Deciding on a/which catch can(s)

Deciding on a/which catch can(s) currently i am running N/A and after a few years i have noticed a TON of oil mist bellowing out of my valve cover breather. My tuner had deleted the pcv system in favor for a valve cover breather. at first i had no issues with it but as time goes by it seems to be smoking more and more. maybe something is wrong with my motor? bad rings? tons of blowby?? i dont know but after long rides on hot days my engine bay will be soaked in oil mist and buildup. I am going to be building a whole new motor and going turbo soon so would like to have this problem solved and useable on my current NA setup and reuse it on a FI set up.
im liking the MightyMouse set up but i need some explanation on how it works?? he has a breather on his so does it actually pull a vacuum or is it simply a vented air/oil separator?
i really want to pull a vacuum as i believe thats how these engines were intended to operate so im not a fan of just open air venting. i also want to avoid having to run an add on vacuum pump so how can this be done when going FI? can i route to the intake side of the turbo to pull a vacuum? will that be too much and risky of pulling oil in though the turbo?
dual or single catch cans? i definitely want something that will actually do its job that is built right with baffles and not mesh (which gets saturated) and will properly capture the oil mist and keep it from getting sucked back into the motor.

Not exactly sure if this answers your question, but the only time I ever had any blow by was when I hurt two pistons. Up until then and every since I fixed the pistons I've been good. If your oil is getting dirty real fast my guess is that something is hurt and the catch still wont solve your problem. Just my opinion though.

as for the catch can im just wondering which one to get to hide the issue for the time being until i build up a new motor for boost.

my pcv and draft cans top breather is one gimongus one way check valve. pressurized fumes exit freely when they exist; seals for pcv or draft operation when they do not.
anyone that has come to me looking to fix a blow by problem i always reccommend making sure the engine is healthy first before spending money on a can when you need rings or pistons
