Hello and thanks for everyones imput on the vacuum pump problems. Well I finally got the screws out but I busted off two of the heads - and after all of that I found out the I had the wrong repair kit because I have the piston type. Put it back together and the pump did not have a good seal so it would not shift out of first and it would not turn off. I figure hell I want to save myself from buying a new pump so I tried the kit - did not work - so - I call a couple places and found one for 65.00 - good idea? Anyway had to remove the radiator and outher things but finally got the pump off and now I am trying to put the new one on it does not seem to want to go. My question is - it seems like the bolt that is underneath it on the engine it blocking it from goin on - not sure what that bolt is but it has a 1/4 inch washer ( maybe less than a 1/4) steel -almost looks like a bearings but it is not. And the bolt is not screwed all the way in I loosen it and it seem to be only in a turn or two - so the washer could move back and forth. The bolt is threaded all the way - should this be flush tight anginst the washer?? I am going to try to take a picture tomorrow - o ya - when I remove that bolt oil seems to come out?? this might help.

Thanks in advance for your help
