copper sheet is very costly. They will seal with several thousands of warpage, but again is it worth the effort.

Angelo Panari owned Imported Motor Service on Hyde Street he came over to San Francisco because he was one of the Ferrari mechanics for Enzo Ferraries Formula cars, the Ferrari Dealership in San Francisco snatched Angelo up and hired him right up they brought his family over from Italy, they also gave him a apartment, car and he was givien a Green Card by the San Francisco Judge as the dealership guarnateed they were resonsible. I remember when he was working on one of Ferraries 12 cylinder blocks, he scrapped the crank shaft saddles using Prussin blue , he truely was a genius as he could lay his hands on the car and could tell in most cases what the problem was? Angelo passed away about 2 years ago he was wrenching till he died I was trained by the Italians some of the very best Italian mechanics in the world, NO JOKE!

I own a 06 Lexus (13 yrs) and a 1995 T100 (30 yrs now) . I have maintained them religiously! Coolant change, brake fluid change and 4k mileage oil changes. If something needs attention I fix it immediately. A few years back I was at a dealership talking to the service manager. He told me I was wasting my money changing oil so often. This video is music to my ears. It's reassuring to hear a master mechanic like CCN validate my thinking. Although I do not work on my vehicles anymore I still enjoy learning from this man.

[@GeneralElectricCNC]

I'm a Machinist and I feel your pain! I can see where the acidity of the coolant has degraded the coating on the head gasket. Why only on one side of the engine is a mystery. You need a granite surface plate to check the head for flatness, not just a straight edge. Use Dykem Hy-spot blue as it will give you a great image. You can also do the same thing to the block with a parallel bar. You can scrape the surface of the block in place to fix a slight low spot. It's tedious work, but better than removing and disassembling the engine! Some things are not easy, and this is one of them. Are the thicker head gaskets Toyota/Lexus parts or aftermarket like Cometic?

[@matthewbarrios1028]

My daily driver is a 2018 Buick Enclave Avenir AWD. It has 82k miles on it and has an extended warranty for 3 more years 43k miles. I took it to my mechanic, the dealer I bought it from and have proven themselves to be extremely trustworthy. I know the mechanic there that works on my cars personally. He called me and said, "hey! I saw your name on a service ticket that and wanted to tell you that we love owners like you in our shop." Then he said, "you're having all of the fluids replaced in the entire car!" He told me that my Buick looked and drove like brand new and spending the time or money to replace coolant, oil, transmission fluid, rear dif fluid, and brake fluid will make everything last wonderfully. He noticed that the front shocks were starting to leak just a tiny bit, which I asked them to check because I noticed it wasn't as smooth in the front lately and wanted them to inspect the control arm bushings, steering, and suspension. They quoted it to me, and I told them to take care of it. I thought my extended warranty was only a powertrain warranty. The service writer called me the next day asking for permission to call my warranty service. I asked him why and he said that I was wrong! My extended warranty is a bumper to bumper extended warranty!!! They called and got the approval to take care of the shocks for only my $100 deductible!!! These guys took it upon themselves to make sure I was right about my warranty and saved me over $2k because of doing more than I expected!!!

How often would you recommend changing coolant by years / miles?

[@tywal]

He said 50k miles or 5-years. That's still too long. I'm also a retired engineer and I replace coolant every 3-4 years or 30k miles. I do it every 2-years in my motorcycles. I don't care what the coolant maker or the car maker recommends. It's just not that expensive. Yes, there are autos out there that are extremely difficult to do a coolant change for a DIYer, and for those you should go to a reputable, capable shop. It'll cost what it costs, which is still a bunch less than a new engine. What's a few hundred dollars compared to $10k, $15k or $20k+ dollars. Just sayin... Auto engines are now very much a precision engineered and manufactured machine. Maintenance, regular maintenance, and more maintenance is super critical.

