Hi Guys' so it's time for another project! When this engine was on the dyno with the PVC plugged, it had a small amount of crankcase pressure. The rings weren't fully seated so we put a set of really ugly chrome Moroso air cleaner style breathers in the engine, no crankcase pressure. The breathers that are in the photos are 440 Source billet units that my friend Tony Dunlop at the shop re-sculpted and we anodized black. I like the appearance of them but you can hardly blow through them, I sampled some different breathers (very scientifically, I blew through them) and decided that those were very restrictive compared to all of the others I checked. In addition to them being restrictive, the breathers also passed a small amount of oil mist and made a mess on top of the valve covers. The valve covers have no baffles at the breather holes and in my experience with-out baffling they will pass mist oil. I don't like the idea of bolt-in baffles and if we welded them in it would require re-powder coating the valve covers. Trying to keep the engine bay neat in appearance I decided that remote breathers were not an attractive option and that possibly I could design and build breathers that would meet the requirements.
You do have to understand that this is the part of the car hobby that I enjoy and I do realize that most of my friends (and other people) think I'm a nutty. khryslerkid thought I should show more in-process information so here's to you.
My thoughts were to build a larger breather with labyrinth baffles inside in an effort to remove the oil from the exiting air. An outer chamber would contain filter foam to reduce the possibility of in-taking debris. This is what I came up with, what's your prediction do you think it will work?

My concept is that the outer components contain an inner labyrinth "cartridge" that can be changed if it doesn't perform well.
