My friend has and oil catch can in his GSR and I've heard that they are good for the car. I really don't know much about them and I was thinking of getting one for my JDM H22a. Do any of you guys have one and if so, how do you like it? Is it worth it? Thanks for any help

The guy is asking for opinions of its use on an NA application, not how to hook one up on a turbo motor.

Yes, they are worth it. A can helps seperate out oil from the crankcase vapors and traps the oil in the can, rather than allowing the oil to pass through the intake manifold and into the cylinders. The oil in the vapor effectively lowers the octane of your fuel, so it's definitely a good thing to have on any car.

 

bump anyone know what a good brand is for one, and where can i get it? thanks

 

Moroso, summitracing.

 

i can get you a cusco one for like $120 plus shipping. brand spankin new

 

and oil catch can is simply used for reducing engine friction in crank casing and the for the pistons. this actually give u more horsepower.also what u can do is get a oil catch can for ur head so there is no friction at all. and if u want for get titium valvues springs and retainers. they do these things for every nasscar and f1 for less problems for the engine. less ristriction give u hp known fact a car that has 300hp really has 350 but friction makes it 300 so u lose 50 hp

ROFL, what the hell are you babbling about??? Your confusing the use of a catchcan with the concept of Positive Crankcase Ventilation.

Stupidest thing I've heard all day. Try redoing the 4th grade one more time.

 

lol holy crap that makes no sence

 

um... as far as i know the catch cans have something to do with oil lol, bump for more info on what they really do... just not from that guy lol

what about the breather that lets oil into the intake? i know you can put a breather filter on it but it looks dumb and it gets full oil every week as my bro found out

 

i see... well then i guess the breather filter does the same thing as a catch can- cleaning/replacing it every week seems kinda like a lot, but i would imagine it's keeping that much oil out of the intake air, so it's keeping the octane up.
so does the catch can have a filter in it or does it just kinda reroute the oil back into the engine elsewhere?
I'm interested now!

 

The can just collects oil from the vapor that passes through it, when it's full you simply dump it.

From everything I have found, the tube actually does not go from the crankcase TO the intake, the concept is that it goes from the intake TO the crankcase when the PCV valve opens up. When the PCV opens up the pull from the intake manifold pulls the crankcase gasses into the manifold, this creates a suction which pulls fresh intake air into the crankcase through this tube. I guess you could kinda think of it as a Negative Crankcase Ventilation maybe?

This is why there is no valve on this line, and why putting a breather on it is a bad idea. Without being connected to the outer side of the throttle body intake charge you run into problems with stale air staying in the crankcase and the backup you see in the filter. Someone posted pics before of a comparison of an aged motor with a small filter's head vs. a normal aged head with similar mileage/driving style. There was noticable build-up ONLY on the corner where the filter was placed, and the normal setup was even.

Basically, it is the lack of a low-pressure flow at the end of the normal tube which the filter lacks which causes a problem with the crankcase gas flow and PCV operation.

I'm sure in some racing applications it may help, but you may want to remember that these are also vehicles which get regular strip-down/rebuilds after races.

Just my info...

 

when i take my filter of my intake to clean it it has some oil on it that has driped down from where the breather hose goes and i wanna stop that as well i thought a catch can could fix that
