i have aftermarket aluminum valve covers on my BBC, each cover has a twist on type hole with baffles,after searching on the forum i want to install the pcv utilizing one of the twist on holes. does anyone know were i can get a grommet for one of the twist on holes that will accept a pvc valve? or is there something else i can do?

TIA
Bill

I'd think any of those one inch grommets would work,,,just push it in there.
