*******VIDEO ADDED AT BOTTOM**********





Hey guys, I'll try to explain this the best I can. I was on my way back from a friends house, and was going about 70 mph. The car was doing great all day, except as soon as I got home, my car started to make a really loud rattling noise that I can't pin point. There is NO CEL and the cars performance doesn't seem to be affected.

I've checked:
Timing belt - Doesn't seem to be loose or worn.
Exhaust leaks
Took off the valve cover and everything seems to be in place.
It has oil.

I was able to record a video of the noise it's making, but I'm not sure how to upload it onto this thread. If anyone has any suggestions or opinions, I'm open to them.
Thanks.

 

Not sure on the terms of service, do they allow you to upload to youtube then share the link here? That might be the route you need to go.

Common things to rattle, check your heat shields around the catalytic converter. Where they bolt on commonly rust and give way to let one corner or side rattle something fierce.

 

exhaust heat shield would be my first guess, although life the car up and inspect more thoroughly.

 

Yeah I'm about to jack the car up. But I don't think that it's anything like that, it sounds more like it's coming from the bay.

Finally made a video of the noise. I am not computer savy, so this is awesome to me haha. Hope this helps some of you guys figure out what this is!

 

I'd try removing the external drive belts (alt, P/S, A/C) and see it it goes away just to eliminate one of those.

Does it change with RPMs?

 

Yes just went out there right not and started it up. It changes with the RPMs.

I jacked the front end up and it seems like it's coming from the front left side of the engine bay. Sounds like it it something around one of the belts?

 

Bump. Anybody think they can help?

 

Sounds like something is loose/rubbing do as the other poster said and remove the 3 or however many belts you have(a/c/p/s even the alt)

 

Ok I'll give that a try tomorrow. Thanks for the advice so far guys!

 

Been looking and still no idea what is wrong...

 

Did you remove the drive belts and run it with them off yet?? If the noise is gone with the belts off its likely a a/c compressor or idler pulley, if it is still there it's most likely a loose tbelt slapping the covers
