New bulletin/Campaign for '21 -"24 Silverado, Sierra etc with 6.2 L87 engine. Has to do with engine sudden stop (blown). Very early. No parts available at this time. NOT ALL 6.2's are involved. Which ones is unknown. Dealers have a list of inventory to inspect and stop sale if inspection fails. No much of an inspection though. Check for P0016. If it is there then stop sale. If not then change oil and filter to 0-40, change oil fill cap to reflect new oil grade, send it. Again NO PARTS at this time.

the real issue here is Metaldyne Performance Group who supplies most of the powdered metal forged and machined rods ASSEMBLED by Tonawanda.  As recent as 2021, JD Norman Industries sued Metaldyne over

Update(s)   GM sent dealers a new special tool to use with an existing tool, the Picoscope (fancy high end oscilloscope plus a whole bunch of other fun stuff it can do).  Its a knock sensor

WTF?

 

 

Corvette/Camaro/Blackwing 6.2 LT1, LT2, LT4 and LT5 use it currently as of 2019.  Nothing new.  0w20 was/is in the pickups solely for fuel economy reasons.

Boy oh boy GM has blinked. Metallurgical issues exacerbated by fuel dilution will only be DELAYED using 0w-40R by Mobil.

Buy enough time until they can get enough engines for full replacement perhaps?  Because I think that's what they might be trying here.  They know they won't be able to meet demand for it so why not stratify it.

It will be interesting to see if they cover past warranty, knowing there was a defect, or is it covered forever if the specific parts fail past warranty?  

 

There is always a better oil option. :)   https://www.amsoil.com/p/amsoil-signature-series-0w-40-100-synthetic-motor-oil-azf/?zo=521390

Most likely. @Black02Silverado has run Amsoil 0w-20 in his 6.2 with do far no issues.

After one year of being in charge of manufacturing this leader is resigning. Related? Maybe.

It would have been cool to be a fly on the wall in all of his meetings and offices to hear what exactly is going on.

Glad you posted that 0000 was for all of us and 0001 was just for dealers. I tried to get answers from two dealerships today and they said they dont know what to tell me lol. They see the recall but say there is no remedy for it. I said It says at the bottom to inspect then change the oil. They stated again it says at the top no remedy so there is nothing they can do.

The defect is the 0W20 oil 😏

Name it...the exact metallurgical ISSUE. Can't be done. Again, attempting to 'say a thing true'. :nonod:. PROOF! and failing motors is proof only that they are failing. REASON...LOGIC....

 

Not the OEM's first rodeo on oil related failures. Anyone remember taking all the Phosphorus/sulphur out of flat tappet cammed motors just before roller cams became standard fair?  And the hideous number of lifter/lobe failures? NOT metallurgical. Motors are not moron proof.

I am due for an oil change, I wonder if I should just swap out the 0W20 I recently bought for the 0W40 and go on from there.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
