Yeah it's a GM tamper resistant pcv valve. It's got a little braket thats attached to the valve cover that keeps it in place. You can see it clearly, but can't pull it out with out taking the little bracket off. It is my mothers car. She took it to a quick change place that over filled. It suck up oil. It is soaked. Does anyone know how to get that bracket off. It looks like you have too take the valve cover off and unbolt it from the inside. Someone has to know. If not will it hurt the pvc valve by getting filled with oil?
