headgasket is blown

 

and this is for sure right /?? is it hard to change this ?? if it is whats the going rate to fix it???

 

yah, the headgasket is most likely blown...DO NOT DRIVE THE CAR anymore...fix it...it is not that hard, but i have no clue what your mechnics skill level is. basically, you have to disconnect the wiring harness, disconnect exhaust manifold...take out cams, under the cams there are 8 or 10 headbolts (i can't remember) take those off from outside in (meaning take off the outside bolts in a cross pattern and take off the middle bolts last) and pull off the head to get to the headgasket. i could do it in like an hour, so its really not too hard...might wanna get a helms manual to give you a more detailed description...
