The video every 3rd gen owner wanted.

Interesting, yes.
Anything definitive relating to the recall? No.
He stated at one point the "event" that took the engine out was due to oil starvation.

What I really want to see is a comparison of "before bearing change" bearings and "post bearing change" bearings to see any physical differences, if any.

 

Of course they looked better.
Did your 360 with unknown mileage suffer a failure due to oil starvation?

 

yes, this ^^^^

 

Now if we saw the internals of a 100K+ mile engine that had lived a normal life with proper maintenance with no catastrophic failure and we saw wear like that, different story.

 

What I would like to see it a pull down of a recall engine and a non-recall engine. However i doubt that will happen

 

Yes.

Stories like these all over the internet: there are god designs and bad designs. The Pentastar has other issues related to some cheap internals, but the bearings, crank, etc all speak for themselves. Something is amiss with the 3.4TT.

Fair point. Without knowing what caused the oil starvation, there really isn't any conclusions we can draw from this video, IMO.

Too bad this guy can't get his hands on a well running engine that's been swapped for a new long block. I'm sure the visible wear would look a lot different.

 

I agree the design has been around but never with 500 lbs of torque. I agree with your thinking.

 

Exactly. An aluminum girdle with steel caps built in, then torqued insanely tight and inconsistently, can't offer consistent bearing tolerances in my mind.

I'm sure there's a reason the engineers chose the girdle design, though.

 

Engineers or bean counters?

 

how do you know they were torqued from the factory insanely tight and inconsistent?

I bet it was the opposite of that as far as consistency

remember this thing is not a factory running motor , so the data is junk

 

2022: Its just a normal failure rate, nothing to worry about. There’s nothing wrong. Shut up.

2023: It’s a production issue related to a few malcontents in Alabama. In fact, it’s some Toyota hating red necks working there that are responsible. There have been no failures from the factory in Japan! American workers suck! Pfft!

2023: it’s a machining debris issue that effects motors made at both plants, it’s still probably those red necks in Alabama tho and only impacted a few motors, but whatever the problem at the plant has been fixed now so shut up. Plus, 2nd gen owners give me such an inferiority complex, I’m gonna start blaming them for talking about this “NON ISSUE” in MY truck!

2024: OK, Toyota issued a recall. Fine. Maybe it’s real but maybe it’s not real. But see how much better Toyota is than every other manufacturer? Toyota has identified and fixed the issue on the line and now they’re giving all owners a new long block. Well except for hybrid owners, they only get short blocks. And the 12 month/12K warranty on the new long blocks kinda blows. But it’s irrelevant going forwards because this issue has been fixed. There won’t be any more failures from here on out. Just shut up already 2nd gen owners. In fact, why are you guys here at all? Go back to your own side of the tracks, these discussions aren’t for you!

2024: internet trolls are continuing to report failures. RAGE! We know these are made up stories because the people only posted the VIN numbers and pictures of their trucks on flatbeds. Seesh. Show me some proof guys. Plus, Toyota said they fixed the problem again because the first fix of cleaning the debris didn’t work. But it’s for reals fixed now so shut up.

2024: Failures reported in 2023, 2024 and early 2025 trucks online aren’t real, in fact, it’s just the same 3 failures being reported over and over again. Where’s the PROOF? You can’t believe anything you read or see on the interwebs anyway. There’s no problem with this motor. Plus, Toyota just fixed the cleaning on the line for reals for the third time. Even if there was an issue it’s been fixed 3 times already and Toyota told us so, which is plenty of proof for me.

2025: um, well, I mean some random guy on the webs says that motors made though the 2025 model year are still
failing from the “debris issue.” I know that’s not true tho, because Toyota said that the problem on the pesky lines, in BOTH factories, was *really* fixed again in late 2024. Why are we even talking about this. Go back to your own forums. Toyota said the production problem has been fixed for the 4th time now, and it’s 2025, didn’t you know it’s the 4th time that’s the charm? Jeez. Why are you 2nd gen guys such skeptics anyway? Toyota said the assembly process has been fixed for the 4th time at both factories, and if you don’t believe them, you’re just trolls. RAGE! Go away!

