Keeping oil level close to the max is the key on m156 to ensure timely oiling. For those looking for a detailed m156 head bolt DIY, I have one on my channel.
That’s true. I also drive my car in M mode or limit the gears so that the RPMs are always about 2500 to ensure enough oil pressure to push it to the top if the engine.
Just curious ..nowadays how much does 156 head bolts replacements will cost @ an Indy shop ? How much do you charge ? I’m actually thinking about doing it myself but I have no tools. 🤣
@@enzoi9569 if you do it yourself (again, I have a DIY video on my channel) it costs about $350. If you pay someone it’s 10 hour job. So ask them how much they charge per hour.
Good and informative video. For us home mechanics, however, who do not have access to Mercedes official service manuals, we would love to see torque specs and a list of the special tools you use to keep in place the cams before removing them.
First time I've seen the plates fixed that way and I must say I love it! I hate how Mercedes and other companies charge extremely over exuberant prices for these plates that I'm sure are made pennies on the dollars. Thanks so much for showing an easy way to fix this issue.
as a MB tech i have always wondered what failed inside of these, of course they are cores so i could never take them apart and look. I also do these a ton on the M271 EVO, good to know!
the head bolts on my r30 m156 went bad a 62k miles. I had aftermarket insurance and the covered everything which included head bolts the hydraulic pump for the suspension and both front struts. afterward the m156 is a dream
Thank you for these great videos. I have a 2006 C280 with a 272 engine that has this problem on the left side (driver) cylinder head. The previous owner neglected they car by NOT changing the oil frequently. These multi cam/ flex cam engines need clean oil and correct quantity of oil or they fail in many ways.
It looks like a tricky job, replacing the head bolts without disturbing the head gasket , was it difficult to clean out the oil from the block holes to prevent hydraulic fracturing?
@@SeishukuS12 Sintered stuff is normally used where it is too hard/expensive to machine. It would probably be way cheaper to machine a simple part like this, especially if it is soft metal.
@@coast2coast00 normally, yeah, but it can also lend to mass production as well... In high numbers it would likely be cheaper for a sintered part. The surface and edge finish kind of look like a sintered part as well, though that could also be just a tumble stone polish.
I am genuinely curious about how the underside if the head bolts corrode, what are they coming into contact with that can make them corrode? Also hopefully the person making the replacement plates for the cam adjuster is making them out of a more durable metal, if so they should be the go to replacement anytime someone works in the cams.
Those bolts look fine. Just some light surface rust. At that rate of corrosion it looks like it would do the same mileage again without causing a problem. But since the covers were coming off anyway it makes sense to do it now.
this is an excellent video. i loved the explanation of etorx vs torx on the head bolts. you're very well spoken and describe things very well. i am curious, now that you have fixes, do you sell rebuilt cam adjusters??
Yeah, you can almost replace the cam adjusters (Nockenwellenversteller is a much more beautiful word) when you change the oil filter in the M156. 500HP for a naturally aspirated crossplane V8 was probably too much to ask for.
i am in the market for a S 63 or a CL 63 07-10, which years have the least issues, or is it the same , and how many miles is too much to stay away from!!. Thanks
I have a 2008 s63 with original headbolts. The car has 120k miles. Should i change the Headbolts? Or it shouldnt be a problem at this mileage since its already 120k?
Thank you for you content. I like Benz cars but their cost saving measures are shameful. Good to see a channel focusing on making trash cars reliable. I want to be a machinist so I hope I can replicate parts someday as well.
Dude your videos are awesome! Help me so much with my c63 head bolt job. Question I have in case you see this, did you put RTV on the new head bolts? Any specific type needed for that? Also, with the cam adjusters, how do you get them back into their correct position if after you take them out, they are slightly misaligned? This happened on my c63 because the hole in the gears isn’t threaded so all I was able to do is stick a 5mm bolt in there to hold them in place however upon removal, they are about 1/8” misaligned. My buddy working on the car with me says they can be payed back into place with a flat head. Just curious if you have any tips or tricks on how to do that without risking damage of the cam adjuster. Thanks!
great video thanks dont your think it would have been better to change the head gasket as well tasos Moschatos recommends not changing the head bolt without changing the head gasket as it disrupted even if you do each bolt one by one thank you
This summer i will be doing my cam adjusters. Since the camshafts will be off its quite obvious its no or never to also do headbolts. BUT, my m156 has 166,000miles. No record of anyone doing them. Vin is in the affected range. My main question is when you reinstall the camshafts does the cam holder tool put them back in the correct position as when you removed them?
Hey brother be careful when you remove those head bolts. She got a few miles on her and then damn bolts get so corroded they snap. I seen it it’s a nightmare, god bless and good luck bro.
You can easily drive with night vision watching a screen the only bad part is 0 depth perception. I drove with night vision while serving in Afghanistan one of the lead vehicle in one of our convoys drove into a deep hole lol I was a mechanic with the tow truck so I had to pull him out not bad just deep enough to get stuck and damage the rollers used to protect against IEDs.
My s class has the same night vision and you are correct, if you turn when you think you should from screen image you will turn to soon , bus drivers might be ok 🤣, also thanks for serving 👍🏻
Hey - this video is great - I have two 500SEL's - I am wondering if these engines can be retrofitted into them - making them the beast - Have you ever seen anyone doing that? I am in the USA - you in Canada, it might be difficult -
Do you have to flush the coolant before you start taking the old headbolds out.!?! I saw other videos where the coolant was flush completely before taking the headbolds
Can you let me know how much to tighten head bolts. And another question on my right engine head I have oil leak so I already have bolts that are not good. Can i replace only bolts and not disturb head gasket. Please advise thanks
Great video! What was the shop called that did the welding repairs on the cam adjusters? I'm in Vancouver and have this problem so I would like to look them up!
hey man, what part of canada are you from? i have a sl430 MY2000 in my garage t home, and having a few issues with it starting i was wondering if i could some how make contact with ya and we can talk, thanks kevin
Yes but the metal is soft and will wear out in another 50-70k miles. The metal in the welding rod is measurably harder and should therefore (in theory) be a big boost to the lifespan of the adjuster.
@@FILTHY-YOGURT That is a good point, but I believe any increase of wear on the pin would be negligible. The spring applying pressure to the pin is fairly weak and it's a polished surface against a polished surface. The pin is also rounded and less likely to "erode" on the tail edge that drops in hole. These guys are smart and came up with a simple, efficient, and cost effective way to extend the lifespan of a poorly designed component. 👍Just my opinion as an experienced MB tech.
I found a c63 Amg 2009 guy said they changed the head bolts an after that it started to misfire 1-3 cylinder it has 155k miles his asking 8k what could be the problem
Great video! How far from Michigan? I have an 09 SL63. Head bolts already done but worrying about camshaft & valve buckets. Do you still fix those issues?
Hello I got 2010 with m156 motor and 130 k miles on it , it is old head bolts should I replace them or just leave it since nothing shows any problems now ?
How much does this service run. My c63 is at the same mileage. I'm located close to your shop and would love for you to have it in to make sure she's in tip top shape

