Lately after parking my car I started noticing a little bit of oil under the car where the driveshaft is. I’m pretty sure it’s transmission oil. I saw a hose/line around that area but I don’t know what it’s for. What could be the source of this leak?

Auto or Manual?

Usually, it the transmission tail shaft seal that leaks.

It’s engine oil coming from the valve cover, traced the oil that was on some fuel line and I could see the valve cover leaking. My father recently did the gaskets and I guess they didn’t seal properly.
