Looking into solution for my friend.. This is a recently purchased 2013 e63 motor with about 47k on it. He's had it about a month. Was on a road trip and had check engine light come on and car went into limp mode. Plug in cylinder 8 was fouled. That being said oiut of town dealer looked with boroscope and there is scoring on cylinder wall and recommended replacement to the tune of 100k which obviously sounds insane. Car is being brought back to selling dealer to look at. My friend did say he had to add oil once or twice and he's had a puff of smoke on startups. Any idea how this could be caused? Are there known issues with this motor (rings, pistons, etc.)? We know its not a cheap fix, but is the motor worth rebuilding or even repairing?
Yeah, I was quoted $96,000 to purchase/install a new M156 from the dealer. The scoring looks BAD, not sure it can be saved.
As far as oil consumption and smoke at start up, common issues with an AMG. The question is how much oil over how may miles.
I agree on the scoring. Car was supposedly running fine though until the plug got fouled. Are a compression and leakdown test worth doing? It looks bad, but it's hard to judge from the pictures because its so close up.
hi..I am surprised, that there is no that much information on engines M278 and M157....In C63 I think your fried has M157...There is a really big problem with silitec coating on those engines..because I dont speak english really well, I wil copy here youtube link....
. If you click on the on the guy-Tasos Moschatos, he is from SAE, strange englisch spoken, but he is a real expert on those engines...there is a severel hours to watch only about engines M278(I have one in CLS 500) and about engine M157....What I can say-if somene use tunning on those engines, they dont last that long...also an oil change should be every 10.000 km, and it has to be MB aproved 229.5(not 229.51)....In my country-Czech Republic, one friend has that problem---wear out silitec coating, and the repair cost about 25 000 euros....nonsence..
2013 is a M157 not a M156. And the M157s have had that scoring issue quite a bit especially in cylinder #5. Usually doesn't amount to much, but sometimes you lose a cylinder
I guess I should be thankful, my dealer only quoted me $78k to replace with a new engine

The coil and fouled plug were replaced and the car ran perfectly fine again apparently. For how long it will is the question...
I don't know that much about cylinder scoring, just googled it a bit. The general (non M157 specific) causes outside of other major engine damage causing scoring downstream seem to be inadequate lubrication or cooling.
What's the root cause of the M157 cylinder scoring? For the M157s that have seen this issue ... what oils were used, or have extremely high IATs been measured? What tunes?
We have seen it all on those engines. Some of those engines are born with an "mistake" from the factory, there are 2/3 things that are causing failures, which we discovered in the past years. (the video that has been posted from Tasos, we are working together)
besides that, the OEM connecting rods fail in fatigue.
The prices are crazy that you guys get for those engines.
OEM M157 - with maximum 200 km I can offer for a total of max 18.000USD. (incl. turbos and all wiring)
Upgraded M157 - build by order depends on the internal parts.

So you guys rebuild M157 motors then? To customer spec no doubt?

Hello Scott,
yes we do, to the specs you want, ofc after so many years and +1000 of AMG's we recommend certain parts, manufacturers. We rebuild, upgrade, offering "almost" new engines too. (as i mention with up to 200 km only.)
You can have a look on YouTube, "Tasos Moschatos AMG"

Can you talk more about the engines with mistakes and what people should look at if under warranty?
I usually don't wish negatively on people but if the next 10 cars you bought had bad motors I wouldn't feel bad.
I don't get all the aggro. The OP's mate has owned the car for a month. He has already had to "add oil once or twice". That engine hasn't just developed the issue. I will bet the previous owner (and/or the car dealer he sold it to) knew full well the car had issues that in effect have rendered it an economic write-off. I feel for the new owner and would never wish the experience on anyone. However he is now playing in a game of lemon car "pass the parcel" and unfortunately the music has just stopped with him. And who knows what other expensive repairs lie in wait in a car that has more than likely suffered 7 years of neglect and 47K miles of abuse. He could get lawyered up and go after the dealer that sold it to him, with a claim for a full refund of the purchase price. But failing that he would be crazy to spend a cent on repairing it. So my advice remains the same: get rid of it and move on.
It's not aggro. Could've been the new owner, could've been the old, that's not the debate here. Up front, it just sounded like the tone of your post was to unload the problem onto someone else sort of hiding it. However, perhaps I just misunderstood and you're just saying get rid of it and take the loss now. So my apologies, but to me it came off as just unloading the problem onto another unsuspecting person and reading it over a few more times I'm thinking you're just saying cut your losses now.

None at this time. But if I have an engine failure, I will reach out. Better to spend less money and build what you want, then give Mercedes $96K for a replica of the engine that had issues! You have to pay to play!