Great call on the aftermarket warranty brother, that’s the ticket.
Can you share which insurance company?
Great video!
Looking forward to the C63 /SL conversion and the new project!
Buy some fender covers or us old towels. Having oil drips on your customer's car looks like crap.
Thank you for making these mercedes videos! Really good information for 63amg's. Greetings from Finland!
Thanks this is one of the best explanatory videos on these issues that I have watched.
This task seemed daunting from other videos I've watched, but you've made it look so simple.
Great video.The zoom + flash is awesome to see the little details youre explaining.
WE MISS YOU! Love it when you upload
About to do headbolts on CLS63 but the head gaskets are already leaking so off come the heads...FUN TIMES 😂
You deserve way more view than what you have now. Keep up the great work.
Great video, could you do a video on rear main seal, like symptoms, diagnosis and how to repair it like this video
You are a hero. Thank you for posting
very informative video. Lucky the cam bolts were oke considering the mileage
I am a BMW guy, but I really admire your great work! God Bless you!

We are gonna need a sample of that next project fairly soon
Excited for the c63 project !!!

Actually tasos Moschatos would not change the head bolt without changing the head gasket as it disrupted even if you do each bolt one by one
wow. I didn't realize how soft those plates were. i have this going on with my M156 and fighting with the dealer to get them to fix it under warranty.
They look like they're probably made with a powdered metal process and didn't get proper heat treating.

