M156 head bolt problems
#226
Here's an interesting treatise I bookmarked some time ago. It's well worth reading about the engineering that went into the M156 motor. I recently went back to it and there's an interesting addendum (which I won't quote beyond the opening).

2012 Addendum: Time is beginning to reveal a few secrets . . . . . . . .
Early M156s have serious top end issues. Early as in through engine number #60658 (those are the last five digits of the engine number and this issue impacts all 63 engines through the early 2010 vehicles). "Issues" as in plural.

Do we know what the general cost would be to preemptively install the Weistec/ARP head studs, and if it is pretty much guaranteed to resolve any likelihood of having any of these issues in the future?

Total cost of parts + labor should be around $4-5k, from what folks have been saying on the board.

What about the other problem of premature wear to the M156 engine parts as in that current NJ lawsuit? Are you taking care of that at the same time?

Weistec hooked me up with SLS valve buckets so I guess the only wear I will get will be caused by the 1000 odd hp I will be pushing.

08' e63 engine problem
Looks like my 08' E63 is now on the list as another headbolt failure. It was just flat bedded to the local MB dealer this morning, with all the exact same signs. I believe my engine may also be hydro locked up. I have 54k, and no warranty on it, so I have my fingers crossed that the MB dealer will "do the right thing" and help me out with this. I think I would be ECSTATIC if I got off paying $5k with a 12mo warranty, like morganb did...

My 08' E63 was just diagnosed with the dreaded head bolt failure. My engine hydro locked and I am awaiting a decision from the Mercedes dealer (I am out of warranty with 53k on it, and 6 months over).
My question is for Mrtazzy: if Mercedes is unwilling to do anything for me, would you be able to recommend anyone in the states to do the type of repairs you so thoroughly did, and around the same price? I'm in the Ohio/Pa area, but willing to pay to have it taken somewhere within a few hundred miles or so... You can PM me if you prefer that way. Thank you for any help you can give me... I'm really bummed out about this with it being my first Mercedes....

Mate, I have seen you commenting on this "issue" many times.
I have also asked the question about the so called "class action"...ie, what is going on, what is the up to date situation, is there indeed ANY class action happening at all, or is it just a big "beat Up"?
I only ask the question, because I asked a month or so ago whether anyone had any info on the "class action"........NO-ONE relplied!!!!....So, maybe it's all "myth & hearsay"?
So, as you've made several comments on the issue, I thought you may know some FACTS?
Cheers, Pickles.

Mercedes-Benz Faces Class Action Lawsuits for AMG V8 Engines
BY ADMIN – OCTOBER 25, 2011
POSTED IN: AMG MARKET NEWS
For those of you that have not heard by now, Mercedes-Benz is facing a class action lawsuit for alleged defects in the M156 V8 engine installed in numerous AMG Mercedes vehicles. You can read the class action complaint filed in New Jersey here.
According to the lawsuit, the class action may affect all current and former owners and lessees of 2006-2011 Mercedes-Benz C63 AMG, E63 AMG, S63 AMG, CL63 AMG, CLS63 AMG, ML63 AMG, CLK63 AMG, R63 AMG, and SL63 AMG models equipped with AMG M156 6.2 liter V8 engines.
The class action lawsuit alleges the V8 engines in several AMG vehicles have underlying problems that make them prone to premature wear, causing major engine damage and sometimes total engine failure.
Los Angeles resident Cedric Chan alleges in the Mercedes-Benz AMG class action lawsuit that after obtaining his AMG he experienced problems with loud ticking noises under the hood and a drop in oil pressure. The lawsuit suggests the ticking and drop in oil pressure was the beginning of the AMG engine’s destruction. The apparent problem according to the lawsuit is that the defective AMG engines are manufactured using soft camshaft metal that is improperly heat treated and/or improperly offset, making the camshaft prone to premature wear. It appears Mercedes-Benz was somewhat aware of the defect since at least 2007 when a service bulletin was released. Service bulletin S-B 05.20/20b involved parts relating to the camshafts, including the camshaft adjusters and authorized replacement for at least some adjusters; subsequent revisions to the service bulletins include P-B 05.20/20a and T-B 05.20/21a.
Due to the premature wear of the camshafts, the camshafts, valve lifters, camshaft adjusters, valve tappets, gaskets and bushings all have to be replaced."The cost of replacement is thousands of dollars, which was passed on to Plaintiff, because Defendants did not issue a recall for the defect, even though they knew it to exist."

Yes, I've seen that...but that was almost 18 months ago!!!
I was looking for the CURRENT situation.....I mean, what is the CURRENT situation?......if there's no news at all, in all this time, then maybe this "case" went nowhere?
That's why I was asking, does anyone know what's happening NOW?
Thanks for your reply, Pickles.
