Does anyone know much vacuum (if any) the PCV valve should be drawing at idle. I'm talking about at the end that sticks into the valve cover. I'm thinking it should be either zero or close to it, right?

Yeah you shouldn't see any vac on it - it's needing vac to do it's job though. Be sure it's floating freely, you can clean them up with carb cleaner sometimes if you think it's hung up.

A shot of carb cleaner took care of the problem. Thanks.
