I tried recording the noise but my camera sucks and there is too much other engine noise and fan noise that the camera won't pick up the clattering noise. I already tried that bud. Now I don't think I have a rod bearing bad, I have been told that I have one and I am skeptical because I drive 60 miles every day and it should have broke by now. Not to mention I have a led foot. I'll post the vid I took and maybe you can get an idea.