I put 770,000 miles on a 2012 4.6 Tundra doing oilfield type deliveries down here in Houston. I am vigilant with all of my fluids and was doing coolant drain and fills every 50k (miles) and transmission every 25k. The factory transmission died around 730.000 miles and I made the mistake by letting a small rebuilder rebuild it and it went back to his shop about 6 or 7 times. Had to sell the truck and was open and honest about transmission. I never had a head gasket failure but around 700k I started getting black buildup in expansion reservoir. I kept driving it all over the country and it never overheated on me. I'm not sure what was causing the buildup but possibly pinhole leak in head gasket. I'm currently on 220,000 on my 2nd 2014 4.6 Tundra. I really love the 4.6 engine and it works for me because I am not towing.

Hi AMD I totally respect all your mechanical abilities I love your videos. I have been a precision machinist and a mechanic for over 40 years you can precision lap that block and head very easily just get yourself a lapping plate. It is extremely easy you can lap off the high spots off both the block and the head and you will be amazed how easy it is and you will have no problem with the gasket sealing properly. Just get yourself a impregnated lapping plate so you do not have to worry about adding lapping compound. And with just a few swipes of the lapping plate you can knock off the high spots of both the block and the head you will be extremely happy. No machine shops needed. And you will not take off enough material to worry about the timing of the Engine. Trust me you are an excellent mechanic you can do this. You will save your customers a ton of money and also be doing fantastic work at the same time. One other thing the bigger the lapping plate the better but not so big that you can’t get it in the area where you need to lap the block.

[@jbeebo]

Yes this. If it's only 0.002" from flat it's minimal work to lap it true. I lapped the block on my 22re when I recently replaced the head gasket. Cast iron block, took a bit of elbow grease but helped me sleep at night.

[@littlet7556]

Very true. This doesn't need another block or block machining

[@theslimeylimey]

I have a similar background in machining and tool making and agree lapping would bring this engine back. I'd like to add that the amount of total "warpage" is less important than than the concentration of surface irregularity. A head or block with a gradual 0.002" bow in it will not be a problem because the head will flatten itself out to match the block no problem with little head bolt tension but a 0.002" hollow over an inch between the bores for example will not. I don't think people realize how floppy metal is when you start clamping it with bolts. I've measured the flexing of thick chunks of solid steel bending from only light clamping when the hold down clamps are only slightly off from being directly over the parallels underneath.

[@riverpirate1022]

[@jamesjobe927]

I second this! As a Subaru hobbyist I have hand surfaced the blocks for exactly this issue. The key for you is going to be time management. Get an aggressive block and a fine block to save time and still achieve the correct RA value.

[@harkness1833]

Great video! I’d add a piece of personal opinion: If you go back and look at those gaskets, they’re not JUST metal. They’re also coated in what’s referred to as an “encapsulant”. This is intended to fill the microscopic pores (grain) that exist natively in metals. An alternative example of this would be heat sink compound on a CPU. I have theorized that several manufacturers have been victims of a poor quality encapsulation on their gaskets. After all, these gaskets are usually made by others. I’ve seen these types of failures on multiple manufacturers and as the OP states, when it exists, there tends to be a pattern. I’d further speculate that a mild overheat could also be the cause of this. Some of the cheaper encapsulants start to break down quickly around 300F.

First sign of blown head gasket was misfiring on cyl #8 on cold start. I though it was a ignition coil or plugs. So i had replace all coils and plugs, but continue misfire but no over heat. even coolant level has not dropped. My mechanic told me that the head on 3ur engine cannot be resurfaced.

Coolant can become both acidic and begin to carry an electrical charge that will promote electrolysis. In a metal environment that has a current running through it (like an engine block), the differing metals are always trying to reach equilibrium at a molecular level. Galvanic corrosion. One metal will give up those atoms. As those atoms begin flowing through the coolant, the coolant increases its capacity to carry an electrical charge thus furthering galvanic corrosion. Flush that coolant folks. It’s cheap and you can do it at home. Be sure to burp the air pocket when the thermostat opens.

