I can think of a few things off the top of my head. The first would be a bad head gasket. Since your engine overheated it's possible the head was warped which is preventing the gasket from sealing properly. There could be a crack in the head between the water and oil passages and also there could be a problem with the oil cooler.

  • @Moab Could you explain a little more? I'm still somewhat of a novice and don't understand your comment. – Robert S. Barnes Aug 27 '16 at 20:23
