Your knowledge of these complicated vehicles is so impressive! Your passion really shows!
Thank you. The V12’s I have a big soft spot for
@@DCMotorWerkswho wouldn’t!
I just discovered your RUclips Channel. You’re making some very informative videos. Thanks for sharing your knowledge and experience with us. Keep up the good work. I’m now a subscriber😊
Thank you so much!
Best video thanks so much for the information
Our pleasure!
I have a 2007 s65, just did engine and tranny mounts but I couldn’t tell anything was wrong other than the fact a vacuum hose kept coming off and tripping a check engine light, and my entire front end other than struts was shot, car rode so good and was so quiet I couldn’t tell until it went on the lift, ride quality is insane now
Happens gradually so a lot of people don’t notice!
Wow I hope the guy has Deep Pockets that owns the thing..
Would you suggest buying a regular V12 before the turbos come out because I have two of them
Fantastic work guys. I'm amazed that you don't have more subscribers. Hi from the UK.
Thanks! Us too 😅. All in good time hopefully!
thank you, im looking at an 09 SL now. needs coils i think, low miles. just looking for a nice weekend summer cruiser. Any preventative maintenance i should do while its on the lift this wnter?
Flush the ABC fluid. Give everything a good lookover. Check date codes on the coils.
Love how informative your content is. Is this the engine with the O ring that needs the heads removed to replace it? Ever worth that as a while your engine is out? Guessing not but had to ask.
I did make mention of that one in the video. This is that engine however it is so uncommon we do not worry about tearing the engine down to replace it unless it has actually failed.
Carl Rupp's Boost Box and coil packs go a long way toward maximizing consistent performance and efficiency.
He’s a great fella!
I am going to do some research on this "Carl Rupp" that you speak of.... Being that "he's a great fella"...... Thank you!!
I actually see a "Clark Rupp" addressing this topic.
If I ever own a v12 M275... guess who gets the luxury of fixing it! Congrats!
We’d be glad to!
I always thought the "AMG" V12 had the M279 engine & the regular SL, CL & S class V12 had the M275 engine.
Definitely appreciate your knowledge...
& I'm definitely gonna look into the W.C. reference you've made.... I've gotta replace one of my coil packs at the moment, and I've replaced my voltage transformer. THANKS AGAIN THOU!!
M279 is the revision of the M275 launched in the R231 SL and all V12 models post MY2014. Up until then they are all the M275 unless its the Maybach (original maybach) have the M285. Pagani uses the M158 Version. All iterations of the same engine though

Thank you!!!....I Wish I were closer to your area to do business with you because I appreciate that you seem to have knowledge of the V12.
A lot of auto "specialists" appear to be afraid one way or another....
I deal with a strictly Mercedes shop & even they are afraid of the V12 as well as the ABC system so I'm forced to deal with the dealership in some cases. I would luv to be involved with someone that's truly knowledgeable in this category..... Anyway THANKS, & good day to you!!!

24 is a lot of plugs to spin out!
badass engine requires badass maintenance.
Exotic cars come with exotic prices!
About how much does an engine out service cost for this? Thinking about getting it done for my S65 soon. W221 chassis.
The engine out w/ new mounts is about $5k. Then you get into all the while you're in there stuff. Adds a few thousand usually.
Any common problems on the m120? Have you done any videos on those? I read somewhere that oil leaks were a common issue.
Good idea. Next time we have one in we will do a video on their common faults. A few oil leaks, the upper timing covers are a bit of a chore
@@DCMotorWerks great. I’m excited to see when you get one and break it down
Hi how much cost all the parts whitout labor ? The mounts the gaskets seals and vacuum lines?
Really depends on how far you want to take it
For the O-Ring, is the replacement better, more resilient, and improved than the OEM to end that problem once and for all?
I don’t have an answer for that unfortunately. Will be another 15 years to tell. Uncommon anyhow. Think it’s more based on oil quality and oil change intervals
@@DCMotorWerks Indeed, point taken. Thanks. Do you accept shipments of the engine to repair? Say if I end up owning a M275 that needs a full restoration? Thanks.
Curious to know the mileage on the engine please.
55,000
Nice video! But this is insanity. This is unaffordable for the average person. I can only imagine the total bill for parts and labour with a Mercedes dealer. I bet you can buy a brandnew (budget) car for that kind of money.
Thanks for the effort and length of this video, I wish you're able to make more of these videos if time allows you to do so.....
Thank you. Yes they can definitely wreck a budget. However, they really are a lot of car for the money as much as they have depreciated but unfortunately the service costs don’t depreciate.
Yep i would rather a corvette anyday! I'm sure they designed it to be a pita to service on purpose. Im sure it drives amazing though. I have an S55 myself, and researched the v12 cars years ago. Way more expensive and harder to work on, i would choose sl55 over v12 anyday.
Nothing about an SL65 is for an average person. These were Mercedes most powerful engines. For those insisting on V12's, Mercedes has the most experience as the highest volume V12 manufacturer.
Anyone ever try and remove the engine from the top?
Not that I’m aware of. It’s not hard to get it out the bottom
I’ve got the 4 post lift so getting it high enough from the ground is the challenge
Seems pretty hard to take the motor out from the top since you can't even get to the motor mounts since this is what he's taking it out for
Crankshaft Position Sensor
They pop up sometimes. much more common on 112/113 engines.
@@DCMotorWerks Why is that? They use the same part.
Can this engine work in w210 chassis
I’ve heard of it being done
Yes Brabus have the e65 w210 whit v12 dont know or its this M275 engine it should be after built because this engine is in production since 2003
