Question
Hi, I wanted to know the location of the PVC valve on my 2002 Mercury Sable.  I have been searching for this for 2 years now and have not been able to locate any repair manuels.  Please help.  

Answer
Marc,
  I am a parts expert, not a Tech. I have tried to explain this to All Experts but I keep getting technical questions. I will do my best to answer your question and I hope it helps. I looked in Mitchel on Demand and had a friend look in All Data. The first question that comes up:   Is the engine a 3.0 over head valve or a 3.0 dual over head cam??? This makes a difference. Since this information was not supplied, I quierried about 6 tech and the general concensus is, depending on the engine, it could be in the rear valve cover OR in a hose that runs from the rear valve cover to the intake.  
  ALL suggestions were to look at the engine and find a hose that is about 1/2" outside diameter and is connected to the intake manifold or the base of the throttle body. This would be the manditory source of vacuum for the PCV system. Follow the hose carefully and look for the valve. As stated above, it could be in the hose, not at the end. Just follow it and see what you find. Please let me know what you find. CarPartMan@aol.com. My name is Skip.
  IF you have NO luck, you could always take the car to the dealership and have a Ford Mechanic point out where it is.
