The 97 Honda VTec PCV valve should be on the valve cover. The valve is a plug-in type and just pulls free.

there isn't one buddy......
The previous answer is somewhat ambiguous as to whether there is or isn't a PCV valve on a '97 Civic. I have a '97 5-speed Civic LX, and I just had a new PCV valve put in last week. There definitely is a PCV valve, but for this year/model, it is harder to find than on other years, where, apparently it is easily accessible at the top of the engine. Because of the location of the PCV valve in my Civic, I had to pay an extra $35 in labor for them to put it in. If in doubt, read your owner's manual! There is pcv valve on a '97 civic. The dealer schematics will tell you differently, but I've looked where the dealer schematics said it was and it wasn't. Don't waste your time looking for it cause it doesn't have one.
It's located on the back side of the intake manifold. It's screwed into the manifold.
The PCV is located on the driver's side of the engine. It is at the same level as the spark plugs, in the middle of the engine. It is not seated in the oil cover. It is seated in the oil diverter.
go to autozone.com and it will tell you exactly where it is.
Mine is Civic DX 97. Believe it's the same. Get under your car, take off your oil filter, your PCV valve is right above your oild filter. It's recommended to replace it from there. Good luck!
Take a look at the following Flickr photo. This is a '97, but the PCV is located in the same spot on the '98. http://www.flickr.com/photos/roy_vanegas/2921211470/in/set-72157607808188158/
