I'v read this thread twice...and it doesnt explain what to do about the hose?
on a non vtec motor the line goes from the intake mani. to the valve cover...
anv on a vtec motor it goes from the intake mani to the block...what do you guys do for a lsv or a b20v to replace that.?

not sure what line you are talking about? if you are talking about the breather hose that goes from the valve cover to the intake manifold its the same on all motors. it recirculates back through the intake manifold.

you might be thinking of coolant lines from the intake mani to the block...


take some pics so we can exactly what you are talking about.

run a catchcan setup

bambam

What you are referring to is called the Positive Crankcase Ventilation system. It consists of a one way check valve known as the PCV valve, an oil catch system, and some rubber tubing.
During the normal process of combustion, it is normal for some of those combusted gases to get past the piston rings and into the crankcase.
In all 90-93 B18a and Bseries dohc vtec motors, crankcase gases (blow by) are routed up through the factory breather box on the back of the block (basically an oil catch can), then through some rubber tubing, to a PCV valve, then through some more rubber tubing back to the intake manifold where it will be consumed again by the motor during the combustion process. The PCV is a one way check valve that opens under vacuum (incoming intake air). That little pipe in the passenger rear corner of every honda motor...that's where some clean incoming air is routed to the head and down into the crankcase to help evacuate those blowby gases. This incoming fresh air is important to help ventilate the crankcase.
94+ LS and B20 motors do not have this box. The PCV system is routed directly through the center of the valve cover and into the intake manifold from there - there's no breather box.
So, when using a 94+ LS or B20 block, you must install an aftermarket breather system to evacuate the crankcase from those dangerous fumes and pressures.

If you notice on lsvtec/b20vtec setups that don't have either a factory or aftermarket PCV and breather system, they will "blow" air out of the corner of the valve cover instead of draw air in, which it is intended for. This is because that is the only place for crankcase gases to escape. Bad ju-ju.

^^^oh so you mean just ignore it?
and them what happens to the nipple on the intake mani?

just do it the right way get a catch can setup and help out your rings

No. I didn't say that. Can you get away without it? Yes, but the life of your rings will be reduced, not to mention, you will have to change your oil more often because you will get more build up, sludge, and harmful deposits than a motor that has a PCV system.
Get an aftermarket oil catch can system.

this will govern the decision i make of abortinng the whoe b20v idea...is the aftermarket catch can expensive and are those things plug and play?

bambam

They go for about 50-100 on ebay depending on what brand you want (OBX, Greddy, etc.). Endyn also sells a complete kit for 190 shipped.

Will it run? Yes. Is it smart? No. Why don't you go and search exactly what the PCV system does. Then you'll understand why it's important. If you don't run one, you will accumulate unburnt hydrocarbons, water deposits and every other by-product of combustion into your oil pan, where they would normally collect in the oil catch can/breather box. This will seriously lower the quality of your oil and oil change intervals will have to be increased. There's a reason every modern car has one.

It's even more important in boosted engines, where the manifold pressure is too high to allow the PCV to open. I would never run a boosted setup without an aftermarket oil catch setup due to the fact that the OEM PCV system will never operate correctly under boost.

i know that the b20 and the newer LS blocks and also H22 doesn't have the box... so why do you need to install one if Honda didnt supply one with the motor in the first place??

so the life of all of the factory crv's are shortened because they don't have the box? and the integras with no box are going to be getting new rings every 2 months because honda didn't know what they were doing?? come on... thats just ridiculous..

this is a stock B20 vtec... i'm sure it will be fine..

if it was boosted or a high compression motor then yes i would suggest a catch can setup...

but thats the same for any motor, regardless of the fact of if its a B20 or Ls block, or lsvtec or H22, or Gsr or type r. or anything else....

to say that the life is shortened by not having the box is incorrect.... it doesnt have one from the factory... if its a stock B20 Ls-vtec then you don't have to add it.. and nothing will happen.

again if its high boost, or high compression then i'd suggest a catch can setup.. but thats the same for any motor not just the b20 or newer Ls..

there is no need to waste 200+ dollars to put a catch can setup on a stock b20 vtec...

You're an idiot. I said he needs a PCV system. ALL engines have a PCV system. on 96+ LS motors and CRV motors, the PCV valve is integrated into the valve cover. Where as on the 90-95 LS blocks and vtec motors, it is integrated into the back of the block an through the intake manifold.
If you use a 96+ LS or CRV block that had the PCV system in the head, and you remove the head and put on a vtec head that came from a motor that had the PCV system in the block, now you don't have a PCV system.

Also, don't put words in my mouth. Next time, use the quote button....because I never said you'd be replacing the rings every two months. Those aren't my words. I said it would work. But, it would be BENEFICIAL to have a Positive Crankcase Ventilation system installed and working properly. This can be proven by having your oil tested at 3k for contaminant levels when using and when not using a PCV system. I will bet money the oil without a working PCV system will contain much more contaminants than the oil tested that utilized a PCV system. You want dirty oil circulating in your motor? That's your choice. I sure as hell know I don't. I like to take care of my motor and I hope the original poster of this thread does too.

Again, I didn't say they all have a catch can. And honda did know what the heck they were doing because they DID put a PCV system on all of their motors jackass. You think they just randomly baffled the valve covers on 96+ LS and B20 motors? Know that's for a reason. I'm not using opinion here like you guys are, just simply stating facts from reliable sources. I never said it wouldn't run, or wouldn't run right...just that it is beneficial to have one. I'm not discrediting the fact that you've taken apart motors and have personally seen P2V contact...but that can be attributed to numerous factors. 100% stock B20vtec's with the cams properly degreed in will not have contact.
