I'm very afraid of what this sound is ...

Is there a way to attach a sound file?

It started out as a "random" noise, sort of a clunk, and then it was only on slowing down after revving. Within 15 minutes, it became an all the time noise. Seems loudest at the right rear of the engine, but you can also hear it very clearly in the left front wheel well. Varies with RPM, and doesn't appear to be the fan. Just changed oil about 2 weeks ago, and oil level is good.

Not sure what else to say. I'll try to zip the sound file and see if that can attach.

Thanks in advance.
