Clearly it doesn't. I was referring to the whole process if this doesn't fix it and he has to keep going back and forth to the dealer...

 

Ok, let us know how it goes once its back.

 

That's right about where my 30K mile 2009 C63 is. 'Bout a quart every 5-6K.

 

Any update on this? Did u get the car back?

 

Supposed to pick it up this afternoon if all goes well. They did let me know that MB is giving me an extra year of warranty coverage, so that makes me feel a bit better!

 

Oh sweet, that is good.

You gonna drive the **** outta it?

 

That's the plan, I will update later tonight with my impressions...

 

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!

 

Glad you've got your car back....I guess it'll take 4/5000 miles before you'll really know how its going.
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.

 

Any update ? I had check oil engine 1000 after I had my oil changed. I just got the car and I'm a bit worried...

 

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.

 

FWIW, when my M5 needed a new short block (and then two new heads) my dealer told me they considered two techs out of fourteen qualified to rebuild my motor. They both had been building race engines as a second job for years.

 

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.

 

Thanks for pointing out the obvious...I'm purely stating facts. You take your car to the dealer to have your motor rebuilt and trust me very very few of the licensed techs would do that job willingly. Especially considering under warranty it probably pays the **** for time. If you haven't worked in a dealer shop then you don't know. It's a high risk job that will take time meanwhile you could be doing gravy job services and brakes all day. Apprentices get the **** jobs and this definitely classifies as one.

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.

 

So, what ever happened to the OP's car?? Was everything good after the rebuild??

I guess it's okay. He never got back to this thread

 

Free bump

 

Really helpful as always, bumping a year-old thread with nothing useful to add. Just clogging the forum with more uselessness. Expected.

 

I guess I'll just create a new thread to not bump old threads.

 

You’re going to create a new thread that just says “free bump”? Because it’s retarded to bump a thread for no reason. But carry on and keep doing whatever you want. We’re all here just to cater to you.

 

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...
