i have read quit a few threads on this already. But i am pretty sure i have a cracked block. I have replaced the heads and put all new gaskets in the upper end of the motor. and while we had it apart we inspected for any cracks and turned the motor over and could not see any cracks in cylinder walls, valley, or cylinder heads. where else would the block crack from that would be causing this? would it be a crack in the cylinder wall below the lowest point of the piston? or i have heard of freeze plugs breaking, if one of those broke would it be leaking outside the motor? or are there freeze plugs in the motor that you cannot see without for say taking the oil pan off?
going to be pulling the motor unless for some reason we find something really obviouslly that we dont but its not looking good. so any help would be appreciated!
