C63 valve train components
Hi all.
Can anyone tell me for certain whether the C63 m156 engine recieved updated valve train components from the SLS m159 engine from the factory? I've read some post saying yes and others saying no. I know the recommendation after lifter wear and lobe damage was to use the m159 components but I'd like to know if this ever became standard on new builds.
Many thanks in advance!

later engine got an updated lifter design to prevent bleed down. I'm not sure when they did this. I want to say it was sometime in 2012 or 2013 but I can't be certain. When I did my headbolts I had the updated M156 lifters put in. the only upgrade you could do would be to put M159 BS lifters in. those have "more anti-friction coating" and I think are lighter. For a mostly street driven car, the updated 156 lifters are fine.

All P31 have the upgraded internals, and crankshaft
"AMG P31 Development Package (2011-2015)Edit
In 2010, Mercedes-AMG introduced a new "AMG P31 Development Package" for an extra $6,050, which ups the power to 487 PS (358 kW; 480 hp) compared to 457 PS (336 kW; 451 hp) for the standard model. Top speed has increased to 280 km/h (174 mph). When equipped with this package, the C63 AMG features a revised ECU and crankshaft, as well as rotating assembly components from M159 engine found in the SLS AMG.

Relax with the eye roll. My mistake, I didn’t throughly explain my asnwer which has been answered in old zombie threads before. Any m156 2012+ has updated buckets and headbolts. Internals depends on Pkg. And, even early PFL P31 shared SLS components, except for valve buckets and headbolts. Pretty simple search.
Hence the eyeroll
Not being rude. More sarcasm.
Anyway.... Let's progress.... Question answered for OP

Unless you believe Tasos. I think he has taken apart a P31 on video and showed that some of the so-called upgraded parts actually weren’t...

The lifters are of a new design for everyone, M156/M159, rolled out at the same time. If you search my posting, I looked up the part numbers. I think I saw the cut off was in 2010. The only different ones are the M159 black series.
The rest of the rotating assembly did not interest me as I'm not going to replace it.

Just look at my postings about the lifters. It's all evidence based (part numbers). If part numbers are not good enough for you, ask the parts guy at the dealer, he'll look at the same software and give you the same answer.

Ok:Looks like there are 4 series of SLS/197.Perhaps they had a facelift too.
The tappets are A 156 050 02 25 and A 159 050 00 00 for code P98 (black series).The part numbers stay the same through the SLS 4 production series.
for the base pre facelift C63, the tappets are: A 156 050 02 25 (this is for my 2010, by the vin number),
let me try for older ones, by the model:
OK, by the model, there used to be an A156 050 00 25 and there's a big note that it was replaced by A 156 050 02 25. there is no different part number for the C63 Black series.
Under my opinion, the tappets should be matched with the cams. If the part number of the cams for the SLS black series is different than every other cams, then those tappets matched to say a regular C63 is a case of try and see.
In sum, there are three possible tappets: The ones you have if you have a 2008 or 2009 C 63, the ones that everyone else has subsequently and the SLS black series ones.

It's the EPC.
The way parts software works (or microfiche before that), is that parts are substituted.
Depending on the manufacturer, they have substitution codes (1,2,3 or A,B,C).
Just like in accounting, there are audits and they're not allowed to cook the books.
So if there are parts that came with the car and should not be installed anymore, these would be noted with a particular code.
Although I have not been trained in EPC, I have some experience with a number of other parts softwares and such.
So I would see in EPC that something was going on, even if I couldnt tell what and they would have to show both part numbers.
The problem is that sometimes parts guys cannot be bothered and instead of doing a model search in EPC, they do a VIN number search. The vin number search won't tell you what happened with earlier or later cars and then they conclude that mysterious things happened.
