For people that haven't seen the previous videos, keep in mind this is a time attack car. I've been using it on the track for the past two years so its been through a lot more stress than most other E55's My point is that if it happened on this car it might happen on other E55's later down the road, and without an oil pressure sensor or switch there's no way to tell when something like this happens. Its something that could have been easily prevented had I known in time, so Its worth pointing out to others so they don't fall for the same thing.
Wait....There isn't an oil pressure sensor on that motor? My Kawasaki lawn mower engines and my pressure washer have oil pressure switches that shut down the engine if pressure is low. WTF would an engine like this not have at least an idiot light???
The space shuttle worked as designed as did the SRBs. They were operated way out of thermal design spec due to some greedy bastards at NASA. I suspect infrequent oil changes in the engine's past had some effect on the longevity of this o-ring.
Wow that is a shocking design fail from Mercedes! That O-ring was something they could have prevented and no oil pressure sensor is just a big design fail in my opinion. Keep up the good work man 👍
I believe this design only came in the E55's and newer cars that came after 03. The S class W210 and CL W215 had a much better oil pump design. The collector was a part of the pump rather than separately being mounted.
webnothing That's why Europe is full of Mercedes cars with 500,000 to 1,000,000 km's on the clock running like brand new? I don't think I sat in a Mercedes taxi in my life that had less than 500,000 km's on it. I love how tards always like to take one bad example and then shit all over the whole brand, while ignoring millions of examples that prove that the opposite of their belief is true.
I am impressed. I like how you laid everything of the broken down engine out in geographical arrangement. This a very informative video Thank You for sharing.
My pocket was saved a couple times when I lost oil pressure and obviously stopped the car straight way... No having an oil pressure sensor seems like a really crap ideia from Mercedes ... 😳
Wow! Awesome forensic analysis on why your engine blew. I see this with F1 where they inspect their engines after every race to analyze wear and tear. You're very knowledgeable and highly skilled. It shows. Thanks for sharing these issues with us. So glad you were able to get your hands on a replacement engine. Now I know why they were rated the best in the world for durability and reliability over many years. Looking forward to more amazing videos like this. Keep up the great work with your channel!
As an M6 owner and former AMG owner this pains me to see. At the same time I am grateful for your efforts in showing the engine and the issue and I hope no one else suffers this because it’s a gamble putting in a new used engine.
That sucks, a little o ring caused the destruction of your entire engine. Also I was really surprised when you said there’s no oil pressure sensor. That’s just plain stupid
This is the problem with tracking old cars, parts are worn out and things fail under the stress conditions of the track that won't fail in normal city driving.
It makes sense. Apparently the engine was destroyed before it actually blew up, because of massive wear. The oil pressure is definitely a sensor you would wand on any engine. Even the cheapest engine have it. But instead, Mercedes is preoccupied more about comfort, like fitting a boot light failure sensor. Nice job. Keep it up!
A lot of confidence the designers put on that tiny o'ring. This is simply a design flaw. They could have easily implemented an auto shutdown system in case of low or no oil pressure together with an indicator and warning light. Excellent video, unfortunate occasion.
cant believe that these cars dont have an oil pressure sensor, very chep car I know has that. Of course if the pressure drops there is already damage done to the engine, but atleast the driver gets an idiot light and doesnt ruin EVERY part in the engine...
yeah I know. The oil system is the heart of the engine, at least have a warning light. I seriously believe ,and I do this to all my builds, the engine needs an engine cutoff based on the oil pressure. below pressure cut ignition and fuel. larger diesel motors like international do this.
Hi, if not all AMG engines at least the M113k, M156, M157 and M275 doesn't have oil pressure sensor, you found it with the hard way that you need to install an oil pressure gauge.

Interesting. My guess is that the o ring was cut during installation. It's also my guess the redundancy of the Benz design allowed the engine to survive during normal use even though the pump was cavitating. It's probably the competition use that pushed the conditions (high rpm / hp demand, hot / thin oil, g-forces further compromising oil pickup, and so on) beyond the rod bearing's ability to cope. #5 rod is the furthest rod from the pump supply, so this kind of goes along with the cut seal line of thought. Sorry for your troubles, btw.
SK8215 I’m sorry for your loss but thankful for the superb video you’ve made on it! Excellent explanation of what went wrong and what the culprit was. Thank you for the beautiful layout of (what is left of;-) the engine. It’s a shame Mercedes left out the oil pressure sensor but you’ve made maybe the best video in this category on it!

What a shame that a beautiful engine was wrecked because of a poor design flaw. Sure no low oil light comes on because it’s full but only staying in the pan doing nothing. All cars should have a oil pressure gauge. Makes a lot of sense. Thanks for a great video. 👏👏
Cars1999 probably wears gloves taking engines apart is easy but know what every part does and how it works may be hard for some people I just turned 18 and I took a corsair flatsix and Chevy v8 and a fzr1000 motorcycle engine head
It's how you care for them. I've been a mechanic for years and years. My hands are good. No gloves. Just some good grit cleaner, a nail brush, and cold water only.
