New noise in the bell housing

[Summit A]

While i was attempting to take a little play out of the clutch pedal on my 29 I found the clutch arm nice and tight. In the process of reconnecting to the pedal, it became a little loose with some movement that wasn't there when i started
Now when driving i hear a rattle like sound that sounds like its in the clutch area? Still drives and shifts but now i wonder if its safe to drive. Or what i may have screwed up. Thoughts? Thanks!
