All 2010 and older and some early 2011s are affected.

Hey there. I've been lurking for a bit and finally decided to get serious about picking up an E63 AMG. The car I'm looking at has a VIN of WDDHF7HB8BA366727. Would I please be able to see if it is affected by the head bolt issue? Thanks!

Not affected..

Hey everyone,
considering buying another mercedes. It's a W164 with m156 engine. I did record some videos at dealership. Do you hear the ticking sound or it's me just being paranoid about the header bolts/lifters issue?

Does this engine sound OK?



Thanks in advance!

that engine sounds good with no ticking. also sounds low miles.

Don't let paranoia set in, there are more engines with miles and no issues than engines with issues. If you are really following your ear on this to check, cold starts after they are sitting for a few days are a better test on ticking. Good luck and enjoy it without concerns.

So I had the headbolts replaced as a preventative bolt replacement. C63 2010 model with 100,000km well maintained car. The 20 bolts were all fine, there were no cracks, no real pitting in the bolts the photos look bad the bolts were totally fine.
Only things worth noting were the 5 of the bolts from the 10 on each head had stretched the very slightest as shown in the photo below, also
when drying the bolts to photograph them there was quite a bit of crud on the surface of the bolts and bolt threads meaning some would be left in the head from removing the bolts so when your pulling them out dont muck them in and out much and clean out the head as best you can.

From 1 head side there were 5 headbolts that were shorter and 5 headbolts that were stretched by a tiny bit as shown in the gap in the photo

Old thread I know sorry
 

can you help me out on checking mine. Thank you WDBUF77X88B274041

Any amount of checking on the forum would have told you that you have the old bolts. You have one of the oldest engines still out there.
