However, to be absolutely certain, you should:
* Consult your owner's manual: This is the best source for the exact location on your specific vehicle.
* Check a repair manual: A Haynes or Chilton manual for your year and model will have diagrams showing the PCV valve's location.
* Look online: Search for "1999 Dodge Ram V8 PCV valve location" along with your engine size (5.2L or 5.9L) for images and forum discussions.
The PCV valve is a small, usually plastic, valve with a hose connected to it. It's fairly easy to spot once you know what to look for.
