EPS discontinued their pcv breather kit, heres a video I found as alternative

If I ever find a simple way of separation I might be willing to try it.

Z1 has a 4D cad milling machine (they use it for porting lower intake manifolds and prototyping) - I saw them milling a plastic copy of a LIM at ZNats.
I think they are friction-stir welded by the manufacturer - nylon based plastic probably won't do well with solvent-based glue. To me, they look like the runners and horns are attached to the bottom - the top just seals off the plenums on either side; there's cross-over between both sides but it's chaotic (IE not an airflow passage but just space between the castings).

@BULL about a 10-20k mile update idk how long its been a while lol, tons of blowby on the driver side!!! im so happy with how well the ebay system works! The passenger side had like nothing though, is this normal or should I look into it?

During my first check around 1,700 miles the driver side and passenger banks had caught the same amount. After checking again around 3,500 miles the passenger side was basically the same but the driver side had a lot more. I didn’t measure exactly how much but seems to match your results.

I also wonder then if it could be that you're having pcv issues. We're they new pcv valves?
Monitor both cans during oil changes, see if you can dump some carb cleaner through the pcv holes to see if it's dirty pcv gallery inside the intake manifold.

I suggest for both of you to run a full can of carb/brake clean through the ports in the Manifold to discard as many variables as possible.
Lastly would be to determine if breather design has anything to do with can collection.
Pre conclusion: being that the VHR does not use a balance tube like the DE or HR might be the reason why the unevenness. Unless the breather plays any effect then it would solely reflect the vapors that each bank typically sees. They only share the timing cover area and once these lighter/hotter gasses leave the crankcase, they wont mix once they're in the head.
Thanks for the data guys!

There has also been reports of levels being different between both cans.

pcv valves were new, and gutted by yours truly (me, bread, and myself bread)
breather position might have something to do with it, or maybe position of the cans are either "too high" or in a location where it stays consistently hot so it doesnt have time to turn from vapor into liquid.
i didnt take a photo of my gunk cause i was in a rush, though its stored in a plastic bottle, and i was very much impressed by my ghetto ebay work!
will keep updated

Anyone have pics of the underside of the valve covers? It the PCV hole just open to the entire area, or is it shrouded in any way that could be different between the sides?
So... with the VHR they went to separate PCV breather systems vs the single vac port the HR has. I doubt packaging or cost reduction had much to do with it, so... what is the advantage? If we can know that, then we could determine what goes potentially down the hill if we incorporate a balance tube for the VHR.

I know back in the day DEs were common to clog PCV canals and when changing VCs when doing gaskets it would improve MPGs due to better flowing PCV

@bull update # idek anymore
you said use carb cleaner in the pcv valves, is this safe to do on the motor?
also, with doing my oil change, and its been like 3500 miles, i havent seen any signs of oil in the catch cans. I cleaned my filters too (lots of super clean and soapy water, then ran through it until it came out clear)
My catch cans are near dry, just very thin coat on the bottom.
Previous oil:
Liquimoly supertech
New Oil:
Mobil 1 Ext Perf. High Mile.
Also following this thread too:
