BREAKING: GM is officially recalling the L87

All I have to do say is "Lucy you got some splaining to do!"

Some may get it, others are probably too young!

If that's true, then it means no replacement for 100% of the engines in the recall window?
So basically an inspection (whatever that entails to be seen I guess) and then replacing only the bad engines?

IFF the engine goes bad before either too much time or too many miles have elapsed,
THEN you get a replacement.

I work at a Chevy dealership and all we have been told is that if your vehicle is in this recall then you will have to go to 0w-40 oil and the first one is for free then you are responsible for paying for 0-40 oil changes in the future which are gonna be more expensive than the 0-20. We did a Camaro Friday that was an 8 quart 0-40 oil change and it was $140 where a 0-20 would have been $88.

Sounds like the difference between using mobile 1 and gm’s dexos

You guessed it, Rod bearings !!

This is from a 2019. The Rod bearings do look like they have very high mileage on them, but this engine has less than 50K.

Ok this appears to be a major development:

The “replace all engines built before a certain date” bulletin is now on the NHTSA website. Looks real, and looks like the oil change fix is no more.

Your missing key words in the document… “may”
They are looking for specific units, but obviously don’t know which parts went where went in which engine.

The ones that are deemed good today will get a special warranty for engine… 150k/10yr… really not an exciting recall, they are taking care of the defective internal parts

GM's still trying to get away with as much as possible by spending as little as possible.
If your L87 makes it past 150,001, yet fails before 200,001 miles, it's definitely YOUR fault.

I don’t see “may”. I see if the engine was built before 24183, identified as needing engine replacement.

Watched whole video. This guy does good teardown reviews. Seen a few of his before.

The varnish looks pretty bad for 50 k miles. This is a sign of oil degradation. The 6,000 mile oil changes that were listed may be one thing but did owner push it to 10k,or 15k once or twice?

The bearing wear also looks like a heavy load. Could be a degraded oil too. Is this also from DFM? start/stop (spending alot of time in boundary or mixed lubrication on the stribeck curve?)

Given the condition of the remaining bearings likely reflected the condition of the failed bearings, it wouldn't take much deviation off of spec on the journal to cause this--especially if the oil condition was sub-optimal.
