Venturi vacuum pump

[HiImBrian]

Well I just re-read this thread twice and I don't think I've learned so much at one time before! I vote this most informative thread on style for quite a while. I would like to clear a few things up for other newbs including myself in this situation.

The first pic is of somebody with just a filter on their vc. This is bad because it allows air to get sucked back into the vc.

The second pic is a setup with a simple catchcan/filter that goes on the line from the vc to the intake.

My understanding of the Krank Vents is that one goes on by your pcv valve and acts as a backup making sure no air gets into the vc, and the other goes on a line from the vc to the intake sucking some air out but again not letting air back in. You would also want to use a catchcan/filter on the line going from your vc to your intake.

I'd appreciate it if somebody could edit my post and correct anything that's incorrect. It may be a little late for this post, but I'd like to think I'm helping out some future newbs we might direct to this thread.
