Oil in Coolant

Hi all,

I have chocolate milk in the coolant overflow tank, but no sign of coolant in the oil. I have changed the head gasket, radiator, all hoses, and water pump gasket. I have also drained and refilled the coolant many times since completing the job, but am still seeing oil in the coolant. Is there anything else I should try or should I just assume the block is cracked?

Thanks for your help.
