Distributor Help

I recently changed the cap,rotor,spark plugs and wires and now there's a noise coming from inside the distributor. it sounds like some kind of rattling in side of there. it didnt do it before i did the tune-up. any help???

the cars an 96' integra gsr

Is it running ok? Did the rotor set screw tighten all the way? I'd take the cap off and look for any signs of marks on the rotor or cap at least. Is there a dust cap or shield under the rotor? Make sure it's in it's place properly!

the car is running fine. just when im stopped i can hear the distributor. the screw is on tightly.
im gonna check the dust cover to make sure its in place but thnx for the advice
