Oil Seepage?

Tried to search but don't really know what to call this. It's on the bottom of a 2008 E70 with 4.8l and can be seen thru the cut out on the aluminum skid plate just in front of the oil drain plug as seen in this photo. The dampness goes back to just past the next bolt there and doesn't go any further forward than the picture shows.

Most recently I've had the alternator bracket seal replaced and there was oil everywhere. I used about 10 cans of brakleen getting the residual oil cleaned up and there still seems to be some oil finding it's way down this seam here.

I'm hoping I'm just overthinking this and it's just oil that got in the crack and every time it's warmed up a little more comes out??


Not sure if it'll slow up and go away or if theres a reason it's leaking. I wipe it off every evening when the wife gets home and it doesn't seem to be getting worse.

Anyone have any ideas?

That's the front differential. 14mm hex nut to remove and drain. Mine doing the same thing.

My '11 X5d had this issue. The diff had to be replaced under CPO warranty as several seals started to go and the are not replaceable.

Right on, I think I'm going to start looking at a new Yukon. This rig is amazing to drive but a bit too heavy on the maintenance.
