    so i bought a new pair of valve covers for my 302 the other day. a real nice set of polished aluminum from summit racing.
    just opened the box and noticed that it has no breather holes drilled. does come with the baffoled and a pre marked area for the hole though.

    question is, does anyone know what exact size hole needs to be drilled into the valvecover for the gromet to the breather cap?

    usually on the underside there is a line mark to where to make the hole.

    when you get the grommet, it should tell you what size hole it fits...:yup:

    PCV grommets come in many sizes. Get the PCV valve that you want first then get the gromment
