How loud is the noise? Is it possible for you to make a video recording of the engine idling making the noise and post it here so I can view and hear the noise? If I can hear the noise, I'll be able to tell what you will need to do first...

If you can make a video, let me know and if you can post it to YouTube and post a link here so I can view it, It will help greatly...
