leaking coolant out my header

well this kinda funny guys well here my battery died at the house warming up my nitrous bottle...came back to car notice battery was dead so i pushed it down one my hills at my hosue got it started notice i need gas so i went to gas station...knowing not to turn car off cause battery still needs charging so i leave it on to pump gas and i walked away for one sec and cam back noice it smoked everyone out the gas station trying to pin point the problem and i saw i was literally leaking water into the header....guys think this might be a cracked waterjet?...dont matter about this motor i guess time to drop in the zc b ut i just wanna learn what might have happen to this block or head

anything that could have leaked coolant into the cylinder. run a compression test.

If its leaking coolant right into your header, you either have a cracked head, real bad headgasket (or put one on wrong), or have you had a port and polish done? sometimes if they go too big, theyll grind a tiny little hole right into your waterjacket. do a leakdown test or compression. and pressurize the cooling syst. with a gauge and watch if it drops.

no port and polish but ya...thinking mite be the headgasket......would the bnlock leak oil if i didnt deck the block when i had it apart...thats the only thing i didnt have done cause it looked fine to me
