The leaking oil seal at the rear end of the crankshaft will get worse. Oil is leaking out of it. Oil lubricates your engine. When all the oil runs out, the engine parts will rub together and your engine will stop working. Once the seal starts to go, it will quickly get worse. Your engine will start losing oil faster. Please do not be blocking the road when your engine freezes up.

Of course it costs a lot less to get the oil seal replaced than to replace an entire engine. I did it myself years ago. (At the time I was out of work, had very little money, but a whole lot of time.) It is easy to do but a whole lot of stuff must be removed before you can get to it. That is what takes the time. I recommend taking it to a mechanic who does that work every day. He can do in an hour what took me 2 days.

NO. You either have a rear main oil seal leaking or the back of the intake leaking oil and even could be a valve cover gasket leaking. But I would say the rear main is leaking and when the engine is running the flywheel slings oil onto the starter.
