PVC
does it matter which hole in the rocker cover the PVC valve goes in? baffled or no baffle? I want to put my filtered breather in the baffled hole.
DO we really need to have a PVC system hooked up to the motor? what happend if I remove the PVC and just plug the hole in the plenum?

Re: PVC
The PCV valve goes in a baffled hole to keep it from ingesting oil.
You don't need a PCV system, but you really want one.

Re: PVC
ok so what will happen if I plug the hole under the plenum and just put a cap over the hole in the rocker cover?

Re: PVC
You'll vent vapours out the breather, and you'll have increased oil contamination.
