Regarding the PS reservoir cover on a '64 car, the shop manual says not to over tighten the wing nut, or else the washer will seal off the vent passage in the reservoir lid and cause noisy operation. I've also heard or read somewhere that a pressure build-up could result, causing the pump to leak. What I've always wondered about is this: With the steel flat washer in place, that little vent hole is covered up. And when you get a pump rebuild kit, you even get a rubber washer or two that go under the steel flat washer. Seems to me that in either case, you are effectively sealing off that little vent hole. So my question is .... what are we really supposed to do? I fear that without the rubber washer and too little torque on the wing nut, a leak may result. Or, the wing nut may work loose and maybe even fall off the stud. So, I presume I'm missing something in the interpretation of the manual. Or, is there more to the story, and I'm just missing out somewhere? Your input will be appreciated.
