Can you plumb a PVC valve through the intake manifold into the lifter valley, and keep your valve covers vent-less? As Ron61 said the pre PVC equipped engines had a pipe exiting the manifold and dumnping into the atmosphere. So, I'm wondering if I could drill through the manifold in an area that leads to the lifter valley, and plump the PVC from there. Is the lifter valley equalized atomspherically to the crankcase?

I got a nice new set of cast valve covers with no holes, and like the way they look. I really don't want to drill into them.

Thanks, Mike
