Diesel in oil....i don't have to tell you what that does to a engine.
As to the cause.....there are guys on here who know the series 60 real good but they are sleeping now.Rideandrepair and jvillarreal82 Thank this. -
I’ve got 3 trucks over 1.9 million miles with the series 60 Detroit 12.7. I’m no mechanic but I believe one of the main reasons diesel goes into the oil is when you idle at very low rpms in cold weather. You need to bump the rpms a tiny bit. Otherwise all the diesel won’t get burned up and will leak through the sleeve which is not a cheap fix. I could be wrong though because it’s also usually an injector. But with the cold weather it’s something to think about.

YES! Just happened to me. I had scheduled to get unto Detroit and get it checked out. I don't idle so that wasn't the problem. It shut down on the highway. I checked to see if coolant or oil, and the oil on the stick was about 3 inches above the line. All injectors were bad, but number 4 plunger was stuck open. It needed bearings too.
Get it checked out pronto!wore out, Rideandrepair and jvillarreal82 Thank this. -
Check & see if one of your injectors is leaking. I had that problem fixed & the green monster was ready to run strong again. I hope all goes well for you.
