I have had a number of problems with runaway diesels or run-on dielsels (after fuel was cut off) and all where caused by oil seal failure in the turbo or intercooler . If a fine mist of engine oil is blown into the intake then the engine will run on regardless of the settings of the fuel pump or injectors . Blocking of the air intake or overloading the engine(top gear, jake brake full on and brakes on emergency!) is the only way of stopping them. Would have thought it unlikely to happen with bad rings but I guess its possible. There are a number of diesel gen sets running biogas for electricy production which run down to 5% diesel for the expected power output and I would assume these use the same principle. They use a common gas manifold for the gas supply and the diesel injection only to provide reliable ignition as methane will not reliably compression ignite, the examples of these I have seen (diagramatically) use an air throttle on the intake for engine speed control and the fuel rack is used to cut the diesel flow back to optimum after the engine has been started on straight diesel.
