Interesting informed take on the Tundra Recall

I imagine if they had identified the problem and developed a new part in January of 24 they would not be installing the "old" engines after the date of the new part. Why would they continue creating problems for themselves?

 

How do you know a "old" engine was installed?

 

I don’t know, and I guess I wasn’t clear what I meant. I was saying it would make sense to me if Toyota ONLY installed new engines starting when the new part # came out. They wouldn’t continue installing old engines. I also felt like that is what TCCN was saying. Unfortunately, it is all speculation.

 

I think the challenge is trying to read between the lines in the recall notices.

Why would we need a different short block if the debris issue was fixed in early 2023? Wouldn't all the engines be the same if there was nothing wrong with them other than debris? Did Toyota switch the main bearings to a more debris tolerant metal?

We would need to know what the part number is for the debris

This smells like someone put a red herring in the heating duct last week!

 

What happened to Ryan? He disappeared from FB too.

 

Aliens

 

But Ryan won't tell you to let the lord bless you and hold you?

 

But I believe he did suggest replacing your coolant with a 50/50 mix of Toyota antifreeze and holy water. ;-) Maybe that would exorcise our engine demons.

 

Im not convinced we got the whole truth. Something isn’t adding up to me.

 

Based on the part number change and as implied by TCCN, it appears that Toyota didn't implement a definitive engineering change (either redesign and/or change to manufacturing procedures) until January 2024. However, in the letter to NHTSA they mention that they improved cleaning procedures some time between January and September 2023. Most likely Toyota only recalled early production vehicles because they are more likely to fail due to mileage, and are waiting for more results from the interim change implemented between early/mid 2023 and January 2024. It is possible that they will expand the recall to newer (pre Jan 2024) vehicles at a later date.

 

My manufacture date is 2/13/2023, also have a hybrid. Hope I dodged the bullet both ways.

 

New PN does not have much value.
The PN can change for many reasons such as change of supplier, change in another unrelated part/process. Why hasn't the PN changed when previous cleaning processing improvements occurred?

Too bad Ryan never got around to sharing his short block dissection.

 

I thought it was a good video. Basically saying that if it was a blockage, the rod bearings would go first, which makes sense as they'd be more starved of oil than the main bearing. Also confirmed that the debris

The current offerings of 0w20 limit zinc/phosphorus. So generally 800 ppm is what you'll find. I highly doubt that is an issue.

Cleaning procedures happened after that. You are in the zone, but excluded because hybrids have motive power to pull over...

 

Exactly the point I was making to AZ. ZZDP is an anti-wear agent and the zinc levels we see are normal based on the oils we use, as noted in the analysis reports.

 

I have to hand the Nut a point for mentioning the number of failures could probably be much higher than the official number given by Toyota. What he claims make sense. At least some of it.

 

Yeah, he is always really straight with his presentations. And as a Toyota fanboy you can see how much this hurts him. He grimaced and used the very expression that I have told my friends: this is really bad. But I am keeping my faith for now that Toyota will do the right thing by us.... unless and until they do otherwise.

Also interesting to see he left his job as a Toyota tech and opened a shop. I wonder where it is?

 

He is located in Chicago

 

I belive toyota told the truth about engine debri. Do not think its design flaw or oil type related. After changing my oil twice on my 24 and seeing the size and qaunity of debri. I can relate to there claim I think they do not have a full grasp on how many engines. No matter the build date are contaminated.

 

Did any of the debris look like the fine black casting sand that is often used in making the heads? If you had to guess the amount of total debris would you say it would fill a soda bottle cap? A concern I have is any debris caught by the filter has to go through the oil pump first. If it's casting sand it would ruin an oil pump very quickly and starve the engine of oil.

I haven't seen anything but a very few metal slivers in any oil drain pan or filter for years. This is from Honda, Fiat and my 5.7. If I saw what some of the members here are posting, I'd be sick to my stomach and call a rollback to take the truck back to the dealer.

 

really where , maybe I’ll go see him , ha!

Yes black flakes like coffe grinds .So
me in the forum of a grain of rice just not as big. Some fine metal flake to be expected but also some large aluminum and some good bits of shiny brass. My filter cut looked cleaned to my findings only a few metal flakes. If you look at the tundra oil pan it has the little dimple bowls wonder if they settle in that.

 

thanks, hell, he's not far at all from me

 

You would think ZDDP having an issue with silver bearings would cause the problem with the other bearings as well and just not #1 bearing and to a lesser extent #3 bearing.

 

A part and a process are two different things. The process is not in the BOM

 

Part numbers do not change without a reason. Engine material would not affect just one or two bearings. Toyota is lying about the issues.

 

Crazy times when people like me are thinking of jumping back to a domestic versus “rolling the dice” on buying another Tundra . I’m sure Toyota will fix the issue eventually, but in the meantime, it sure seems like there will be a lot of folks waiting on “goodwill” repair/replacement approvals from Toyota corporate when they’re out of warranty. I feel for you guys.

 

Part numbers change for almost any number of reasons. It could be something as simple as a different package or color or minor thread depth change to hole where a bracket mounts. Conclusion jumping seems to rampant on this forum. Toyota will fix it and treat the customer right. Remember the frame recalls? People with ratted out Tacomas on the way to the scrap yard got new frames.

 

A 40 minutes video filled with speculations and theories isn't much help. Everyone needs to chill out and wait until Toyota rolls out the details of the recall. It should be forthcoming next month.

Having said this, his comments regarding full engine replacements versus short block rebuilds makes sense. And the timing of the 350 new hires in Alabama is interesting.

 

There was an interesting info that AMD did give about the numbers Toyota reported.

824 Warranty Claims: This means that these are the claims where the work has been done and the dealer got paid for the warranty work and the claim is closed
166 Field reports: This is a number that is part of the 824 Claims not in addition to.

The numbers don't include any trucks that are currently in repair waiting on parts, nor any that actually had this issue and then Toyota Denied the warranty claim.
