Uh, no. I remember doing that sometimes when changing sparkplugs (glad those days are gone), but it certainly wasn't a "do it or else you're screwed" kinda thing. Once I get that manifold and servo off, I'll probably pull them all and use anti-seize at that time.

Btw, just finished the Diesel Giant "complete car filter kit", sure feel a lot better knowing that's all done.
