SOURCE: PCV valve for 2004 Hona CRV
PCV Valve Operation:
A vacuum-controlled metering device that regulates the flow of crankcase fumes in the positive crankcase ventilation system by allowing more flow at high speed than at low speed, and acts as a system shutoff in case of engine backfire to prevent an explosion in the crankcase.
Depending on your engine size, the PCV is a different style and slightly different location.
Usually they are mounted in a hole on your valve cover.... connected by a vacuum tube.
Some are mounted with threads into the engine block (usually by the oil filter)
On the '04 Crv - it is nearly inaccessible behind the AC compressor and beneath what looks like an old vacuum advance. Most PCV valves today do not need to be replaced, unless there is actual valve failure, which I have not seen happen. I would not be concerned about replacing it.
Thanks for using FixYa - a FixYa rating is appreciated!!

You have to remove the "ignition cover", ie. the plastic cover that says 3.0L, you will see a hose coming from the passenger front corner of the intake manifold, that is one of the two PCV hoses, the other one is on the rear driver corner of the intake manifold.
Follow the first hose downwards and you will find the PCV valve just below some other tubings, it sits fore/aft, i.e. lengthwise to the car. I hope this helps good luck

Under hood, center, upper engine area, top of engine, MOUNTED IN THE VALVE COVER (probably has a rubber hose connected to it, coming from a place further back toward the firewall) It usually is removed by simply pressuring it upward out of the rubber gromet that it resides in.
Hope this lets you find it.
