PCV Valve

I want to know where is located PCV valve on E15(S) engine. From the valve cover , left side, it goes one hose to the air filter, the other one (right side) to a piece of metal, and continues with other hose under carburettor. Is this piece of metal the PCV.
In air filter where the hose come from the valve cover there is a place like it should contain something but actually there is nothing. Should be something there like a small filter?

The car is SUNNY(SENTRA) model 1986

I'm Not totaly sure on the e15 - but on the e16 the pcv is at the base of the TB (carb) follow the hose and you should see it screwed into the manifold.

yeah, follow the hose on the right hand side ( around the transmission ) of the valve cover to the bottom of the throttle body.. I found the easiest way to get it out was to loosen the clamp on the valve, loosen the closest one to it ( so you can take the whole hose out ) and try to take the hose off.. with mine i had to use a screwdriver to get the hose off because it was stuck on. Used a spark plug socket with an extension to get at the valve.. was pretty easy I thought.

In my car between the manifold and the cover valve there are 2 hoses, and between them a piece of metal. I suspect this piece of metal, is the PCV, because at the manifold, there is nothing that seems to unscrew it.
I clean this pieces and seems, but when I put it back again, in the filter are a lot of vapors that are goes to the filter, and when I accelerate the this vapors increase. I wonder why these vapors does not go on the oposite side, because it seems to be clear. Maybe because I don't have the litle filter located in the air filter next to the place where the hose from the valve cover enter?

PCV valve is at the center of the intake at the back. there is a weird rubber hose that slips over it once you get that off you need like a 17 or 19 mm deep wall socket and perhaps a bit or torque, since they are rarely changed... Should only take a couple of minutes to change. you might want to spray some penetrating oil on it the night before...

What is the best way to get at this? Today I was going to change mine and could not for the life of me figure out how the heck to get it out of there?

In manifold I have only a little pipe that seems to be soldered, no place to put a wrench on it. There it starts a hose, and continue to a piece of metal. How is this PCV like? Maybe is this piece of metal.

You may have a home fix hose - because the hose changes diameter from the valve cover to the PCV valve some people (me included ) have had to put an adapter in the middle of the hose to increase its diameter.
