Most expensive repair ever?

My '07 550 has been burning oil for a few weeks now. It has 80k miles. No drainage on ground at home and I see gray smoke out the back on starts. I just took it in for a diagnostic at my dealer (who I actually like) and it took them a half day to find the valve seal guides are shot. They say part of the fix includes machining (machining what?)at a local shop and the total repair is 40 hours and 6-7 days for $6,200. Does this sound right? How much is a new engine? (and my extended warranty ran out 5 months ago) Could I save

can someone explain what 'valve guide seals' actually do? Why so much? Is it reasonable to think an indy shop can do it for 30-40% less?

I always heard transmission repairs were most expensive.
