Last winter I had a starter failure and so hand cranked antifreeze into my raw water cooled 3gm30. Now it will not turn over, even with a new starter motor. I don't think it cracked from the cold but rather that coolant flowed back, in the absense of exhaust and caused a hydrolock. How do I diagnose and repair this on an engine where I cannot pull an injector. No antifreeze is in the oil sump. And if the block is cracked, how will I know that?
