Thats my old evo. It seemed like a nice setup, but I don't think my evo ever made enough power to really test it. No real good way to hide the lines, I eventually zip tied the lines together and that gave it a bit more of a "cleaned up" look to it.
On my black car I had 2 -10 lines in the stock breather spots going to a vented jmf catch can. The valve cover also didn't have baffels so it wasn't the most daily friendly setup as you had to drain it a lot. You could always do like some people do, put a fitting into the hole on the block to check to see if you balance shaft is set correctly. I've read of Honda's doing this but don't think I've ever really seen a dsm do it. I'd save you from having to drain it ever. I think the -10 lines look cool in the engine bays if you have a cool catch can too.
Old setup in the black car. If I ever start to make more power I will go this route again I think and try and re-attach the baffle. This setup cured shooting my dipstick sky high.
I'll be interested to see what you end up with.
