2002 Powerstroke Turbo Seal Leaking

I have a 2002 Ford Excursion with a 7.3 Powerstroke and the turbo oil seals seem to be leaking. I have inspected the HPOP to make sure both plugs and hoses are not the source of the leak and I can't see any cracks in the turbo sleaves. So I think the oil o-rings on the turbo seem to be the source.

Can anyone give me an idea of how hard it would be to replace the turbo o-rings? Do I just need to completely remove the turbo and re-install it with a new gasket and o-ring set?

Any help and/or web resources that you can pass along are appreciated.

The turbo has to come off. If you are talking about internal seals, it has to be rebuilt. If you are talking about an external leak, it is the turbo pedestal that has the o-rings that leak. Here is the best place to buy them. Also, about halfway down the page is a link to a .pdf instruction sheet.

I found this article that I'm going to try to use to remove the turbo and pedistal for the o-ring replacement.

It looks like the one I referenced above. In case you didn't see it (its buried in the page on the whole kit of o-rings), here is the direct link:
