I have a 30 years old EEb Mirafone with the old style S links. It's eerily quiet. A while ago I did notice some noise from one of the valves. I checked everything outside and still had it. After reading archived threads here I decided to try the adjusting screw on the bottom of the valve. I put a tiny screwdriver in the slot and breathed hard on it. Worked great. Been quiet ever since. I'll second the notion in another post that it doesn't take much to tighten the screws too much. Be gentle.
Good luck