@@IH8Sn0wFal lost compression on two cylinders. Dropped borescope and there was bore scoring. I was experiencing gradual loss of coolant over time, misfire at cold start accompanied by white exhaust smoke. Interestingly once engine warmed up symptoms would clear up, I believe due to thermal expansion whatever gap was in the gasket would reseal and compression would go back up

Roll the dice. Replace the head gasket, overtorque by 3-5% and run it. Gaging warpage with a straight edge with feelers vs on a surface plate are 2 different animals. .001 over 20" is really small and compounding errors, straight edge tolerance and the feel of the gage leafs all needs to be considered. Head gasket construction and the material densities, even between manufacturers can be a crap shoot. Once upon a time, copper headgaskets and spray on copper particals were common. Your concerns over your reputation and liability are warranted. Great insight and ethics. Very refreshing.

The radiator cap and thermostat should be replaced at the same 5 year/50,000 mile interval.

How common is this problem really? The Tundra came out with the 5.7 V8 in 2007 and continued until 2021, about 14 years, and thus there are over 1 million Tundras sold with that engine that have never had this problem. There are even several Tundras with the 5.7 V8s that have gone over 1 million miles without this problem, and there are hundreds (or maybe thousands) of them that have 500k or more miles without this problem. Maybe it is a bad batch of head gaskets. I have been on the Tundra forums for years (a decade) and I have never seen or heard of this problem. If you add up all the other Toyota vehicles with this engine, and variations of it, it seems to be a very rare problem.

I think the real issue is people not checking their coolant enought. These trucks do develope common leaks like the water pump, radiator, and valley plate. If we are being honest most people do not check their vehicles on a regular basis. They just say, its a toyota, what can go wrong, before you know it the heads/block are warped and the head gasket doesn't seal anymore. Then they fill it up with coolant and take it to the mechanic and say, i don't know what happened, it just started misfiring all of sudden.

Machinist here, have you tried precision lapped stones on the face of the cylinder block? Not a stone, a diamond lapped stone. if that doesn't show you the high spot, lapping/grinding the cylinder block isn't a big deal for any reputable machine shops. They can measure it on their CMM or granite table and indicator and get a dimension before they grind/lap, then measure it again to give you the finished dimension and flatness. Either go with a tool and die shops, or aerospace shops. I would avoid automotive machine shops.

[@St0RM33]

I lap mine on 10mm float glass. It's the cheapest flat surface you can buy. Only to clean it up if already flat. If it's wrapped from overheating is gonna need machining with a flycutter.

Yeah for the kind of money here I would get the block machined to fix the 0.002" flatness, or just put a new head gasket in it. It is in spec.

[@erod6468]

The issue with this is that you can't just remove those 2 thousands(or more), plus any possible material off of the cylinder head and then just slap a thicker gasket. You may have compromised the very physical dimensions of the combustion chamber and valve train and will need to deal with that, as well as possible valve height problems and even requiring valve seat work, not to mention vvti issues and incorrect fuel ignition and compression due to the modified combustion chamber potentially causing a myriad of problems. I've seen more than a few vehicles that were brought in the shop in my many years as a tech after major repairs and machine shop work, misfiring and with ses lights on only for their respective owners to be told that they need a new engine due to deck height measurements being out of spec due to machining. These high tolerance engines along with their respective supporting systems do not allow you to get away with much. These are not the same engines from yesterday.

I listened to this a second time to make sure I understood the important point. He said the measured warpage is 0.0021. The specification is 0.00257. The block is within factory specifications. He is justified to install a new head gasket on this engine. As he said, there is some risk. He needs to talk with the customer and explain the situation and ask the customer if he wants to take a $5,000 risk on a new head gasket where Toyota says it is within tolerance. I suspect he did just that with his customer. He may want to consider making a cleaning cut on the head to make it perfectly flat. This will eliminate the possibility of additive warpage of both head and block throwing the total warpage out of tolerance resulting in another head gasket leak. This guy is a perfectionist and is the best.

