content: Absolutely.  If you lose a turbocharger seal, the truck will begin directly injecting engine oil (which is used to lube/cool the turbo) into the cylinders.  Turning the key off does nothing.  Diesels don't care what goes down their gullet as long as it ignites when compressed.  The only way to save your engine is to throw a rag into the turbo like the guy in your video did. This one is my favorite.  Make sure you watch the ending.
