300,000Km+ Mercedes M104.980 - I Remove The Cylinder Head

- I can't beleive how good this engine is inside when the car body is such a piece of crap. Clearly the previous owners looked after maintenence religiously before the car body was left to deteriorate outside.

That's amazing! That you can still see the honing marks on the cylinder walls after that many miles. Mercedes has proven that they can engineer a very durable engine.
I looked back at the service records that came with this red car and found that the head was removed at 157,000km to fix oil leaking from the gasket. It’s never had any welding or repair work done, only cleaned and reinstalled. The engines outstanding internal condition can be attributed to the no nonsense no expense spared maintenance it experienced during the ww2 fighter pilots ownership for 10 of its years. After that maintenance and care with subsequent owners is undocumented and quite likely questionable at best. Not only is this guy a hero for his services but he’s also a hero for how well preserved the inside of this engine is, even though the owners after him didn’t take such good care.
I would like to know where did you get the printable menu from
It must be from the front U seal?
Amazing cilinder walls!
thumbs up for the gloves
anyone who puts a 2JZ or an RB anything in a merc has never done this or simply doesn't understand engines
the m104 is pretty much a mercedes version of the 2jz
actually anyone who understands about engines will put a 2jz in a merc. 2jz block is superior in all ways compared to m104.
even without taking any measurements you can see the weakness of m104 by just looking how thin the block is between the bores, that will crack in any serious hp applications.
@@Vratz99 faxx! Planning m104 swap myself right now but the m104 is pretty bad compared to a 2jz. Nothing inside is forged, the rods are thin ,the crank is weak all of this doesnt apply to a 2j. Still an awesome engine tho
Vratz pumpish has proven that the m104 block are tough to crack
@@Vratz99 I guess you've never been to the turbobandits website.
Greetings from Houston! I just found your channel after I acquired a 95 W124 E320 Wagon. While I'm not planning on rebuilding the engine, I do plan on rebuilding the power steering pump and quite possibly replacing the cylinder head. I've got a young channel dedicated to repairing/restoring old cars like these. I also have a Porsche 911/996 that I'm fully restoring. Be sure to check it out. Cheers!
That leak at the timing chain cover and head gasket corner so expected
oil change is the main key to a long engine live.. and the long Intervalls of modern cars is one reason why today´s engines struggle more and more to last that Long...
It´s up to the owner.. you don´t have to do 30.000km Intervalls just because the manufacturer asks for it
I am so pleased to own this engine in my '99 S320 - Maintenance records to the first owner - @ 225K Km - and I wish that I had the ability, like you, to look at the inside but I suspect that it is in pristine condition. Thanks for posting this! Did you change the t-belt or anything else?
I've not done anything yet, other than pull it apart. I've a spare room of new parts waiting for the red cars restoration, but I'm not starting the m104 engine rebuild till we have finished with the 6.3 engine or at least finished it enough so my friend can take it over by himself. It wont be much longer, hopefully.
How is your S320 going? I recently picked up a 93 model
Wow looks pretty decent with no corrosion after 300,000+ km of use
I observe all safety precautions, such as wearing my Japanese safety boots (Aussie slang)
was doing the head gasket on my musso (which is running the same merc engine) on the weekend and was wearing the same safety footwear lol
280k and still had visible cross hatching in the bore. no need to measure if the cross hatching hasn't worn off.
@@rjredd Do the heads generally need to be shaved on these when replacing the gasket?
@@19jacobob93 I`m no mechanic but as a general rule of thumb all alloy head such as this one need to be shaved, also get it crack and pressure tested. you dont want to do all of that work and not have it seal or have other issues.
That thing aint even broken in yet
I'm about to restore my M104.980 Evo 1 as well. As a Mercedes apprentice, I am able to get all the repair manuals and tools required however, there's one question I'd really like to ask... How do I replace the timing chain whilst still having the crankshaft's TDC and camshafts' TDC remain aligned? Do I just mark it with a sharpie or is there a special tool or something? How would/did you do it?
All we did in our work training so far was disassemble and re-assemble factory engines that were not even more than 3 years old, we did not replace any parts on those engines.
