Well I did a search and nothing came up and I have looked at the cusco one but it is not in english. SO what does a catch can do and does it effect emissions? In other words will it pass the CA visual.

thanks for any help

CHRIS

 

It won't pass the visual. Where's BSQ when you need him?

 

{EDIT}

Read BSQ's links and ask him, He'll prove to be most helpful with this topic.

what do you mean you wont "pass with it."????

Every one of those threads is someone asking the same questions and being told to do a search. No real info on any of those threads.

 

What makes you say it's "not good for your car?" A sealed catch can with operate in the samme manner as the stock pcv system, except that all the oily sludge won't be dumped into the intake manifold. This sludge causes carbon deposits and invited detonation.

 

Here are 3 threads which should actually help you out: https://honda-tech.com/zerothread?id=113778 https://honda-tech.com/zerothread?id=105992 https://honda-tech.com/zerothread?id=89849

If you still have questions, let me know and I will be glad to answer them for you.

 

Well I understand what it does now but does it make the car polute more or not pass emissions. I live in SHI@Y CA where you have to pass visual and sniffer If it will pass the sniffer I can hide it some way for the visual. Ok so if it pass's what is the best it sounds like the moroso is the best any others that are as good or better?

 

many people think a catch can should be attached to the breather location on the valve cover. IMO it does not go there. Attach the catch can between the stock breather tank and the intake manifold while still using a pcv valve and vacuum from the manifold source. This will remove the majority of liquid oil from the crankcase vapours while still keeping the engine smog legal. I have no idea how strict visual inspections are in your area, but It should pass a visual if mounted correctly and you are able to explain the setup to anyone that cares. As you are not changing the flow of crankcase vapours, only removing oil from them before they are re-introduced into the combustion chamber. Now if you go messing with the breather conneciton off the valve cover it would most likely attract unwanted attention. You are also messing with the direction of air flow established by Honda , which is designed to introduce air at the valve cover down into the crankcase to replace the air being drawn out from the crankcase. As much as some people dislike Larry Widmer he does have some good pics and drawings of a good catch can system at http://www.theoldone.com/sc/type-r/b18c5-prototype.html ,check out the link to the hand drawn picture on that page for a good overview of the system and a schematic.

 

I have to apologize here,

I am the one who is incorrect. I know, I know, I know.

I was actually thinking of the great debate some time ago about the filter attached to the valve cover at the vaccuum line, which I remember being a No-No. I do also remember Tuan being strongly against this little mod but, since I can't clearly remember why I should have just kept my mouth shut, sorry if I didn't help at all.

Ahh live and learn...

And I have to also apologize about the links I posted, they were not at all helpful and just listed alot of other questions.

See what happens when you're in a rush to go Dyno?

Sorry guys, and Thanks BSQ, I also knew you could shed some more light on this subject.
