Oil in Coolant

1998 Escort has emulsified oil in the coolant. Anyone know what the likely source is? Oil cooler? Head gasket?
Thanks

I'd first say head gasket....

Yeah.. Sounds like the head gasket blew.

head gasket, but my head was in good shape, just the gasket

happened to my 91 LX last week....

yep, head gasket, I still ain't got all the oil out of my system from the head warping....
