Hey guys
For a long time i've been asking myself why is oil catch can good for? Please put down some pros and cons.
What is the advantage over breather filter like this:


Thanks guys for explanation.

It collects crankcase sludge that would otherwise be sucked into your intake. It's also mandatory for track use.

There are no cons

That breather does not provide adequate ventilation.

 

But i still don't see any benefit of it. Having that breather on the valve cover or catch can... I still don't get it. Is it something in catch cans design... Or why should you collect sludge in a can. Of course engine has to breathe, but is the can just to collect sludge, or are there other benefits?

 

So it doesnt pressurize, the breather filter is suppose to go over a can.

Can catches the oil thats blown out a filter doesnt.

 

if you cant understand that a catchcan saves nasty gunk from going into your engine to be burned...
you wont ever get it...

also crankcase vacuum is important
the breather on the valve cover is only HALF the story
there's another line off the block...
the synonymous blackbox...which cools emissions and reroutes them back into the oilpan to save alot of the reburn on hondas/acuras
a good design point by honda...but is the main reason we require more frequent oil changes...
oil from emissions no longer has the lubricating ability...its chemical property has been changed from being superheated....

crankcase vacuum is important...
less pressure in the case makes piston/crank travel easier...
however (cue turbo engines) too much vacuum will start pulling oil off the crank...
i believe the max vaccum you want is about 4-5psi (under atmospheric)
vacuum in the case also helps to seal rings
and naturally aids in the removal of emissions

the catchcan is your winning component to realizing why...
install it and watch it collect all the ****...
also removing your black box and plugging the return line will also keep your oil in better condition for its purpose
highly recommended for catchcan setups

Funny you tell him he wont "ever get it" when you dont even know what the hell you're talking about. Please tell me how turbo engines produce more vacuum than n/a engines. "max vacuum you want is 4-5psi under atmoshpheric" PSI is the total opposite measurement of vacuum, pressure. I'm not going to touch on the rest of your bs.

To the OP, the purpose of a catchcan is to basically catch the oil vapor so that it wont be sucked into the intake charge.

 

Just...wow.

I hope you don't spread mis-information often.

 

really...whats that in front of your compressor...???
i'm guessing it SUCKED your brain out of your head
no a little closer please...i want you to REALLY feel the blood pumping between your ears...
no closer

JUST IN CASE YOU MISSED THE LAST TWO POSTS

 

I think a guy who is ranting about vacuum in psi instead of Hg and talks about a turbo engine's "different vacuum" pulling oil off the crank or whatever needs to check the location of his own brain. You were trying to sound smart in your reply, which could have been short and simple, but ended up with a bunch of crap. GTFO, retard.

I assume he's trying to say the suction created by a compressor is pressure...which it's not. Maybe he'll try to explain further when he gets home from his job at Burger King.

sucking, and pressure, are two complete opposites. I don't know why you haven't grasped this yet.

 

He's trying to say that connecting the black box hose to the pre-turbo intake will create too much vacuum.

However, a slash cut tube in the turbo intake doesn't create too much vacuum - it creates the perfect amount. That's how I have my catch-can setup.

 

digi! what black can should we conect straight to the block, the emission evap can? i got a 97 teg, do i got what ypur talkin about? plz in form

thank you enzospeed...
i wish they could respect the fact that they still have **** to learn even after 5+ years of their holy presence on a car forum

like they think i would post on honda-tech, after being a member since 2002, that a turbo produces more vacuum in the manifold...
uh...yeah...
real cool...
nice way to respect life in the world
clearly their 4000 plus posts since their innauguration onto honda-tech we have experienced such high level of ethusiastic aid in teaching others, learning, and generally helping to spread knowledge...
it is clearly shown in which the way they communicate

i'm not even going to touch on what is actually contained in all 4000+ of those posts
but i can gaurantee this thread as more to come of it

what kind of person would take the time to even be like that
show some respect

well maybe if you studied science in a broader aspect than just your little honder
you would know that on earth...you are surround by 1bar (roughly) of air pressure
why dont you tell me why that isn't rated in inches of mercury...?
and when your car starts pulling vac...in all reality...you are still running at pressure...
zero psi is pretty much unachievable...i dont believe space is even a perfect vacuum...
its pretty close i'm sure

class is in session...if you want to reply to this thread...
you are going to get schooled

or perhaps...
both of us are professional technicians in the real world...
who raise a flag when something wrong/confusing is said....
(and is still never corrected/admitted to)?...

how does a turbo engine pull more vacuum than a naturally aspirated engine?...
measuring vacuum in psi?...
what?...

take a step back and look at your original post, where you ignorantly told the OP that he's not smart enough to get the point if doesn't know it by now...

YOU need to show some respect....

 

Dude, you don't even count the atmospheric pressure of 14.7 psi at sea level.

If this was the case, wouldn't boost/vacuum gauges read 14.7 when your car is off? Am I missing something?

 

you and your little butt buddy need to get each others dicks out each others asses
you want to confront me all hard and **** and now try and hold a conversation
i'll tear your *** apart...bitch

so which do you think it is...vacuum or pressure...?
you dont even know what the expletive you are saying
they are the same thing divided into different human created units to describe the world around us
...the world doesn't change just becuase the needle on your boost gauge crossed a line printed with the number zero on it in your little car in this big *** universe...
vacuum on your little boost gauge is still positve pressure on your skin on earth
its just less than atmospheric
zero psi on your boost gauge is not zero psi in the world
clearly our little alien bitchass visitor isn't from here...probably skinless
just cuz you shut your car off...atmospheric pressure doesn't just dissapear and step2zero

i should have been more descriptive on the catchcan setup
but that doesn't mean its any less valid
using vac pre-compressor to create crankcase vac can reduce crankcase pressure to the point of pulling oil off the crank
a normal pcv valve is actually closed under extreme vacuum
it is limited at both ends of the scale...it prevents reversion
it also prevents 'over-vac'
however it doesn't work as well for a boosted car...
because you still want vacuum in the crankcase at throttle
the vac at this point will be high, pre-compressor
the valve will close and there will be no draw of air



zero psi on your boost gauge = 1bar atmospheric

there's a bigger lesson
respect math...because it respects you first...
in fact it will own you, because it is the essence of respect, even before itself
something america can only hope to achieve
but mathmatics can only narrow in on chaos
to achieve it or overcome it...math must give up its sole purpose : to describe
and take on the act of performing
human creation,intervention,manipulation, WASTE OF TIME

optimal crankcase pressure on turbonated vehicles can be achieved like in the excellent post linked by enzospeed above

you can also put a regulated & filtered line strait to the pre-compressor pipe
like a reverse boost controller...but for your catchcan/crankcase

 

Come on, no need to cry and get all mad.

That big post is nice and all, but when dealing with automotive applications, you don't count the initial 14.7psi of atmospheric pressure. When you start your car and the and you're pulling vacuum, you use Hg, whether or not you want to cite that vacuum is simply a lack of pressure.

 

shutup
