Can someone help diagnose this oil leak (photos)
I have a very slow oil leak. No oil stains on my driveway. No noticeable reduction in the fluid level between oil changes. But when I get underneath the car, its all over the place.
looking from underneath, it looks like the oil is coming from the area right above the oil pan and the transfer case -more towards the center of the car. The oil return line is clean and dry.
Below are a couple of photos looking from underneath. You can see the oil pan and xfer xcase for reference.
Any ideas?

I have this same leak. When I found it, I changed the head gasket right away. The gasket was fine, and I still have this leak. I do have arp head studs that were on the car when I got it, so I'm not sure they were installed correctly?

99.9% this is a result of installing the headstuds with the 1x1 method. I have seen it first hand at least 10X and heard of it dozens of times. Do a search on head studs and you will find a lot of info on this. The bad news is that most likely it can not be stopped even if you crank down a bit more on the head studs. The good news is that it is harmless and does not get any worse than it is right now. I knew better than doing the 1x1 method but I was too lazy to take the head off and I ended up with the same oil weeping down the back of by engine. I am taking the head off next week to do pistons and rods so hopefully I can finally stop this leak at the same time.

If it its the headgasket why does it always happen on the back of the motor? Mine is doing it to. If i reach to where the head meets the block, i don't feel any oil there, but there are a few plugs and a oil sending unit back there i just can't see well enough to see where it is coming from.

When you pull the original head bolt out the threaded hole in block will fill with oil,in most cases and if you attempt to fully install and tighten the stud that you are putting in it will only screw in so far then it tries to compress the oil that has filled the hole and you will not fully seat the stud resulting in IMPROPER installation.It is very important to blow these holes with compressed air as much as possible to get all oil out of hole before installing new stud.