[@chrisklein9144]

The block is within specification, I would expect that Toyota engineers know that the gasket can accommodate the warp up to the point on the specification the block may have had the existing warp at the time of manufacture. It pasted 190k. I would not be afraid of doing the job. Closely inspect the head as you suggest is a good idea. Of low at the failure point grind it flat.

[@bobblack3870]

@robertjohnson4401 I think you missed a couple of points. One, his experience has educated him that a new gasket will NOT result in a "good as new" result, even though the block is within spec, so he felt obligated to inform the customer, allowing the customer to make an informed decision. Two, he will not touch the block to flatten it because of potential damage, which he explained - again, a risky move.

[@robertjohnson4401]

@@bobblack3870 I did not miss either of your two points. I agree he should not touch the block. I said he could see if the head flatness could be improved to improve the outcome.

The customer can make the decision.

Recently I purchased a high mileage 2014 Corolla (156,000 mi) and it seemed to have a head gasket problem. As it turned out ( I4 2AR) cylinder number 2 was "steam" cleaned just as your video shows for cylinder 7 on V8 UR. The steel gasket also shows the same "signs" of some kind of coolant "migration" into cylinder #2. In my case the head and block checked out OK as far as I could measure but I just didn't like the idea of putting time into fixing with the same type of steel gasket if I couldn't fix it for "good". Contrary to your "don't use a Felpro gasket" in July I did just that. So far at about 6,000 miles all is good. It took me an investment of 28 hours of my time and about $200 for all the items needed to do the job. I really respect you as a person as I can see that you really think about the customer and their situation. No doubt you will be seeing an increasing number of these. I intellectually love how you honestly looked at the costs and pathways of doing it "right" for the customer, you sir are a real "GEM". Thanks for making this type of video, superb! Like you say, the cost to repair is "more than the car is worth" is totally accurate to provide the perfect repair in an imperfect world. I think that ( as an engineering technologist ) the space between the cylinders is too small and perhaps the coolant passages should be "rethought". My dad was a certified machinist and in his day he would do his utmost to make the repair "as good as it gets" but his skill and tools were only so good for the 1960's. I was always amazed at what he would come up with, get away with, at such a low cost and that actually worked for years and years. But when dealing with customers, understanding is KEY. So we shall let the "real world" decide if my head gasket repair will allow me to continue with the Corolla for another 10 years of life, I expect it will not be "clear cut". 🙏😃

IRL the RC F transmission can handle track abuse without overheating due to cooling radiators, plus it shifts lighting fast when you use S+ and Manual mode, dude did not even drive the car and trashed it. Again he is not an engineer. LC500 transmission is digi shifter plus too heavy for RC F chassis so it wont fit. Lexus will have to develop an entire new Carbon Fiber monocoque to handle that heavy brick. And why would they do that, when they already did LFA with Transaxle 1LR V10. It will cost them a ton of money. Toyota won't listen to anyone except their pockets, the company was in downward spiral ever since they discarded their motto of Lexus's "In the pursuit of perfection"

[@chrisharper2658]

I can see a real need for an LS swap kit for those big Toyotas. Just think how much easier they would be to work on and maintain.

[@warriorplutotrent3827]

I was thinking the same thing. A swap like that would make sense. A reliable 6.2 or cammed 5.3 with ported heads

[@cliffordcullen1687]

Stuck a LS3 EROD in my 1990 FJ62. Thing is a monster 👍

[@jdrex02]

Long time Toyota technician here. I have only seen one of these engines with the head gasket leaking coolant into a cylinder, except it was on the opposite bank on the #8 cylinder. So I thought I would let you know that it does happen on bank 2 as well.

[@Barbarapape]

Even Toyota's can blow a gasket. At 200k miles a lot of other cars are not worth saving, but Landcrusers are capable of spaceship milages.

[@rightlanehog3151]

Exactly. A fellow in Louisiana will soon be hitting the 1 million mile mark with his Tundra 5.7 V8.

