Engine oil pan and trans leak question
I have just under 15k miles and I am doing the second oil change on my 17 Fusion Sport (I learned from others to stick with a 7500 mile OCI with EcoBoost/GTDI regardless of the type of oil used due to soot contamination and timing chain wear), and I had wiped clean the oil pan and transmission last week so I can keep an eye on what seeps out. I noticed that the only area of my oil pan that shows signs of leaking is that rear most bolt near the drain plug, passenger side - nowhere else on the pan do I spot any seepage/leaking. The top of the bolt in that recessed part of the pan is always covered in oil. There's signs of oil seepage on the felt under-body cover but nothing that is dripping.
My transmission shows signs of some weepage. There's a light layer of ATF on the bottom rear of the trans. I wiped it clean last week and saw it again this week.
My axle seals and PTU seem to be ok, no signs of gear oil.
For those that kept replacing oil pans or had trans/seal/PTU leakage, how did your situation compare to mine? Am I expecting more or bigger leaks in the future?
PS - I used 6 qt of oil last time and I got out maybe 7 qt of fluid. I thought it might be excess fuel but the oil actually smells very "clean" for an EcoBoost/GTDI engine. My coolant level hasn't dropped by 1 qt and the oil doesn't look like a milkshake.
