Replacing PCV valve in a 2012 Civic?

When replacing the PCV valve in a 2012 Honda Civic, is there any potential for oil to leak out while replacing it?

Not sure if I can just unscrew the PCV and replace it, or if I need to do some sort of prep beforehand to prevent oil from escaping?

Nope simple procedure. Could drop your gas mileage though.

Nope, no oil will pour out. The valve itself will have oil on it though
