So there's a guy in my area who had his vq35de (on a 350z) seize up on the highway. He had his engine replaced and is now selling his bad cylinder block and heads. He doesn't know exactly whats wrong, but apparantly it still ran when he added more oil, but it made a lot of noise. I'm just wondering what you guys think this would be worth paying for assuming it can be rebuilt?

 

less than 500$
