Anyone know the part number on these? I am referring to the little one way valves in various vacuum lines on the engine. I am chasing a high idle BLM problem and I am likely going to replace these as cheap insurance. I'd take the stock AC Delco PCV valve part number too if anyone has it. Thanks in advance. Can you test these just by blowing and/or sucking through them??
 
pcv is #25095468 which is a delco cv893c...check valves can be either #14047619 or #25523494 this one is gray and black and more heavy duty I was told, either will work.Cheapest place is GMPartsDirect,local dealer still not to high though.
 
Almost forgot,you told me the other day where in SC you are from,I was seeing a girl from Graniteville and also have family in Edgefield and N. Augusta.Beautiful part of the state.Take care.
