The sump is connected to the engine with a sump gasket. It's visible when you look underneath your car. If you don't see any cracks or leaks, there's a good chance the sump gasket is leaking.
You can replace a damaged sump yourself. This can be done with or without a jack, although it's easier with one. Keep in mind that this is a messy job. So be prepared with an oil drain pan, the correct tools, and all the necessary parts such as the drain plug and sealing ring.

Oil vapours and combustion gases form in the sump. These are harmful if they are released into the air without complete combustion. That is why it is important to also have a properly functioning crankcase ventilation system.
