raddling sound?

[SRrunner]

i have been working in the engine bay and today i noticed that there is a raddling (spelling) sound when ever i go over 3k rpm's i was wondering if anyone has any ideas? hoping its nothing to bad...

[Roger_cha]

if there is a raddling noise where does it come from is it from the front of the engine or the rear or the top of the head or the bottom block.. more info...

back of the engine bay but lower i thought it was exhaust raddle but i checked that over and its not

[s3teen]

man... I have the same problem. I thought it was the plastic peice that covers the steering column or the dash. It's exactly at 3k too! It's wierd ...AND ANNOYING. Doesn't it seem like it's this really annoying guy saying "SHIFT"?

lol yea, i put a torque wrench on my exhaust and it helped a bit but idk what else it could be

it could still be the exhaust. I had a problem like that a few years ago, took a muffler shop guy about 45 seconds and it was fixed.

As the engine revs at different speeds it produces different vibration frequencies, and depending on where things are in the car and how they're mounted/fixed, they will resonate differently at different engine speeds.

Right now I have solid engine mounts, you'd be amazed how the rattling shifts from one place to the other as the engine revs.
