    It looks like there is oil leaking from the upper part of the vac pump on my Jimmy. I've noticed it down as far as my trans pan now. Is there an o-ring or seal that can be replaced or will I have to replace the whole thing. I haven't taken it off to see how it is assembled yet. Just looking for some advice on what to expect. Thanks-Russell

    I saw in my diesel tech manual that there is an o-ring that is to be replaced when tha vac pump is taken apart so I guess that's the prob. Is there anything I need to know before hand about R&R or the vac pump. Any help is appreciated.-Russell