Beautifully narrated video. Really. He went straight to the point with no drama, gave a ton of information, with no need to draw it out. Obviously he familiarized himself with his subject Before he picked up the camera. Most videos are an agony to watch because of unnecessary yammering, stammering, complete boredom, and some kind of need to be Cecil B. DeMille.. I own an M113k and will be installing a pressure gauge because of the information given on this well done video. Thanks..!
This might worry a few Mercedes owners on here. Might be an idea to ask Alex at LegitStreetCars guy on here, as her is was a Mercedes technician, and certainly knows his stuff.
You got me :( I've got one with 210000kms. I have spent allot of time on the e55 forums and have never heard of this. I'm in panic mode atm. A replacement engine in europe is 5000€.
learn proper german ,it´s called:"was ist das denn für eine scheisse" And no it´s not the g-force, if you would know something about the E 55 you would not state such theorys.
THANK YOU VERY MUCH FOR YOUR TIME AND THIS VIDEO,YOU SCARY ME,I HAVE E55 AMG W211...MONDAY I BUY NEW OIL PUMP...ME IN YOUR SITUACION SHAKING HANDS AND MY VOICE IS DIFFERENT....YOU ARE REALLY BRAVE...THANK YOU AGAIN...OH MAN I FEEL THE PAIN IN MY HEART.
I think that you should look at every single o'ring in the new engine not just this one and set a certain time to change all of these again as well. Definitely check out VRPSpeed.
Great video, thanks for sharing. After a careful and thorough analysis of your dismantled engine, I came to the conclusion that the real cause of the problem has to be that horrendous front spoiler!
Hi from Ireland and 2004 e55 owner great car loads of little bits to do but always puts a smile on my face !! Own 3 Imprezas sti from 94 to 97 and a 07 hatch bought the e55 as a daily driver even though it’s €1800 to tax for the year ! As Andretti said it’s the fastest taxi in the world !
the cl500 ZAS has an oil pressure sensor. it is really easy to retrofit one to any m113k. the spot is already there, just the sensor some gaskets and you got your peace of mind. I got pictures and part numbers if you want to go that route.
Anoop Patel sure. A1120150730, housing, mounted on the underside of the oil filter housing, needs m12x1.5 bolts. N000000001116, bolts as described. N007603012111, o ring. A1121840280, gasket. you may not be able to find it online but any dealership can get you these parts.
If you only fit one oil alert, use a buzzer. You don't have to be looking at the dash at the critical time to get the message. You can also add a pressure gauge and/or warning lamp in parallel. Belt AND suspenders. I used a seat belt buzzer from a crashed Honda.
I've seen a few oil starvation failures and it never fails to amaze me! The amount of damage an oil starvation causes is catastrophic! I had a BMW that had been overheated and dropped a valve retainer and the valve hit the piston and it was nothing on that!
A Few points your very good video brings back from memory. 1)For many years race car mechanics have installed a big red warning light to warn the driver of oil pressure failure. A gauge is a good idea,but belt and suspenders here. When driving,keep it simple,you will not be concentrating on gauges. 2)Various race car parts houses sell different designs of oil accumulator,some with the idea of a driver actuated ball valve for a last ditch way to supply oil for a few moments anyway. A good idea here. Try Summit Racing for a start. 3) I would be pissed. At the very least,contact Mercedes-Benz with a polite but very firm letter,paper not electronic. How dare they allow a point source of failure like this. Since it is not backed up with an appropriate idiot light,they are the idiots here. Any American lawyer worth his salt would rub his hands at a potential class action lawsuit here. You will not be the only individual affected here. I would be enraged,not philosophical. Racing does indeed improve the breed. 4) Fix this so that there is a better pipe seal than just one O ring. That is just plain stupid. Is there any way you can install an A/N fitting instead of the O ring ? Even if it means modifying the end of the pipe as well. Good luck with your next engine,and for God's sake,go through it with a fine tooth comb. Happy track time in future.
paul manson mb would cite the EXTENSIVE modding he did to the vehicle as a reason for added stress and it would be good enough for almost every judge, if not every one.
Larry Wilmore Hmm. Perhaps you are right. I suppose the real issue here is to put pressure on the engineering team supervisors not to be stupid with point source failure without warning light backup. Particularly that there is an on board computer capable of decision making in so many hundreds of microseconds. When 1981 model year rolled around and the on board became a reality,there was much talk of 'limp home mode ' . A solenoid could be empowered to trigger the emptying of an accumulator of oil.big warning light,timer,voice,limited power,and things I cannot think of that brighter boys with training can. If I can think of this,the fact that MB has not done some or all is more than bean counting. They should be ashamed of themselves. Look at the complexity of that disassembled engine compared to the 1955 revolutionary Chevy small block. The process engineering required to create the production line much less the engine is something they should be proud of. Not that many decades ago,an F1 engine was less complex. Point source failure is an embarrassment the militaries of the world have been tinkering for many decades. How dare MB allow that here. The more pressure on them the better.
I would say piston side skirt welded to cylinder bore and then your statement about the crank trying to pull the big end of the rod down and snapping out the big end cap is true.
