I run a 3" wide 2" tall K&N and im blowing oil OUT of that filter..unreal
this is with a catch can vented from the valley as well. Is there any other set ups that are good for a vacuum pump other than GZ? 800$ is a bit rough

If your getting oil blown by through the breather, your getting too much pressure inside the engine.. Piston ring blow by.(?).. and you have to evaculate the pressure.. a PCV system with a Oil Catch Can or a Vacuum pump with a catch can will be needed.
Just adding a breather to a engine is not always the correct thing to do.. you really have to build the system around a breather. You need to using a vacuum source (intake vacuum or a pump) and some means of filtering out the oil from the pressure/vapors (PCV valve or a catch can).
Adding a breather may look cool... but it may not be the best thing to do if incorrectly done. There is some advantage to using a close system with a good vacuum source.. it can benefit the sealing of the rings.. many pro race engine setups use evaculation system (pump, catch can, breather, etc), but as a completely designed system.

I have a K N breather on the Left valve cover. Then on the Oil cap ( R valve cover ), I drilled a 3.8 hole. Then I glued a 3.8 piece of fuel line in there with a flare on the bottom. Then I attached a 3/8" hose from there to a catch can. ( Old A/C Accumulator under the front bumper ). The inlet on the catch can is close to the bottom. Then the Exit ( PCV Inlet ) is close to the top. That connects to my TB and so far NO oil has entered the TB that I can see. I'll know for sure when I do a cam change and a stage 2 port on the LS7 heads.
I was using a small catch can but it was worthless !
Some guys say run No PCV, but in order to keep condensation down, you need some sort of ventilation in the crankcase. If not, Condensation will build up .
