stx di expansionchamber
 

i hope i am posting in right place; the exhaust expansion chamber froze and burst, i replaced, i may have installed the gaskets upside down.book says fix gasket that the up mark faces upside. did no read that until after job. no water comes out of water overflow. will gasket installed wrong( i have a 50% chance of doing so) prevent water from the water overflow? thanks for any help on the water overflow, larry n