Might pay for e55 owners to replace that rubber o-ring and perform some preventative maintenance. Interesting stuff. Looking forward to the tear down of the new (old) engine
You're telling me that with all the computers etc. there wasn't an oil pressure monitor? You would have known right away if that had been the case. and AMG and Mercedes should be ashamed of themselves for not putting a pressure sensor on the oil system.
Sorry to hear about your engine failure - good detective work finding out the cause. Hope you're back running soon. BTW I've never seen drivers allowed to go on-track without a helmet.
Watching videos like this reminds me of why I elect to drive crappy, old cars that run well. When one breaks in a catastrophic manner, I junk it and buy another crappy, old car that runs well. My $150 Volvo has been going strong for years now. After 20 years of owning "special" cars, I finally learned my lesson.
i have to ask: what weight oil were you running during track use? did you know that the recommended oil for daily/normal use is wholly inadequate for track duty/continuous high speed operation and will thin to the point of allowing the damage you are seeing? it's not the fault of the pump. the factory on the other hand most likely didn't advise accordingly. the reason i bring this up is that this is not the first time i have seen this happen with mercedes engines.
i’m sorry you had to go through this but i’m glad it was someone off your knowledge that was capable of tracking this issue down and finding it because just like you said you would of continued going on thinking that it was some other kind of issue that wasn’t party related
That's astounding that the engineers did not design an oil pressure sensor into the system. Especially on a high-performance engine like this. My W116 has an oil line that runs to the pressure gauge in the dash - super simple, easy to read. It seems that Mercedes vehicles would be invincible without their rubber components - O-Rings, Harmonic Balancer, Engine Mounts, Suspension Bushings, Air Springs - all common problems and all due to the degradation of the rubber compound. And, apparently, the oil system :( Great video but sorry this happened to you. Keep up the excellent work!
The way you pronounce "cylinder" is really distracting me for some reason. Never heard anyone pronounce it like that, but I kind of like it. It makes me a bit angry that an o-ring, something that probably costs pennies, is the reason for an entire being utterly destroyed. It's like a house being burned down because of a single loose wire in one electrical outlet that was caused because of vibration from people walking over time. This is one reason I hate modern engines. There is so many parts, so much complexity, little things could be overlooked and those little things could destroy the engine.
Sir - The fun you have racing has a higher purpose and this is it. Every MB owner of any engine without at least a big red light needs it - also preventative service - and legal if it’s too late. And spare replacement engines properly torn-down and upgraded ready to install. If you can find the smoking gun of engines -mb and others - you have a huge future ! Great 👍 catch.
Great vid, one of my favorite cars. Towards the end of the vid you do mention oil temp. gauge. All through the vid. I kept thinking that you should have added an oil temperature gauge, oil pressure gauge and better oil cooler since you are using the car for time attack. Hard lesson to learn, costly too. Looking forward to your new engine. Stay safe, keep the vids coming.
Very good and thorough analysis of the nonconformities that led to the engine failure. I think that Kevlar reinforcing for their O-rings would help to prevent them from coming apart and becoming a FOD issue, and would be a good engineering improvement for Mercedes in this case. Thanks for the heads up!
Absolutely a great video! Here is my solution! When your MB engine gets older, use a seal conditioner in the oil along with a quart of Motorkote to stop the heat of friction. Of course your application is racing, and most racing engines are torn down after so mile hrs and cycles. So, I would think the average MB owner would see a good o-ring for many more miles.
Great video! So it's a must to change those oil pump O rings when the external oil level sensor starts to lick. I have a 2002 Saab 9-3 with 120k miles, and recently changed all the gaskets, O Rings, etc and I conclude it's the time, the old of the car who plastifies the rubber O rings on the engines and-, of course-, the heat and cold cycles. Also it's a good idea before stops a turbo or intercooled engine to let it COOL down, this way we allow the oil to cool and help those O rings to keep in good shape, but time has no mercy on the rubber, that's why tires manufacturers reccomend to change them, cause they are "old", even if they looks good..
Very interesting video, and quite a spectacular engine fail! Incredible to learn that it doesn't have an oil pressure sensor, the last thing I would have expected from such an expensive car.
That oil pump is so damaged. Something Slammed into that pump, that probably pulled the line out and broke the o-ring. How can you not even acknowledge the massive damage to the oil pump?
WOW great video, very throughout and comprehensive. Would love to see more videos like this. Very shocking Mercedes Benz doesn’t include an oil pressure gauge. Again keep up the great work and keep the videos coming
Oil pressure check light is a must! Gauge is not, but helps you understand whats going on, helps you judge engine and oil state and if you arent pushing the engine too hard...
What awesome forensic work on this. To be honest an Oil Pressure warning would probably come too late, but to have it come on and have a mechanic tell you that it's going to cost upwards of $2Grand to replace the $3.00 O Ring, maybe they left the pressure sensor off on purpose.
With the 2000s came a desire to address concerns from “marketing” that time-tested oil pressure gauges like the one in my A124 were too confusing for people cross shopping Lexus with Benz. Ditto dipsticks and sensible oil change intervals. And it wasn’t just Stuttgart, but also Munich and Wolfsburg that started listening to this nonsense. This is the result! A high-performance car like this should come from the factory with an oil pressure gauge. Period.
