Oil coming from Main Seal? Pics included...

[Diff Kraken]

Took my truck in for it's first oil change since I bought it in Sept. It has about 110k on it. Shop said they think the main seal is leaking, but they want to do a dye test to make sure it's not the valve covers. I see oil dripping- but this is after the oil change. The oil is dripping on the back end of the skid plate too. My thought is that a leak would much more likely be the valve cover bolts needing to be torqued down a smidge. Here are pics of the oil at the back of the motor. One pic under the front passengers wheel well and one from underneath. What do you guys think about the possibility of it being the main seal on a 2UZ-FE motor?

Wasn't able to find info on main seal leaks here on the 120 forum, but the 100 series forum has a few good threads on this shared motor if anyone is interested:

rear main seal?

After my 1000 plus mile trek to Moab and back, I now have an oil leak. Looking at it, it is behind the oil pan right where it meets the transmission. It does not look like the oil pan gasket, more like a seal (?) in between the oil pan area and the transmission. I will try to get a picture...
