Have you tried dye yet. Perhaps clean it up and then add the dye start checking with the black light. A friend of mine tracked down a small leak that I had using this. I remember it didn't take much dye at all and this stuff really glows.

I like the GoPro idea because it gives an excuse to buy another camera.
The power steering pump is also a good idea.
The last accessories belt got shredded into little pieces and some of them stuck under all the pulleys. It is possible that some of those seals (front main seal, PS pump seals) got ripped.

Was the belt wrapped tightly around the pulley shafts next to the seals? Did you have to pull pieces of the belt out from the edge of the seal? Did you remove all the pieces of the belt that failed?
Seems reasonable to me that such a situation can cause a damaged seal to leak under high rpm's.

This is a known problem caused by a shredded serpentine belt. Sorry you didn't mention it sooner. One result (seems you got lucky here) is to force pieces of the belt past the main seal into the oil pan. Result is to clog the oil pickup and destroy the engine.

OK, at least I know what the problems are. The front seal is leaking. And the steering pump is also doing its part. The pump is $1400 ...
I did pick out all the bits and pieces of the old belts. But, no telling what is hiding behind those pulleys.

Make sure your mechanic drops the pan and cleans everything out when he does the main seal job, including any crap that might be in the oil pickup.
Good luck.

I have a serious oil leak over the front of the engine on a 2008 535i turbo engine. I have changed
1. Oil filter housing to block gasket
2. Oil filter housing to radiator lines gasket
3. Looked at o ring for the oil lines to the radiator and they are not leaking at the engine or at the radiator.
What can it be?
