Just a quicky here, replaced my PCV valve today. I know lots of people have had problems with these. Located on the bottom left side of the oil filler neck when looking straight at it. I found the easiest way to replace it was to 1) Pop off the air filter lid off, and push to the side, 2) pull hose off of PCV valve with a pair of pliers, 3) I used a pair of angled spark plug boot pullers to twist the pcv 180 degrees going counterclockwise, but similar shaped needle nose would work. 4) then just pull straight out...Was very easy, literally took 5 minutes. good luck...
