This is the v10. There is an oil leak that is dripping on the front aluminum looking pipe that is right underneath the fans. It is coming from around the top, around the serpentine belt tensioner. Can you tell me what is there that can leak? Some possibilities?

Can you get a picture of the part that this oil is dripping on? More than likely this is an oil pressure switch dripping or something like this but seeing where this is coming from will surely help us figure it out.

I am attaching the info below on the switch so we need to start with this, but I think seeing it will help.

If we can't then we are going to need to put dye in the oil and then clean it off to see where it is coming from.
