If the main bearing shells spun (which is typical) then the block is trashed too. Dealers here charge such a high labor rate, that its cheaper to replace an entire engine, than it is pay the labor needed to repair it.

As for the 0W40 oil, no it will not fix bad machining or remove debris that was left in an engine, but it does provide an increased safety margin with literally no downsides or adverse affects (other that perhaps it cost slightly more) .There is no use case, no scenario, no environmental condition ( not a single one), where 0W20 does a better job than 0W40 at protecting the engines rotating components. The only advantage 0W20 has is it offers a slight increase in fuel economy.

You keep repeating the 0-40 and 0-20 oil mantra over and over again, as if you're trying to convince yourself. I'll tell you another funny story. The Escalade V has been running on 0-40 oil since the very beginning, and it has the same problems as the L87.

And you keep repeating what are blatant misinformed lies. Take the time to actually read what I wrote (assuming you understand the language).
Physics does not change when boarders are crossed, 0W20 still NEVER outperforms or protects better than 0W40 oil in any situation, regardless of how the truck is being driven or what ******** the truck is being driven through

Hey @Vladimir2306 and @Antonm, I am good if you two disagree w/ one another. But, please start your own thread entitled something like "Vald and Anton's discussion on the merits of 0W-20 vs 0W-40."

I posted this thread so folks could understand the experience I have with my 6.2 and it's replacement.

Fair?

Just got off the phone w/ my dealer, he is keeping me up to speed on the overall progress, working to get my alternative transportation upgraded from the Malibu (complete with some tires at about 3/32nds of tread that I am sliding around on) that Enterprise gave me to something more comprable w/ my Yukon XL. A full size SUV was requested from Enterprise, but they didn't have any at the time. He asked what my holiday travel plans were, and I shared them. He is working to get me some comparable wheels before I need them.

He also promised to check in with me along the way and keep me abreast of the expected engine delivery date. No good ETA yet, but they are asking GM to try and move it along.

Dang man. Sorry to hear about all of this.

Is yours the first post-PICO-pass ("PPP"?) here to crap out? Or have there been others that I missed?

Far as I know, yes...
That just reinforces the idea that the PICO test isn't very effective.

Keep us posted on your replacement timeline -- and also on any feedback if you've suggested to GM and/or your dealership that maybe the PICO test doesn't do what it's supposed to.

I have wondered (with no proof) how many dealers did NOT perform the PICO test, but changed the oil, filter and cap, and then charged GM for the test under the recall and sent the customer on their way?

The dealer knows that if the engine fails, GM has extended the engine warranty coverage, so the owner would be covered (and if the engine failed, there could not be a PICO test done).

That's taking it a step farther, I think. But I don't know which is worse -- being told you passed a test that doesn't actually do what it's supposed to, or being told that you passed a test that wasn't even administered.

If I were confident that the test was very effective, then I'd be irate if the test were never performed. Personally, I don't have any reason to believe that my dealer didn't perform the test... I just don't know what I should take from it, now that there's been a failure post-pass/with the heavier oil.

All the test can really do is detect EARLY signs of an impending failure before the average driver notices the engine was not built to spec.
The test will NEVER make up for the fact that GM built millions of subpar L87s - all the test proves is that some were even more subpar than others.

My warning to you all, is that the number of L87s that will exceed 200,000 miles would be similarly embarrassing to GM IFF they cared -
but they do NOT, which is why it's only '10 years or 150,000 miles' on the replacement engines; if they'd greater confidence the warranty would reflect that.

Anyone with half a brain (so that does not exclude all dealerships) knows that's a huge liability if someone gets hurt.
But money sure does talk...

Sorry this happened, and I think you're wise to keep this one once the work is done. It will be a known quantity for you and is equipped just the way you wanted it.

The long tail of this whole saga is that the market will lose priceless confidence in what for decades has been a durability stalwart: the GM V8-powered SUV. You and I know that the L87 is a modern design - only sharing bore spacing with the old 350, but most of the general public doesn't know that. If the old adage is true that trust is lost in buckets, and made up in drops, GM will be many years in recovering their reputation from this - if they can.

Wouldn't be the first time a vehicle manufacturer knew an life threating fault was present and chose not to do anything about because the cost of fixing the issue was more expensive than the lawsuits.

Ford did exactly that with the Pinto back in the 70's, see link below to an article talking about the infamous "Pinto memo".

https://www.spokesman.com/stories/2008/oct/17/pinto-memo-its-cheaper-let-them-burn/

GM is a business , all businesses are in business for one purpose , to make money (for GM the whole making cars thing is just an annoying middle step in the money making process).

All major/ publicly traded companies are ran by gloried bean counters, and every decision made is based on nothing except what will make the books look the best at the next meeting (usually because the decision makers pay is directly tied to company stock performance).

So yeah, GM (or any other business for that matter), will 100% let people die if paying the lawsuits costs them less that fixing the issue. This is such a common / well known theme that even Hollywood movies make fun it,,, remember the opening scene in fight club (great movie BTW if you haven't seen it) were the main character describes what his job is? He described making the calculations that decide if a recall was the financially best way to go or not.

Post edit: Here's a Youtube clip of that portion of the movie (link below). Pretty mainstream thought process if movie studios are making fun of it/ using it to demonstrate something the viewer knows to be messed up for the purpose of character/ plot line development.

Wow, just saw this... I thought 0W-40 was the miracle oil... I hope for the sake of the others that passed the pico test and running 0W-40 that yours was a one-off ... either the pico test passed by razor thin margin, or something was not done correctly at the last oil change at 43,200 miles (like using another oil instead of 0W-40 - human error). And, feeling sorry for the trouble you are being put through here.

The PICO scope test has to be submitted to GM, along with the scope data, to get the Pass/Fail result. I would bet that GM is tracking the associated VIN, probably read from the PCM. They may also be comparing mileage and other values to known vehicle-specific data.

Of course, there may be ways to falsify the test data.

The pico test was eye wash for the nhtsb. The oil viscosity change was to buy time.

Oil viscosity change to 'vette spec 0w40 - instead of 6.6L L8T spec 0w30 - does two things.
Second is to help move more of a product - 0w40 - that most normal people normally avoid.

Damn. This is crazy. Glad you were near the dealership instead of getting stranded middle of nowhere Mike.
