Went for a drive in the stang tonight and started hearing a little knock and it got louder by the time I could get it back to the house. I checked the oil, its full and clean, I only bought the car 2 weeks ago, it hasn't been driven hard since I got it just around town. Anyways I wanted to see if anyone might recognize the sound, I'm thinking lifter or rod or something....

Here is the video

Exhaust leak or a rocker hitting the valve cover?

Thats what I had thought at first, when I got home I popped the hood and left the car running, I used long metal extension and put it on the top of the valve cover to try to feel vibration from a rod or something and there was no unusual vibration. I guess I need to put them car up on stands and look underneath...

sounds like a leaky header gasket to me, that's why it got worse. Is there a vibration with it? If not, then deffinatly an exhaust leak.
