Blown Head Gasket!!??
 

im not sure if it is or not...there is coolant leaking from the exhaust manifold and it is burning off coolant when its running...and i refill the coolant every so often.

is there white smoke blowing out the exhaust? can you smell the coolant when you turn on the heater or when the car is running? is the car running hot with no power?

Take your oil cap off. If its milky in there then u have teh BHGz. Change your oil and watch it come out, see if its bubbly or milky.

make sure your little hoses at the back of the engine haven't got splits etc in them

have you checked under the car to see if it's leaving puddles?
