I'm curious too cause mine needs to be replaced cause my check engine light is on and giving the PCV valve code as well as a "very small emissions leak" code. If I had to guess, it's under the breather that connects to the throttle body. If nobody answers by the end of this weekend I'll have one cause I plan to take care of mine ASAP so I can get my vehicle to pass inspection. Matt

The PCV valve on a Dodge Ram 1500 5.7 is located in the air filter hose that goes from the air filter to the motor. On any vehicle, the PCV valve can be located by starting at the air filter and going to the end of the connecting hose at the motor.
