    Im just wondering. If it was concluded that there was no evidence it was the electronic throttle, why did toyota settle by paying 1/3 of a years profits?

    why the recalls?

    why were other vehicle manufacturers not included in the lawsuit?

    after reading a little more up on it. It sounds like a settlement was agreed upon to stop the inquiries into the numerous deaths. And to pay out the families.

    I don't know, you could present some evidence and tell me perhaps? You realize that a civil or criminal court is not the same as an independent group of engineers who aren't being swayed as much by emotion right? How many of even the largest corporations can sustain a fight against the U.S. federal government? Does the U.S. Department of Justice only prosecute guilty people or does politics get in the way sometimes? You could always ask Gibson Guitar about getting raided. Settlements are paid out all the time for various reasons.

    Or, because none of this has anything to do with the 5.7 engine, you could take it to PMs?

    I'll add one more to the catastrophic engine failure club. My 2013 tundra broke a spring and dropped a valve last week. 160k km. Out of warranty. No SC, no abuse. Currently feverishly searching for an affordable engine. Looking like 10-13k can$ installed for a reman. Loved the truck until this. Friend with a machine shop is gonna take a look at the potential to rebuild too but I'm not optimistic. If your lucky you can likely buy a tundra without worries like this. I'll probably never own one that's not covered by warranty again. Once I get past this one. If anyone's got a line on a solid salvage let me know.

    Man, that there's one heck of an intro post. Sorry for this happening to you. Welcome from Texas Hill Country. :(

    There's still hope until he bore scopes the damage. Dependent on luck and how quickly you stopped the grinding. :fingerscrossed:

    So why a New or replacement engine for a mere dropped valve? Not a rebuild, just a repair....

    There are a couple reasons depending on how far/deep the valve dropped. If the piston hit it with force, then you need to measure the con rod, need to inspect the piston for cracks and it usually breaks a lip off the valve which then bounces around scratching the hell out of the walls. All which require a full teardown, which can then easily be more than a reman motor. I have seen 5.7s break a spring and not drop a valve, which is then a good repair. But usually the whole cylinder is screwed. So it all depends on what they find.

    Sucks to hear of yet another serious engine failure. Hope you can get it fixed or replaced for much less than you’ve been quoted. Please keep us updated.

    The anti Ford bias around here is reaching pandemic levels. Some people are just pissed that Toyota is just now catching up in technology to Ford from 5-10 years ago.

    Yeah that was kind of a troll, but really the emotional "arrrghhh blue oval baaaaaad" mantra is getting old. It's like someone buys a Toyota for $40k and somehow ends up with a chip on their shoulder because it isn't a Ford. Almost as bad as the the Cummins 12v guys and their constant Tom cruise syndrome. Or the 6.0 powerstroke guys that just have to prove how great that engine really is.

    Facts=good
    Cults=bad

    IMO everyone wants to take their own personal experience or even the experience of people on these forms and extrapolate that out to make generalizations. The problem is our experience isn’t generalizable. There are actuaries working for banks/leasing companies who predict residual values of vehicles, trucks included. This isn’t based on opinion, it’s based on profit. Banks like Ally need to know how much each truck they lease will be worth after XX months and XXXXX miles. When you look at lease rates, Tundras hold their value the best as evidenced by their residual values being consistently higher resulting in lower lease payments. The other objective and large sample size decision made by actuaries are the prices charged for OEM extended warranties. Toyota extended warranties are less expensive than other companies, especially their trucks. This doesn’t mean there won’t be failures, and individuals here have obviously showed us that the 5.7 isn’t perfect, like anything mechanical, it has a failure rate. But the failure rate of the 5.7 is lower than the failure rate of the Ford 3.5. 5.0 or TM 5.3 or 6.2, etc. That’s not hating on Ford or GM or Ram, and there will be individual trucks from all the manufacturers that are great and trouble free (in fact, most are good trucks, we hear a lot of nightmares on Internet forums). But, statistically, if you want to minimize the chance of break downs and maximize the chances of long-term trouble free durability, your best bet is to buy a Tundra. But there’s more to consumer decisions than pure data, and plenty of room on the market for all the auto makers to put out products. Educated consumers value different things: IMO Ram has the nicest interior; Ford has the next nicest; and then GM. The Tundra interior is dated. The safety ratings of the big 3 are demonstrably better than the Tundra per NTHSA. I bought my 2017 CM Limited for the huge back seat, reliability and durability... which are all demonstrably better than the Big 3. The price I paid and resale value of the Tundra are far better than the Big 3. Also not up for debate. I think the folks that own Tundras are lots better at laying out the facts and talking about the strengths and weaknesses of the different brands. But at the end of the day, caveat emptor. Know what you’re buying and don’t take it personally when someone else made different choices. Enjoy your Ford or Chevy or Ram. You paid for it. I’ll enjoy my Tundra. I paid for it. Great to have choices.

    Not sure if this has been posted before, but here's an interesting video from July 2019 that talks about the content creator's buddy's Tundra 5.7L that blew a rod and punched a hole in the block at only 52K miles:

    https://www.youtube.com/watch?v=qKAX-iqXTc4

    So although these blown 5.7's appear to be rare, they still occur nonetheless.

    The 5.0 has oil consumption problems very bad. And i know yours is 2017 but in 2018 over like 10 recalls for the f150. Their quality went down the shiter big time. My buddy has the f150 2.7 eco and got stuck on the side of the road because his turbo sensor literally blew up only like 15,000 miles on it. Im not at all a fan boy of toyota im just listing facts and whats happen in real world events.

