Theoretical: AOS delete on non-dry sump
If one needed more space in the engine bay and the oil filler neck was in the way and decided to remove the AOS and plug the block, what would be a solution to keep the crankcase vented? Filling oil could be done through the cam tower ports. Would a LR Breather tank work on its own, or could a $5 GM PCV be made to work?

I would vote for the PCV conversion. Maybe use the top AOS port to stick in a PCV?
I haven't looked at the LR breather kit to know for sure where it mounts, or how it works, but as long as you're pulling vacuum from the crankcase, anything will work.

Ok then, I guess I might give it a try unless someone can give me some reason why not to do it.
This would be for my supercharger. Today after cutting up manifolds and stuff I found that my A/W intercooler at the right position relative to where my cutoff runners will be will need to go where the AOS is for one corner. It's a big unit.
My AOS has been leaking a bit anyways so maybe I'll put some large allen plugs in the holes instead.
Since it needs to be a vacuum system I think I'll use a generic PCV valve with a hose plumbed from the upper AOS hole to somewhere before the SC intake point. This will mean I will get oil on my rotors but hey maybe it will cool them down or something.
Isn't that how it's done on the turbo models anyways? Oil vapor hits intake just before the turbine?

We have a kit under production. All CNC:ed parts are more or less finished. I hope i can put here some pictures during this week.I needed space for my bigger plenum, so i needed this kit myself.
I suppose these items will be available also in the USA via a Rennlist suporter.
This might not be a good idea, from lower port there is a tube which routes oil directly to the oil pan.From upper port it's at least slower. We use both ports in our kit, lower for oil and upper for breathing, just like the original system does.

actually im planning on machining a plug for the bottom port and fab up some smaller fill tube for the top port

Don't bother with the Lindsey can. Use a Saikou Michi dual catch can, one venting from the top of the AOS and also the cam tower, the second can comes from the lower port. Both cans pull vacuum from the intake before the turbo. You may need to add a breath or PVC inline on the cam tower or the lower port if too much vacuum is being pulled.

think this would be an effective setup? i like to visualize things lol.
breather tube picks up before AFM and goes to the upper AOS hole, and then the vapors would come out one of the cam tower plugs to the PCV just after the throttle.
