Did you make a homemade catch can or did you buy a commercial unit? I ask because I'm considering making one myself and I'm open for design ideas. I've seen several that use an air compressor filter but them seem pretty small and would need to be serviced (emptied) often.
I am going to make one home made. There is a guy down the street from my uncle who works with aluminum.
I saw one from ARC for an EVO, had two lines for hoses and then a third line on the back. Instead of putting a return line, I plan to put a breather filter from K&N or other company on the third line on back (oil stays in the can, fumes go out just like the Golf of my cousin). I probably have to open up the guts of the PCV filter as it normally requrires the vacuum of the engine to open and close.
Of course, I will have to drain this thing out every so often.