2026 or 2027: …… the redesign? The return of the V8? The new chicken tax Tariffs end all light duty foreign truck sales in the USA?

At some point, you have to lean towards the explanation that makes the most sense. If it was a simple cleaning issue on the line, it would have been fixed the 1st or 2nd or 3rd time. There’s too much money at stake in repairs and recalls to not fix a manufacturing issue IMO.

 

Did you not see him have to resort to a 5' breaker bar to remove the girdle bolts? I think he even had to cut one of them.

I've seen excessive heat loosen bolts, but never seen it make them tighter. So, I'm assuming they were torqued that tight at the factory.

 

ok

guess we need a non failure motor to see , let’s take apart yours , I’ll buy the beer ! Ha

 

Do you feel better now? Hope so.

 

no he doesn’t , I’ll give him one thing he’s consistent and committed lol

maybe we should just sell all our perfectly fine trucks and buy older ones and make him happy

 

The pcv valve location looks like its in a real inconvenient spot. I wonder if it could pull a tacoma and suck up oil on a steep incline like the 3.5 has been reported to do?

 

Aka I can’t give quantitative info, so I need to throw out my own perception that lacks any substantive information. Then try to back it up with the chicken tax, which is hilarious you think that. This is also know at an internet troll or a 5 year old argument, get a juice box and calm down.

 

And here's what it always come back to. On both sides, really.
What I'VE seen and experienced:--> Assumptions.
That's all we're doing.

I've seen catastrophic engine failures do some extremely bizarre shit. Like, how in the hell is that possible? Well, it's possible.
The majority of the wear and the crazy tightness of the girdle bolts (some, not all) could have all happened in the last minute, or seconds, of that engine's life.
See? More speculation.

 

Yes, it’s the tyranny of the truth. My arguments about this motor haven’t changed because the facts haven’t changed. Once the failures stop, then all we will have to talk about are minor annoyances like radio knobs and seat plastics, which I are flaws I can deal with. And you’re right, the 3rd gen truck is mostly fine, it’s the motor that’s the problem. Once Toyota sorts the issue with the 3.4TTout, I’m probably a buyer. But it totally depends what happens with the chicken tax.

 

If it wasn't for speculation and relating our own experiences, what the hell would we talk about? I guess there's always oil threads. Those are fun.

Speaking of bizarre shit. I had a pushrod blow thru a brand new rocker arm shortly after rebuilding this engine. The pushrod, lifter, valve and camshaft were undamaged. I just replaced the rocker, and the engine has purred like a kitten for 13 years.

 

Agree. There were some pics of Ryan’s motor and the parts you could see looked spotless.

 

Which eliminated any fears of that new aluminum cradle/girdle design for me. It’s only there to speed up assembly. After those 4 bolt mains are cranked down that tight that aluminum cradle/girdle is doing nothing as far as supporting the mains.

 

Found It. I saved one

 

Odd nobody is concerned with all the carbon around the valves? Even if the motor had 100k miles on it, those valves for a modern motor are pretty crusty.

 

Crappy fuel quality? Short heat cycles on engine on daily commute? Not making excuses, just plausible causes?

Would a catch can have helped with this?

 

I would be interested to see the service records on that engine, it has always bothered me that Toyota insists on 10,000 mile oil changes. I posted that in the comments on the video.

I thought it was a fascinating video but to many gaps in what happened to the engine and its history to draw many meaningful conclusions from it.

 

The port fuel injectors should have taken care of that. These were mine on my GTI with direct injectors only, with supplemental direct port methanol nozzles.

This was with 40k miles on the engine.

I'm surprised to see as much buildup on those valves in the video.

 

Doing some digging this also popped up. We are the Type 21 engine.
