I disconnected the PCV Valve tube from the PCV Valve and cannot detect
any air flow so I think the tube may be blocked. Does this sound
reasonable?

I want to clean the tube by removing it and knocking any debris out of
it but I can't unfasten the tube from the crankcase. By sliding my
hand under the (I don't know what they're called but the silver
branches coming from the fuel injector to the crankcase) I can just
barely touch the fastener with a finger after I remove some other
tube/wire mounts. The fastener looks like a band of steal 3/8ths wide
and I can feel two prongs(one thin and one wide) on the underside of
the fastener about 1/4 inch apart.

Can someone please tell me how to access and remove this item?

thanks a lot
Eric
