water bypass problem, need help

[dbmx66]

well i fixed the problem, i sharpened a skinny piece of metal into a really small knife kinda thing, poked through the gasket, started cutting aound the hole, about 3/4 the way around i stopped, bent the piece up with needle noses, held the piece tight with the pliers and finished cutting it out, it worked well. im gonna take a small flexible tube the i can fit down the hole and vacuum it out, there isnt coolant in yet so i doubt if there were little pieces that fell off, that they didnt good far. i think im fine.
