E70 4.8 Oil Leak- Help!

[Boosted_s52]

Info- 08 x5 4.8i with 95,000 miles. Owned the car for 5 months now.

So this week I changed my oil cooler thermostat gasket (alternator bracket for non oil cooler cars).

Question is the car is still leaking oil. It is not an alarming amount or rate, but still noticeable on the garage floor. Ive noticed oil dripping from the bottom of the alternator and dripping from the diff cover, same as it was before I changed the gasket. Any ideas?

Not sure where the oil would be coming from since there is not an "alternator bracket"on here because of the oil cooler. Possibly leaking from above.

My thoughts on possibilities: Valve cover gasket, upper timing cover gasket

The oil thermostat gasket was not cracked or have an evidence of leaking, however, it was rock hard.

Would like to give a shout out to gregg3gs and bdcanetti for their write ups. Made life a lot easier.

I will post pics below, they are prior to removing the Oil cooler thermostat gasket.

Thanks for any insight provided
