So yesterday i was driving my car at about 50 mph and 2k rpms. then all of a sudden i started to noticed this noise coming from the engine bay, didnt sound like a knock or a ping. Started to get louder and louder (sounded like a peice of metal in the dryer) i pull over to the beefobradys parking lot off of old atlanta. The fucker pretty much died on me before i could make it all the way into a spot. So I'm thinking fuck, what did I (me personally do wrong). Called GM roadside assistance, they got it up on the tow truck with no problems and off. which i parked it on the street between gwinnett place honda and gwinnett place chevy. Couldn't sleep all fucking night last night, got up at 6:40 a.m. to ride over the dealerSHIT to tell them what happen and what went wrong. We told them the truth which i was driving and so they jumped to conclusion that I fucked it up being 18 years old. My dad had to sign a form saying that they could tear apart the block and if they found anything that had been tampered with it would cost him (meaning me) 1300 dollars. They found out that a peice of metal some how got into the first piston on the driver side, it scarred the piston wall, made the cylinder head look like a dog chewed it up like a peice of wood, and the top of the cylinder is fucked. Now we are in the process of getting a new motor. My dad's friend is head of N.A. operations for GM so he is going to try to get a new LS3 and if not they will ship out a new LS2 with some ambassidor (sp) plan that my dad's friend can use to get parts faster to him, friends and/or family. Later on in the day say 6:00 p.m. Chevrolet called us and told us that the catalytic converter had come apart and went back up into the exhaust valve and basically thats the noise i heard when it first started to fuck up and thats what screwed my up my motor
thanks for reading.
edit : btw they gave me a sweet red 2008 grand prix to drive![]()

or your dealer dude is trippin' hard

Sounds more like a valve seat let go and bounced around inside the chamber. I have seen that happen....






Just kidding.
