Engine damage 2weeks after private purchase

Hello toammen, bought a Passat Bj98 two weeks ago, ran according to Tacho 113000, bought by private, first hand. Yesterday on the highway with 130kmh the engine burned down.. Engine damage. In the workshop I was told that the car has never seen a real oil change and bized around a round number more. Engine is completely scrapped. Can nothing be done with it. Can I throw something at the seller after a private purchase, legally speaking? in reseller, it has been registered to another person. Search now engine for 1.6 gasoline. Where best? Scrapyards?
