Where did you buy urs? I found a site that sold them but i CAN'T find it and im getting pissed off!

 

= bad for your motor

 

just go to any aftermarket parts shop. they should have them for like 15 dollars. Its not good for your engine though.

 

Really? How is it bad? (im not arguing, just curious)...I was under the impression it was better since it doesnt cycle oil thru ur intake and clog ur t/b...

 

Yea, I wanna know too, why is it bad?

Oil does not get into your intake with the hose. If it is, you are doing something wrong. The flow goes IN not OUT, NO oil should come out of that hose or oil breather.
The only thing possibly different with the oil breather is PERHAPS there isn`t such a strong flow of air.

 

Wrong, check your shop manual, the airflow diagram FROM HONDA shows positive flow from the intake into the crankcase, not from the crankcase to the intake. By installing the breather you are doing nothing but interrupting this flow, only necessary if you have a pressurized intake system, i.e. a turbocharger.
A good question is, if someone is going to run N2O, should they install a breather to prevent nitrous from entering the crankcase through that hose?

 

Just run a ctach can.

 

There's no way anything other than boost is going to overcome the flow of air
coming out of my valve cover. As a matter of fact, my crankcase pressure is so
high i'm probably going to have to install vents. Then maybe something might
be able to push its way into the valve cover.

Even so, the stock tube going into the intake hose isnt shaped in a way that
promotes any sort of flow TOWARD the valve cover. I know on older hondas
they were, but all the newer ones I have seen are not.

 

by using a breather is it bad for your car?

 

That`s what I`m saying.
BUT, why does installing the breather interrupt this flow? AND, why do some say the breather is bad for the engine?
If the crankcase needs O2 then it takes O2, whether it is from the hose connected to the intake or through the little breather.
I "installed" an oil breather when I put on my AEM and if this is bad then I want to know so I can take it off.

 

Yeah, i installed my intake and I saw another R with the little breather and that's why I was asking...

 

I never had a problem, here's a pic.

was talking to a guy from BENIN this weekend..he had some crazy insight on the pcv system for hondas..ill keep you posted..if what he said works, alot of us auto-xers and road racers are gonna be real happy

 

There is another hose coming out of the crankcase (not valve cover) that goes to a black box (filter/oil catch can?) and then to the intake manifold. I think that is the crankcase ventilation (pcv). The hose from the intake to the valve cover is for letting air in the engine.

 

Thanks EPG, always nice to be aware of the little tech tip and tricks.

 

This is true. Here is a diagram from T.O.O ( http://www.theoldone.com ) which shows how a oil catch can should be installed on a Honda/Acura.

 

So, this is not the hose that is connected to the valve cover and intake hose. But why do some people connect the hose at the valve cover to an oil catch can? And if the the valve cover hose is sucking air why bother putting a small breather filter on it instead of leaving it stock?

 

Correct. Probably because they are misinformed.


Exactly.

 

This is a picture from http://www.theoldone.com to confirm this.

 

I been using a little breather filter for a while. Maybe a year. I never had a probelm, but if it is bad, I will use a tube and connect it back to the intake. never knew it was bad. Maybe I will get a catch can.

there was one time, when oil was coming out of the breather filter.....that was my only problem. It happened after an oil change. So maybe the oil did go down yet.

Is it bad to not use the metal pcv valve for the intake hose and coolant? I rerouted my coolant to just a tube. bad?

 

Yes, this is the same setup I have on my car. You can go to my website at http://www.geocities.com/bretq/DIY_O...tructions.html for further information and instructions on how to make this oil catch can.

Here is a picture of my oil catch can:

 

Double 06 - what kind is that..that looks cool.

 

jaz catch can

 

Where can you get them?? Thanks

 

If anyone is still confused on who is right... go grab a new PCV and try sucking/blowing on the end where your hose would be clamped on and see which way air flows.
