After autocross on sunday I noticed this wierd noise coming out of my car. I have no idea what it is, I found some videos on timing chain tensioners, but this does not sound like it.

The sound comes and goes, in the video I was reving the car up just a little and letting the idle drop down so it would make the noise so I could record it. The noise will come on as I am driving, and seems to only be there when the car is warmed up. If it comes on while I am driving I can give it a little gas and it either goes away or quites down to where I can't hear it.

Hopefully you guys can help me out.

Here's the video.

Can you do it again without the wind noise? Also, can you setthe camera down on the edge of the engine bay?

 

Yea I'll make another one when I get home.

 

Nevermind I found out what it was, my left motor mount was loose.
