I've had my Weapon R catch can for about 8 months and whenever I drain it (every oil change) nothing comes out. I mean even the drain plug is bone dry. Nada. Both lines have taken on a rich brown color (they were clear). Just wondering if anyone else with a cc doesn't "catch" anything. It's installed correctly BTW

 

I have a DIY one and I've had it one for about 5 or 6 months now and it has very little to no residue. The lines that I used aren't clear, but I'm assuming that it's just oil residue in your lines.

 

Congrats! your engine is still in good health.

 

What side is it mounted on? Breather or PCV side ?

 

this should be a good thing lol...but yes, what side is it on?

 

2 months running and still no oil in catch can.

I guess it means the motor is breathing well.

i had oil in mine. i empty it 2 times already. car runs great tho. hum. now you are making me wonder. i only emptyed it like 1 time every 2 or 3 mounths. it was maby and inch high. i have a greddy cc

 

i had the WR catch can in my 03 8 for about a year and never a drop came out.the lines were discolored like stated above but i guess i was breathing well also

 

coloured lines indicates "stuff" coming out. the reason you are not catching nothing because there is no "condensing media" in your catch can. The "stuff" aka oil vapors go in one tube and comes out the other.

on my catch can(jam packed with SS turning), the tubing leading to the catch can is dark, but the tubing after the cc is clear.

Search for SaiKou Kun, he has posted a lot regarding this.
