oil catch can

ok, so im trying to make myself an oil catch can at the moment, because honestly fuck paying $300 for a cusco item, when i can do it for under $30.
anyway, ive been researching, and ive got all i need, hose, clips, suitable aluminium can, bike drink holding thing (to mount) hands etc..
it's just that some setups ive seen utilise a small k&n filter on the top. I'm not sure if this is neccesary, or just for the sake of using it. most aftermarket can's don't feel the need to breathe(that i can see anyway).
so do i need holes in my can to stop it blowing up? I thought that the vapour was being channeled back into teh intake, so this would account for any pressure..
anyway, what i was going to do was, just have a hose from the intake manifold valve, and from the cam cover valve both going into a sealed can, which is filled with steel wool.
Does this sound right?

i don't think catch cans that vent to atmosphere really work that well, i much prefer one as you describe, where the can is really an extended filter and is still affected by engine vacuum. this is more like the proper term "oil / air separator"
filling the can with steel wool would probably just make cleaning it messy. you might find you can just run it without any filter, or use a $1 paper element fuel filter inline with the vacuum source
you may also want to make a little bracket to hold a piece of steel wool or ramflo filter inside the can, at the opening to the vacuum pipe, that way it filters and doesn't look messy

most race cars dont have a filter. just a can with small holes. but if it is a street car i would recomend a filter. it prevents nasty shit ending up in your donk, as it would be driven more regularly than a race car and on all sorts of road surfaces

ok thanks for the help, yeah it seems that the whole steel wool idea would cause more problems than it would solve. It occurs to me that all the little steel fibres would end up being sucked in anyway. so yeah scrap that, i think i'll put a fuel filter inline with the one going to the manifold from the can.
seems to be working fine for now though, i'll see if i can get a pic up for anyone wanting to make one for themselves. looks fairly neat, and ended up costing just over $30.

i'd like to see your work 
if you're a no-metal-skill loser like me, you can also make one out of a washer bottle and mounting bracket, ke30 corollas came with an ideal setup, probably lots of other old toyotas too

I've got steel wool in mine, hasn't caused any problems whatsoever, and helps slow the gases down so that they have a chance to condense... Or something like that.

top fitting is for the K&N filter (or it can be routed back to intake before the turbo).
bottom fitting is for the drain, i just have some pipe and a stopper in it as i can't be stuffed putting it into the sump  .
the two side ones are for each cam cover.

forget the filter! that's like putting a filter on your exhaust pipe, unless you like the looks
or want to keep bugs from crawling in!

Deltathing - Can you post up where you got all your stuff from ?
I've been interested in doing this stuff, but I didn't know where to get the fittings and the can etc ?
Cheers,
James
