Looking to get back in the G35 game. I went and looked at one today that has a rattle when you rev the engine.
It isnt a sound I've ever heard before. I made a video and uploaded it to youtube. If this is something I can fix, the price makes it impossible to pass up. Any help would be appreciated.

It also smokes at startup if that makes a difference

 

That sounds like rod knock to me...

 

i am gonna have to go with shermcs... would not touch even if it were free.

 

I figured it was something ridiculous. The guy claimed to have no idea about engines and was simply going to replace the engine without even looking in to the problem. Even at the price it's at, I don't want to deal with that
