anyone made one if these before? got any pics? want to make one for my hatch for fun and giggles.

 

Look in the FI forum FAQ. Lots of catch can stuff in there.

You forgot a picture of Nipples!

 

i was kinda hoping someone would post up one of the famous red bull catch cans lol thats what i wanna use. googled it but no pics came up

 

i used a Air tools filter run a vac line off the PCV and the VC to the one side of the filter, run the other line of the filter to a pre-turbo vac port, very easy and only cost about $20-$25 for everything, I'd post pics but my photobucket account is retarded

 

seen those before. might do that but i liked the redbull ones... cant seem to find a pic of one tho.

wtf is with the steel wool!

why do you want steel bits going back into the combustion chamber

whoever first suggested using steel wool is a friggin idiot.


the proper way to do it in my opinion is plug up the intake nipples and direct both the valve cover breather and crankcase breather (bypass the pcv valve, or just gut it) to the catch can and vent to air.

 

i dont know who 1st suggested it but the guy that taught me how to build motors told me about that.so i use it

 

So long as the catch can does not have a drain going into the block, it's fine.

 

if there is no return to the engine. then why even have any steel wool...

Bringing this back to clear things up

Your statement is true when you have a closed breathing system, but you put in steel wool when you have an open breather system.

The open breather system works like this https://honda-tech.com/zerothread?id=1199935

The new hoses from the back of the block only breath out, so when you lead them to the catch can the gases go into the catch can and then the steel wool catches the oil from the gases while the rest of the air breaths out the filter on top.

 

lol dasher.

that guy needed me to convince him an open breather set up was the way to go.

here's his first attempt at a write up. check page 2 when i begin to chime in...

heres a pic of the parts used with the air tool filter.

 

Bump

Ok, I have a question. I have my car boosted and now I'm getting a lot of blow-by. I put a small breather on top of the valve cover to vent to the air. Well I've been having oil squirt out of the hole. Now I know the other port on my valve cover has a check valve in it. Or at least I think that is what I should call it. It closes under boost. Now, am I having the oil squirt out because the little breather is getting condensation built up causing the pressure to build? I have an H23 and I've never seen a PCV like in those threads listed. There are no ports on the back of the block that run to anything. I'm planning to run a catch can but I'm sure I need more ports then the 2 on the valve cover. I'm just confused.

Edit: the "check valve" is the PCV correct? At least that is what I am getting from this thread. So I am thinking I need to buy some of those fittings that go to the back of the block and run a setup like the link above? Also just noticed this was in the CRX section.

lol. i was wondering why you posted this once i read you were talkng about your prelude.

yeah, the PCV valve is more or less a check valve, but 2 ways. its made to close the combustion chamber to the intake when the car is off tho. and prevent any detonation going to the manifold at sudden pressure increases.

the oil that is dripping from your small filter on the valvecover is exactly why you need a "catch" can, to catch those oil droppings. just put a hose to a can of your choice. you can put the filter on that can if you want. it doesnt matter really.

 

Yea, I searched before and found a lot of threads that just confused me but I searched again just under the Prelude section. Now I actually understand how it works and what I need to do. This site helped me out with the diagrams. I guess just ignore my post.... but thanks for helping me.

 

well, just to confuse you a bit more, i disagree with that method and reasoning for a catch can. (nevermind the stupid idea of putting steel wool in the track to the engine)

to me, its pointless to even think about "cleaning" the oily vapor to put it back in the intake. its only "less oily", its still oily air youre sending back into the intake, the whole point is to ELIMINATE oil from entering back into the intake and recombust.

and especially since you have a turbo setup, thats all IRRELEVANT to you. that diagram shows a NA setup, with the valve cover breather tube still going to the stock intake tube. you shouldnt even have that in your setup. you dont want boost going into the valve cover. the intake should be closed and not connected to the valvecover.

like i said above, i think you should just put a hose leading to a catch can where you currently have that filter and call it a day. its as simple as that.

complications never helped anyone

 

I wasn't planning on running it back to the IM because my car is boosted and that wouldn't work. I made a crappy can and it didn't work. There are no baffles though.

Crappy paint pic to explain how I made it. What happened is it shot oil everywhere again. It did catch quite a bit of oil though.



Here is how I had it at first and what happened.

oh yeah, thats fine. exactly how i recommend. took me a second to figure out what your orthogonal view was in the corner, but i understand now. i thought the lines coming form "breather" were hoses, but theyre just arrows pointing to the breather end.

i see what you mean that the crankcase itself isnt being vented in the case of the H23 motor. my F20C s2000 engine is like that as well.

looking at your original setup, its no wonder why oil was spurting out the filter. boost was creeping through the PCV valve and still pressurizing the head. do it like you showed and that will eliminate that.

 

I made a crappy can like that and still had oil shoot out of the breather. I'm wondering if the condensation from the gases is causing the breather to clog up creating pressure. Do you think it would do that?

 

there was NO connection from the intake to the valvecover then?

i gotta be honest. im not a FI guru at all. so im just as good of a guess as anyone.

do you know if in normal operation the valvecover is pressurized? could the pressure leak through the valve seals?
