Clicking, but no RI

So, for the last 7-8 months I've been noticing my ball python clicks every now and then. I've checked his mouth throughout, absolutely no sign of an RI. Over the course of those 7-8 months it hasn't got any worse, or any better. It doesn't happen every time he breathes and there's no mucus in his throat.

Should I not worry? He's perfectly healthy other than the occasional click.

Probably just some frustration noises. Some of my snakes will make a noise when I disturb them or try to pry them off of something that they have decided to wrap around while cleaning their tubs lol. If it's eating well and acting normal then no problem :)
