2003 Taurus SES 3.0 L "U" code engine - it's located on the valve cover farthest away from you as you are standing at the front of the car, left side. Follow the Upper Intake toward the passenger side and look for 1/2 inch to 3/4 inch black tube about 3 1/2 inches long. It should be connected to the end of the upper intake and leads down to the PCV. Disconnect the really small vacuum line going to the fuel pressure regulator and then pull up on this black tube...the PCV should come out with it.
If i know what you are asking, look at where you put your oil in. on the valve cover to the top right should be a plug with a tubeing runs to your air clear tube where the air mass sensor and carb is located. i think that is what you are looking for.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The PCV valve is located under the intake manifold on the non-hybrid 2.5L engine. The intake manifold MUST be removed in order to service the PCV valve.
The PCV valve sits in the crankcase vent oil separator.
On 3.5L engines, the PCV Valve is located on the rear valve cover (see pictures bellow). Please note: the PCV valve must be replaced if it's removed. Access to the valve is easier if you remove the upper intake manifold. However, this is not absolutely necessary and if you are already a little mechanically inclined you can do it the way you would replaced any other PCV valve.
-A 19mm open wrench will make your life a lot easier if the PCV valve is a bit tight. It is in an awkward spot to apply pressure.
-Disconnect the electrical connector from the valve. There is a small pin or locking device on the wire that you will have to slightly depress for the connector to release.
-Disconnect the hose from the valve and turn the hose clockwise so that you have a bit of room to work with.
-Turn the PCV valve counterclockwise and remove from the valve cover. Pay close attention to the position of the valve at the point when it is to be removed. The new PCV valve will go in at that same position. Why is this important? It is possible to install the PCV valve facing in the opposite direction. Once the PCV valve in and locked it in place, it damages the locking mechanism. Therefore, if you remove it you will have to throw it away and purchase a new one.
-You just saved $130 - $150 to have the PCV replaced at the dealership...
The blowby vapors that end up in an engine's crankcase contain moisture as well as combustion byproducts and unburned fuel vapors. The crankcase is sealed to prevent the escape of these gases into the atmosphere, but the vapors must be removed to prevent oil contamination that leads to sludge formation. The positive crankcase ventilation (PCV) system siphons these vapors from the crankcase and routes them into the intake manifold so they can be reburned in the engine.
The main component in the PCV system is the PCV valve, which is usually located in the valve cover. A hose connects the PCV valve to the intake manifold. A second hose between the air cleaner and crankcase or other valve cover (V6 or V8 applications) provides fresh air to help flush the vapors out of the crankcase. Some engines have a separate air filter for the PCV breather hose located inside the air cleaner.
Probably not read above for details.
The PCV is below the EGR (exhaust gas recirculation valve) valve close to the intake manifold below the intake air sensor, there is a tube running to it from the engine to recirculate exhaust air with fresh air, there is a clamp holding it to the air intake that you need pliers to remove, then you need to turn counter-clockwise 90 degrees to remove, do the reverse to install. to make it easier to access remove the upper intake. The PCV valve is not visible, however, you can identify it by the 3" inch long rubber hose that connects to the steel line running into the bottom of the intake. I have the part and am going to replace it soon, although Ford really makes it difficult to remove it - PCV valve is located just under the throttle body. remove air cleaner assembly from throttle body and you will see a u shaped hose running horizontally.
The PCV valve is located on top of the valve cover, on the front of the engine. There will be a rubber hose connected to it about as big around as your thumb. It is really easy to change, just pull the old one straight up and it will come out. Just remove the rubber hose, attach the hose to your new PCV valve, and push it back into the hole. Hope this helps!
