Has anyone encountered anything like this. Video at around 47 seconds in shows the best view of the leak. I've never had one of these off so curious to know if that round end has a seal. It's hidden behind the alternator bracket. Truck only has about 60K miles. Out of the scope of warranty of course.

From the video, unless I am mistaken, it looks a lot to me like it is here...

   


That is the lower front corner of the oil cooler housing (shown upside down in the picture Nilao provided a while back).

Maybe someone who has had a few of them off can help better. I have never had mine off yet.
