Hey all. I tried searching for engine rattle on the 2.4 but all results pointed to the TC/SCs. I was wondering if anyone had a clue as to why my 2.4 engines rattles when im in drive and idling. If i switch gears while idling, neutral for example, the rattle stops. It also stops when im in drive and I accelerate.

Is there anything that would cause this engine rattle only when Im in drive and idling?

 

Hmmm vid or sound clip would help a lot.
Have u popped the hood to see where sound is coming from?
U might want to hear timing chain area.

 

Check the heat shield by the exhaust manifold.

 

Ill try to take a video tomorrow and pinpoint the location, ill check the heatshield thanks.

But why would the heatshield only rattle in drive? and not neutral or park

 

Maybe the throwout bearing?

 

I have an A/T so I assume I dont have a throwout bearing, can an auto make a throwout bearing like rattle?

 

I've driven cars that did this and in fact my work truck does it also. Heat shield rattles in drive but no other time and would bet its your issue.

 

My car does the same thing

 

Lol it shouldn't. Sorry the way you posted made me think manual.

 

Shield could be loose or bent or broken. With transmission in drive puts tension on engine causeing rattle.

 

Buy a whole new engine and trans and call it a day.




Jk
