Oil leak pretty significant

[nicpon]

Ive got a 2006 3.0 with 140k miles - pretty baby. Just recently started to see (probably has been happening for a while just not dripping) drops of oil in the garage and on the last visit at the dealer they advised me of leaking oil filter housing gasket, which i didnt fix at that time. In any case i wanted to change the gasket today, but upon my inspection the oil leak that im concerned about isnt coming from oil filter housing or at least not in my opinion.


Let me ask a question first and then add few more details on my troubleshooting. What are the typical oil leak places for this milage/year/engine?

Now my troubleshooting...
I took out the intake, air filter housing to get a good look at the oil housing. Its little oil dirty, but the dirt doesnt seem to be fresh, definitely some small leak, but not the amounts that im seeing under the car.
Then i took off the reinforcement plate and the padding as well as the plate is soaked, the driver side at the engine bottom is soaked with fresh oil too.
The problem is that the leak is happening above the pan somewhere on driver side, probably above the driveshaft and I cant see where. I cleaned up the mess a bit, ran the engine to see if new drops show up, but no luck. I looked with pinhole camera above driveshaft, but cant tell still where its coming from. So, im hoping that thete is known common place were failure occur and I can better troubleshoot based on those?!

If someone has some ideas on spots to check do please letme know too...

Thanks
