PCV valve check ; Can it be done this
way as described at this site ? Car in picture is Chevy Nova ( Corolla ) . http://www.ehow.com/how_6821472_tell...alve-bad_.html . Is so , can you leave the hole open where the PCV valve is removed from to the valve cover while the car is running . Hopefully not much oil would come out it . I know you can shake it to listen for the ball inside move ( rattle ) .

Ours in screwed into the valve cover and can be a bear to break loose. And, oil will sputter out if you run the engine with it out. Just pull the hose on the intake manifold and apply suction to it instead (with the engine off). It basically acts as a check valve, so you should be able to apply suction, but it will block if you blow into the hose.

Thanks CT . I have removed it before to check it and it seemed fine. Looks like I will have to give it the shake test again. Yes it can be difficult to remove. Probably best to do this when the engine is cold. Can you put duck tape over the hole while the engine is running to keep oil from coming out to give it the suction test?

If you start the engine when you are doing it, it will be like smoking a hookah.
