I was thinking of adding an oil catch can to my car.

I understand this is added to turbo'd cars, was wondering if anyone has any insight in adding them on daily driver-naturally aspirated cars.

After adding my CAI I personally don't like the idea of having engine gas/gunk (blowby) recirculated back into my throttle body. I do understand this is setup by factory and is most likely for fuel economy and emissions.

Pretty much I have two questions:
-Will I hurt my car in any way if I add an oil catch can to my car (aside from wasting my money) will it decrease fuel economy, fail emissions? make my run rich/lean?

-Anyone with experience running an oil catch can on a NA DD car? Any problems or issues? Better cleaner intake and throttle body?

Thanks.

Thanks for the input. Im pretty set on getting one now, cant seem to find any good ones used in my area. Just dont wana mess up the install on one of these things.

So install would be something like:

Engine crankcase <hose> oil catch can inlet <house> air intake nipple (and thus back into my throttle body)

Is that the install process.

Ebay kits seem like they'll get the job done, except they dont come with instructions

Ebay Kit:
MITSUBISHI HYUNDAI IMPREZA 750ml JDM OIL CATCH TANK CAN on eBay.ca (item 320640241305 end time 09-Mar-11 11:45:46 EST)




3 questions.
1. which nipple is in/out (on the can) does it matter?
2. based on picture do you know if all cans come with a filter median or is it just condensation (i read that some ppl use lawn mower filter to help promote the gunk build up as rapid air flow may just negate the concept of the oil can)
3. in the picture what is that double sided nipple connector used for?

call me an idiot, but how would the inline filter work?

I would assume it would be installed after the can (so between can and air intake) and it would somehow block the engine gunk, and it would somehow fall backwards - back into the canister? - does this mean i should install the filter really close to the exit nipple? wouldnt this clogg the whole line (well wouldn't there be a chance it would clog the whole line)

maybe im just crazy but I would assume the filter element would be located inside of the canister (and yes I know i could fill the whole thing with lawnmower filter) but then whats the nipple for?


Thanks.



EDIT:
maybe the nipple is like a back flow trap? - liquid can only go one way?

Okay so I would install the filter (the double nipple thing in the picture) after my canister (on the exit side) and it would block all gunk, and somehow 'push' it back into the canister?

like the gasses would passby and the blowby would get trapped at the filter and automatically fall back downward into the canister?
