However, it's generally located on or near the valve cover, often towards the back of the engine. It's a small, usually black, plastic or metal valve with a hose connected to it. Look for a hose running from the valve cover to the intake manifold; the PCV valve will be somewhere along that line.
To find it accurately:
1. Consult your owner's manual: This is the best source for the exact location for your specific vehicle.
2. Use a repair manual: A Haynes or Chilton repair manual for your specific year and model will have diagrams showing the PCV valve location.
3. Use online resources: Search for "2005 Chrysler Town & Country [your engine size] PCV valve location" on YouTube or a car repair forum. There are often videos and photos showing the location.
Important Note: Working on your vehicle can be dangerous. If you're not comfortable performing this task yourself, take your van to a qualified mechanic.
