take a look at this link. The second picture with the with pcv going to catch can and top right vc nipple going to catch can. Is that incorrect? If i did that i would need to plug the nipple on the intake manifold where the pcv hose would usally go

s132nr that picture of one of ashton's setups is not right.

The way he did this isn't optimal, however it made sense for him because he didn't have a PCV provision on that intake manifold and his car is mostly a drag car, so he's not especially concerned with partial throttle crank case scavenging.

There are much better ways to do it.

That way it's done in that picture basically everything is vented to atmosphere.

Yes. Assuming I'm imaging the same catch can that you have.
Here's the general idea with pics

Yes. That's the idea. That's the way it is from the factory. You don't want to alter the way things are from the factory, except to strategically put catch cans in the pathway of some of the lines.

It couldn't hurt to lightly pack the thing with steel wool if it seems to lack in baffles and perforated sections.
