So I tried running a k&N filter where the oil cap goes and got oil everywhere, I need some sort of a serious baffled system. What do you guys use, I don't have a dry sump. I also refuse to use the PCV long story short, tried a catch can + ls6 valley.

How about using another drivers side valve cover on the pass side?

 

Go to the tpis website and check out ls-1/ls-2 oil components,they have a well thought out system that works! it is not just a hollow tank with fittings, the tank is built there and has internal baffeling that keeps the oil vapor from being pulled into the engine I have had the system on my Camaro for 2 years and my intake is dryer than a popcorn fart.
