7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Search the site to see if someone's done a valve job. I remember seeing one... Not going to be easy on these engines... I don't believe it should have hurt the Pistons any,but when you have the heads off you can inspect them. While you have the engine opened up go ahead and change the center water pipe. Also remember when you do the valve job you will be replacing the notorious valve seals. So that will take care of another problem that creeps up at 100,000.

I might be wrong, but my guess is that the previous owner had a DIY go sideways. It's not common for these engines to loose timing without intervention. Most likely a valve stem job (with cam removal) or tensioner repair that went wrong.
