The advantage of an oil catch can is to keep oil vapor out of the intake track, where it can gum up the intake.
I cant see the pics on the g35 site but if what its what I think it is (a compressor air line filter) and the whole install cost less than $20 its not going to work very well. Most of those general purpose air filters will not filter oil vapor out. For that you need a coalescing (sp?) filter which cost a good deal more.

Yeah, this catch can set-up may not capture all of the oil vapors. However, it gives a good indication of whether or not a real oil catch can set-up is warranted. I drove a total of 24.1 miles, today. At the end of the day there are a good 2 to 3 drops of oil sitting at the base of the catch bowl. Hmmm . . . I'm wondering how much might accumulate over more miles. This is going to be quite interesting.

Honestly I wouldn't use something like that because it might put pressure on the PCV system. If that filter gets clogged then you will have seals leaking oil. I don't think any catch can has a filter. I remember with the old greddy design, a lot of people including myself would put steel wool but not enough to clog the system. The system needs to be free flow.

I had never intended for this catch bowl set-up to be permanent. I simply wanted to see how much oil, if any, would be trapped in this contraption. Based on what I have seen at the bottom of my particular catch bowl in the last 144 miles, I feel that a real oil catch can set-up is warranted for my car.

We either removed the filter; for myself, I drilled a 1/4" hole at the bottom of the filter..
Yet, I am looking into either adding baffles or steel wool to increase the surface area for condesnation of oil vapour
Advices are welcome !

I bought all the pieces but still haven't put it on the car. The first thing I noticed is that the inlet and the outlet are at the top of the unit right next to each other. Without something to separate them it seems like a lot of the oily vapor goes in and right out.
I've been looking for a fine mesh wire cloth, the material used to make fuel filters, etc. The problem so far is that I can't find anyplace local selling some of it. I may just spring for the Greddy or something similar.
