I recently put a motor in my parts car, so it would become a runner. I hooked up all the radiator hoses and when i put water in the radiator i noticed a small lead that appeared to be coming from between the head and the block. This occured when the car was still sitting and not running.. Does this mean that my head would be cracked and i need to put on another, or is there something else that i am not thinking off. the leak occurs on the sraight underneath the distributer between the block and the head. Any suggestions are welcome. thanks, brad
