I have a set of gm covers on my vortec heads. There are four holes in the covers for stuff, one will be Pcv, one will be for oil...but do they sell breathers for the 1" hole on the cover? I'm just looking for one breather, K&N or anythng t put into the other pcv size hole...It's not 1.25...anyone have this problem?

Found a chrome/red filter one at Autozone that fit perfect. It's in the R*I*C*E section, but works like all the others..
