PCV hose diameter?

[QCV8eater]

As title says, what size is the PCV valve? I'm being asked this question to buy a catch can and since Ican't go check because it's in a garage behind a few feet high snow...
So... any help would be apprecited!

BTW... You ppl who have an oil catch can... Where did you mount it?

Thanks

I'm pretty sure I used 3/8" hose on mine. And I mounted my catch can on one of my 1G BOV flange bolts. I've also seen them attached to one of the valve cover bolts.
