After taking approximately 3 hour delay to replace the right engine start valve; we departed. Upon reaching FL320 I noticed the right engine oil quantity was zero. The First Officer and I initially thought it was a false reading with other engine parameters normal. We noticed the right oil pressure slowly going down. It became very apparent the right engine was losing oil pressure and it was just a matter of time until we lost it all. I asked First Officer to declare Mayday-Right Engine Failure with ATC and to coordinate a landing back at the departure airport. First Officer initiated the Engine Failure QRH checklist while I made the turn back. First Officer mentioned to me we still had oil pressure and we should wait to pull the fuel control cutoff switch until the oil pressure hits the amber band which I agreed. Upon oil pressure reaching amber band in the descent; we both agreed it was time to move the fuel control cutoff switch and finish our checklists. We landed without incident and parked at a hard stand.
After taking a three hour delay for a start valve replacement on the right engine; a B767-300 Captain notes the right engine oil quantity is zero upon leveling at FL320. Oil pressure begins to fluctuate and the crew declares an emergency and returns to the departure airport. The engine is shut down during descent.