Forrest Scott Brinkley Nah, people with money don't want to see anything distracting them from driving. Dropping the oil pressure light in exchange for a low oil level level is much easier on owners. After all, if their cars fail, either it's under warranty or they just buy something else.....smh.
Forrest Scott Brinkley I agree but there are those that aren't interested. There seems to be plenty of very well off people with disposable income destroying more expensive cars than M-Bs and simply buy another one......
F Dryer Perhaps, but AMG being an enthusiast product line, the market niche I believe commands such basic info. The newer cars have at least some of this functionality (albeit buried in a submenu of digital display).
What the hell were they thinking when they designed that thing? Bad enough to use an O-RING to seal the pickup tube (many engines will have them press-fit in with a retaining clamp so they're permanently sealed), but then that pan. I guess the body engineers couldn't be bothered to give them two more inches under the pan to get rid of the front scavenging section.
Well I can confirm that the o-rings for the oil pump do dry up I just took to engines apart and this design is in a lot of 2000 era mercs sooo if you have your oil pan of then I would definitely change it
"O" rings come in different formulations and using the proper one will be able to withstand the oil and heat generated in this engine. However in this critical position , engineers should have used a flange and gasket secured with a bolt-down collar similar to an exhaust pipe connection.
Good info, thank you. Awesome troubleshooting. This is a dilemma for any engines older than "X" years, as most o-ring be it EPDM, Buna, FFKM, Viton, Silicone and what not...have a finite life. I think it will be much safer if we can tear down the engine and replace all o-rings , gaskets and whatever non metallic seals in the engine per "X" years., for those with duty as critical as the -o-ring on your oil pump pick up tube.This will be timed based preventive maintenance no user manual will tell us , but we know it is needed...eventually. I usually change all hoses related to cooling system before it reaches 10 years, or sooner, depending on visual check, but limit is 10 years max. These hoses can be inspected visually without tearing up the engine, that is the lucky part. However, I usually sell my car before its 10th year. I agree the oil pump and pan design in your E55 is scary. I mean, usually we see oil pump being submerged in oil bath and not positioned that high. Also oil pick up pipe with an o-ring like that instead of flanged connection with screws and say paper based gasket or copper gasket. Hope you get your engine fixed fast. Thanks again for sharing.
putting rubber O rings between any liquid connections in extreme environments is a fail, but they do it just for that reason anyways, so that they can fix it or sell you a new car.
Tip for owners replacing that o-ring. Get the same size in a similar durometer in Viton, and it wont happen again. The rubber nitrile ones turn to shit in no time flat in harsh environments.
Nice post mortem investigation. Looks like there may be some room in the sump to block skirt area, to overfill with oil and cover that o-ring joint without coming into contact with the crank throws and foaming the oil as a safety. Having to pull the oil pan to perform a preventive measure is no easy task for the average owner. Since these cars call for full synthetic I'm not surprised it looked good internally despite the heavy duty use and mileage. I don't own an AMG but I'm an auto performance enthusiast and can't believe a car of this stature in performance has no oil pressure sensor on it, not that you would have been able to stop it in time enough to prevent damage under the extreme circumstances. On my high mileage used engine purchases, I pulled the main and rod bearing caps for a bearing condition inspection and sometimes for added feeling of security took the crank and had it polished and then installed new bearings. If they didn't install an oil pressure sensor, what about an engine oil cooler? If not I would certainly put that high on the list of things to do with the replacement motor along with both an oil pressure and temp sensor. That's crucial data for a car that's tracked regularly and driven hard.
This is a very good video. I have also watched the follow up videos of the replacement engine and also installing the pressure gauge (odd why they stopped installing those from factory). The engines I play with also get damaged due to oil issues but it's more so due to some of them being oil burners and people neglecting to check their oil levels. I think an oil level sensor would be a good idea at least for those engines.*Nissan VK45DE* I have looked on Merc forums and I see that the sensor will give a warning in the car -*Engine level. Stop, engine off*. I like the simplicity of that. Not everyone who gets in a car knows that the red light that looks like an genie lamp is a Nissan oil pressure indicator and what to do with it.
Oh, also their oil pump inlets/outlets are 2 flat mating surfaces, not a tube-in design. They do use O-rings as well but they are used like washers, so the inlet is always sealed . 200,000 miles and the O-rings were still rubbery. Nissan did something right.
Yeh the oil level sensor was definitely a good addition in these engines but should have still kept an oil pressure imo. The new o-rings they supply now are a different material so I hope they last longer
My guess is: Lack of lube --> friction --> high temperatures --> detonation (pre-ignition) --> high cylinder pressures at advanced timing --> bent con rod.
A O-ring took out a space shuttle in 1986 too.
For people that haven't seen the previous videos, keep in mind this is a time attack car. I've been using it on the track for the past two years so its been through a lot more stress than most other E55's
My point is that if it happened on this car it might happen on other E55's later down the road, and without an oil pressure sensor or switch there's no way to tell when something like this happens. Its something that could have been easily prevented had I known in time, so Its worth pointing out to others so they don't fall for the same thing.
do you have plans to add some form of oil pressure monitoring in your new engine ?
