During the course of doing a HG replacement I broke the old BVSV breaking it down and I broke the new one putting it back together (yes, I know I am a Dumbass). I think I understand what this valve does. How critical is this valve and can I get by without for the time being (winter time and all). If I just install it with no vacuum lines hooked to it? Why would they design this part with the tips so easy to break off? (rhetorrical question)

If this is the BVSV that runs the canister purge it should be fine without it. IIRC it is just to control evaporation emmisions when parked. However, I would block off the ports to help ensure you don't end up with vacuum leak.

I am not sure about the V6, but on a 22R there is a BVSV controls the EGR. Running without the EGR will cause pinging. If you are not going to get a good BVSV, then you would probably be better off attaching the hoses together so the EGR works all the time instead of not at all.

Edit: I just looked up the 3vze manual on Autozone.com and I noticed that the BVSV controls flow to the charcoal canister like BC_Rider said. He is right, just plug the vacuum line and you will be fine.
