I did ask that and it appears that the walls need to be really messed up before they will replace the small block (i.e. scoring). The service manager told me that of the 12-15 63 motors he has had to rebuild in his time with MB that non have come back and non had the small block replaced. Not sure I really believe but that is what he said. So I guess we shall see. I hope to have the car back beginning of next week.

So I have had her back for a couple of days and so far so good. I don't notice any issues. I will update if anything changes and if the oil consumption continues to be a issue. Thanks to everyone for all the advice!

(a)'12 C63 P/P, LSD, 19" m/spoke,comfort pack. (b)Astra SRI.
Anyway, around that time, you could try a couple of things to see how she's going:
1. Accelerate hard up to say 6500RPM, & have someone on the side of the road check to see if there's any blue exhaust smoke.
2. Do the same, accelerate up to 6500, then take your foot off & let the car slow to say 2000RPM, then accelerate away again, & see if there's any blue smoke.
Both of these methods can visually help to ascertain if any excess oil is getting into the combustion chamber.
Cheers, Pickles.

Engine braking will generally yield higher oil consumption. Id bet that the guys who are burning more oil than others engine brake more than the guys who burn less. My M5 was the same way. Engine braking every opportunity i got netted me a liter of 10w60 every 800kms.. dropped engine braking and i could go about 4-5000K per liter. Mine just loved oil.
Rebuilding engines at a dealership level is not overly common anymore. At the end of the day Warranty will be paying atleast 15 hours to pull the motor and strip it to a short block state. At that point there, it will either go one of two ways, it requires a motor or will require more labour to dissassemble and repair. Even in that case they throw pistons in it, still burns oil, now they have to eat the 20+ hours of labour plus they end up putting a short block in it + labour anyways. This is true for non hand-built engines.
I am personally surprised, i would have figured being an AMG hand built engine they would have a AMG head tech fly down there to do the tear down and inspect. Or at a minimum call for a short block. Personally i wouldnt be happy with anything less than a short block BUT at the end of the day the money is not coming out of your pocket and if it fixes it then its hard to complain really.
Rebuilding a motor isnt for the average DIY. But at the end of the day, this engine isnt something from 100 years in the future, it still follows the same principles as your traditional overhead cam chain driven motor. Sure clearences will be tighter and technology has changed with regard to variable valve timing. But some of you guys are making these things sound like something from nasa. I dont know about your techs in the states, but a 2nd year apprentice in Canada would be "certified' to rebuild your average motor.
Anyways good luck to the OP hopefully it fixed your problem. I am curious to the outcome. If the walls werent scored and they werent out of round, then its very likely the rings were the cause. Was there any mention of the valve stem seals being replaced?

Dont's settle for anything less than an new factory shortblock where locals (try) to assembly the heads. Letting locals fit new pistons is asking for trouble. Best is a new engine.

I am in Canada and they have Germans working at the dealer here that do most of the AMG stuff... But its an AMG performance center I believe....
I know for a fact that the dealer would only assign a rebuild to qualified techs and not to an apprentice with 2 years haha.

That job would be best going to the shop foreman but just remember you don't necessarily get to choose who works on your car regardless of what the advisor says.
Like I said I'm really surprised you weren't given atleast a short block, if I was the tech working on it I would have said the walls are scored beyond repair and requires a short block. Try help the customer out. But if rings + pistons fix it who cares. If there legitimately is nothing wrong with The block and rings+ pistons fix it just drive it. Your mileage was pretty low.
Good luck to the op. keep us posted

A Mercedes engine depot is one thing, a typical dealershiip is another. The ASE cert in engine machining is a theoretical test which is good, but no guarantee/ What about proper measurement of the cylinders- proper bore gage avail? How about glaze breaking on cylinder wall ? Doing it with a 1/4" drill motor and stones? How does the tech get the grit and metal off the bore? Does he pull the pan and wash? Who fits new pistons/pins? How? Who determinse what was really wrong with the factory assembly? This is all done while hanging over fenders?
There's a reason why "crate engines" are a good bet. No loss of learning and proper facilities. Not rocket science, but should bee seen by dealerships as beyond most line mechanics cameo efforts. IMO

Dealers typically sub out machine work for engine repairs. Our local machine shop does a lot of the work for Honda, Toyota, Nissan and MB.

if you can't see the value for me to bump this thread, and that's your opinion which you're entitled to, maybe the better move would be for you to just not reply to me...
