A full engine tear down is needed.

If the IMS bearing failed (or some other catastrophic failure), there are metal particles (of various sizes) everywhere in the engine. Turning over the engine, even by hand for a compression test, will grind all of those metal bits into the metal components in the engine.

To consider flushing the engine and replacing the IMS bearing without a full tear down is a fool's errand as there is already likely damage to many engine surfaces that needs to inspected and repaired.
