Well, all I can say about older technology and 13,000 flying hours is that I only experienced four emergency engine shut-downs. Two (singular) on a C-130K, one on a B747-100 and one on a B747-300. The B747-200 was extremely reliable; as was the TriStar -200 and -500. The two engine shutdowns on the C-130K were both due to a hydraulic pump break-up. As for the engine failures on the B747 - one was loss of oil and the other was a turbine failure.
