I vote on leaving it alone if not actually leaking. They almost never leak. And my experience has been bad with replacing them. In the past 30 years I have put seals in just about every diesel engine you can imagine. I did the "while we are here" deal on the rear seal on my own truck and ended up with a leaker.
I have also seen a leak created at the seal plate to oil pan joint by the vibration and flexing of pounding in the seal.
If you are worried about it plug off the CDR valve and put no more than 3 PSI of air pressure in the crankcase by coupling an air pressure regulator to the dipstick tube. Check the amount of pressure by removing the oil filler cap. A small build up of air should escape. About like you blew into a coke bottle and then let it go. Now go over anything you think might leak with soapy water. Amazing trick I've used for years. Just don't over pressurize and create leaks....
