Help - 200tdi antifreeze in oil sump

I have a problem with my Disco 200tdi. I have lost the cooling fluid. I checked the cylinder head and I changed the head gasket but the leak is still there. I removed the oil sump and on the second main bearing cap I saw a clear antifreeze. I have no idea where the problem is coming from. Does anybody know what is the problem?

cracked block or head

Or oil cooler in the rad fooked .

I doubt its the oil cooler as the oils runs at a higher pressure than the coolant, but it may leak when its cooling down, certainly worth joining the pipes together for a test if nothing else.
