Engine damage Saab 9-5

Hello, just break my head in case of engine damage to a Saab 9-5. Looks like overheating by oil almonds. Does anyone have experience with the engine type? Saab is unfortunately not very helpful, and engine builders have too little experience with the type. Is a 2.3L 169KW year 2000. About helpful and constructive help I would be really grateful.