Yes, already ordered an oil pressure gauge. Will be installing it soon!
Please make video of oil pressure gauge instalation........ Thanks
Wait....There isn't an oil pressure sensor on that motor? My Kawasaki lawn mower engines and my pressure washer have oil pressure switches that shut down the engine if pressure is low. WTF would an engine like this not have at least an idiot light???
Does the S55 have the same O-ring issues even though it has just 1 large oil tank? Thx
The challenger space shuttle also blew cus of a O-ring
Yeah, a lot of bad things can happen when rubber tears.
jospi2 hahahah
Hot damn lol 😂😂😂😂
That's you back up a o ring with rtv it's the fucking space shuttle dude

i belive you can program some aftermarket ECUs to shut the engine down if oil pressure is lost.
how would it know if oil pressure is lost if theres no oil pressure sensor nigga
CashedClean because you tap an oil galley and measure it....nigga
Ronald Rebolledo lmao what a fucking concept right?? It’s a sensor, it can be added
it can, but you need an extra sensor... i test a oil pressure sensor mounted in a oil filter but you need to program quite well because car wont start after oil change.
This could be easily done with an oil pressure sensor and relay logic.

Cars1999 probably wears gloves taking engines apart is easy but know what every part does and how it works may be hard for some people I just turned 18 and I took a corsair flatsix and Chevy v8 and a fzr1000 motorcycle engine head
It's how you care for them. I've been a mechanic for years and years. My hands are good. No gloves. Just some good grit cleaner, a nail brush, and cold water only.
are you a native english speaker?
Beautifully narrated video. Really. He went straight to the point with no drama, gave a ton of information, with no need to draw it out. Obviously he familiarized himself with his subject Before he picked up the camera. Most videos are an agony to watch because of unnecessary yammering, stammering, complete boredom, and some kind of need to be Cecil B. DeMille.. I own an M113k and will be installing a pressure gauge because of the information given on this well done video. Thanks..!
Alot of heartache and life changing events can happen when a rubber breaks!
Lol 🍼👶👶
@@flyboy8282 LOL.
Very impressed with your thought process and technical ability. Very nice investigation here.
This might worry a few Mercedes owners on here.
Might be an idea to ask Alex at LegitStreetCars guy on here, as her is was a Mercedes technician, and certainly knows his stuff.
You got me :( I've got one with 210000kms. I have spent allot of time on the e55 forums and have never heard of this. I'm in panic mode atm. A replacement engine in europe is 5000€.
Agreed, would like to see Alex comment on this. Great video SK8215........think an oil pressure sensor will be on my list for my CLS55 this summer.
learn proper german ,it´s called:"was ist das denn für eine scheisse"
And no it´s not the g-force, if you would know something about the E 55 you would not state such theorys.
ich danke ihnen für ihre warmherzige antwort und wünsche ihnen auch weiterhin alles gute da sie ja ein wahrer intelligenzbolzen sein muessen.
I can't believe how calmly you present this. Good on you.
Great video once again!
You're a fucking hero!
"I just took the engine apart .. ."
THANK YOU VERY MUCH FOR YOUR TIME AND THIS VIDEO,YOU SCARY ME,I HAVE E55 AMG W211...MONDAY I BUY NEW OIL PUMP...ME IN YOUR SITUACION SHAKING HANDS AND MY VOICE IS DIFFERENT....YOU ARE REALLY BRAVE...THANK YOU AGAIN...OH MAN I FEEL THE PAIN IN MY HEART.
I think that you should look at every single o'ring in the new engine not just this one and set a certain time to change all of these again as well. Definitely check out VRPSpeed.
Now we know why 20 year old Mercedes are called classic 👌 in the barn or will blow up
Have you watched "barn find "shows. Classic worth 100k and fist thing they do is say"lets see if she will start "Ho ho ho
You can get gauges that will give you a audible warning. Also hook up some large warning led's in your line of sight when on track. Cool turbo setup!
Good video.
Tought me a lot about selenders.
@Dick Fageroni hahaha
Great video, thanks for sharing.
After a careful and thorough analysis of your dismantled engine, I came to the conclusion that the real cause of the problem has to be that horrendous front spoiler!
I bet you got a good deal on the engine?... They are the LS of the MB world.
Hi from Ireland and 2004 e55 owner great car loads of little bits to do but always puts a smile on my face !! Own 3 Imprezas sti from 94 to 97 and a 07 hatch bought the e55 as a daily driver even though it’s €1800 to tax for the year ! As Andretti said it’s the fastest taxi in the world !
the cl500 ZAS has an oil pressure sensor. it is really easy to retrofit one to any m113k. the spot is already there, just the sensor some gaskets and you got your peace of mind. I got pictures and part numbers if you want to go that route.
Can you please link the part number and pictures? Would REALLY appreciate it... Thanks!
Anoop Patel sure.
A1120150730, housing, mounted on the underside of the oil filter housing, needs m12x1.5 bolts.
N000000001116, bolts as described.
N007603012111, o ring.
A1121840280, gasket.
you may not be able to find it online but any dealership can get you these parts.
