Question

well ok it isnt my car, im hoping to buy it. and the guy says that they told him it was a blown head gasket (by the way can anyone tell how much that costs to be replaced) and i just want to make sure thats what it is

Answer 2

first to have a cylinder compression test , then to do

carburetor work or idle control  etc.

Answer 3

white smoke means something is wrong with the top half of the engine black smoke means the bottom half, usually.

Answer 4

You more than likely have a blown head gasket or cracked head. You don't give much information to work with. Did it overheat? White exhaust indicates engine is getting coolant into cylinders.

Answer 5

depending on the type of car- $500 and up to fix the head gasket, more if the heads are warped or cracked. I would not buy that car unless you are only paying a few hundred dollars for it.

Answer 6

guess you overheated it didnt you ran it hot .. blew the motor or the head gaskets

Answer 7

>>  why does white smoke come out of the exhaust?

Ouch!!  That is a strong sign that your head gasket is blown (or even worse your heads are cracked.

$$$ to fix.

Good Luck...

Answer 8

White smoke is normally a sign that water is leaking into the cylinders, possible head gasket failure or crack in engine block.
