Rear main seal leak.
So I just got finished doing some repairs, and clutch on my mini. When doing the clutch I replaced the rear main seal.
ive only driven it a couple times since the repairs, and I've gotten a 4-5" puddle on the ground after driving. Intially I thought maybe the power steering hoses were leaking. But once I got under there and took a better look didn't seem to be the case.
I replaced the hoses anyway, since they were old and leaking slightly some.
so it looks like it's leaking from the weep hole were the trans and oil pan meet. Even though right at the weep hole doesn't look to oily. Going towards the rear it gets more oily (probably just blowing backwards at speed)
long story short is it most likely the rear main seal?
Got damaged when installing? Don't remember feeling like I damaged it. But it took some work to get it fitted. Just stinks i don't feel like removing it again, since I just had it removed.

Jack it up, clean everything well under there the start it and look for oil dripping. Make sure it’s on solid jack stands and the e brake is holding. If it’s leaking that much from the rear main it shouldn’t take long to see the drip. Run it up to about 2000 rpm to get good oil pressure which will help speed the drip up.

Yeah but how are you going to know where the oil is dripping from if you don’t visualize it? That’s why I said get under it while it’s running. You want to rule out or rule in the rear main. If it’s not dripping from the weep hole, which you said you couldn’t tell previously, then you can start looking somewhere else for the leak.

I did look under when It was running but didn't see anything in that amount of time . Then I thought maybe the angle of the car would prevent it from coming out of the weep hole if it was leaking from there.
plus with everything clean, if there was a clear wet spot on the other side of the oil pan obviously it wouldn't be coming from the rear main seal.
This morning when I checked there wasn't any puddle on the ground but a little wetness around the weep hole were the pan and trans meet.
I'm guessing maybe not as much oil since it wasnt driven and didn't the romping of going through the gears at higher revs.

think it’d be the bottom, back, left side of the motor. Where oil pan meets trans.
see pic attached. Right bottom of the pic you can just get a glimpse of it. Sorry horrible pic