If you only fit one oil alert, use a buzzer. You don't have to be looking at the dash at the critical time to get the message. You can also add a pressure gauge and/or warning lamp in parallel. Belt AND suspenders. I used a seat belt buzzer from a crashed Honda.
YES!!! Keeping with the original engine!
I've seen a few oil starvation failures and it never fails to amaze me! The amount of damage an oil starvation causes is catastrophic!
I had a BMW that had been overheated and dropped a valve retainer and the valve hit the piston and it was nothing on that!
A Few points your very good video brings back from memory.
1)For many years race car mechanics have installed a big red warning light to warn the driver of oil pressure failure. A gauge is a good idea,but belt and suspenders here. When driving,keep it simple,you will not be concentrating on gauges.
2)Various race car parts houses sell different designs of oil accumulator,some with the idea of a driver actuated ball valve for a last ditch way to supply oil for a few moments anyway. A good idea here. Try Summit Racing for a start.
3) I would be pissed. At the very least,contact Mercedes-Benz with a polite but very firm letter,paper not electronic. How dare they allow a point source of failure like this. Since it is not backed up with an appropriate idiot light,they are the idiots here. Any American lawyer worth his salt would rub his hands at a potential class action lawsuit here. You will not be the only individual affected here. I would be enraged,not philosophical. Racing does indeed improve the breed.
4) Fix this so that there is a better pipe seal than just one O ring. That is just plain stupid. Is there any way you can install an A/N fitting instead of the O ring ? Even if it means modifying the end of the pipe as well.
Good luck with your next engine,and for God's sake,go through it with a fine tooth comb. Happy track time in future.
paul manson mb would cite the EXTENSIVE modding he did to the vehicle as a reason for added stress and it would be good enough for almost every judge, if not every one.
Larry Wilmore Hmm. Perhaps you are right. I suppose the real issue here is to put pressure on the engineering team supervisors not to be stupid with point source failure without warning light backup. Particularly that there is an on board computer capable of decision making in so many hundreds of microseconds. When 1981 model year rolled around and the on board became a reality,there was much talk of 'limp home mode ' . A solenoid could be empowered to trigger the emptying of an accumulator of oil.big warning light,timer,voice,limited power,and things I cannot think of that brighter boys with training can. If I can think of this,the fact that MB has not done some or all is more than bean counting. They should be ashamed of themselves. Look at the complexity of that disassembled engine compared to the 1955 revolutionary Chevy small block. The process engineering required to create the production line much less the engine is something they should be proud of. Not that many decades ago,an F1 engine was less complex. Point source failure is an embarrassment the militaries of the world have been tinkering for many decades. How dare MB allow that here. The more pressure on them the better.
I would say piston side skirt welded to cylinder bore and then your statement about the crank trying to pull the big end of the rod down and snapping out the big end cap is true.
Wrong, it broke, because it is a modern Mercedes!
Greetings from Germany
Hanz Kranz yup !
ich fahre 3 altbenze....richtig alte...die laufen alle---neubenze sind aber ein grauen
yup Scotty Kilmer hates new Mercedes'es
Do u even know what a “modem Mercedes” is
One of the greatest channels on RUclips!!!
Many Greetings from Germany.
Wow. No oil pressure switch is just silly. A lot of trust huh amg?
Might pay for e55 owners to replace that rubber o-ring and perform some preventative maintenance. Interesting stuff. Looking forward to the tear down of the new (old) engine
jrbuch ideally all rubber type parts should be replaced every couple of years.
That'd cost a fortune no doubt.
You're telling me that with all the computers etc. there wasn't an oil pressure monitor? You would have known right away if that had been the case. and AMG and Mercedes should be ashamed of themselves for not putting a pressure sensor on the oil system.
nisssan and toyota must be laughing in Japanese dialect...
fidel catsro I’d be laughing at Nissans reliability
yes after 2009 Nissan joined with Renault it became question...before that it was a great name
Sorry to hear about your engine failure - good detective work finding out the cause. Hope you're back running soon. BTW I've never seen drivers allowed to go on-track without a helmet.
"keep in mind this is a time attack car. I've been using it on the track for the past two years"
Every engine could brake after this .....
Watching videos like this reminds me of why I elect to drive crappy, old cars that run well. When one breaks in a catastrophic manner, I junk it and buy another crappy, old car that runs well. My $150 Volvo has been going strong for years now. After 20 years of owning "special" cars, I finally learned my lesson.
i have to ask:
what weight oil were you running during track use?
did you know that the recommended oil for daily/normal use is wholly inadequate for track duty/continuous high speed operation and will thin to the point of allowing the damage you are seeing? it's not the fault of the pump. the factory on the other hand most likely didn't advise accordingly.
the reason i bring this up is that this is not the first time i have seen this happen with mercedes engines.
i’m sorry you had to go through this but i’m glad it was someone off your knowledge that was capable of tracking this issue down and finding it because just like you said you would of continued going on thinking that it was some other kind of issue that wasn’t party related
That sucks, that entire engine is shot, that's going to hurt the wallet.
