Yeah....I know...used car...bs warranty....upside down on value.
Hopefully it works in your favor, just be ready to argue and read up on your warranty terms.

If you've had regular maintenance (oil changes, etc.) and no engine mods, you should be fine.
Looks like maybe a connecting rod punched a hole in the block. Hard for me to tell from the pics.

Like Long said, read your warranty. More than once. Be firm. Go get 'em!

Not keeping the car. But I鈥檇 like to fix it somewhat right. So 2011 3.6 out of an awd CTS sedan, coupe vs 2wd are all interchangeable? I鈥檓 needing close to a direct swap. I can change accessories but this is engine is not salvageable. Death by timing chain.

I need to get this ordered ASAP. I appreciate the help guys.
I am about to take delivery of a 2010 CTS 3.6 Premium... with 85k.... I want to change the timing chain immediately since I keep hearing/reading about it on this model/engine config. Are there any aftermarket upgraded timing chains out there for the 3.6? Like any stronger chains/sprockets or anything?

Cloyes makes a good kit according to a number of people here. I went with OEM since mine went out at the 100,000+ mile mark - if the second set last as long, they will outlive the car.

I am at 170k on my car with out any issues currently with the timing chain. Just hoping to get my new job and work a few months before having a couple more issues taken care of on this car. Been a good car so far. Other than the transmission going out at 170k after it sprung a leak.

From what I've gathered, the stock chains tend to elongate at the connections between the links. This happened on earlier model years, and is something GM fixed in later years. Any quality aftermarket timing chain brand has probably corrected these issues. Beware of any timing component containing Chinesium. These could cause catastrophic failure and at the least would necessitate repeat work.

You're way ahead of schedule without codes at that mileage. I would use 3 to 5k mile oil changes and wait until it needs it, or reaches the mileage that some GM techs recommend it, ~130k miles. If you receive the car in good working condition I'd have to say a timing chain replacement is over the top at this point. There are many, many 3.6L motors well beyond the 130k mile mark without problems on the OE timing components and some well into the 200k mile range. If it's something you feel you need to do, that's understandable, but if you're operating off of hearsay and paranoia I'd advise against it. The motors are very dependable when taken care of.

I would agree with this.

LS swap!
Plenty of info will rise to the top of a search in our Performance Mods subforum.
