Quote from ATSB "During the cruise the crew observed a gradual decrease in the oil quantity for the number 4 engine. As a precaution the engine was reduced to idle for the remainder of the flight.
A subsequent engineering inspection found that the fitting of the external HP/IP oil line had less than the required torque. The investigation is continuing."
Who's to blame this time?
Let's blame Little Al J. for outsourcing the manufacture of these aircraft and engines...