Now he has a spare supercharger.
jospi2 not really if it seized up cuz of the nom-existend oil flow..
m113s are cheap. most go for well over 400k miles without any issues. its in the SLR running over 600bhp
+ardi du Unlike turbochargers, superchargers don't require an external oil source.
halofreak1990 alright, didn‘t knew, since i never saw a Supercharger in real life, are they equipped with ball / cylinder bearings instead?
That's astounding that the engineers did not design an oil pressure sensor into the system. Especially on a high-performance engine like this. My W116 has an oil line that runs to the pressure gauge in the dash - super simple, easy to read.
It seems that Mercedes vehicles would be invincible without their rubber components - O-Rings, Harmonic Balancer, Engine Mounts, Suspension Bushings, Air Springs - all common problems and all due to the degradation of the rubber compound. And, apparently, the oil system :(
Great video but sorry this happened to you. Keep up the excellent work!
They are made to fail
The way you pronounce "cylinder" is really distracting me for some reason. Never heard anyone pronounce it like that, but I kind of like it.
It makes me a bit angry that an o-ring, something that probably costs pennies, is the reason for an entire being utterly destroyed. It's like a house being burned down because of a single loose wire in one electrical outlet that was caused because of vibration from people walking over time. This is one reason I hate modern engines. There is so many parts, so much complexity, little things could be overlooked and those little things could destroy the engine.
Sir - The fun you have racing has a higher purpose and this is it. Every MB owner of any engine without at least a big red light needs it - also preventative service - and legal if it’s too late. And spare replacement engines properly torn-down and upgraded ready to install.
If you can find the smoking gun of engines -mb and others - you have a huge future ! Great 👍 catch.
Put a LS engine in it Save your self tons of money
Great vid, one of my favorite cars. Towards the end of the vid you do mention oil temp. gauge. All through the vid. I kept thinking that you should have added an oil temperature gauge, oil pressure gauge and better oil cooler since you are using the car for time attack. Hard lesson to learn, costly too. Looking forward to your new engine. Stay safe, keep the vids coming.
it's cylinder, not sullinder
Dude...what a heck!!! What a mess!! Great video and advise for all E55 owners...congrats !!!!!!!!
2jz swap!
Jarek LS
😂🤣😂 2J all the things!
Very good and thorough analysis of the nonconformities that led to the engine failure. I think that Kevlar reinforcing for their O-rings would help to prevent them from coming apart and becoming a FOD issue, and would be a good engineering improvement for Mercedes in this case. Thanks for the heads up!
Benz is over priced junk.. always has been..
*sent from an iPhone
ya sound like a poor
I guess that‘s why you where named Dick.
That's why no one buys German cars.
You know that „American v8“ are made in Germany, too? Eisenwerke Brühl near cologne puts out thousands a year.
Absolutely a great video! Here is my solution! When your MB engine gets older, use a seal conditioner in the oil along with a quart of Motorkote to stop the heat of friction. Of course your application is racing, and most racing engines are torn down after so mile hrs and cycles. So, I would think the average MB owner would see a good o-ring for many more miles.
Damn dude, awesome engine analysis. A man who clearly knows wtf he’s on about
Great video! So it's a must to change those oil pump O rings when the external oil level sensor starts to lick. I have a 2002 Saab 9-3 with 120k miles, and recently changed all the gaskets, O Rings, etc and I conclude it's the time, the old of the car who plastifies the rubber O rings on the engines and-, of course-, the heat and cold cycles. Also it's a good idea before stops a turbo or intercooled engine to let it COOL down, this way we allow the oil to cool and help those O rings to keep in good shape, but time has no mercy on the rubber, that's why tires manufacturers reccomend to change them, cause they are "old", even if they looks good..
I have a 1989 Suzuki Swift 1.3 liter dohc with 419000 miles or 674315.136 kilometers and still going strong.
Very interesting video, and quite a spectacular engine fail! Incredible to learn that it doesn't have an oil pressure sensor, the last thing I would have expected from such an expensive car.
That oil pump is so damaged. Something Slammed into that pump, that probably pulled the line out and broke the o-ring. How can you not even acknowledge the massive damage to the oil pump?
Are you fucking stupid or just trolling?
WOW great video, very throughout and comprehensive. Would love to see more videos like this. Very shocking Mercedes Benz doesn’t include an oil pressure gauge. Again keep up the great work and keep the videos coming
Oil pressure check light is a must! Gauge is not, but helps you understand whats going on, helps you judge engine and oil state and if you arent pushing the engine too hard...
I love engines, don't know much about them though as I'm not a mechanic. Really enjoyed this video, you're so skilled
What awesome forensic work on this. To be honest an Oil Pressure warning would probably come too late, but to have it come on and have a mechanic tell you that it's going to cost upwards of $2Grand to replace the $3.00 O Ring, maybe they left the pressure sensor off on purpose.
Gods of speed demand sacrifices from here to there! Great vid, even though it sucks that your engine was lost in the process.
With the 2000s came a desire to address concerns from “marketing” that time-tested oil pressure gauges like the one in my A124 were too confusing for people cross shopping Lexus with Benz. Ditto dipsticks and sensible oil change intervals. And it wasn’t just Stuttgart, but also Munich and Wolfsburg that started listening to this nonsense. This is the result! A high-performance car like this should come from the factory with an oil pressure gauge. Period.
