Finally did my breather bypass (pics included)

Okay, been through all 46 pages...as well as several other threads and have yet to see the idea I had. makes me think there's a reason for that that I may be missing. The look of the DK system with the catch can hanging straight down is growing on me though. I just don't like the looks of the set ups with the hoses running down through everything. Not to say they don't work just not my cup of tea visually.
My take was a small modification on one of the ways a few have gone. I wanted to tap into the "top" of the SE Hi-flow standoffs. Think 2 and 10 o'clock-ish, run two small pieces of hose to a duel input breather filter placed just above the TB.
By the end of a season I get enough oil accumulated in the bottom of the A/C that you can tell it's there when you take it off for cleaning but none ever drips. I'm more interested with not sending the hot exhaust gases back through with the added benefit of removing the small amount of oil that is getting in there. I was figuring that at that short of a distance with a definitive slope back the small amount of oil I am getting would drain back to whence it came.
So, since I haven't seen anyone else go this route. What am i missing?

If I understand what you are suggesting, there is no down hill draining in your proposed set-up. It's all up hill and terminates at a high spot. I would think your "definitive slope back" would eventually fill with oil, and block the venting... not good....
Look at a this pic of the heads. The blow-by mist follows the marked passage, from the one-way umbrella valves, and drops to a low spot where the breather screws attach to the head. Any condensed oil can't drain back to the engine from the breather screws (or "SE high flow stand offs"), it needs to go downhill from there....

Never a problem here and I'm one of those that keep a "to the full" oil tank and ride pretty hard and engine brake coming down the mountains.
I gotta laugh at my own analogy here but oil blow by is like always shittin in your underwear. you can wear a kotex to hide it but theres a problem inside somewhere that needs attention.

There's pressure in the crankcase caused by combustion gases going past the piston rings. The stock set up brings those gases back into the throttle body to be burned rather than put back into the atmosphere which the EPA doesn't want. It's called "positive crankcase ventilation" or PCV.
