For those interested or considering installing an oil catch can . . . Here is a very simple and inexpensive method of doing so.

Nice. Thanks.

 

thnaks for the link been meaning to install one

 

what's the advantage?

 

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.

 

Damn, that sounds like a lot for just a 24 mile drive. It's no wonder that the bottom of the plenum has a puddle of oil in the pics from the G35driver thread.

 

Has anybody with a "real" oil catch can ever opened one up to see what's inside? I would assume just some simple baffles to increase the chance of the oil particles condensing out.

 

I have an ARC catch can and it has a sight gauge.. It's on for about 1500 miles and no oil can be seen yet but the hose that is hooked up to it from the PCV is a clear hose and yes you can see oil vapors on the inside of it..

 

Does it just have a drain on the bottom or it is something you can open up to see what's on the inside?

 

It has a drain valve at the bottom...

 

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.

 

Good catch cans are baffled inside.

 

Actually, you don't use the filter that comes with the part. It would clog quickly and nothing would pass through.

 

I kinda' figured that.

 

I love ARC!

 

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.

 

can you use the wire mesh filter discs they sell for oil filters...btw mine is catching less oil after about 1500 miles with it on my car...at first it was grabbing half a vile in 500 miles
