You are correct. There are 3 TSB covering what to do if there is severe engine damage/engine damage. They cover how to check for issues or how to replace parts of the engine. I doubt that they put out TSBs for one offs. It still may be small but I am not the only one having issues with engines. I do hope my issues is isolated to me or a couple of people. I would not wish this one on anyone.

I agree. I'm not buying the bad filter or contaminated oil excuse GM has so far thrown out. I wonder if the crank is walking. Or if the torque tube install steps at the factory allow for an improper torque tube install taking out the thrust bearing like some dealers have managed to do when changing out the tt.
C&D lunched two engines. One on a car that was tracked and one in a long-term test car, which if they didn't hammer on that one hard, brings me back to the tt as opposed to the crank walking, altho the latter can happen under moderate load as well.

Just because your Z06 allegedly have issues it does not mean our Stingrays have issues too. I love people like you with personal agenda trying to persuade others into believing something that is not even close to being real.
Oh well..such is life!

They say they now have all of the parts. The new thrust bearing is last piece they are waiting on now for them to rebuild the bottom of my motor. I do not know if it was bad or just replacing everything in the bottom of the motor. They said the issue was with the rod bearings but it could be the thrust bearing causing issues with the rod and rod bearings. It gave no notice when it failed just a quiet squeal and one load pop. The engine was not under any load, less than 1800 RPMs.
Good info - Thanks for posting.
Hopefully they'll you buttoned up and back on the road in short order.

Well I can tell you that I'm not a troll and this is actually happening across the country! I was able with the help from My Dealer to resolve our problem and got another vehicle but, Here are the picture's from My car that blew up. I am very nervous that until GM acknowledges that they have a problem that it may happen again to Our new car? Break In procedures were followed by the book on both vehicles!

Spoke with couple techs from various dealerships around here and no one has ever heard about a Stingray with engine issue. Only one blew up but that was due to missed gear. Going from 4th to 1st can really mess things up.
Why is it that everytime someone joins and have like 20 posts under their belt has heard of a "blown" engine but others do not?

Does the c7 come with a magnetic drain plug to catch metal? Of course, it would only catch iron/steel pieces and not aluminum. Aside from replacing the "faulty" filter issue, a magnetic plug could help.

oooph....i had a 2007 SRX with the 3.6 in it that let the timing chain go and motor popped at 15k miles.. my father got a notice that he had to have his timing chain tensioner replaced in his Traverse (IIRC) last year. GM makes a lot of cars but man it's starting to get a little nerve wrecking.
My friend has a performance shop and tells me he has had brand new camaro's in there getting heads cam where the timing tensioner is just laying in the pan! Switches them to the older LS2 style whenever he takes on apart.. and i know he has done a couple dozen DOD lifter replacements on trucks and cars with that system...
here i was thinking they had these problems behind them!

The 'engine grenaded' threads are disconcerting, and so far as i am concerned, have yet to identify the root cause.
of the threads i have seen, there are three, perhaps four conjectures:
1. 180 degree thrust bearing
2. flawed rods, crank and/or rod bolts (not design but one or more batches were under spec)
3. going 98 mph without replacing your oil with 10w/50
4. problematic oil filters that break sending metal parts into the motor
reminds me of the old bmw m3 engine seizure problem. bmw went to a new engine (forget what year) had a number of engines seize and refused warranty work for a period of time until a root cause was proven, leaving some number of m3 owners high and dry...

Good luck to those that have the problems. And thanks for reporting.
Cheers.
