BREAKING: GM is officially recalling the L87

[OR VietVet]

Interesting read, if true GM is developing " diagnostic tools" to test for bearing damage.

Possibly something like the vacuum system another manufacturer developed and used.

Special Diagnostic Tools

The special inspection tool is a scanner and if a P0016 comes up then the oil change process happens and a 0W-40 oil cap is installed.

The special inspection tool is a scanner and if a P0016 comes up then the oil change process happens and a 0W-40 oil cap is installed.

It appears that the oil change happens if the code DOESN'T come up, and the engine gets replaced if it DOES. (Even then, it doesn't sound as though the code not coming up excludes you from an engine replacement.)

IFF an L87 built within the suspect timeframe
fails before it accrues too many miles,
or
fails before too much time has elapsed,
or
throws code P0016
GM owes you either a repaired or replaced L87.

How many are "too many miles," and how much is "too much time"?

I wonder what’s failed more? The 6l80e transmission or the 6.2l engine.

Exactly what I meant to say and typed wrong. Thanks for catching.

The 10l80/10!90/10l1000 valve bodies are failing at a high rate. I expect the 2024/2025 are likely to recalled in the near future.

Sorry, sometimes I suck at number memory (it's why my alignment specs are 'MAX Caster. No +Camber, slight -Camber. No Toe OUT, slight Toe IN.)
GM recently revised the warranty for suspect L87s, extending both time and mileage under warranty.
The revised duration and mileage -
TEN Years or One Hundred Fifty THOUSAND miles, whichever comes FIRST (if not mistaken)-
answer your questions.

If you don't how the Magnusson-Moss warranty act works, you're far more likely to defend GM,
and skrewer yself out of a repaired or replaced L87.
Y'all have an opportunity here - don't squander it.

Sometimes the right thing to do is the right thing to do even if you fail, so I'll try again:
GM built tens of (if not hundreds of) thousands of subpar L87s.
Despite that the LT1 & the L87 are nearly identical, GM tried to build the L87s so cheaply,
that 0W20 is no longer sufficient protection.

Those of you included inside the parameters of the recall - those with L87s built subpar -
have 10 years or 150,000 miles to suss out how to get GM to repair/rebuild or replace your L87s.

I know exactly what you are saying bro! Definitely good advice for those who can read between the lines!

For those of you advising on changing oil at 50% of OLM, is this mileage based or time based? I had an oil change at 1 year because my OLM said I was at 0% yet my mileage was only 2,697. Asked another way, is time a concern with oil quality or is it mileage that dilutes it over time?

I think your idea of the unfortunate outcome of this mess is very close to reality.
I worked for 42 years in an automotive assembly plant in different departments all over the plant. Your words bring back memories of things that happen from either laziness or the pressure of “ make production goal”.
Its always the customer that pays the price.
I had three 6. 2 engines failed and it was a terrible experience.

Three?!? I second guessed myself .. but was talking to my BIL - if my Yukon is on the engine replace list, it’ll be my fourth 6.2L in a 2023 Yukon (over 2 vehicles, both 2023) . Insane. Feel like I should be up for some type of award. Anyone out there going on a 5th motor?!?

I like your logic. It would be some reassurance that GM is trying to do the right thing.

Agreed
