because I still have to drive it for a year or so - I don't want to have crap parts on it. with the way I drive, a junyard box will be gone in a month or so. As for "not being able to find" the power steering cap, the manual for the e46 doesn't even list one as existing, nor point out where it may lie under the hood. Neither me nor my dad could locate it. And we are far from being mechanically disinclined.
