Sorry to hear of this, but I am afraid you are going to have to "bite the bullet" on this one and replace the head gasket. The symptoms that you describe--the dark stuff in your coolant, white smoke coming out of the tailpipe, overheating at one time all point to a bad head gasket. But open the cap on your oil filler and look for emulsification on the cap. If there is, then coolant is getting into your oil which is bad news. Otherwise, as you explain it, oil is getting into your coolant which also is bad news. But there is a solution--replace the head gasket...the only problem is that it costs money, time and inconvenience. Good luck!
