Check all the coolant hoses and pipes, especially where they connect (top and bottom of the radiator, connections to the engine and water pump). If there is no antifreeze in the oil registered on a dipstick, are you sure the antifreeze isn't just trickling down the side of the engine?? If it is doing this it will gather at the seal of the oil pan and travel to the lowest point, where it will then spill over, looking very much like it is leaking from the oil pan when in fact the leak is elsewhere.
It has a failed seal/gasket/freeze plug.
Failed oil to water cooler ( usually antifreeze from the radiator ) Water entering through a seal, Dipstick, axle seal, etc Drove into deep water and it came in through the vent.
Think you may have bad head gasket, seal or cracked head. Water is getting into your engine which usually causes white smoke. Also leaking antifreeze is from these same causes. Hope this helps. Ken
In the dip stick cap.
Failed seal. Replace it.

Overheating can damage any seal.
the seal of Nebraska looks like this
At the end of your dipstick female part (part that stays in engine when you chkng the oil) you have a small rubber seal.
Failed gasket, seal, plug, cracked housing, etc.
Take the dipstick tube with you to the auto parts store, and see if they can match you up with one.
