Name That Rattle

    I have an '01 Ford F-350 with a V-10. While accelerating there is a rattle that happens right at 1800 rpm. The noise only lasts for about 25 rpm (1800-1825 rpm) and sounds just like a loose or broken heat shield because it has a thin tingy sound. I went to the hardware store and bought a whole army of hose clamps and strapped every shield in sight down with no results. The thin shield on the transmission that covers the torque converter was a little loose, so I wedged a screwdriver between the shield and the front of the transmission but the noise was still there. There has been some discussion on here about V-10's exhaust manifold studs breaking off but mine are all there, besides that, this noise sounds too "thin" for that. I'm just hoping some one else has had this problem under warranty and were told what it was. Thanks.

    if i was going to look under the hood while the engine was in gear and revved, i would pull up close to a solid wall of some sort...just in case. :)

    also, are you sure there isn't a heat shield that you can only access from unnderneath. i don't have any specific info on your truck but i had a car once that had a shield under the manifold. i couldn't see itunless i was under it.

    What about the y pipe. I've heard of some issues with them. I don't know any details though.

    Could it be pinging ? Try using the next grade higher gas a tank or two and see if it go's away .

    Mine does the same thing, I'm pretty sure its the heat shield where the exhaust splits, I'm gonna weld mine back the way it should be and see if it stops the noise.
