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!
Don't congratulate me yet.... I still have to get it all back together.

So regarding your sludge comments, I should go ahead and open the filter cap and look in there for a better idea? But wouldn't that still be a high flow area also? As for inspecting valve train, I assume only do this if it is being opened up for some other service, like maybe the vanos deal?
