the only time you will need a catch can is if you remove the vaccuum line(s) going from the oil fill tube to the intake manifold. The line(s) vent crank case pressure (and any oil that overflows due to that pressure) into the intake manifold.
N/A engines have 1 vaccuum line and I believe TII engines have 2.

The correct way to do it if you remove all the emissions & don't feel like routing it back into your inlet duct is using a catchcan and a breather filter, however, some of us cheat and just route it to the charcoal canister.

i was thinking about using the charcol canister as my catch can, but if its gonna allow stuff other than to hit my turbo im gonna think twice about it

bottom line is get a catch can or keep the pcv valve in place. a catch can tends to do the job a little bit better. . . a correctly designed one anyway.
by letting oil get into your intake you allow once useble fuel to get "caught up" in the oil. you no longer can use the oil since its on the walls of the intake.
keep your intake flow area clean. . . youll flow waaaaaaay more.
the charcoal canister isnt the same thing either. its an emissions device that cleans the fuel vapors prior to venting them to the air. . . its also a safety measure. forget about it. . . mines been gone for a long time.
the oil that would go into the charcoal canister would clog it up and would no longer do anything. and you dont really want to risk getting little pieces of charcoal in your intake.
when you put a catch can in place you have three ports. one is an inlet coming from the oil pan. this port needs to have a baffle directly behind it. the baffle catches the oil and keeps it from moving around in the air. without that baffle the can is pointless. the oil will stay in the intake and go right into the turbo. the second is an outlet going to the TID. by making that the cans outlet you are making sure that the can constantly sees vaccum. this means that the oil pan will always be properly ventilated. the third port is a drain. using a screw type drain that you can buy from ace hardware or wherever. this allows you do simply drain the built up oil.

oil gets routed into the intake stock. Have you even seen the inside of an intake? Mine has oil comming from the Purge vavle(when I had it). Perhaps it shouldn't go into the turbo but in the intake it won't hurt anything. If it would my car would have some problem because of it.

fart on a friends head!!!
well, i dont remember a purge valve. . . i have never seen an oiled intake system. clean efficient airflow is the ticket.
yes, i have seen the inside of the intake as well as my engine and various other parts of my fd. having oil in there isnt the best in the world. tell me what this purge valve is.
the only time that oil is injected into the intake on my car is at the rotorhousing. . . and that is 2cycle oil.
to be honest, i really dont remember a purge valve. it was a good thing that you got rid of it. if oil is in your manifold its just gonna cake up and not be a very good flow helper.
i cant believe this is a controversy. oil and intake piping dont match. that much is obvious.

is it supposed to or is it just doing that because it goes bad? i really dont understand why mazda would try to put oil into the intake when they try so hard with a pcv valve to make sure it doesnt. haha.
