From the oil im seekng I wouldn't image that it would be from anything else. On my engine it is very hard to see the pumps so I cant be sure but im going to have the chargecooler off which sits above the Intake manifold. While I have it apart would it be a smart idea to change the O rings anyway? Im almost certain that they've never been taken out.
Well, what if you have a crack on your gravity feed hose that expands as the hose warms? What if one of the connections of the small steel lines at the pump body was not sufficiently torqued and has worked loose, causing a leak? [The latter happened on my Silver Wraith II.] That's the kind of thing I'm talking about. You need to be certain that the leak is coming from around the pump body before you know what you must do, versus might want to do, next.
You will get advice to change the O-rings from many and not to change 'em from many as well. For myself, I never mess with a functioning system, particularly static O-ring seals, if nothing's malfunctioning nor very likely to malfunction. You may find that one of the two pumps is leaking. If that's the case you'll have to change them on that pump. You can then make your own decision as to whether you think it's worth it to pull apart the pump that's not leaking. There are lots of things (like replacing the thermostat, and [for me] not with the one from Crewe Original) that fall into the category of "do it while you're in there because it's going to need to be done anyway, and it's hard to get to it later," and others that, in my estimation, are not. You will have to listen to the advice you get, weigh that based on what you already know and what you learn during fixing what you determine you must fix, and then proceed according to what your gut and your brain tell you. There are no "absolutely correct, for all owners and in all situations" answers regarding how to maintain your car. I openly admit that I'm of either the very conservative (or wildly cavalier, depending on who's asked) attitude that you never touch a functioning system unless there's a reasonable probability that a component could fail in normal service. I've seen a lot of problems created by the "Well, you'd might as well do it while your in there" philosophy, particularly on things that just aren't likely to fail. Every time you tear something apart and put it together again you're introducing variables that you then must monitor.
I'd certainly consider whatever those who've actually "been there, done that" on a car with a setup that's similar to yours have to offer. Ladies and gentlemen who fit that category, please chime in!!
