Default Ratcheting noise from the gas cap

My 2003 Disco is making a ratcheting noise from the gas cap...it sounds like a very rhythmic, loud and persistant cricket. I'm guessing that it's sucking in air? Does anyone have any ideas about what or why? Thanks!

When is it doing this? All the time, when driving, when stopped?

It sounds like you may need to replace the gas cap. If so, this is what you need: http://www.roverparts.com/Parts/WLD500100G.cfm

I hear the sound most when driving. The faster I'm going, the faster the sound. If I am stopped I hardly hear it at all.

You sure it's the gas cap? The front drive shaft also chirps before the u joints break apart.

Makes the noise even if I'm parked, it's just at longer intervals between chirps, and just replaced the u joints so I'm pretty sure it's not them, although just you saying that made me feel a little nauseous, Bundu.

The sound is definitely coming from the gas cap.

OK... just checking with the drive shaft.
Get a new gas cap, it is made by Stant and my local Walmart had one.
