my 92 geo storm has had a slow coolant leak for awhile, while i had it fired up today i notice a considerable amount of water comming out the exhaust, i would rev it up and it would spatter all over the driveway, there is also a lite appearance of white smoke. the oil is not cloudy/gray like water it leaking in there. could i have small head gasket or head leakand its not getting in the block? please help i dont need my 32+ mpg vehicle blowing up. thanks, chris
