I have 2 greddy style catch cans, what kind of element do you guys suggest I put in them? I'm weary of putting stainless steel wool inside of them because it might break up and get sucked into the engine.

Catchcans experience a drop in pressure, but I don't believe that vapor is "rushing" through them. I would be more weary of steel wool because water moisture will cause it to oxidize and turn to junk.
I would also avoid copper wool because it acts as a catalyst to oil and it sludges up in your catch can.

That is one thing I have wondered about, but I have worried about the temps of the oil vapor.
I like the idea of stainless mesh because it holds its shape and doesn't bunch up like softer materials such as green scotchbrite pads, and loofahs
It is important to keep whatever you put in a catchcan loose. If it bunches up, then it blocks the path of the oil vapor and defeats the normal function of the PCV system.

In reference to using the air compressor filter setups like this:

http://www.pbase.com/rsrock/oil_catch_can

Can I just buy two of those and the appropriate fittings and just run them inline between PCV/turbo inlet and crank case/inlet? Is it really necessary to run more lines around the engine bay? I would just like to cut the correct amount from the current lines and run these little filters inline to catch the oil. Please let me know if this would be a wise course of action.

As a filter element i used a lawnmower air filter. Cut it a little oversized so it fits tight. It works great. It is amazing the crap that comes out of the can.

I'm using two of those filters but I extended the lines a little bit. I don't see why your idea wouldn't work, as long as the filters aren't mounted sideways or upside down.

I lose about 1 liter of oil every 800 miles. I had an oil analysis done and all is good. Power is good. Everything seems fine. (COBB stage2 with gutted DP) No oil leaks. Really don't know where the oil is going except the PCV system.

Will a catch can like this be beneficial for my daily driver?

Unless I'm mistaken, the valve covers *can* see boost. If you T the valve covers into the crankcase vent line, you're going to be stuffing more foul air into the crankcase instead of sucking out what's already there.

Maybe if you kept the PCV valve attached to both the crank vent and the intake manifold and T'd the valve cover vents in between the PCV and the turbo inlet you'd be ok. Then again, maybe not.
Is this true for all wrx/sti's? Uncle Scotty said that it was only true for the 2.5 engines...

I'm trying to get to the bottom of the mystery as to whether i need one or two cans...

Well, Uncle Scotty knows his stuff.

The above is the conclusion that my research and reasoning led me to. It's entirely possible that I'm mistaken.

Maybe you can get some clarification as to why this would be true for the 2.5's and not the 2.0's?

Wow. These look nice.

Not that I'm going to do it, but if one was ONLY to put a catch can on one of the lines (either crankcase or valve, is that right?) then which would be the prefered one? aka... which one spits more oil?
