Heavy leakage on 2009 BMW 535i

[Lestad]

To start this off its best to give alittle back story, this was my mothers and has been sitting for about 5-6 years when i first started my journey as a mechanic at 6-7 years ago my one goal was to get this car back up an running. Soi replaced the spark plugs, valve cover gasket, ignition coils amongst a varation of things. Still never could get it to run. Yesterday i decided to purchase the car and double down on repairing it. Turns out since it was sitting so long the fuel broke down and was preventing it from starting so i pumped all the fuel out put fresh fuel in it and with alittle starter fluid it started. But after revving it to keep it started i got out the car and look down and saw all the oil that was in it immediately pool out onthe floor. I looked underneath and its coming completely above the catayltic convertor i have no idea whats above here since i specialize on N55/B58 motors so if you have any ideas thatd be great,
Thank you.

Well, I'm no mechanic but, if that's engine oil indeed, and if you replaced the valve cover gasket correctly, and if you don't see any leakage from above in the engine compartment (such as from the oil filter housing gasket, perhaps the oil pan gasket is the culprit.
But N55 is not much different if you say you know that well.

Oil plug? That’s a lot of oil. And the pool up front, is that coolant?

Does it leak when it just sits or is it only when running?
