I seen all the post about the catch cans etc. Seems like they all talk about the filtered catch cans. My question is this, wouldnt running a closed catch can "Greddy" from the PCV to the Manifold "just like splitting the PCV line but running it into a catch can" clean some oil/vapors? Anything wrong with running this setup? Shouldnt this just allow cleaner air into the intake manifold?

 

info?

 

these are my thoughs also, im about to do this. This way keeps the stock indended vacume levels on the crank case. maybe more really high HP setups u cld plug from the back on the block, but u should still have a vacume source to draw windage postive pressure out of the crank case

the one of the valve cover is just a fresh air inlet, u can do what u want with that. Maybe for high HP they need more air rushing in so tap another hole.
