2006 6.0 leaking from back of the engine , clear fluid

Agreed with @bismic. Gonna need to pull & inspect/change that injector to find root cause. Check your oil level too, and change it if it's overfill. Depending on how it failed, if you have fuel leaking from an injector, it's quite possible some of that fuel could have leaked past the rings and contaminated the oil.

The fuel rail plug on the back of the head is leaking. It has a o-ring on it that has failed.

Good call...forgot about that! Should be able to see that plug with a mirror to confirm, right?

Oooooh that's a fun one.
Just check to make sure there's nothing in the valley first. A leak there could drain back.

On a side note - @kaya it's good to see ya back! It's been awhile!
