Impossible to tell the difference between a cracked block, cracked cylinder head or a bad head gasket without disassembly and inspection. Coolant will NOT always show up in the oil when a head gasket leaks. It depends on exactly where the gasket is blown and how large the hole is as to where the coolant or combustion gasses go..
