Surely there isn't THAT much gas mixing with oil? I had 2 on my SRT-4 (talk about blow by) for over 16,000 miles with no issues, other than having to empty it (PCV side) every week and a half or so........Campbell Hausfeild FTW.
Anyone put an oil catch can on?

yes it does . that is when the PCV valve is open and drawing oil vapors directly into your manifold...idle. there should be very little blow by on hard acceleration. the PCV should be fully closed at that time. if your PCV valv sucks you will get blow by. that is when you see the oil in the CAI and intecooler. mine gets a very lite mist in the CAI but it has never made it through the turbo. my IC is always clean. many cars have the smoke at idle with and without exhaust mods. more often than not a catch can fixes it. look on the subaru forums. TONS of those guys have stopped smoke with a can.

The feedback seemed good on that product so I bought it..I hope its not a pos but if it is it only cost me $27.Im guessing if it dont have any leaks it should be just fine.I do wonder what it looks like on the inside.Im hoping that the inlet and outlet lines are not right next to each other on the inside so it dont just suck some of the oil back into the vac. line.

I bought a generic catch can from ebay before and it didn't work. Previously, I had bought an HKS catch can that did work!!!
I had both cans installed on my previous car along with inline filters and the HKS filter was clean while the generic ebay can was oily and dirty; it was worthless.

Im not sure but if the HKS was clean and the generic one was dirty woundnt that mean that the generic one was working since it had stuff in it?

No, I had installed an inline filter on the outlet of each can...the outlet of the generic can was always oily and dirty as if it wasn't catching anything. While the HKS one, the filter was clean...the can was catching and filtering.

Oh,Ok..I was just going to ask if I should stick a inline filter after the can to catch vapor but I guess I should.Ive read that maybe sticking steal wool in the can helps,Im not sure it thats true.If I have to I can just add a cheap filter after the can and change it a few times a year since it will only cost $2 or so.

Damn, I never thought about that!!! Adding some kind of filter material in the can (the one that didn't work) like steel wool...
Anyone interested in or confused by blow-by, breather systems, catch cans, etc should read this article! It also explains the difference between the crankcase-to-intake manifold (aka plenum) breather and the cam cover-to-intake (aka CAI) breather. I found it very informative and cleared up lots of confusion.

I highly recommend slogging thru it, it's actually pretty well written and concise. I'm currently on pg 12 and have already learned a lot

I'll be looking at it on my next oil change... I have a spare HKS can laying around...I'll write one up if nobody does one before my next oil change...
