Rick-
I have the same setup using the Campbell-Hausfield filter. I didn't cut the filter or run the lines backwards though.
BTW-you can pick this filter up at Wal-Mart for $11.00 minus the fittings.
After installing it I drove to Portland (300 miles) to have a 15% pulley installed at mini-madness.
We noticed that the OCC had about an ounce of oil in it so I decided I would dump it when I got back home.
So 300 miles later, approx 600 miles round trip, I went to dump the can and it still had the same amount of oil vapors in it (I expected twice as much).
I went to S. Cal for a week following that and drove about 2000 miles at freeway speeds and never dumped the can.
I went to dump it when I returned home and the level was the same as the PDX trip.
I have a feeling the excess is being sucked back up into the outlet tube. I can't believe after 2000 miles it only accumalates the same amount as 300 miles.
What do you think? What's happening to the excess if any?
George at Min-Madness did suggest that the size of the bowl was insufficient and that the occ would fill up pretty quick.

Bart - as noted earlier, I first tried it the way it is marked. It was catching oil and apparently was running it down the tank walls, as the filter in the middle stayed clean.
However, it occurred to me that if the tank filled up to where the level was higher than the bottom of the filter (tube), incoming air would force oil up the tube and out the outflow - not what I had in mind.
If I were doing it again, I'd just drill a 1/8" hole in the bottom of the filter and not cut off 1/4", as I believe that the rough surface texture of the filter tube is quite effective at catching the mist, particularly once it is saturated with oil. I don't see any need for metal wool, as there is no detectable oil going out the outflow tube - it passes the clean q-tip test.

How about this can....
....not $16.00 though. Probably $50.00 or so. All metal with a sight glass
and small. If I do the catch can, this is the way I'll go.

I just added this low cost OCC yesterday. Took advantage of all the prior advice: the intended inlet is actually the outlet, cut off the bottom of the internal filter, and put a piece of a stainless steel scrubbie inside. On OldRick's recommendation, I bought 1/4" ID fuel line, but I don't see how that would ever fit on the PCV or the gray tube, so I went to the usual 3/8". To make it easier to drain, I drilled out the schrader valve at the bottom and added a bushing and a cap. That way I won't be wearing out the plastic threads.
The IC was actually dirtier inside than I expected. There was some black gunk in addition to the oil. I think the oil-coated IC functions as a 2nd stage air filter -- any dirt that gets thru the first air filter is trapped in the IC!

Nice job inimmini..............a simple do-it-yourself mod that is cheap to try. If nothing else.......it gives you an excuss to take the intercooler off and see what's inside.
My catch can is holding up just fine and although I don't get much oil in it, I think that is do to my style of driving. Will see what develops after the 16% pulley install that I am planning on doing.

1/4" fuel line fits fine on both PCV and grey pipe - I had no problem installing it. You just have to warm it up a bit first and spit on the pipes to lubricate, then twist while forcing it on.
(Human spittle is an ideal high-tech lubricant that dries and sets to hold rubber pipe in place.)

where to get this?!?!?1
hi guys im new to this NAM thing but i can't help to help you guys out, ALL these items you guys are running around looking for this in all different places, all you need to do is go to the home depot and go to the tools area and ask for an air compressor filter and there you will find the same filter but in a better color. . .BLACK. it is made by husky, i know i have this mod in my mini and i use to work there, while you're there you might as well pick up the brass fittings in PLUMBING, after that go to the paint dept, and ask for some steel wool, and then you are ready to install this altogether all at the same time, just to let you guys know, thanks.

i did mine and used 1/4 inch fuel line. the car sent up ses and wouldn't run right at all. pulled the line off and it instantly ran better. the vacuum off the grey hose is massive!!!! if i plug it the car will stall. the by-pass is opening fully so there's a nice big loop there; so what's up ? is my throttle closing all the way?shouldn't it be open a bit with a warm engine?

Yes, I went with the 3/8" lines as well, they seem less likely to kink and more likely to flow.
I put this all together yesterday, took about an hour including the shopping and it seems to work well.
Have had some problems with fitment and my Xenons. Attaching point are different than in your original picture cause mine is an 2002.
But, altogether an great idea and an inexpensive mod!
Thanks,
Paul
