Okay yesterday after work, i came home cuz my car was overheating, well turns out the heater hose was having a leak.. so i waiting till it cooled off and i pulled off the hose.. well POOF coolant shot everywhere and so it drained all the coolant from the block, i stuck the hose back on, waited a min to fire it up, it fired up good, drove it around.

as soon as i got out of my street it started to overheat again. so i got it home... my coolant was still at FULL in my resevoir. i started it again, white smoke was coming out, so i waited for it to cool down and as i was taking off the radiator cap it went SSSSSSSSSSSSHHHHHHHHHH... then i turned it some more and poof more coolant shot out, i turned it shut right then. for about 1 hour i was scared to open it, but then i finally did cuz i was sick of it, well for 3-4 seconds when i turned it and slowly took it off, all i hear is SSSSSSSSSSHHHHHHHHHHHHHH. then it stops. i turn the car on, fill the car up with water untill it overflows and i was done.

well today, (next morning) i started it up and it had a rough idle for about 2 seconds, and i'm STILL blowing out white smoke. but i drove it around, it doesn't overheat it feels fine.

no oil in the coolant either... oil looks fine also. what could this be? HELP!
