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

It's like eating crawfish without washing and rinsing before boiling!  I see you are from the real part of LA. 

Crawfish? Spicy with Budwiser?  It`s still crawfish season now. Get em while they`re here.

I get it. Just can`t figure out why a large corporation like GM can clean all their blocks, crank oil passages, heads, etc except one RPO. They outta ALL be trashy.

Cleaning is one thing, but what if something was actually MADE out of spec by ten thousandths. Could take a bit of time to show a problem, but eventually will. Maybe there is a bad journal, or bad rod. Maybe they weigh all the rods from one manufacturer going into the Vette motors to get balance as good as can be for a production motor, but the product manger for the trucks authorized the use of rods from any manufacturer in the trucks, and maybe even mixed batches, or worse, mixed manufacturers. That sure would make a difference. Of course, just postulating.

 

Interesting, though, that they know the exact date range of the affected motors. So, they know exactly what's wrong, which will eventually become public, but they will likely not share HOW it happened.

10 thousandths is HUGE. Maybe .001 to .0015, maybe .002 out of spec. That would still cause problems right off the assy line. Especially if it were .001 or more too tight.

I haven't followed this whole thread so maybe someone has already mentioned this but if not Lake Speed, Jr. "The Oil Guy Geek" has a You Tube Video out on the 6.2 recall. I highly recommend if you have one of these affected engines you view it.

Maybe I worded it wrong, but you know what I meant. 😉

There are SO many videos on this. Do you have a link to the one you specifically mentioned?

Has anyone tried trading one of these in yet? Carvana gave me a quote, didn’t love it but it was a quote.

 

Wondering if it’s not better to just dump early and move on to something else rather than deal with this bs.

What model and trim do you have, and what was the quote?

Carvana can be very generous or very low. Depends on what’s selling for them.
 

I sold a truck to them last year and the process was super fast and easy. So if you do get an offer you like, I wouldn’t hesitate to take it.

You can try and dump but prepare to probably take a hit on it as on the wholesale side of things they are staying away from them and the prices are dropping down.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
