My new valve cover crankcase vent setup. Thoughts/opinions needed.

You don't need to put steel wool in, it has a maze of baffles to seperate the oil,

And it does a very shitte job IMO...It wouldnt hurt anything putting it almost right before the hole?

You could try that, but its very tight in there and you could end up blocking flow.

how is this set up treating you Simon?

Not using it right now, trying to figure out how to redo it, I just filled my catch can in a week,

Fixed. For some reason, PB changed their IMG tags,

Sorry to necro this thread, but I'm in the midst of figuring out a new breather system for the Spirit, and I was wondering how the valve cover baffles have been working out for you, Simon. If I'm getting the gist correctly, it looks like you've essentially built a box around the vent fitting, leaving open some holes around the perimeter for excess pressure to escape. I was thinking of doing something similar, but instead of leaving holes around the bottom, I would drill holes on the vertical side of the box (i.e. the bit that's perpendicular to the top of the valve cover).

I am using 1/2" female NPT fittings in the head so that I can use brass hose barbs and rubber hoses for now, moving up to AN fittings and braided lines when/if required. The "box" will probably be able to fit around this just fine, but I am curious what the maximum height the box can be without interfering with the valvetrain. Has to be pretty shallow, it looks like from the pics?

I am actually not using it, with a good engine, I simply used the stock block location, lengthed the hose to the factory seperator box, then to a catch can. Worked great until the ring seal went then I started filling up the can in no time. Without the factory breather, I was emptying the can every couple weeks, with the breather, almost never, but make sure the breather sits higher than the block fitting.

Correct on the valve cover, just made a box at one end and left it slightly open, it did work every well when I used it.

Looks pretty good. I plan on welding a -an fitting to each valve cover and bringing them together into a custom catch can and routing it back to the oil pan so I never have to change it. Rick Diogo has something like what you have there, heres a pic

Not sure if thats a good idea. Catch cans also suck in blow by gasses that mix with your oil. Pitting contaminated oil back into the engine is a silly thing even if you run fancy diesel oil like me (somewhat resistant against contaminants )
