Knocking noise
I'm getting this weird knocking type noise above a certain RPM, but my engine sensors arn't detecting it, but I can hear it. I noticed it when I revved my car in neutral with clutch out when I was coming into my garage. I heard it at around 5500 RPM. It's a pretty loud knock, any ideas as to what this can be?

Hmmm, does it sound like detonation to you? Other than that, I'm clueless.

Its a rod..
take it to your local piston shop they'll fix'r right up fur ya! 
no really though, can you tell where its comming from? have somebody hold it around 5k rpm. And put your head close to the open engine bay, and see if you can determin where its comming from? is it a sharp loud knock, a more dull muffled knock. stuff like that.
