    I think they come in most full gasket sets... Is it the copper colored one? I've also seen a plastic (usually white) one in there as well. Any input as always is appreciated.

    You talking about the oil drain plug, or the oil pressure regulator nut?
    If the regulator mut, yes it USUALLY a white plastic washer.
    I think the original MAY have been a copper washer, I know the washer your talking about in the full gasket set, I never used it, ‘course I never checked to see if it fit anything either:p

    My SP timing cover that I never messed with (severely pitted water pump cavity) had no washer. If it leaks ig I can add one of them universal washer dealies from the parts store. They're kind of thick... Would it change the preload on the spring?

    It will change the pressure ever so slightly, but not enough to worry about.
