I checked the service manual for my Civic and found that there was a simple procedure for inspecting the PCV valve. I thought I'd check it out since the car burns a little oil and that's one possibility.
The instructions said to pinch the PCV hose with the engine idling and listen for a click. I couldn't hear any clicks, even with my stethoscope, but I'm not sure whether that's because the valve is malfunctioning or because .. it's kind of hard to hear a small click over the engine noise.
What were they getting at with this test procedure? Why would the engine have to be idling for it to click? Should I have to pinch the hose totally closed? I'd rather not remove the valve to check it because it's kind of hard to get at.
