They told me the hole is there to vent pressure incase of a over fill or the fluid heats up and boils.. There is another thread( Mine) on G37.com and one guy over their confirmed the hole, As his kit was overfilled from Stillen. But to get to MR.Sqeeze's reply yea from the hood, Either rain or when I washed the car..

I just read the onwers manual from from to back and back to front and did not see anything about I vent hole, or / warning about water or washing the engine bay.. You know like becareful there is hole on the SC and you could contaminat the SC with water if not careful or coverd while washing???

If I have to rebuild it I will go with the impeller, Becasue I will be sending it to 928, Vortech is 3 weeks behind, I will not wait that long when 928 is 5 days.
