Tundra engine recall - interesting news

I suppose it possible. Seems unlikely that there will be a need for 100,000 "good will" engines over the lifetime of this motor. But as has been stated before, none of us know and will probably never know. It's also possible that Toyota has determined they can't be re-manufactured and that's why they want them back.

 

Bingo. It's a AMC 360.

A little known fact was AMC used the same exterior block design for all 3 displacements. The bores and internal parts were basically the only differences. That made swapping out a 304 to either a 360 or 401 a bolt-on plug and play project in '80s AMC cars and Jeeps.

After building it, I stuck that 360 in my 1981 CJ7. It's a lot of fun to drive.

 

Sure, that’s a theory.

Let us know when you have some evidence for the claim that Toyota is going to re-use anything shipped back to them.

 

They’ll be the long blocks that replace all the upcoming blown engines for the next decade.

 

It was part of the memo that went to dealers.

 

They’ll be the engines used when they finally recall the hybrids.

 

It's a good theory but the safety recall specifically says "new". Definitely trying not to argue one way or the other and so far I'm not in the recall with my 06/23 build but I find it very hard to believe that Toyota would risk extending this debacle by using a re-manufactured engine.

 

Hows about this for an explanation...I mean theory/speculation:
The insufficient cleaning (deburring and subsequent cleaning actually) was the trigger, and the design flaw(s) the gun.
Were it not for the lax cleaning process, the subsequent failures may not have presented themselves in any quantity that would have gone beyond statistically insignificant.
We'll never know.

Still means the initial design is root cause though.
And if that's the case, I don't see Toyota owning it any time soon. Corporations are not Samurai, regardless of country of origin.
I'm just glad they're putting new engines out there and not completely sweeping it under the proverbial rug. (I know, not possible with a safety related recall, but you know what I'm saying.)

I'm out before @Breathing Borla jumps in here and says all we're doing is just mental masturbation (which it is) anyway.

 

I did not see that memo…?? Who at the dealership received them?

 

That’s true re: new. But once the recall is completed, and assuming there will be more failures in the hybrids, the unrecalled 2023s, 2024s and 2025s. And possibly they’re assuming the recalled 2022s and 2023s may be coming back in after they’ve gotten their first long block replacement for another at some point and they’re getting ahead of the demand. Not insisting I’m right either, but the theory just seems to check a lot of boxes.

 

Post it, please.

 

Would this not only be the case if the design flaw was that the engine could not tolerate machining debris? Which I believe holds true for most engines.

 

Value of parts on the engines that get reused for cores/remans alone likely justifies returning the engines to Toyota. High pressure fuel pumps, fuel injectors, turbochargers, etc.. Add in the scrap value on other parts…

 

That hasn’t caused any issues on the forum…


Let’s ask Ryan Gregg

 

But the current recall isn’t including the Hybrids so that doesn’t apply to them - right?

 

True. But I still believe Toyota won't risk using remaned stuff for anything including recalls, warranty, or good will. I'm glad to be proven incorrect.

Maybe @Raven67 knows if Toyota has used remaned engines in the past since he worked for them? Just curious ..

 

You guys that have built motors and know more than us mere mortals who only know how to put gas in the tank, you own a Gen 3, out of warranty, motor blows up, and you are going to rebuild it. What would you do different, if anything than Toyota is doing? Build us a better V35A.

More into bikes than trucks, truck is just a way to haul our bikes and trailer around. Never owned a harley but found it interesting how S&S handled things like blow by vs harley's own design, always seemed like some better engineering.

Just because Toyota spends millions on R&D doesn't necessarily mean it's the best or only way to do something. Honda build very over engineered bikes but can be difficult to work on, Kawasaki build well engineered bikes but also made to work on. Honda engineered by engineers, Kawasaki built by engineers who ride. There's a difference.

Were decisions made in the design / production of the V35A to simplify manufacture, save money? That are now coming back to bite Toyota?

 

machining debris got in some of them, those are being replaced

 

I have no idea, I worked at a manufacturing plant, nothing was rebuilt or reused there. For new vehicles only. Any defective engines or parts we got back were checked & scrapped.

 

Well for starters the V35A-FTS cylinder block is non serviceable so there’s no rebuilding one unless you can convince Darton to make cylinder sleeves and fully sleeve the whole thing. Which is going to cost more than buying a new short block.

To answer your question, if I were king of Toyota I would have ditched the V6 architecture completely. Then I would take the stout I3 in the GR Corolla/GR Yaris or the I4 T24A-FTS and made an I6 on either of those two architectures. Then you end up with more main bearing caps, only one cylinder head, simplified turbocharger and intercooler plumbing, and only one intake air box. You also get inherent primary balance in the rotating assembly, and I6’s just seem to produce a naturally wider torque curve. V6’s suck compared to a good inline 6. With turbo 4’s in every other space constrained engine bay making better than old naturally aspirated V6 power the V6 is no longer needed.

 

Guess Toyota should have asked Volvo.

 

The straight 6 in our Supra TT was o so buttery smooth , way more than the v35

 

Str8sixTT

Dats me, had a 89 mk3 supra, always wanted a mk4 suprA

 

What a machine

we had several as the old man worked for Toyota for a long time

we also had the 15 year anniversary one in red , manual transmission, what a machine unreal ,

blew by my buddy in his typhoon on the interstate at 150 lol. Not the smartest thing but damn that thing was smooth at 100+

100 felt like 55 in most cars at the time

miss those cars but miss him even more

 

I'd love to have a Typhoon, Syclone, or GNX. Not picky, any of them.

 

Out of those 3 hands down a GNX

 

Buick made a badask V6 that could take some boost. I had an 87 Regal T that ran 10.81 in the quarter mile with a weak watergate actuator that let lose at 19 lbs boost. That was the small original motor. I ended up building a steel stroked motor with a much bigger turbo that could hold well over 35 lbs boost. Not that I ever got it there. At 18 lbs on a 60mph roll, it didn’t only break the rear tires loose - it would get sideways. I had to sell it, or it would have killed me. I like to feel power, and it was all or nothing. It would go from 250hp to 680-700hp in 1 1/2 seconds and very violently.

Look up on YouTube 10 second Buick daily driver. That was my first run in the 10’s. I had a fully stock suspension and it launched hard and awkwardly. And that was the small motor combo.

Here’s the car

 

Just simply badass!

 

Had an 86 Olds Cutlass Supreme that looked just like that, but without the badass motor. Supra was the car of my dreams but unfortunately never got the chance to own one. You guys were lucky.

 

Nope, they are Toyota, guys, not TUNDRA guys,
Are they the ones who developed the Tundra? Are they the ones who built faulty motors for tundras in japan? nope they are not the ones who built them in the US? are they the ones who assembled tundras in the US? Nope, Tundra was developed, built and assembled by US samurais (rednecks) LOL....Under the name Toyota.
