How to test PCV valve
Pinch the hose while the engine's running, you should hear it clicking.
I always thought that was kinda ghetto. If you wanna take the PCV valve out, you should hear it rattle when you shake it. There's a little ball on a spring inside the valve.
Clean it if it's full of oil. Blow through it very gently, it should flow pretty easy. Blow through it harder (from the engine towards the manifold) and it should close up so only a little air flows. It shouldn't close completely. Blow the other direction (towards the engine) and it should close completely.
Then after you've done all that, ask yourself if it's worth $8 to just get a new one anyway.
ps...
I just noticed you're from Moscow - welcome. Maybe those parts are harder to find over there... So maybe it's worth it to clean & re-use it.

LOL - I'm probably being too mean. But finding parts over there is probably harder than we think.

seriously it took you 45 mins to change the pcv??????? wow that is an eternity.......how long does it take to change the oil in your car????

Shake the PCV valve. If you hear tapping then it is good.
If you hear nothing, then soak the PCV in some gas or other cleaner to dissolve the oil in it.
You are supposed to replace it often, but simply keeping it clean is fine.

is it the black valve thingy that sits on top of the throttle body?</TD></TR></TABLE>
No. It looks like a little plastic elbow-shaped hose nipple. Accords have them right on the valve cover, with a hose to the intake manifold. Integras have them buried underneath the intake manifold, on top of the breather box which is attached to the back of the block.

Thanks! In fact it takes a lot of time to order this valve. So i should visit a dealer, pay him about $50 and after that a have to wait for a week o two. :-(

15 minutes, with around 5 to get it jacked up and on stands.

$50 or less for both part and installation. It's down pretty far to easily do it yourself, even w/ very long nose pliers. I'm sure there's a trick to it.
You probably should've bought a Euro made car for the sake of parts availability.

I've replaced about a hundred of these things at my old job and a few on my teg. A set of 90 degree (angled) needlenose plyers is all you need. It sits on top of the intake manifold underneath the fuel rail. Takes 5 min.

non vtec ie ls has the pvc valve on the valve cover. the vtec engines have it on a box under the manifold.

50 for part only.
PCV is the same for European and Japan market cars. There are no GSR in Europe. Onle TypeR and it is very hard to find it in good condition.

PCV Valve:
Positive Crankcase Ventilation Valve.
I forgot the exact use of the part, but I think it protects your engine from vacuum leak. I don't remember from Auto. Don't trust me.

No, I was saying that if Japanese cars are hard to get parts for there, a BMW, Mercedes, Audi, etc. would be a better choice. I didn't realize GSR/SIR/VTI wasn't available there.
I guess you have to spend $50. A catch can may be a good idea, as it'll keep alot of the oil vapors out that gum up the valve.

In the 'old days' there was a crankcase vent. Just a tube or something so the crankcase didn't get pressurized. Often it was an oil filler cap that had a vent.
But the EPA didn't like the crankcase vapors just going out into the air, so they changed the rules. Now all cars have some kind of PCV system. It takes crankcase vapors & sucks them into the intake manifold so they get burned up in the engine.

I heard some buy with a supra talking about how he took off his pcv valve removed the little ball that is inside, then put it back on. He was saying something about how this will help when he goes into boost. I have no idea.... anyone know if this helps?

Besides, if it's not a factory turbo, then anything goes.
Saab turbos have a check valve, so when you're in boost the crankcase doesn't get pressurized. In boost, any blowby flows thru the breather into the air inlet (upstream of the compressor).
Honda PCV valves act like a check valve, too, they close under boost. Without a factory turbo, I don't know why Honda designed them that way.
Without knowing the rest of the plumbing for the Supra, I'd guess he should NOT have taken the ball out. Seems backwards, because you don't want to pressurize your crankcase. Crankshaft seals probably aren't made for much pressure. But even if it didn't do any damage, I don't understand how it would help performance.
