I have a snapped bolt holding the oil pump to the timing cover it seems the threads ride up into the pump any suggestions, also there are what looks to be score marks on the block from the chain, are those supposed to be there? and i noticed number 4 on her way down there is tiny spots of coolant in the bore? is it cracked at the water passage if so can it be welded from the inside? any tips?
