Greetings,
Blanked N1 or N2 or N1 or N2 equal to ZERO, OIL pressure ZERO or close to, OIL quantity equal to ZERO, VIBs, you need a combination of a minimum of two of these to be certain that you have an engine damage, in any case if it happens in real life you will know it for sure.
Engine Failure is strainght froward the engine is windmilling in other words the all parameters are at a very low idle
