just had my 425 rebuilt with a 30 bore comp. cam, the guy who did the rebuild said that he had problems with the pulley thats located next to the water pump, he said that the water pump was leaking, so he replaced it, got the car home and i noticed that water pump had cracked right next to that pulley, it not leaking water, its just a little ring of cast iron between the pulley and water pump. Can anyone tell me what can cause this to keep happening?
