      Oil in coolant reservoir

      2011 Aveo LT automatic
      Oil in coolant reservoir
      Just had head tested, resurfaced and gasket replaced
      Transmission fluid level is normal, oil is low.
      Passed coolant pressure test and held 17psi


      Any suggestions before I rip the head off yet again for the 3rd time?

      Did some research and found a video where the oil cooler gaskets failed and mixed fluids. Probably going to look into it.

      A leak down test will tell you if the head gasket has failed or not without having to rip things apart.
