While I'm not a mechanic, only mechanically inclined as a do-it-yourselfer, that looks more like a gasket issue. My '14SE has 151K miles, is not a DD, and 3.5 years ago, I paid $32K with 136K miles on it. Drove home from Dallas 515 miles non-stop, except for 1 gas stop. Didn't know about Fuse 27 at the time, but found out soon after, luckily close to home. Replaced that myself easily for $30(Amazon) and (YouTube). I changed my differential cover with one from Summit Racing (#SDH-10023539) and gasket (LUB-LLR-F975) at 146K only because I didn't know when it had last been serviced. I chose that cover because it doesn't have to be removed to drain the oil.... And the Safety Recall Notice 24S37/ NHTSA Recall 24V444 was just performed 3 weeks ago at the local Ford dealer at no cost. Took about 45 minutes. You've got a nice truck in spite of the tire shine that should give you years of pleasure if you maintain it properly.
