My wife's 2002 Taurus (Duratec) is having some issues that I believe I've traced back to the PCV valve/elbow/hose. One (or more) of those things needs to be replaced. I'm tempted to replace it all just to be safe, but I'm having a difficult time figuring out exactly what the parts are that I would need. I can find the valve itself, and I can find what's listed as the "elbow", but I'm not sure about the rest (if there are additional parts). In regards to the elbow, I see that AutoZone lists a few different elbows as well as an "elbow kit" that includes tubes and connectors. Thanks in advance to anyone who can assist me in this area.
