Hy guys I was browsing in Autobarn today and saw these little fellas.
They are called air breathers, and they are smaller versions of a pod filter. The filter size is slightly bigger than a 50 cent coin.
Anyone knows whut are they ancd care to explain their function?
Thanks!
I dunno aye....
BTW guys here's a pic

OH
put them on the top ofyour catch can/oil breather or if you are japanese, you would call it a surge tank, but not in Australia
Is it? Any good?
Any pics showing their application?
hang on, skyline's and silvias always have them, so look for under bonnet shots... we have a catch can on the race car, so I will look in our archives
one of these

Whoa...okay....okay since I am curious, and a ill knowledged guy, what does an oil catch tank do?
well, it separates air from oil... catches excess... its a safty thing...
DAVE, i know you are here.... answer....
Well, these breathers..besides teh oil catch tank...no other applications?
oh, I' sure they prolly do other things
riceboys prolly hang them from their rear vision mirrors instead of air fresheners
oh! now i get it!!
hee hee....
Becaus i see one fitted somewhere along some pipings as well. Not too sure whut piping are those though.
U can stick them directly onto any crank case. Its just a breather for the PCV system. If u get a heep of blow-by, then u use a catch can to help separete the air from oil. otherwise u can just attach one of those guys to ur crank case and let it vent to the atmosphere. Note: if u do get blowby with the breather, expect some oil in ur engine bay.
:thumbsup:
what he said exactly. altho venting causes a DEFECT
Hmm..does that mean that it removes excess pressure in your engine oil? I cant imagien engine oil spewing out to your engien bay though
the PCV (positive crankcase ventilation) system is built into all cars. From factory it is ducted straight into ur intake manifold. U can mod it with a 'cool' breather if u wish..
Yes air does come spewing out, ive got a good video of a turbo b16 with HUGE blowby. This usually indicated advanced o-ring wear though.
IS that the little pipe that goes to the air filter? Something like a fat straw
yer from ur valve cover to ur airfilter or throttle body.
Yeah. That is the one
Its attached at the end of the crankcase breather hose. This hose usually feeds back into the intake manifold and as a result reduces the combusting efficiency slightly. Hence people use such a breather to keep the oil vapour out of the chamber.
Note though, that it is defect worthy as it vents to the atmosphere.
Oooh! Okay! Competely understood now. Thanks guys!!
What you need is one of these:

You can either connect it to the valve cover or inbetween the PCV valve and intake manifold.
Okay...another question guys
An oil catch tank. Their applications are most suited for a Turbo car right? Either that or a larger capacity N/A car.
So my puny Civic does not need it?
so guys, any good?
Ive got one on the teg the way I figure it is if their is any blowby (unlikely in NA motor) but incase I dont want it going into throttle.
