My first choice would be to close the thread and delete it, but if it has to stay I would change the title to "ALL 2008, 2009, 2010 C63 have affected headbolts. Some early 2011." Check here 2008-2011 is far worse than the current title unless you are just joking.

Hello,
As many of you know, I have been providing Datacard info to many members interested in their build sheet, or to verify engine serial number.
I received a PM from a member today who indicates he has a "late 2010 C63". The Datacard for the VIN he provided shows a delivery date of 11/24/2010. The Datacard indicates the engine number is over 4,000 engines beyond serial number 156983 60 060658 where the new head bolts were employed.
Since we've believed that all 2010 and older, and some 2011s were in the affected range, I'm confused about how this one could be outside the range. I did a search to find out which digit in the VIN corresponds to the model year, but had no luck getting a clear answer.
Anyone have any thoughts on all of this?
Thanks,
Joe

Word of warning - My 2011 C63 with Engine 62768 does NOT have the revised headbolts. I was just in there the other night doing valve cover gaskets and I have the early version. My heart sank when I saw them as I should have been far outside the affected range. I also double checked the serial number on the block and it matches. This sucks, hopefully I don't have any issues, but at least I am aware now.
Yeah I even poked it with a pick tool in disbelief. Just a pocket of oil
All I can think of as to how this happened is either A) Mercedes is wrong... which I don't think is likely or B) someone has had this engine apart and put it back with new old stock headbolts. I didn't see anything in the MB service history that would warrant such a teardown. Could have been an independent shop but who knows.
I'll be pulling the splash covers off probably tomorrow as I get further along in the header install. I'll look for some witness marks that may signify the engine was dropped out. I don't see anything from above yet. But I wouldn't get the pitchforks and torches out just yet. Nobody is perfect in pulling/replacing an engine, there will be something someplace.
Did they update the valve buckets at the same serial number cutoff? I have minor wear on my cam lobes. May be another clue to this puzzle.

I had another thought.. is it possible MB identified one or more bad lots of the old design, but decided to redesign as well? This might explain why some old style bolts (not "defective") are in engines past the switch over.
