For long term use , its important to use a catch can that allows the gasses to be sucked into the intake .

Intresting article, I have always liked the design of this can 034motorsport sells https://store.034motorsport.com/catch-can-vortex-breather-universal.html it creates a center fugue effect that helps remove oil from the air but let's the gasses through. Keeping the oil out of the air tract is extremely important for engines with intercoolers. The ones that vent out don't make sense to me because you are using crankcase pressure to force the contaminations out instead of pulling them out and burning them, while keeping the intake tract free of octane robbing engine oil.
