I thought I had it pinned down to above the oil cooler lines because that's typically where I see the drop. What confused me is I see a small amount on what I think are transmission cooler lines going up the other side of the bell housing. I guess I could take an inspection camera and put in down the back toward the oil pressure sensor I just didn't know if it was typical to see a leak from there. The leak looks like it starts fairly high up.

Hey all, just picked up a 2011 Yukon XL Denali with 130k+ on it. There's been a little back and forth with the dealership I bought it from because I noticed a bolt backing out on the driver side motor mount they replaced. I also noticed an oil leak and had it back up there twice. The shop they brought it to two said it was the cooler lines but I noticed if I crank it cold and let it idle there will be a small drop in the driveway 10 minutes later. It looks like its coming from up top but the valve covers look fine. The oil pressure seems ok, are these known to leak from the oil pressure sensor at all?
