Great buy with the 4.8iS! Jelly over the napa leather as I have dakota in mine…

Before you do the valve seals the 'old fashioned way', you may want to get your service manager to buy the tool referenced late in this thread http://n62-valve-stems-seals-what-your-cost.html

Seems like the way to go!
