On a side note, pan evac is a little better than a vented catch can simply because it pulls vacuum on the crank case...
Ok so I have read this through a few times and I think I understand most of it but im unsure what exactly pan evac is and how one would go about specifically doing this. Is pan evac when you vent the valve cover into the exhaust using the venturi set up?
Am I correct in saying: pan evac (venting into exhaust using the venturi set up?) > breather tank > baffled catch can rerouted to intake > no catch can
Also some members have been referring to needing to mount the venturi tube at the "right angle" in the exhaust....so what exactly is the right angle? Lastly how does one exactly go about creating a correct venturi tube ie shape, tube side, length?
I was going to do a simple catch can set up but I am intrigued by the idea of simply venting into the exhaust or near the turbo to be burned off. The turbo and exhaust are currently off so now would be the time to do it.
Last question, if I were to run two large lines (say -AN12) from the valve cover to the exhaust do I still need the little nipple on the valve cover that has a line going to the manifold?
