Do some dealerships let you buy engine cores?

So some dealerships let you walk in and buy an engine core from them?

AKA if they get a truck that spun a bearing in a 5.3, buy that engine from them? From what I understand, GM is pretty strict about wanting anything that was repaired under warranty back to use for quality control inspections, aka figure out what failed and why. Outside of warranty, I don't know much. I've heard stories about people buying them, but usually it's "from a buddy who works at the dealer".

I remember the chrome Buick wheels from the seventies they had a little rust. The Buick rep caught on and started hitting them with a hammer so nobody could use them anymore. They looked good cleaned up!

I wish I knew someone that worked there. My 6.2 has a knock that comes and goes. I always expect the worse so now im trying to save up to build another for my yukon. Haven't really gotten a chance to get under the truck but sounds like it might be a wrist pi . Really need it to to be at 100 precent. Only bought it because I had another child and needed something built like a tank. I think I made the wrong decision now. Oh well. ..

Comes and goes??? Can you elaborate?

I used to have a 454 that when you cranked it in the morning it sounded like it had a rod knocking but after warmed up it was quiet.... turned out to be torque converter bolts were a little loose.

I hope that's all it is. I'll have to look and see Today. Here's the thread

Yep... Sounds just like mine.... Aftet it warmed up the metal would expand and the bolts in the torque converter weren't loose enough to make noise any more.


Keep us posted on the outcome.

I agree with checking the TC bolts, had that happen to a buddy of mine on a different car, made a terrible racket, they thought the engine was toast.
