yea im going to do something.and the kicker is that i had the block hot tanked for the build so in the morning im going to pick up another gasket for the housing i broke it. then flush it the best i can.. ohh my coolant is green not nasty looking at all so maybe it was just some random ass piece of rust the size of my finger nail on my pinky finger that slipped in while it was closed and made it not open all the way