Its explained in the manual, when replacing the timing chain. I will have to have the cams in their designated positions (holes with pins in them) and the engine in tdc when I fit the head. The heads been refurbished so the cams are in random positions currently. I had to do this on my blue black cars engine too. It is critical that the intake cam position be understood correctly because if timed incorrectly it will result in bent valves. I would advise having a read of the cam timing adjustment process when replacing timing chain. I did not have the cams move on their own once the engine was in TDC and the cams in their correct position, though it was 6 years ago now I can barely remember. I will be installing the head on my rebuilt engine soon enough and will have to read up myself. I also have to crimp the new chain, I have the tool. I still have not purchased one of the timing chain guides or I would have installed the head already. (I also need the 3.2 gasket too since it is no longer 3 litres)
Hi nice work i got a c36 amg.
where did you get the service manual documents?
Hope you'll gone answer to me
a putaquepariu i have the electronic parts catalog and workshop information system installed on my computer. Most documents are in there for cars in the 90’s and newer.
hello I need the document in this video removing and installation manual. Can you help me?
Wow, incredible!! Do you know what motor oil was used to maintain such good condition? I currently drive a S320 with a M104 in it!
Timothy Lam the owner that did the most kilometres was a fighter pilot in ww2 and spent rest of life as an airforce doctor. He serviced the car on time or early every time. The oil type on the receipts is nothing special, what is important is doing it regularly with a new filter. Changing cheap oil often is better in my opinion than leaving expensive oil in too long. Not that i use cheap oil i only use full synthetic.
@@MMWA-DAVE yeesss !!!!!! 😃😃😃😃
agreed
For M104 - MB Approved 229.1, 229.3 or 229.5 oil. In terms of viscosity - 0 up to 10 for the winter index and 40 up to 50 for the summer index, depending on the condition of the engine.
300 is not so much for this engine. proper maintenance and you can show us something about 600-900)
One quick question... can you put m104 head on m103 bottom end ? and is it bolt on or you need to do mods?
pretty sure it would be possible, crank and rods etc are all m103 part numbers - you would have to change the pistons though. m104 pistons have the cut outs in the top for the 4 valves, m104 engines are also higher compression than m103 - it may work as is with the m103 pistons but wouldnt be optimal.
MMWA What about the lines inside the head and block for the coolant and oil, do they match ? Thank you a lot for the info :)
@@driftinrust Interesting thought.. when i swap the headgasket on my turbo m104.980 mercedes 190 trackcar. I will compare it to the turbo m103 i´m building for my 190 stancecar/showcar now. i have 2x m103 blocks laying around. i´m currently building a stroker from one of the m103´s. with a crankshaft from om603 and honda H22a rods and original pistons. if i´m right i´ll end up on a 3.4l m103 with turbo on the stancecar/showcar
The head gaskets probably different as I think there coolant slots between each cylinder on the m104 and none on an m103
Confirmed. M103 3.0l and m104.980 are exactly alike. They got the exact same partsnumber and even the crank from 3.0l is the same. All you need to do is use a m104 headgasket to fit a m104 top on a m103 block 😊 and ofc use m104 pistons. In my case i'm running custom forged billet h-conrods and pistons to lower compression for big turbo boost 😇🤩
Hi !
Can u give me the document or just the page where is mentionned torque tightening for the head cylinder ?
Thanks for your answer
the sheet comes with the new elring headgasket. The figures are different from 3 litre to 3.2 m104
Ich glaube du verstehst Deutsch:
Das Problem sind die verkockten Ölabstreifer. Das wichtigste, das Ringpaket zu erneuern. Über die Verkockung verbraucht der Motor Öl.
Ich habe gerade einen 3.2-24V fertig (3.2 HFM Block mit 3.0-24 KE Kopf). Auch bei beiden Motoren waren die Ölrückführung von den Ölabstreifern nicht mehr gewährleistet.
Ansonsten sind 300TKM kein Laufleistung.
I dont understand German, but I run your comment through google translate. Thanks for the advice I will certainly check this on the weekend. I am pulling apart the bottom end on Sunday. My bores all look good and all measure to 88.5mm all over. I was thinking to install the 3.2 crank, rods and new pistons from a donor w140 300SE engine if this engine needed oversized pistons as they are no longer available. Is this a common modification?
Welche Ölviskosität empfehlt ihr?
Ich halte mich ja an 5w30 Vollsynth was oftmals als zu modern bezeichnet wird bzgl Additive
I have a Mercedes w124 2.8 or 3.2, they opened the engine at a mileage above 420,000 thousand and its condition is much better before that, no one climbed into the engine and opened it.
