Re: Super Duty plugs PITA
When you do replace them, be sure to dab the threads and the taper seat with a nickle-based high-temp anti-sieze compound.
In the "good ol' days" when you changed the plugs every 10,000 miles (or at least pulled 'em, cleaned & regapped 'em, and put 'em back in), stuck spark plugs were a rarity.
These days, it's 100,000 miles and several years between changes.. by which time they're stuck real good.
"My diesel ain't got no spark plugs", he said smugly.....
