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.
