Default How to diagnose an oil leak properly?

Got a 2001 s4 that has sprung a pretty serious oil leak (.7 quart/week) that need attention. I got underneath and cleaned it all off with a couple cans of brake-clean last week. I thought I could get under this week and see where, but the oil is everywhere from the wind/fan. It got really bad after I change the oil a couple weeks ago, understandably. No black/white smoke... so I pray it's a loose fitting or old hose.

I was going to rip off the front end and just look around the turbo area (it's NOT the head gasket), but I was told that I should call up my Mechanic and ask him to put it on the lift, after I brake-clean it again down the street from him--- and maybe it can run on the lift for a bit, and the oil will start seeping out.

Anyone have any suggestions? Thanks & Happy Easter.

Nice, helpful for me as well, though the mechanics told me it was a cam seal, and that makes sence with this article.
