Is there a problem with my Series 60 engine?

Why is the series 60 Detroit Diesel engine still running?
In a bid to save fuel, the engineers at Detroit designed the 60 to idle at very low speed. However, it took Detroit about 10 years to realize that the engine’s idle speed was not fast enough to operate the oil pump. As such, many older (pre-1997) engines have had lower engine bearings replaced more than once due to oil starvation.
What kind of fuel economy does Series 60 have?
When it comes to power, the Series 60 tends to favor the higher end of the RPM band. While this works well on paper, the 60’s high RPM horsepower and low RPM fuel economy tuning have given some lead-footed drivers the impression that these engines get bad fuel economy.
What causes a Detroit Diesel Series 60 bearing to seize?
Bearing problems, particularly spun bearings, are typically caused on older Series 60 by low oil pressure at idle. A spun bearing occurs when there is a lack of lubrication causing overheating. The bearing can eventually seize, creating even more problems.
