need to vent crank case pressure !!
These things don't have a pcv valve. Just a straight hose to the intake tube. Imo if you have more pcv pressure then that tube can handle then you have more issues at hand. Esp with the vaccum the intake is under under boost.
I cracked a diamond piston ringland last year and it popped the dipstick up.

I have one of ^^^ but have been looking into this idea.

But I want to run it in the extra O2 bung installed in my ZZP cat-d dp.
It would be the bung after the cat.

Do you think i would be able to produce enough vacuum to pull the valve cover gases out without using the weld in fitting?

To run this properly you'll need to it vent to a dump or open header to eliminate positive pressure causing the exhaust gases to shoot back into the valve cover.
You will also have to purchase another item from jegs that adjust vacuum. Can't remember what it was called for the life of me
I ran the EXHAUST EVAC with lack luster result

Tis why I said open header required :/ Stupid check valve cost me $50 to find out it won't work unless I run it with a dumped exhaust :/
Oh! I know what your talking about...the orfice tube.
Hm....a positive system.
Per alldata.
Crankcase Ventilation System Description
General Description
A crankcase ventilation system is used to consume crankcase vapors in the combustion process instead of venting them to atmosphere. Fresh air from the intake system is supplied to the crankcase, mixed with blow by gases and then passed through a calibrated orifice into the intake manifold.
(Pic here)
The primary control is through the positive crankcase ventilation (PCV) orifice which meters the flow at a rate depending on inlet vacuum. The PCV orifice is an integral part of the camshaft cover. If abnormal operating conditions occur, the system is designed to allow excessive amounts of blow by gases to back flow through the crankcase vent into the intake system to be consumed by normal combustion.
Results of Incorrect Operation
A plugged orifice may cause the following conditions:
Rough idle
Stalling or slow idle speed
Oil leaks
Sludge in engine
A leaking orifice may cause the following conditions:
Rough idle
Stalling
High idle speed

according to moroso if you have less then 1lb of back pressure it will work you can also change the angle of the weld in tube to create more vaccum pull also
Makes sense to put it there...so it'll put the vented gases directly into the intake ports vs sucking them into intake tube before the throttle body caking it and the intake mani up with gunk!
It can pull air across the valve cover and into the intake with this set-up.
I made a breather with a pop-off valve in it so that it's only open when the crankcase is in positive pressure.. Kinda felt like a genius...
it can still do that you have a breather coming out of the back vlve cover
My greddy catch can just came in yesterday....
WARNING!!!
Biggest waste of $140 shipped... cheapest i could find it btw
its a metal can with zero baffling, does not have a drain... so you need to undo one of the fittings to drain it.
WTF... PEOPLE RUN THIS ****? AND EXPECT IT TO DO SOMETHING?!
carry on
