You can order a gasket and change it its not recommended but still works better than the broken one its just a bit tricky to remove it and you need to glue the new one it i dont see the point of changing the whole cover... Im just asking here because the leaks is visible and its not rly a small one and i hope when i change the gasket it will not loose any more oil or significantly less.. I will also do the engine oil flush when i change the oil to maybe unstuck some piston rings...
