2008 Tundra 5.7 2wd Oil Leak

Alright Tundra gurus, I need help. This morning I noticed some oil build up on my cross member. I recently had my extension housing seals changed and before they were changed the entire undercarriage was covered in trans oil. Since then most of it has dried off but not the Crossmember area. I wiped the area with a white rag and then wiped my dip stick with another white rag for comparison. They match as far as color on the two separate rag will add pictures here shortly. Any idea what the problem could be. The oil leak has mainly been onto the crossmember and no where else. Any and all information thank you all. Chris

UPDATE:

I did some looking around the engine bay and found that the hose that goes into the valve cover looks to be the source of the oil leak. The bottom of the hose where the hose clamp connects to the hose has oil running down the side. The oil runs down from the bottom of the hose and down the valve covers onto the cat covers and then down to the crossmember.
