BREAKING: GM is officially recalling the L87

[07Burb]

All I am saying is that I remember the thread passing 200, then recently it was back to 100. Just what I saw. Am I wrong?

Never paid attention to threads and page count to that detail. It's possible that @MADDOG possibly made an update to where each thread has 20 posts per page rather than 10 posts which would impact page count but not delete any data.

@GMCnewbee

Am I imagining that each thread used to "page" at 10 posts (post #11 on page 2, etc.), but now it's 20? That would affect the page count.

I remember the start of this thread back in April. Post #1 is indeed the first one.

Maybe someone deleted all the childish oil weight bickering. That would have cut the thread in half






Of course, I'm kidding.......kinda lol

I'm not questioning some of your knowledge or your work history, just some of the statements regarding this issue. And as for being retired it was just recent so not 5 or 10 years ago so I know what goes on at GM and I worked on all major truck programs starting with the GMT800. Is everything good there, nope not at all and I would be the first to admit that, but to say safety margins are thrown out the window is not accurate. . This is an issue that started with the crank journals and machining done in Mexico and not the bearings. From your statement I can see you have a very negative view of GM and that is your opinion, not sure as to what vehicle you have that is affected by this, but as I mentioned this has affected me and yes it does p#$@ me off.

As for your statements regarding computer modeling, yes a lot of this is done on all subsystems for the vehicle. But to suggest that real world testing does not go on anymore or vehicle subsystem tear downs and validation testing is absent is just not true. These major programs are worked on about 5 years in advance before they are ready for saleable production.

I worked for an OEM supplier of heat transfer and HVAC equipment. Computer modelling was very valuable in zeroing in on the proper design quickly, but everything was verified by extensive real world testing before an OEM would sign off on it. I have no doubt that the machining and debris issues are the root cause of this problem. 0W20 opinions however, litter the forums of every manufacturer who has spec'd it for over a decade now.

I don’t see anything in @jfoj post that justifies your mockery.

In fact it is rather dishonest to say he thinks the computer models are wrong.

He is saying the models can be wrong if assumptions that are inputs are wrong. Further that previous established qc methods have fallen out of favor ; and these methods could be useful in verifying the models.

Im enjoying all the knots we are getting tied up in.

Let me know when you guys create some products to take advantage of GM engineering mishaps.

Honestly band together and make an LLC, approach GM as a 3rd party quality assurance engineering team (credentials be damned, we got google/open ai)

Send them your proposals so we can finally fix this snafu once and for all.

The conclusion is:

Engineering models are wrong, modern engineering and manufacturing processes are all wrong, these vehicles are all largely unreliable, the oil they chose is wrong, the recall is wrong, and we blaming it all on BIG GOVT correct ?

We missing anything?

-----We should create a poll-----

0w20 gang as one category

0w40 king bros as another category

I hate gm I drive a ___________. as the third category.

Im just here for the food. As 4th and final category.

Let's have fun with it.

You forgot:

Every single thing GM did in design and manufacturing these engines is perfect, and any notion to the contrary is subject to pathetic mockery.

All models ever made by anyone, any organization, institution, or oem, are infallible to the point of being on loan from God.

All technology must be goal-tended else someone will shame you for being a Luddite.

No no no. The oil. There is conspiracy in the oil.

You and the one other guy convinced me after you said it 100 times and he backed you up on it.

I looked into a bottle of 0w20 and there was air bubbles in it. No doubt to create a wear condition. Those bubbles wont lubricate properly. I shook it up to see if my eyes were playing tricks on me.....guess what! There was even more bubbles after I shook it!

Whats crazy is the engine no doubt shakes. So those tiny little bubbles are part of the conspiracy too.

Im gonna conduct some tests and report back.

I've made no edits to the content of this thread. However, the comment that changing the view # of posts per page setting would impact the number of pages.

I've scrolled through all 108 pages here and cannot find any break in the data. I've also checked the backend on any changes made to this thread with respects to the number of posts in this thread and found no such change made.

