ohhh thats what its called pcv.
When i got the car it was leaking oil from the PCV valve and the pcv valve was barely sitting in there so i sealed it with a gasket so it would stay in there and not leak oil everywhere. But what's causing smoke to come from there and also i took the oil filler cap off to see what the oil looked like with the engine running and it was smoking and spitting oil, things are looking worse and worse everyday D:
i guess i gotta go get the codes read and get a compression test, i have NO idea whats causing this
