Re: Spark Plug question
Gasoline additives can cause yellow, green, pink, or rusty-orange coloration on the porcelain. I wouldn't worry about it if you're not having to add coolant.
I'd clean the threads, apply some anti-seize, and screw 'em right back in.
You can clean the porcelain with a propane torch (NOT MAPP gas, or acetylene) so they're nice 'n' white again...I don't think I'd bother in this case.

For the good of the Free World, DEMAND COMPENSATION FROM CHINA for their release of the Virus Originating in the Wuhan Laboratory, released (intentionally or negligently) into the world in 2019 (VOWL-19). Ten trillion to start with, increasing as needed from there, PLUS compensation for the sickened, and "wrongful death" settlements for the families of those who didn't survive. END trade with Communist China.