[@edriley1516]

.....guess you didn't see the part where he said $23,000 fix.

[@Barbarapape]

@@edriley1516 Compared to the price of a new Landcruiser, it may seen a lot to pay but better than buying a load of trouble.

[@henrymiecz8566]

Spaceship milages? Is that after or before the BLOWN HEAD GASKET/NEW ENGINE!

[@mad-meh2719]

Did you not watch the whole video😂

[@elora2525]

I'm a BMW technician most "blown head gaskets" we get is usually consequential to an overheating . We call them "baked" engines we really don't repair them it needs a long block. Once we get them torn apart we find more anomalies besides a warped block everything is compromised from sleeves extract, oil starvation to bearings, scored cylinders, cracked blocked behind the sleeves( lately those are absolute), head threads that pull out when torquing etc etc

[@paulsolovyovsky1702]

hmm..the smell of N63 engines with valve seal leaks and head gasket crapping out as well as everything else going to crap..the memories of a quart every 200 miles..this is why I bought the LC500 next

[@mph5896]

Yup, that is truth with just about every modern auto engine. Overheat it, blow a head gasket, best to junk the engine. That coolant leak somebody kept topping off, and then overheated it 🤣They should have spent $500 on the new radiator.

[@moreblessingncube6877]

Everytime I watch your stuff, i learn something. I'm just blown away by your honest and work ethics, it's unbelievable.

[@JC-yt1pm]

When you talked about coolant it was the first thing on my mind. I do not know if dealers are the problem or Toyota is the problem. I have to argue with my dealer to change the oil at 5K not 10k. I see a noticeable difference in MPG and engine noise reduction between the two.

[@edriley1516]

anyone that chages their oil after 5K miles is a fool. i never go past 3500 with anything. engine oil and filter way cheaper and easier and will help with longevity and reliability.

[@randywl8925]

If you change oil like they say at 10,000 miles, they'll be selling you a new truck sooner. The engine only needs to outlive it's warranty period. ........they absolutely have that figured into the equation. Oil is cheap.

[@NVRAMboi]

Keep arguing. You're in the right. Even more, YOU are paying the invoices. :o)

[@tardeliesmagic]

Agree...5k. Just change the coolant 5yrs/50,000m max! I had a 2002 Yaris 1.3L 4sp auto here in the UK for nearly 13yrs (66,000m when i got it & 99,000m when i sold it....has 104,000m as of today) & i changed the coolant every 4yrs with Prestone,changed it 3 times in my time. 1st flush was with deionised water to get any old coolant out properly. My old Yaris has never had the head off/head gasket issue,water pump or even a new thermostat....it was 6yrs old when i purchased it (2008) ,it hasn't even had a thermostat in those early 6 yrs either! Sold the car on 3 yrs ago to someone who i still talk to & still no water pump,thermostat/head gasket replaced. Regular oil changes every year 4,000m with Castrol Magnatec & it's still purring like a kitten today,emissions is still brilliant as it's real strict here . Problem was when i sold it the road tax was £185 a year it was £175 a year prior, just typical UK greedy government wants us out of old cars. As of today it's £255 . My new 2015 Yaris 1.3L CVT is only £30 a year (prior year was £25). Fuel consumption of old Yaris was BEST 48mpg & new Yaris 58mpg. I did make a good move getting a newer Yaris. Just DON'T believe what it says on the coolant.

[@hhjhj393]

I keep looking at used cars and I will check the carfax and see all these 10k-12k oil change intervals and it makes me cringe.

[@ejesoriginal]

Welp. Last week I did a 60k / 5y service on my 2020 Tundra. Now I know this week I'm doing a coolant drain and fill. I always thought it was strange the manual suggests 100k for the 1st coolant service and then 50k after that. Thanks for the alert and video!

[@jeffwilliams8277]

That is because they know you can't get all the old coolant out. So the new coolant is diluted.

