How screwed am I

[Darkhorse99]

Is the gap exactly the same from Factory on all six plugs, curious especially from number 6

All very close. Within 0.01.

Did my first plug change today at just under 28,000 miles. All plugs but one (#6-closest to firewall on passenger side) looked about how I thought they would. How bad is the #6 plug covered in oil and what could be to blame? Any experts on here?

Do you have oil loss? If so, check this notification from Ford:
May 14 2019 8236 - 2017-2019 F-150, 2018-2019 Expedition/Navigator - 3.5L EcoBoost - Excessive Oil Consumption - Built On Or Before 1-Apr-2019
Some 2017-2019 F-150 and 2018-2019 Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine built on or before 1-Apr-2019 may exhibit excessive oil consumption with or without diagnostic trouble code (DTC) P0365 and/or P0369. If there are no visible external oil leaks, replace both valve covers.

Thank you. I had to add a quart between oil changes.

Don’t thank her, she’s trolling you.

All manufacturers have oil consumption memos for all models. They document from the factory to the dealers what level of consumption is ‘acceptable’ under the warranty and if there is any remediation available and under what circumstances.
