If you could tell me where its located that would also be nice. (Front or back of engine) Please be detailed.
 
The pcv for your civic should be located in the top right or left of the engine above the valve cover towards the firewall. It's rather easy to fix as you would simply lube up the ends of the rubber hoses with grease or WD-40 and then you remove the hoses. PCV is Positive Crankcase Ventilation, so replacing this is essential to let your Crankcase breathe. It's about a 10 minute fix at most and if you need help with the component location you can ask the people at your local Autozone, or try Autozone.com for more details. Good Luck
