Really hard to tell anything with that recording but hissing sound could be an exhaust leak in combination with a blocked cat or a vacuum leak, maybe even at the pan gasket since the crankcase is under vacuum and looks like you some oil leaks. Maybe try tracing sound with a piece of rubber hose held to your ear.
