New TBSS owner, catastrophic engine failure on road trip home from purchase!

Hey everyone, I just joined the TBSS club on Friday! I flew from Denver to Orlando and picked up a 1 owner 65k mile Blue 3SS! Was on day 3/3 of my 28 hour drive home to Denver, when out of nowhere I suffered catastrophic engine failure. The kind that only happens when you thrash your vehicle too hard all day at the drag strip (which of course I hadnt done, just highway cruising with a couple downshifts to get around a semi, nothing crazy, nothing over 90 mph or even close to redline).

So I was cruising at 80 MPH on the interstate and my engine suddenly lost power and the gauges all flashed. Out the rear view, I couldn't see anything (the glass was covered in oil) side mirrors revealed that I was blowing a white smoke cloud and spraying an oil slick as far as the eye could see, and then the motor cut off. I was hoping it was just a blown head gasket. But the leak was coming from the bottom of the block.

The shop here in town confirmed my suspicions this morning that its the motor.. It threw a rod through the block, and punched a hole all the way through. My SS is dead. RIP! So now I'm 2/3 of the way home broken down in Manhattan KS and trying to get the dealer I bought it from in Orlando to buy me a new crate LS2, AND pay for the labor, of course.

Thoughts on what I should do? I am not interested in accepting a rebuilt motor, it only had 65k original miles on the odometer! Should I try to source an LSX block? I see a lot of guys do an LSX swap as a mod... is that more reliable/more readily available in 2023?

I will say, until the motor blew, it was the most fun 1000 miles road trip I have ever driven. And I can't wait to get my baby back...

Nice to meet everyone!

Sorry to.hear about your luck. Were you going up hill by chance? These vehicles have the oil pickup in the front, so if you punch it, you send the oil to the back away from the oil pickup, and if you're going uphill you exacerbate it by that much more. It's probably pretty easy to blow the motor up on the rear air springs (soft) punching it uphill.

I guess the question is what's your budget? You bought a roughly 15 year old used car, so I wouldn't expect to get anything at all from the selling dealer, especially given how far you drove it. If it had blown up in front of the dealership, maybe. But 1000 miles away, they're probably going to say "sorry about your luck", I know if it was a private party deal that I sold, that's what I would do.

Anyways, options. You can source another ls2, and swap over parts. You can replace the block and swap over parts. You could drop in an ls3 or l92. Hell you could go bananas and do a whole 6l80/L92 swap. It really all depends on budget. An lq4 iron block is likely the cheapest option, short of swapping a whole 5.3 in. I think I'd lean towards the L92 route, it's basically an ls3 with a different cam and a truck intake, so it's a bit more power than an ls2 and it's widely available. It does have issues with lifters, so I'd address that in the swap.

Thanks. Its just the latest in a never ending series of bad luck events. This has been the worst year of my life and its only April... but part for the course for my 2023. Needless to say budget is zero unless Florida's lemon law and 30 day buyer's remorse law applies and dealer to pay for a new engine... doubtful. I know.

No, I wasnt going up hill. Was going down hill actually. None of it makes any sense. I did find blue flecks of something on the inside of the oil filter cap which the mechanic who looked at it said could be blue devil which is posed in the Volant reservoir to go head gasket leaks long enough to make it someone else's problem... I think I got taken for a ride
Florida has no cooling off period, nor any warranty on as is vehicles. So unless the dealer does it out of the kindness of the heart, or you bought an extended warranty, you're on your own

I don't think you're gonna know anything until you tear it down, but issues like this are very uncommon, outside of being oil pickup related. Blown head gaskets on LS motors are virtually unheard of.

Sucks to hear, sorry you're going through this. Let us know what you decide to do with it. If you end up selling it, sounds like it'd make a great project vehicle for someone.
I think the AWD may have some sort of effect on it from the extra grip, but not sure what.

I would imagine having a softer rear spring (ie air springs) makes it a bit worse too.
