Hi tink. First question - did you retorque the head bolts after installing it new? Most manufacturers recommend retorquing the head bolts after a short interval of a few hundred miles. It gives the gasket time to bed in from going through heat cycles. And they nearly always leak coolant if the procedure hasn't been followed. I'd try retorquing it as you got nothing to lose + it hasn't leaked into the combustion chambers...yet.
