a continuation of
viewtopic.php?t=39868 but i figured i would open another thread since this is a specific question about this product and if it would work.
While it is pricey... i think i like a see through better than a Provent. I was thinking about venting the other side down to the frame. Any ideas / concerns about this before i order?

Hello, Ribbon,
Are you referring to the segment of hose between the PCV valve and the filter? This is normally under vacuum and as the filter gets "dirty" vacuum pressure in this area will be reduced. Upon wide open throttle flow can actually reverse so that blowby gasses exit the fresh air intake (typically on the driver's side of the engine). I would surmise that if the filter were severely clogged, positive pressure could be created in the aforementioned area, but to be honest with you, I have never measured positive pressure there. You do have a couple of options, though. McMaster-Carr sells an adjustable pressure relief valve that can relieve vacuum or positive pressure. It costs less than $10 and can be teed into the catch can on the PCV side. It is part number 48935K25 in

The other option is to add a tee to the catch can to allow you to check vacuum pressure at idle, using a simple vacuum gauge. The gauge port can be plugged until ready to use. I generally check mine every 5000 miles. As a rule of thumb, a drop of 10% vacuum pressure means it's time to change the filter. For most cars, that would be about 2 inches of mercury or approx. 18"Hg vacuum pressure.
Please let me know if I can be of further assistance.

The provent is an oil separator with a pressure relieve , and it drains from under the jeep when you do your oil change. Look online for good video of how it works.
The glass one is a simple "catch can" that will get half of the oil.......maybe.
