Vacuu source for catch can/pcv on a tc78 So question for everyone. I'm trying to figure out where to draw a vacuum for my catch can/PVC system. I see most reference it off of the turbo compressor side, but does that mean using the existing 1/8th npt port on the compressor itself or taping the filter pre turbo? If you go off of te existing port wouldnt that also pressurize under boost? Checkvalve maybe? Any pics you guys got would be good.
I just drilled the side of my Kn&n filter and fit a brass 3/8th double barbed connector into the filter. The other end comes from my passenger side valve cover.
Here is a diagram, and you should read this thread, it has a ton of great info. https://ls1tech.com/forums/generatio...outing-ok.html

Thanks, that answers my question. I've been through that thread, I just wasn't sure exactly where you guys were sourcing the vacuum. What k&n filter are you using? I have a 4" one, but it's too tall and I'll need to get a lower profile one.
