I'm wondering if this picture is my front main seal leaking?
I just noticed it the other day when I was cleaning the undercarriage.
1999 Disco 1. 164k on engine.

 

It could be front main seal or cam position sensor. There is an O-ring on the cam sensor that will get brittle and leak. If you start the engine and look at the back of the crank and you see oil dripping then its the front main.

 

That’s pretty clean. Curious as to what this is:

 

Axle/diff breather line.