So I’m doing a head gasket on the same engine. Question is, if I take off the head just as you did in this video, without disturbing the cams, I can just put it back on and the timing will be ok, right? Thx.
you should follow the service manual. You can get them for free online. I would not be haphazardly doing this job and risking bent valves.
+1. .. Thanks
DAMN!!! crosshatch engine internals porn!!! A++ luving it!
Where can i find that book about m104 repair. im brazilian and here dont have much information about MB and i bought one i i want to start maintence on her.
Victor Dutra m104 factory orignal manuals are very hard to come by. The good news is most of the manuals for 90’s onwards cars were archived by MB into PDF. They are available in the workshop information system which is a companion to the EPC. (Parts catalog) being a bit computer savvy is required to set it up but last time i checked some people were still selling the (questionable legality) epc’s on a virtual machine image you just run on a recent, capable computer. My virtual machines are all running on macs so thats not a limitation either. The topic is too big to discuss here but there should be lots of information online as to how to get your hands on a working setup. Alternatively there was also a dvd set of manuals for the 124 from MB USA but in their market the m104.980 was only used in the 1990-92 300CE so takes some changing between models to find everything you need plus that software only runs on older computer setups now. I think the PDF’s from it are online too on a 124 specific forum. I can’t remember which.
@@LopLemmonvery nice! Awesome DIY.
I have M104 E280, bought used. Could you pls show me some photos of your relay box, how the relays are connected.
I took out the relays the other day and i have forgotten where to place the green relay, mixed up with the blue one. I searched online but couod not find any answers for this specific model.
Thank you.
My email is chrisgooi@yahoo.com
chris gooi , Thank you for your comment. Unfortunately I don’t have the photo of my relay box, but following url may help you. mbw124.com/AC2/wp93-accExchange2.htm
Somebody strangling a goat in the background.....?......😆😆😆
I think the noise you are talking about is our local raven / crow. (not a bird expert) They are very very noisy birds and like to hang out in places where the noise is not wanted. It’s not unusual to have them congregating in large numbers at high schools particularly around the time of final exams etc. All part of the west australian experience. they do make a AAAARGHH AAAAAARGHHH AAAAAARGHH. noise
If i'm not mistaken, the engine block are the same with m103? It is the 3.0L m104 right?
What wears on the top end of this motor besides the cams?
usual things like valve guides and valves, the hydraulic buckets also become leaky or gummed up and cause ticking noises. I leave the complete cylinder head to the experts to refurbish, it’s not something I touch other than remove and reinstalling.
@@MMWA-DAVE so if I know someone that has a rebuilt 104.99x head with only 2000 miles on it (car was totalled right after), would it be worth all the effort to remove his head off his totalled car for my future use? Or should I just rebuild my own head when the time comes? I have 150k miles on my car.
@@nehuge is yours the same type as the one that’s available? If you have an m104.980 like me theres a lot of work involved around making it suitable if its not from the same.
@@MMWA-DAVE its same. 104.992 and same year and model and everyting
@@nehuge then definitely- save the whole engine and hang on to it. If you do take whole engine make sure the coolant is completely drained for long term storage and seal off all openings.
Can you give us this digram for engine
Mercedes intended that timing chain to last the life of the car, so be careful with it. I called Mercedes today and they don't even have any in Germany. I had my car in for a head gasket and the shop botched the chain tensioner reinstall, which resulted in my chain breaking first road trip. They claim the chain "just broke", so they're not honoring their service warranty. Opposite to your car, my car (a 1992 300SL (-24)) is completely mint with the exception of what's now under the hood. Total disaster.
Chosen Idea this will give me nightmares. I do hVe a new iwis chain for the pump and timing - they require the special tool to crimp the ends together which i do have. I’ve not done this before and will read up on the manual befofe proceeding. I will be thoroughly checking that crimp before closing up the engine
What was the reason for the head gasket swap? If it was because of the famous oil leak that can be fixed by simply re-torquing the head bolts in most cases.
It was leaking a bit on my 92 S320, retorqued them back to spec and it has stopped completely.
Not in most cases, but sometimes. I've owned a few m104 cars. Lucky you. Mine wasn't leaking, it was gushing.
@@chosenideahandle Yeah I believe that's the point beyond a simple retorque then. Yes I was lucky to catch mine early...
Probably could have taken that further if you had good evidence of what was botched
