Good Job ElwoodBlues. Some comments.

1. D/C battery ground or red: in this case it does not matter that much because you are remote from the battery.
In contrast, the long-standing recommendation of D/C ground cable (you are correct) applies for battery that is located in the engine compartment: to prevent arcing.

2. My PS Pump is the earlier model PN 32 41 1 094 098, IIRC there are 3 bolts holding it.
But anyway, your idea of supporting the PS Pump is excellent: a small bucket or a whole bunch of bricks or whatever underneath the PS Pump should be fine.

3. And you are partially correct re sludge.
The Oil Housing is such a high flow area: gallons of oil flow through there per minute.
So when the engine is shut off, oil collects in the:
- Oil Sump
- Engine Valve Train area
- Oil Filter area.

So if you want to look for sludge, look in those areas.
But you brought up some excellent points.

Congrats on a job well-done! You just spent $5 (oil housing gasket) and save $200 of labor charge!
