Is this what a lower crank case oil leak looks like? 2003 DTS

I have already replaced the oil filter adapter gaskets. Next I will replace the oil pressure sensor and oil level sensor.. But if you look at the photos you can clearly see oil residue above the sensors. So I don't know it the sensors are leaking. Perhaps the oil is just running down coating the sensors with oil.

What do you think?

Thanks, Brook

That amount of seepage is minimal - you can buy a heck of a lot of oil for the $2,500 it will take in labor to replace the seal. You might be able to carefully try and tighten some of the pan bolts - there's a specific torque setting because the pan is a structural part of the engine. Some have attempted to clean the oil with solvents and use epoxies and glues on the seam. That's not even close to a proper repair.
Do you have the info pertaining to what each bolt should be torqued to?
S&B, Have you noticed much of a decrease in your bottom end oil leaks since you had the adapter gaskets replaced? If I remember correctly from your other thread you had 3-4 different shops look at it and got 3-4 different answers on what was leaking.
Big diffrence since I got the oil filter adapter gaskets replaced! No more smelling of oil while in traffic! After a new oil change, no puddle of oil in the driveway!
