motor was not running good so took in to shop & they told me its getting water in #1 cylinder.they said i have crack in block.when i went to pickup asked if it could be anything else.they said it could be head gasket,or some kind of other seal.now they are going to pull head gasket & check.so what else could it be or do they not know what they are doing.also what is the block made out of?if it is a cracked block is there any way to fix it?
