i just wanted to see who has a catch can and how you ran it on your h22 since the pcv system on a h series is totally different than a b series. so lets see some pics and explanations of why you hooked it up the way you did. thanks.

 

ill try to get pics tommmorw.
i ran the line from the intake side (b4 the turbo) to the line going into teh valve cover (not the PCV valve the other one).

 

i always wondered, alot of the time you put steel wool in the can, what keeps the fragments from that getting back into your engine is it because it has to route up or something so just gravity or is there some sort of baffle in the catch can

 

The Moroso can has baffles built into it to filter oil out.

 

h23a, same thing though.

 

cool pics. but one thing though. you guys didnt give any explanation on why you hooked them up the way you did or what not. cmon i want details. i understand the pcv on the b series but not really on the h. so someone enlighten me.

 

I don't understand. The PCV system works the same way on the H series as on the B series, it's just located differently on the valve cover; and some of those B series blocks already have a cannister on the back. What is there to tell?

Do you need the details on the actual catchcan with PCV valve and stuff, or just the differences from the B-series, cuz like I said there is none, excpet for placement?

well on the h22 the pcv goes straight into the intake manifold from the valve cover.. it doesnt go back into the block like the b series. just wondering the differences.

 

Ya, there's no cannister on the back of the block of an H series. It just goes directly into the plenum. Otherwise the setup is exactly the same. You want the tubing to be as big and short as possible. Many people do what I did and take out the cruise control. Otherwise finding space is really difficult.

 

The reason i run a catch can is because at high boost, the crankcase ventilation causes a bit of oil to come out through the breather tube of the valve cover.
Basically all VTEC engines all suffer from excessive crankcase pressure at high power and RPM levels. This is caused by extreme piston speed, long camshaft timing events, and a PCV system that is completely inadequate at high throttle angles and low manifold vacuum levels. A lot of the B series engines are based on new blocks where Honda deleted the breathing "can" (on the rear of the block) that you were talking about, causing these engines really suffer from extreme crankcase pressure (frequently high enough to rush past the seals, blowing the spark plug wires off the plugs.) Pressures like these cause oil and other contaminates to severely degrade the quality of the mixture in the cylinders, reducing power and greatly increasing the possibility of detonation.

 

not an h22 but it might be useful

Gude... where did you buy your catch can, and how much was it... do you have any better pics of it?

 

sorry its night time here (i took pic anyway.)

maybe you could give us a better one tomorrow, i can barely make out the GReddy logo, but that's about it

 

yea tommorow damnit air get out of my cooling system..

 

Why don't you just put a breather filter on it then? The only point of running the hose back around to the intake would be emmissions inspection and you're already way past the point of passing anything like that.

For those that want the pretty Greddy can, it's not internally baffled, so if you want it to actually filter out vapours, you'll want to baffle it yourself, like they do in that c-speed article.

 

well heres mine. i decided that since im not worring about emissions that i would just run both lines to the catch can, to take all the fumes out of the intake all together. so who knows. heres a pic.

what kind of can is that?

 

i have better pics of it on my computer at school, remind me to email you some of them. i got mine through options auto salon. http://www.optauto.com

 

Do you guys remove the PVC valve and run the line from the valve cover to the catch can? Open line w/no valve?

I'm planning to install one soon...

Thanks

 

With the Moroso Can you remove the stock PCV valve and run a larger one that fits into the top of the can itself. You can see it in the picture above. If you use another can you'll have to keep the tiny stock PCV valve.

I'm sure it's been posted here a hundred times, but if anyone wants it, I'll take a look for the parts list on the Moroso setup.
