02 540ItA - common oil leaks?
Developed an oil leak. Leaving a drop of oil when parked. Checked valve covers, they look "sweaty" but not wet or drippy (yet). I see residue down in front of the engine, but not sure where it might actually leaking from.
What is most common area to look first and what should I expense/labor expected for the common leaks? Will be putting up and pulling lower covers next week, but just wanted some direction in what to check first.
