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!
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??
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.
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
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!
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.
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!
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?
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?
Thanks for this video! May I ask you the size of the male and female Torx for the headbolts, please? Looks like Torx 60 female for the old bolt, but don't know for the male for the new ones. :-)
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.
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 -
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.
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
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.
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
@@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.
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
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
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
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
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 ?
Not only is there a specific sequence from center to the outside of the head, the tightening of the individual bolts is a multi-step process, starting with a 10Nm torque, then a 50Nm torque, the three successive 90 degree turns, all using the tightening sequence. The valve covers also have a tightening sequence.

I don’t own a CL and will never do this kind of work but I watched this video bc I enjoyed watching your skill. Impressive.
Thanks this is one of the best explanatory videos on these issues that I have watched.
Great video!
Looking forward to the C63 /SL conversion and the new project!

WE MISS YOU! Love it when you upload
Great video, could you do a video on rear main seal, like symptoms, diagnosis and how to repair it like this video
This task seemed daunting from other videos I've watched, but you've made it look so simple.

Love the channel. Long time subscriber here.
Fantastic video mate, tgat is the way make those. I just loved
You are a hero. Thank you for posting
Excited for the c63 project !!!
Buy some fender covers or us old towels. Having oil drips on your customer's car looks like crap.
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
Great call on the aftermarket warranty brother, that’s the ticket.
Can you share which insurance company?
You my friend are a very skilled technician.

Hi @xf motorsports! Great video, a lot of knowledge here. Could you tell us please what is the torque required for the camshaft adjusters bolts?
Can you please make a video on replacing M157 waterpump and coolant lines since its so common
Nice video. Nice job on the repair.
Great video well explained
Thank you 😊

Great video. What is torque on new head bolts
We are gonna need a sample of that next project fairly soon
About to do headbolts on CLS63 but the head gaskets are already leaking so off come the heads...FUN TIMES 😂
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!
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
great stuff, as always!...can't wait to see the secret project. i'm guessing an airplane???
I hope the new project is a single seater, can't wait to find out!
Excellent video! Just subscribed.
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?
very informative video. Lucky the cam bolts were oke considering the mileage
Great video man!!!
Incredible! Where in Canada are you from?
awesome vid helped me alot
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?
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
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 😅
What type of filler rod material did you use? Just regular steel? or some sort of alloy? thank you
Thanks for this video! May I ask you the size of the male and female Torx for the headbolts, please? Looks like Torx 60 female for the old bolt, but don't know for the male for the new ones. :-)

Where are you located. I would bring my car to your shop when there's a problem. What a genius mechanic! AMG expert!
So was the MAXIMUM 20v 195nm impact wrench enough to loosen those 20 bolts ? :)
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 -
What do you plan to do with the shell of the c63?
How much does both these repairs cost ? I really want to do it to my 2010 c63
What torgue spec did you use to tighten cam adjusters plate
this is fun to learn and play with metals
Wow amazing video!
Thanks for a great video. What was the mileage on this M156 engine?
112980km
amazing job !

Can you the cams on the biturbo 550s? I got a cls550 that has worn adjusters, always clunks at a cold start up.
I wish you were here in US I need same work done on my CL63
Which years of 63 cars did they switch from the m156 to the m157.
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
Is the secret project AWD? That's the only way I can imagine it being significantly faster than the race car.
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.
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
Don't forget the lifter buckets.. lol that is the main problem.. intakeside doesn't get enough oil
Masterfull work
Can you give example of noise caused by bad camshaft adjuster.
What's the torque specs on the head bolts and the covers ?
How about a manual swap for the ML ?
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.
@@SeishukuS12 Sintered stuff is normally used where it is too hard/expensive to machine.

Thought this was an old engine , should be well out of warranty with a dealer .
what's flipping the pin? I heard that's another way to fix the adjusters
this guy is not a general mechanic he is definitely an engineer !
what engine damage would occur beside annoying clicking sound from the bad cam adjuster pin if not fixed ?
That plate is severely damaged, how many kilometers it had ? Is there any range to change them as preventative measure?
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
you should weld the worn whole shut and mill new whole on the other side
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
Hi. M156 E63. What part of the engine is the oil temperature sensor in? Can you help with this?
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.
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
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
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.
On the M156 if you dont fix the noisy cam adjusters would it cause any other damage or would you just have to live with the rattle on startup?
This is a good question cause that's what I wanna know cause someone is telling it leads to a big job.
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 ?
Hello
How much newton for the 5 screws on the adjuster ?
Thanks
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?
How much did this job cost parts / labor if I may ask ..?
is there a specific sequence for bolt replacement? Or I can start from anywhere? Like clockwise?)
Not only is there a specific sequence from center to the outside of the head, the tightening of the individual bolts is a multi-step process, starting with a 10Nm torque, then a 50Nm torque, the three successive 90 degree turns, all using the tightening sequence. The valve covers also have a tightening sequence.
Is it possible to repair the cam shaft? Or is it better to replace? And where can I order the camshaft and lifters?
You gotta change those cams brother, they’re toast.
@@cesartoledo5621thanks,
i have a Mercedes 500ge but can't the right camshaft.
I can't order it anymore from the dealer.
Did you replace the head gasket lmao? Or just the bolts 🤔😐
Twice as fast as the E55 ASL ? A Bonneville landspeed car maybe ?
