So as was posted earlier the inner diameter of the delrin bushing is just barely slightly larger than the metal tube on the inside.
The annoying noises I was hearing were caused by
A)my filter falling off (fixed) and
B)The metal tube rattling around inside the bushing during idle
So I took out the mount, and placed a small strip of duct tape on the outside of the metal tube then shoved the tube back in. Its in there REALLY snug now, wasn't moving at all.
The difference this made is indescribable. Rattles, clunks, AND the vibrations all pretty much disappeared. Its barely worse than stock while idling. And while driving, there are pretty much NO vibrations now.
So while the duct tape "mod" is an example of ghetto engineering, I really just did it to see if it would make a difference to have the tube stop rattling around. Now that its so much better, I think I am going to redo it again, but use some sort of epoxy or something other than duct tape.
If you are having similar issues to what I described, give this a try.
