Some reason I can't quote your post.
Noticed oil on the filter after an oil change after 60k miles. Thought at first it was residue. No oil ever on the garage floor Wiped it and checked a week later and there was a drip. Filter was tight but I thought just replace the filter to make sure if it had a defective gasket. Made sure to wipe down the area with more care etc... Still a drip on the bottom of the filter.
Took it to Ford, they looked it over, nothing first time. Still was occuring, so took it back 2 more times till they looked it over in more detail till they realized the oil was coming from between the Head and the block.
So, they had a Ford engineer come out, make sure the truck had no signs of over heating etc... Diagnosed it as a porous/bad head. They figured out that oil would leak out when the engine was cold and then when it got warm it would expand ever so slightly to seal it back up. Never noticed any noticeable losses of oil and changed the oil back then every 3-4k miles so never ran it long distances between oil changes.
The engine tech we knew at the dealer was requesting a new shortblock too based off what he saw from damage from the pistons,forget if it was related or just found when they took it apart, but Ford only authorized the head change.
Also replaced the water pump then too as they noticed it was showing signs of possible failure.
I had more pics of the teardown but switching from Android to Iphone scrambled the older pics around as this was in ~2017 and it's taking a while to scroll through them all.
