Twin turbo operations

[FlightInstChris]

Our flight school just got a twin turbo seminole, and I was
wondering if anybody knew how to do procedures for engine out
operations without destroying the turbo on it. Any info would be helpful.

Most turbochargers use engine lubricating oil supplies to the turbocharger center housing when it is used to cool the unit and lubricate the bearings. Because of the location of the turbocharger unit on some installations. One-way check valves are needed in the oil supply and return lines to prevent engine oil from draining into the turbocharger when the engine is not in use.

I assume this is what you are asking about.
