Is that what that sound is? I thought I had a cat. conv. going bad or something. Low speed on acceleration is when I hear it.

I'm guessing its the corrugated heat shields on the egr tubes.
Am I correct?

Whom are these people saying this? I've never seen or heard that before and there is only one egr tube, it runs from the top of your intake to the passenger side of your block, its the hard metal tube on top of the engine. I cant see how thats making noise.

I must be the 'People" but yes the metallic tubes covering the EGR pipes will rattle at various RPM's ( mine happened above 3k rpm's when hot under acceleration, It must have been just enough vibration to make this sound) I spent months and many trips to the dealer only to be told my "Rattle" was normal and they could not find anything wrong with my Jeep! I knew something was making this noise and upon tapping on everything and moving things around I found these coverings were not clamped down and if they are loose you could flick them with your finger and they would make a metallic sound. I clamped them and NO MORE NOISE!

There are 2 pipes and the one that runs straight down the back of the engine and firewall was the culprit, it sounds like it comes from the transmission or bell housing housing area or possible bad catalytic converter. after messing around with it for a while before clamping it I tried pinching it tighter and the sound just got different but after clamping it, it was gone.

I was just fucking around... I find it humorous when people tell me "they told me..."

Can u snap a pic of where you clamped the tubing?

How about a pic from up top pointing or highlighting which one it is? And a pretty good description as to where you clamped it up?

I'm interested because I have a rattle that one dealership said was my CF clutch and another said my catalytic converters are bad but were baffled as to why I had no emissions issues

I can't get a pic uploaded right now but you can't miss them, Start from the very top center of the engine right where it says 3.8l and the intake runs into throttle body (very top)and look at the metal tube and the metal tube covering it and then trace it to the back of the engine and look for the other metal tube covering running behind engine with it's covering on it neither are clamped.

I'm joining in on this, not because mine rattles (yet), but if it does I want to remember this thread and see some pics or get the updated replies!

Well I do believe that "they" are right about this...

I had a rattle on acceleration that I couldn't pinpoint. I took a hose clamp and tightened it down on one of the metal looms that covers the EGR valve piping and voila! No more rattle.
Edit: I took a pic but it's not uploading via tapatalk for some reason. I'll try again later

Bingo, Thats the one!

Glad "They" could help

P.S. How many paramedics does it take to fix a rattle? Obviously 2, I guess thats why we work in pairs!
