-What are these anomalies?
A couple that I can think of from the Dash 8.
Oil pressure between 45 - 55 PSI is not enough to run the engine at flight poiwer settings but is ok if the engine is feathered and it can then run hydraulics. However, it is still an engine that's not developing any power (i.e, an engine failure), so you'd be heading off for a landing at the nearest suitable airfield.
Or a prop oversepeed where the prop could not be feathered, you leave the engine running at idle and land ASAP.
In neither of these examples do you "continue the flight" in any way other than finding somewhere good to land.
