Oil Leaks, they suck

[SlickGT1]

Found a few drops on the garage floor about a week ago. Looked like oil. Got under the car, bunch of shit is wet. Did a bit of xoutpost searching, and got a few ideas of where to start looking.

So, I am leaking, looks like at the Vac pump. Half of it is covered in oil. When I say half, picture taking the vac pump and dunking half of it into oil like a you would a doughnut. Had a bunch of grime on it, so I think this issue presented itself much earlier, just not enough oil makes it down to the floor, especially when I am driving it every day. The past month it has been parked 4 out of 7 days a week, so I guess it had time to make it down to the floor.

I plan to order this kit and repair the sucker.
BMW 2004 745i Brake Booster Vacuum Pump Seal Kit 11 66 7 545 384

Notes for self:
-- for the 3x M6x25 torx bolts use 8 torx socket[listed previously] and torque this M6 bolts to 10 NM [from the factory they are torqued to 10.5NM] - Note : dry !
-- in order to turn the engine by hand [manually] by the main engine bolt - use 27mm 3" DEEP 6 point socket or 1-1/16 6pt deep socket - [the 12 points are to lose] .
-- also you will need 1x 20 mm O screw clamp to replace the original one on the hose from the vacuum pump ....

If anyone has a better suggestion, lets hear it. Now, if oil got into the brake vacuum system, what do I do to get it out?

I also pulled out the plug on the oil pressure switch, and it was full of oil. So ordering part number, 12618611273 Seems fairy self explanitary.

Notes for self: Note: [Oil and screw in] 24mm 6 points -- 3" deep socket ---- 20 Nm torque

My other issue, is what seems to be the friggen alternator bracket leak. I am a bit scared about this one. One guy I talked to, said subframe has to come off. A thread I saw on here, said the front diff has to come loose, and spun a bit, while the engine raised a bit. Is there a good how to for our cars about this problem. I was planning on tackling this myself. Thanks.
