Re: plugging the pcv valve (streetracinghn)
never heard of doing that.... my PCV valve came loose when i tried to pick my car up the other day and it litterally had less than 1hp to the wheels from 1-3.5k rpm(fullthrottle!)... seriously, i was making a left turn and and it took 10 seconds to get above 3.5k... i guess the motor doesnt use the pcv when you are in boost?
someone correct me if im wrong
sorry i couldt help more

Where is the PCV valve connected to on a Honda? I know that on a DSM, it is connected to the intake tract, so that if it fails it becomes a HUGE boost/vacuum leak.
I certainly wouldn't block it, I would just leave the crankcase side open to atmosphere, and plug the boost side.

PCV valve is on intake manifold near fuel rail, sometimes it's hidden. It's an inline PCV, and there's a little black tube connecting PCV to the mystery black box hidden beneath your manifold.
PCV = Positive Crankcase Ventilation
Purpose= Each compression stroke allows a little bit of fuel past your piston rings into your oil pan. PCV valve releases fuel vapors from your oil into your charcoal canister for later storage. Purge control valve takes those fuel vapors stored in charcoal canister and sends them back into engine to be re-burned later on. Emissions crap

Are you sure about that?
On my car, the PCV goes back to the intake manifold, and dumbs in under vacuum.
The charcoal cannister is something entirely different, it holds onto the vapors from the fuel tank and dumps them into the intake when it decides to save the environment.
They're both for tree-hugging sissies.

Re: plugging the pcv valve (spaceman)
The PVC (positive ventilation crankcase) valve is a much needed device. It is designed to open (spring loaded) once oil vapor pressure is maxxed. The oil vapors are then directed to your intake manifold where they are combusted. You would NEVER want to plug the PCV valve. I recommend replacing the PCV valve yearly. A way to tell if they are fault, shake them. If it does not click, it will not work properly.

The purpose of a breather is to let the vapors breath out of the valve cover. However, the breather also allows air into the engine, which is not a great idea. You won't get proper oil pressure. Plus, the breather will get cloughed quickly, hence oil vapors. I see no problem putting a breather on your intake pipe...

The breather is to allow clean filtered air into the engine when the PCV valve is open.
What are you saying about the oil presure? How is the breather going to get clogged?

My sentiments exactly.
I've run a breater for years, the filter keeps gunk out the motor, and the oil pressure is fine.

Re: plugging the pcv valve (streetracinghn)
Leave the PCV system alone. For those who don't know i will explain what the system is. Basically the pcv system allows fresh air to circulate through out the crankcase and rerouting it through the intake. This then burns any gas blow by and oil gases in the combustion chamber. The main thing it prevents is sluge from forming in the oil pan.
charcol caniser is completly different. The charcol canister is conected to the fuel tank and when you turn off you car the are fuel vapors that would eventually expane the gas tank if it were not vented. Race car vent to the atmosphere but for emission reasons street cars have a charcol canister which collects the vapors and under light load(cruzing) the canaster purges the vapors into the intake.

Wrong, that's just a good unexpected side effect of the system. It's main purpose is an emmision control device. Without it there would be a large amount of hydrocarbons vented directly to the atmosphere.