I will now test how changing the # of posts per page impacts what we see when viewing the thread.

I will report back a little later on what, if anything, I find.

 

[MADDOG]

Well, all the data looks intact. I am still looking for the # of posts per page setting, but I did a little math to look at the problem from a different angle.

If you selected a 10 posts per page setting, and given that there are 2148 posts here, then the total page count for this thread would be 214 pages + 8 more posts. (2148/10)

In comparison, if you selected a 20 posts per page setting, and given that there are 2148 posts here, then the total page count for this thread would be 107 pages + 8 posts. 2148/20)

I still haven't tested the settings yet as I need to find where that setting is in this version of Xenforo but the math checks out.

Oil 0-20 in the GM engine, and in the L87, is so unique that it immediately kills the engine, completely and irrevocably)
By the way, to lift your spirits, I'll tell you a story about the GMT900) When the 900th body first arrived in Russia in 2008, dealers poured GM 5-30 oil into the engine, and when the cold weather came, cars began to be brought to the dealer that could not start at -5C-10C. They tried to drain the oil, but it turned into lard in the crankcase.

At first, dealers raised a wave of refusals, saying that owners pour some incomprehensible additives into the oil, change the oil at the owners' expense. and send it back, after some time the situation repeats itself. Then an investigation begins, someone seals the engine, and the dipstick. and the car comes to the dealer again. It turns out that one of the fuel networks had a set of additives, which, when in contact with GM 5-30 oil, gave the effect of a sharp increase in the thickening temperature of the motor oil)))) Such jokes happen) GM, then switched to third-party oil, then they started pouring Castrol, then Mobil, then ZIC.

Sorry, I did not mean to turn it into a math problem. I don't know why but I pay attention to the page numbers, especially on this thread. It just stuck out to me seeing we were over 200 pages, then we were back to 100 pages.

don't forget the "modern GMs are all junk, drive a GMT800 forever" category

No worries. I checked on the # of posts per page setting and, by golly, there isn't one on this version of Xenforo! So the page count is correct.

Maybe you were looking at the post count next to someone's post in this thread?

I recommend watching it, I think YouTube can handle the translation from Russian to English.

saw this on TikTok…not my video and not sure if it’s been posted already.

He is right, something happened with the page counts. I was bookmarking the last post I read and when I came back after a day or two I was always 2-3 pages behind. The last two weeks my bookmark seems to take me to the latest page and I thought that was weird because there were new posts. Meaning, if my bookmark was at pg 201 the thread should have been at 203-205ish assuming the daily post rate was somewhat similar. Also, I instantly knew how many pages behind I was.

Here is the title of my last bookmark

BREAKING: GM is officially recalling the L87 | Page 201 | Chevy Tahoe Forum | GMC Yukon Forum | Tahoe Z71 | Cadillac Escalade - Tahoe Yukon Forum

I am only seeing 108 pages, today. That book mark has to be about 10 days old give or take a few days.

Something is not right, I agree with you.

Edit- Maybe it is right if a bunch of posts were deleted. But I would have no way of knowing that. On other forums, the post numbers automatically change when posts are deleted. From what I can tell, this thread was at 201 pages at some point. Now it is at 108 pages as of this post (2,156). If more posts are deleted, I can use this one as a reference point.

Where would the posts per page setting be? I never changed that on my end. Also, I think a lot of posts would need to be deleted to remove close to 100 pages of a thread, so I don't think that's what happened. Personally, I did not change any settings that would alter the amount of posts I see per page.

 

[TrueAt1stLight]

Odd: I went into the GMC app today and my 2024 Yukon XL with the L87 engine no longer shows a recall. Huh. What’s with that?!? It had the first recall noted and I received the first letter in the mail.

@MADDOG

I didn't get an email notification or a forum notification with the 11:20pm post, yesterday.

Has something changed on the forum backend, recently?