Thought this was an old engine , should be well out of warranty with a dealer .
Fantastic video mate, tgat is the way make those. I just loved
Don't forget the lifter buckets.. lol that is the main problem.. intakeside doesn't get enough oil
what engine damage would occur beside annoying clicking sound from the bad cam adjuster pin if not fixed ?

Also hopefully the person making the replacement plates for the cam adjuster is making them out of a more durable metal, if so they should be the go to replacement anytime someone works in the cams.
I wish you were here in US I need same work done on my CL63
Is the secret project AWD? That's the only way I can imagine it being significantly faster than the race car.
The m156 is beast for power gains. From a reliability standpoint id much rather take the m113 na.
This. M156 for power and sound only, M113 for reliability and durability.
I got 180000 miles on my beautiful 2000 w163 ml55 with the m113NA , she runs like brand new. No one sells aftermarket upgrades for her though.
Those bolts look fine. Just some light surface rust. At that rate of corrosion it looks like it would do the same mileage again without causing a problem. But since the covers were coming off anyway it makes sense to do it now.

Great video. What is torque on new head bolts
I Love me my big body coupes and this is defs a dream car.
The one with the M156 is better, drove one for a while my cousin had one but it was totaled.
How much does both these repairs cost ? I really want to do it to my 2010 c63
Where is the finished e55 manual???
Probably waiting on the ECU
Be great to see a complete kit, clutch pedal and reservoir would be my only concern as I’d prefer it to look more factory.
I hope the new project is a single seater, can't wait to find out!
Great video 👍 Do you have a link for seller of cam plates, Tasos would put an order in for sure.
I guess Tasos knows where to get the parts 😅
Love the channel. Long time subscriber here.
this guy is not a general mechanic he is definitely an engineer !
What do you plan to do with the shell of the c63?
this is fun to learn and play with metals
what's flipping the pin? I heard that's another way to fix the adjusters
Did you replace the camshaft adjuster bolts and washer? I’ve heard there one time use but also heard that it’s fine to reuse them
What's the torque specs on the head bolts and the covers ?
i am in the market for a S 63 or a CL 63 07-10, which years have the least issues, or is it the same , and how many miles is too much to stay away from!!. Thanks
What type of filler rod material did you use? Just regular steel? or some sort of alloy? thank you
Thank you for your wisdom.
Would be nice explaining plate @15:36.
Where are you located. I would bring my car to your shop when there's a problem. What a genius mechanic! AMG expert!
I have a 2008 s63 with original headbolts. The car has 120k miles. Should i change the Headbolts?
Or it shouldnt be a problem at this mileage since its already 120k?
So was the MAXIMUM 20v 195nm impact wrench enough to loosen those 20 bolts ? :)
Hi what is the cost for this job to be done?
Too bad you were not in Texas! My M276 needs timing adjusters lol!
can you give me pointers on how to find the one lifter that makes noise on a M276 engine?
Great video well explained
Thank you 😊
What torgue spec did you use to tighten cam adjusters plate
One bolt at a time? Hopefully none of them snap off when removing them 🙈
So if you change the bolts one by one it will not damage the engine headgasket?
Those bolts are torque to yield, they gotta go down and hit the bottom for real, if not it’s over.
Can you please make a video on replacing M157 waterpump and coolant lines since its so common
Nice video. Nice job on the repair.
Awesome! Personally I would love to put 6.2 LS with a manual box in the C63 shell. Curious what you will come up with
Thank you for you content. I like Benz cars but their cost saving measures are shameful.

Whats the 5.5 twin turbo engine like in terms of reliability?
Did you replace the head gasket lmao? Or just the bolts 🤔😐

You gotta change those cams brother, they’re toast.
@@cesartoledo5621thanks,
i have a Mercedes 500ge but can't the right camshaft.

you should weld the worn whole shut and mill new whole on the other side
Do you have to flush the coolant before you start taking the old headbolds out.!?! I saw other videos where the coolant was flush completely before taking the headbolds
That plate is severely damaged, how many kilometers it had ? Is there any range to change them as preventative measure?
Where is your located? Thanks
