if you look exactly down where the civic's oil filter is...it is directly on top of it!!
theres only two cable that you will see directly aligned with the oil filter...the PCV if im correct is the secondone looking down from the hood...if i remember correctly!
***The PCV valve is located on top of the engine in the intake manifold below the fuel rail...to be more specific!!

Mine was a real pain to get at and when I replaced it, the one that was in there crumbled and I had to remove it bit by bit with a needle nose pliers.
Luckily no bits fell into the crankcase
I'm not sure if it was the cold weather (below 30) that caused it or just crap plastic + old age.
After it first crumbled I warmed the engine to make what was left come out easier, should have done that to begin with

what kind of bad idle are you talking about??? Too low rpm or too high?? because the civic should idle at about 675rpm!

but talking about low idles!! I know that if you have a leak in the vacuum hoses it can cause the car to idle lower than usual...but i dont know if that is the only thing that can cause it!
