on any Honda I have ever owned it is a little black plastic pipe bent at a 90 degree angle behind the valve cover on the right side with a black rubber tube that goes to the intake manifold

A PCV is always located off the intake manifold its a black rubber hose and these are very inexpensive they are usually between $3-$12 depending on the car, make, model, ect. A easy way to check your PCV valve is to remove it from the rubber hose and shake it, if it makes a noise its fine as its a one way check valve. This is why it has a rubber hose connected to it because that is a vacuum line that comes off the intake manifold. The top of it will usually be made of a black plastic the bottom will be made of metal if its on an older engine which this type will go into the valve cover. If its all black and is bent at a 90 degree angle which they all usually are, it will be inserted into the crankcase of the engine instead of the valve cover. All this valve dose is recycle unburnt gases from the engine back into the intake manifold so that they can be burnt in the cylinders.

They didn't make and Si in 1998. The PCV valve is on 1998 Civic SI's are located on the bottom of the intake manifold. It is acessed from the bottom of the car, you have to remove the oil filter to reach it.

No different dashboards and cluster wiring are involved. Honda also did not make an SI in 1991 and the car model and type is nearly completely different.

Honda Civic Si and Honda Civic Si EP3 the same thing. There are several different year models of of Honda Civic Si's. EP3 is the chassis code for that specific Civic Si 01-05 was the EP3. So the new Civic Si 06 to current two door model is the FG2. By the way the chassis codes are found in the VIN#.
