Smoke and Oil Loss
There was a point I did a lot of upgrades and then Oil loss and black -> grey smoke started to be very apparent out of the exhaust only on WOT - high rpm and generally on the throttle release.
This was heavily apparent after I had PPE headers installed.
Then because the fuel smell was harsh I installed GESI Cats
Some of the smell seattled but I still could not drive with my windows down without my clothes smelling like exhaust fumes.
Then I was unsure if I was running heavily rich so I decided to go with the RR Racing tune + Larger intake box.
Seemed like I felt the power increase but the smoke on wot / release @ high rpm did not disappear. It is a huge puff of smoke behind me - covers my back of my car apparently is what other friends told me.
I constantly checked my oil separator to ensure it is not full or what not.
Not sure if it is in my head but feels at high rpm there is just a constant decline of power.
There is no white or dark smoke at idle or normal cruising.
Since these upgrades I must have driven 20,000 miles?
Losing about a quart every 1000 miles.
Intake Valves, Rings? other suspicious things? - should I do a leak down test?
Before all these upgrades I did have "some" oil loss but maybe over 4-5k - it would be 1-2 quarts

Not sure how many miles you have on your F, but I would look into your valve cover. I more recently started noticing higher oil consumption but around 1qt every 2-3k and also occasional small amounts of smoke on WOT. Mechanic took a look last time he changed the plugs and said for sure i have a small leak. So i gotta take care of that soon :/

Two mechanics checked for leaks. No drips. No signs of any leaks.
seems like its burning or firing straight out the exhaust at high rpm
Currently at 215 k miles
