    Hello im not sure what this is but i don't like how its open and water can get into it. I was told its the SAS system that sucks air from the transmission cover and blows it into the exhaust system but i'm unsure.

    Does anyone know if i can cover the hole or something so nothing gets in it? Or what it actually is as i'm still not sure.

    Just put a bolt in it if it's bugging you. There is a one way valve that the hose is attached to
