I appreciate your concern Donny, I'm learning about all of this from scratch and every bit helps. I know what I had before did not work...and have a pretty good idea why. If I'm correct in that assumption, this should cure my ills.

If there is enough flow for the pressure to exit the driver's side breather to the catch can, why would its need to exit the pass side also?

I'm not sure why it would suck more oil under that scenario? Foul blow by air is one thing...that needs to leave the crankcase. Extra oil with that blow by is another. David mentioned that something his LS customers that road race deal with is the oil that builds up on top of the head during a long straight at WOT sloshing over the baffle and being blown or sucked into the line to the catch can under hard braking at the end of said straight. This symptom can fill a catch can up during just one session on track.
He doesn't think I'll have that issue because of the extra height from my tall valve covers, we'll see though. That is why I'll have the recirculator top to put on the can with me along with a line ran to a second can if needed.

Not an issue, it can be removed without any tools at all...if needed.
