PCV and crankcase breather vent
Just to be clear, I'm not losing oil by the breather filter. I'm losing oil it seems around my OIL filter. Are you saying because I installed a breather filter, that it creates much more pressure in the crankcase, enough to force oil out from the block by the OIL filter area? I'm not sure if we're on the same page! 
Sorry for asking again, but I want to make sure this is the culprit.

nevermind, we definitely werent on the same page...i thought it was leaking from the breather filter area
so could it be from the fitting you installed?

Haha, actually yeah I did blow through them. Of course there is back pressure, but I don't think it's enough to cuase an issue, but then again, I'm trying to learn more about this system, so I guess I would REALLY know.

After one day of driving (40+ miles) I only had VERY VERY slight oilly film from the valve cover to filter (I'm using clear tube). Filter to intake was clean as can be. We'll see how long that last

and like i said before its not the "ideal" way to do it, but on a budget (or if you dont have the means to make a catch can yourself) it will work
I thought I was losing my mind after reading your responses!
lol! The strange thing is, I haven't touched the fitting for the oil temp sender, nor the oil filter (since the last oil change). Only thing I changed was adding the intake and breather filter on the valve cover....Maybe it's just a coinicidence then?

could be, but a lot of the times they arent coincidences...get under there with a light and see where its coming from

yep, thats exactly what happened when i ran that setup, it will work, but youll need to change the filter every so often, it will get clogged pretty quickly

I'm going to see how two back to back fuel filters do in the PCV line. Probably like 1 week, but we'll see... it's worth a shot.
Thats why the mitsu engineeers designed the IC plumbing the way it is - so the warranty would be expired by the time all that oil and sludge makes it's way to the throttle body (130,000 miles)
ahhhhh no
When the motor is running vacuum, both fittings are trying to draw a vacuum, hence kind of “fighting” each other. When in boost, the PCV valve is shut, and the port leading into the intake is still under vacuum because it’s pre-turbo. So, they are no longer fighting each other. Hence, the port leading into the intake is ALWAYS under vacuum. Now, my theory is that if I put a breather filter onto where the PCV used to connect, there will always be a vacuum being pulled across the manifold because I will still have the connection leading to the intake, where there is always vacuum. Seems to me like there will always be a “draft” of clean outside air running through the valvetrain cover because the intake is always pulling vacuum, and it also doesn’t appear to be a “emissions” problem because the gasses that are evacuated from the valvetrain cover will still be run through the motor, and burned off.
Hope all of this helps….
Ummmm, yes...
It doesn't matter whether one side has more than the other, they are still fighting eachother because both sides are in vacuum. Because one side has more than the other, well, it wins the battle easily. Because there is still a vacuum on the intake side (Even though it's very small, in contrast to the PCV side of things), you can use it.

Here are some pics of my "set-up" :P
Breather to intake
PCV... I used to filters back to back. This is only 20 miles worth of driving to and from work. Very light out of boost driving 90% of the time.
Filter #1
Filter #2 (not much, just very small deposits)
Now, I understand this system I have with fuel filters for the PCV isn't exactly the best. FAR from the best. But, until I can afford a DC3, this will do. It's better than nothing.
So far the filter on the breather between the valve cover and intake seems to be working great. I think with the small amaount of vapors that travel through there, the fuel filter will do just fine for now.
