Within the last week ive installed a CAI, catch can, and now a breather in my oil cap. I plugged both ends of the clean side PCV. Im 99% sure everythings good but just wanted everyone to check my work first.

i could be wrong but plugging things up might lead to increased pressure and leaks

The breather on the oil cap is supposed to prevent any pressure build up.

But many user's have had problems with oil trying to blow through the breather and many switched back to the original system or installed 2 catch cans- a "dirty" side (where yours is) and another on the "clean" side (where you capped off).

Hopefully you won't have that issue and BTW- your work looks great!
Enjoy the music of your new cold air intake...

That catchcan is an empty container and will do zero to stop the oil you want stopped. (take one of the allen screws out that holds a fitting on and look in w/flashlight...nothing inside!). Then the breather will result in un-metered air entering so your short term fuel trims will go nuts. Far better to use a cleanside separator like the Elite unit for $99 that retains a closed systems for emissions, stops the oil on the cleanside, and does not mess with fuel trims. I would strongly suggest you get a can that actually will stop most of that oil ingestion like my favorite, the Elite Engineering or similar.
