ok after searching my problem i relized that the white smoke that is coming from the engine bay is coolant.

what i dont understand is why is mine coming out of the engine and not the exhaust like most of the other people that complained about this problem? ,my radiator was cracked so i just replaced it.

i put in a new one, refilled it until it was full ( i let the car run for like 1 hour @ idle to see if it will overheat again and when the overflow tank filled it was like about 2 inchs about the max line)

was wondering if that will cause my problem? i dont have a vavle gasket leaking but i do think my head gasket it blown because there is oil spills on the lower part of my engine.

Depends on how bad the HG is blown. Usually, water goes into the cylinder and is burned, thus causing white smoke out of the exhaust. Did you notice you have white smoke coming out around the head where the exhaust attaches? If so, you have bad exhaust gaskets as well.

Sounds like you need to replace most seals and the HG.

i just went and checked where the coolant was leaking and from what i can see is its leaking from the pan gasket!! it might just be that it drips from there making it seem that way.
