I don’t think you meant “dichotomy”.
Fair enough; it was the closest I could get, out here at the station kitchen.
If, like you, my machine was coming out of a servicing with a plug with cracked ceramic or any other physical damage which had showed when I taxied to the fuel bowser (righteous indignation moment), my suggestion would be: negotiate to have the rest replaced with known good ones, preferably new, but seconds would do as long had atleast as much time in service remaining as mine.
If your near Cable Beach any time this season, PM for a sherbet, could talk over beers looking out to the Indian Ocean.
