oil in coolant

[stang3O2]

I noticed the coolant overflow tank had oil in it after driving today. There was no signs of coolant on the dipstick or oil cap. Does that mean bad headgasket? It is a 2000 ranger xlt 3.0 140kmiles
thanks

could be a cracked head too.. Our '92 was getting oil in the coolant quite a while (50k miles or so)..


I had the heads pressure tested and found 6 cracks in the head, including one on the hump near the end.