    I had an ‘86 and a ‘93 fullsize Ford Bronco. Both had the older 5.0L V8. Despite everything else on those trucks breaking down (3 transmissions, e-transfer case, power window motors, a/c (numerous times), starters and numerous starter solenoids, neither engine ever gave me trouble. I was always shocked when it would pass the annual emissions, too, considering their age. I had a love/hate relationship with those Broncos. They were great when they would run right, but they often broke down and would leave me stranded a few times.

    I haven’t kept up with Ford’s truck lineup the past decade or so. Does Ford offer any other truck engines that are proven to be reliable and trouble-free?

    As for Toyota, I became a fan when I got my first Toyota 4x4, a ‘92 4Runner. It suffered from the infamous 3.0L V6 headgasket, though. Those engines were slow dogs prone to blowing gaskets, but at least they weren’t known for stranding you or outright blowing a rod through the engine block. The rest of that 4Runner was built like a tank.

    And my stepmother’s two year old Toyota Highlander’s engine failed completely and left her stranded on the road last year. Luckily it was under warranty. Have no idea what happened, though.

    I had 1995 f150 5.0 blew 3 engines in 3 years not a fan of that design leak oil everywhere and electric issues out the ass. Now i should not say ford i should say f150 in general has the least resale valve and the least reliability and durability from the consumer reports. Why would anybody buy a vehicle at 50,000 plus breakdown on you within 5 years and get tired of it and sell it for half the price dosent make sense. Now i know f150 is the number 1 sale truck in America and people will have more issues with them because theirs more of them. But at the end of the day its what you could afford at that time. To me i love the raptor could i afford it hell no. So i brought a 10 year old tundra that will last me another 10 years. And than i could buy gen 4 tundra..

    No, actually it's the F series in general. There's a lot of truck configurations possible so hence the high production numbers. Also I don't think the sales figures would be so high if Ford didn't have all the fleet and municipalities buying them. Buyers get a lot of deep discounts that way. If Ford relied on the general public for sales, I doubt the numbers would be as good.
    I ended up with a used 94 F150 4X4 10 years ago because Fords were cheaper than anything else. I learned why they're cheaper the hard way. Otherwise it's still a good yard truck.

    Beat me to it. I was going to mention the same thing happening to Audi back in the 80's I think. They were eventually cleared, but it didn't get any press once the truth was available.

    Domestics were struggling for sales so the guvment stepped in and turned their biggest competition into a safety hazard.

    I hope your right. I'm not a mechanic though so I have very little knowledge of what it actually takes to destroy the engine. But the mechanic was fairly confident that this was looking like engine replacement would be about the same cost as an engine rebuild. I may have a more economical line on machining then he would have gotten me now though.... so well see.

    But to explain the extent of the damage more, if it helps, it appears as if the spring broke, the valve fell a fair ways in as it was bent or broke in half and is stuck to the head. Spark plug was smashed up. So I am not confident that there wont be damage to the cylinder walls and piston, and the head must definately have damage.

    I've never paid for engine machining. So I have no idea what sort of cost I'm looking at. But I think that if I have to machine one cylinder I probably have to machine them all right? All new pistons?

    Yep. I personally wouldn't buy a Ford truck but if they were as horrible as this forum claimed they simply wouldn't sell that many trucks.

    I've posted this several times but my brother just retired his 2000 F-150 with 300k miles. And he's not one to keep up with all the maintenance. He only changed the transmission fluid once in 20 years...

    I have an '01 Crown Victoria with over 223K miles with a 4.6L which may may be similar to what was in your brother's truck. It's still going strong on all it's original drive-train. Not everything Ford makes is that bad. Why else did taxi companies and police departments like this car so much. Maybe they designed the Crown Vic's better than their F series trucks.

    My father-in-law’s ‘97 F150 has almost 400K miles on it. It’s been rock solid and has never broken down on him or given him any trouble. Just regular wear and tear maintenance (oil change, battery, brakes, etc.). He’s never changed the trans fluid, either.

    He also had a single cab F150 with the inline 6 and manual trans that went 600K mostly trouble-free miles on it before he had the engine rebuilt! He reluctantly sold it, and it’s still being driven around town.

    Ford can come out with some reliable, trouble-free non-lemons sometimes, but it seems they’re more hit and miss and less consistent than Toyota when it comes to reliability. As noted in this thread, though, Toyota isn’t immune to pushing out some bad eggs every once in awhile. It just seems that happens less often, but it could also be that the Tundra’s sales volumes are so comparatively low it just appears that way.

    I think the AIP system in the Tundras is a pretty bad egg that seems to be plaguing a lot of owners. There's plenty to read about it in this forum. It's not an inexpensive repair and some owners have been lucky to get Toyota to pay for it. To me it's a ticking time bomb waiting to happen. My truck has already had it repaired twice by the previous owner. It's only time that it will happen to me. That is a big reliability issue. The failure causes the truck to go in limp mode and clearing the code is only a temporary fix. There are bypass fixes available but that does not truly address a serious flaw in that system. It will probably keep failing over and over.
    When it comes to buying any truck these days, it's all a matter of choosing the lesser evil. I've owned trucks from the big 3 and even some Nissans/Datsuns too. They all had their good points and bad. I like my Tundra but it's far from perfect. Only time will tell how good my ownership experience with it will be.

    How is it possible to know the valve "was bent or broke in half and is stuck to the head", and not know if the cylinder wall is damaged? :confused:

    It will be very important to make a good assessment of the damage without any tear down. If the affected cylinder wall requires machining to clean up, then you are looking at a total rebuild. All cylinders will require overboring to the next standard piston size with replacement of all the pistons ($$$$). If you can determine with a bore scope that the cylinder wall is going to require machining, then you should shut down the cylinder rebuild and opt for engine replacement IMO. Your tech said engine rebuild would be about the same money as engine replacement; I would believe that to be true for a Toyota reman engine (a better option than rebuild imo), but maybe cheaper if you can find a low mileage salvage engine.
