There's one thing I just noticed Chris that contradicts what I've heard in the past. I've always understood that you don't want to place a check valve inline between the VC and the intake pipe. Leaving that line open should better help ventilate the dirty blow-by air out, by not only allowing the old air to go out the PCV line, but by also allowing fresh air from the intake in. By putting one in line with the Intake & VC, I understand that at idle you'll create a much stronger vacuum under idling or low throttle conditions, but I don't understand the benefit of that. It wouldn't ventilate the dirty blowby air out of there as well as if you had the open line allowing in fresh air. That dirty air is bad for the oil, and you want to get that out of there as quickly as possible. If it's creating excessive vacuum at idle, enough that it's actually difficult to remove your dipstick, that seems like it may actually be bad. My CCV system is one of the little things I was going to improve upon this summer, so I actually read up a bit on this subject not too long ago. But my plan only involved using a check valve (as a back up to the PCV) between the VC and the IM. Here's a nice little MS Paint version of what I planned on doing to give a visual idea, using 2 catch cans.
