    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.


    Here is the hole just encase you would like to see. Thanks for any help!

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