Valve above expansion tank is leaking


So I came home today and my garage smelled a little funny. I went and checked out the boiler and it was wet under m expansion tank. There is this tube shaped piece with a valve on top that is about the size of a tire stem valve. It looks like it leaking out of that. The screw on top was not tight but either way if I tightened it or not it still leaking a little. I did not leave it tight because it was not tight when I looked at it at first. It's not a nut but more like an aircap but with a hole it in. Please see pictures. So my concern is do I need someone to come fix this right away? Can I fix it myself? Why is it doing it? etc. The pressure on my boiler never goes over 20psi.

Here are some pictures

Its an air vent. Dirt has gotten to it. You an replace it yourself. Need to reduce boiler pressure to zero to do it.