[@ejesoriginal]

@@jeffwilliams8277 that probably makes sense...to them. It should be every 50K from the get-go, but then they couldn't sell their "extra long life" coolant now, could they? That extra 50k means you are just diluting even more acidic liquid by volume instead of less acidic if you do it earlier. It isn't as though their coolant costs what their ridiculously priced "magic unicorn and gnome tears" transfer case fluid does (which I never use). This crap of less maintenance is just cutting corners and pie in the sky salesmanship by these companies. Sealed transmissions, no dipsticks, 10,000 mile oil changes with ultra thin oils, no grease zerks; all poo-pooed and argued by saying fluid technology has come so far you don't need to worry and it helps save the environment. It all adds up to what they hope to make "throw away" cars that are more and more expensive. Total BS.

[@alexclusivity.]

Ex-Lexus tech here. Make sure to drain the coolant from the englne as well!!! Most engines (idk about the newer ones) usually have a block drain which helps drain even more coolant from the system, obviously not all, but the majority for the most part. Just try to drain out as much as you can so you get the best results. Really wouldn't hurt to also add some of the coolant additives from BG (Super Cool) or Amsoil (Dominator Coolant Boost) as they actually do help with keeping the integrity of the coolant for longer and higher temperatures as well, which is vital.

[@pshaswat]

That’s why I got 05 100 series. Very happy with it. It clocked 175k. I am taking to you next month for checkup.

[@tom8836]

Great video. I love the content but you raised some good points. I own the same GX460 as you and have followed the maintenance schedule for the first year in addition to an oil change at 1k and 5k. Can you make a video on preventative maintenance that you would do on your own vehicle vs what the manufacturer says to get ahead of messes like the one affecting this land cruiser? Lexus isnt recommending oil changes at a normal interval, they arent really covering greasing the propeller Shaft, Spiders, Slide Yoke, Zerks to name a few tihngs. Im sure it would be referenced for years to come.

[@mdenos1025]

Agree bought the same GX. Done your recommended oil changes. Give me a spreadsheet or video - I’ll do whatever you recommend. I bought this expecting 250k to 500k out of it and I will take care of it to get that.

[@freddyhollingsworth5945]

That's crazy. I'll keep my 4.6 Ford V8 with 470,000 miles and no issues, original head gaskets, and all, still runs like new....

[@christopherclark4774]

@@majist0 as a 2uz owner, the 4.6 ford mod is like a 2uz for people who dont maintain and abuse their cars. Ran the company work van low on oil and it was ticking about 2 years ago. Bottle of marvel mystery oil and top off with a random quart of lawn mower 10w40 oil and the thing is still running. No timing belt so it never had to be maintained.

[@BIGGIEDEVIL]

I get what you mean but do a compression test and see if it’s like new the fact you got that much mileage is incredible new cars won’t see half that ever

[@bradenriley9066]

​@@HarrisonFjord-n3vI doubt that. Working at a Ford dealership in the early 2000s, I saw many, many 4.6 2V with over 500k running in taxis. Those taxis Idled all day and were abused. 4.6 2V has many engine awards. And you don't have to worry about rust like you do with Japanese trucks.

[@goharhayat2489]

A family member had the same issue with a land cruiser he purchased on 150k miles . I was surprised but true. 😮 Assumably the previous owner may have been somewhat lackadaisical regarding maintainence but who knows. He chose not to fix it realising it would cost thousands. He sold it for parts and bought a land cruiser turbo diesel which is still going strong. Based on your in depth video he's one of many to have this experience. Thanks for highlighting the issue and emphasising the preventative measures.

[@christine21068]

Now you've got me really worried! I've got a 2013 460 GX with almost 160K mikes on it. What should I do? Get rid of it now?

[@Fabianto-san]

we had that kind of problems with most modern all-aluminium engines. Luckily I live in a country where nobody cares about emission regulations so I just delete the catalytic converter, replace radiator cap with a lower pressure one and put thicker oil 😉