Forrest Scott Brinkley Nah, people with money don't want to see anything distracting them from driving. Dropping the oil pressure light in exchange for a low oil level level is much easier on owners. After all, if their cars fail, either it's under warranty or they just buy something else.....smh.
F Dryer I would contest that for AMG buyers. They are typically “car people” and would most likely welcome the valuable info.
Forrest Scott Brinkley I agree but there are those that aren't interested. There seems to be plenty of very well off people with disposable income destroying more expensive cars than M-Bs and simply buy another one......
F Dryer Perhaps, but AMG being an enthusiast product line, the market niche I believe commands such basic info. The newer cars have at least some of this functionality (albeit buried in a submenu of digital display).
What the hell were they thinking when they designed that thing? Bad enough to use an O-RING to seal the pickup tube (many engines will have them press-fit in with a retaining clamp so they're permanently sealed), but then that pan. I guess the body engineers couldn't be bothered to give them two more inches under the pan to get rid of the front scavenging section.
Very good tear down. Apparently Mercedes sourced their O-rings from the same place NASA did with the Challenger space shuttle.
man just the fact tht you twin charged your e55 is super dope
Thanks for this video! im going to change the o-ring and add an oil pressure guage and visual audible warning while it is in my shop for the winter.
I don't own a Mercedes however very educational and to know this kind of issues existing on AMG engine. Great video
From some reason they removed oil pressure sensors since 1998.the threadhole for the sensors should be there and blocked of
Well I can confirm that the o-rings for the oil pump do dry up I just took to engines apart and this design is in a lot of 2000 era mercs sooo if you have your oil pan of then I would definitely change it
Very nice, not the blown up engine but tracing the cause. Cheers.
Now III watch you second engine fail and see your take on that !! Cheers again.
Hmm.. i think its Mercedez flaw design... Wow.. really appreciate ur explanation, very clear to average people like me.. Nice Bud! Subscribed 😎
Not an owner of this brand but very informative video and info. Thanks.
"O" rings come in different formulations and using the proper one will be able to withstand the oil and heat generated in this engine. However in this critical position , engineers should have used a flange and gasket secured with a bolt-down collar similar to an exhaust pipe connection.
Wow. You spun out quickly. In your own oil I'll bet. What a bummer losing the engine due to one o-ring.
oh man great tear down.. that o ring.. i have a ml430 hope it does not have a o-ring like that.
your doin great work
Good info, thank you. Awesome troubleshooting. This is a dilemma for any engines older than "X" years, as most o-ring be it EPDM, Buna, FFKM, Viton, Silicone and what not...have a finite life.
I think it will be much safer if we can tear down the engine and replace all o-rings , gaskets and whatever non metallic seals in the engine per "X" years., for those with duty as critical as the -o-ring on your oil pump pick up tube.This will be timed based preventive maintenance no user manual will tell us , but we know it is needed...eventually.
I usually change all hoses related to cooling system before it reaches 10 years, or sooner, depending on visual check, but limit is 10 years max.
These hoses can be inspected visually without tearing up the engine, that is the lucky part. However, I usually sell my car before its 10th year.
I agree the oil pump and pan design in your E55 is scary. I mean, usually we see oil pump being submerged in oil bath and not positioned that high. Also oil pick up pipe with an o-ring like that instead of flanged connection with screws and say paper based gasket or copper gasket.
Hope you get your engine fixed fast. Thanks again for sharing.
Right on man! Glad to hear your keeping it AMG power! Keep us posted.
Is there a wireless blue tooth oil sensor?
Such good analysis. I admire your knowledge sir.
putting rubber O rings between any liquid connections in extreme environments is a fail, but they do it just for that reason anyways, so that they can fix it or sell you a new car.
Tip for owners replacing that o-ring. Get the same size in a similar durometer in Viton, and it wont happen again. The rubber nitrile ones turn to shit in no time flat in harsh environments.
Nice post mortem investigation. Looks like there may be some room in the sump to block skirt area, to overfill with oil and cover that o-ring joint without coming into contact with the crank throws and foaming the oil as a safety. Having to pull the oil pan to perform a preventive measure is no easy task for the average owner. Since these cars call for full synthetic I'm not surprised it looked good internally despite the heavy duty use and mileage.
I don't own an AMG but I'm an auto performance enthusiast and can't believe a car of this stature in performance has no oil pressure sensor on it, not that you would have been able to stop it in time enough to prevent damage under the extreme circumstances. On my high mileage used engine purchases, I pulled the main and rod bearing caps for a bearing condition inspection and sometimes for added feeling of security took the crank and had it polished and then installed new bearings.
If they didn't install an oil pressure sensor, what about an engine oil cooler? If not I would certainly put that high on the list of things to do with the replacement motor along with both an oil pressure and temp sensor. That's crucial data for a car that's tracked regularly and driven hard.
I just replaced the O ring on the fluid pick up on my 65 Corvair's automatic transmission because that's what you do when you replace the pan gasket.
This is a very good video. I have also watched the follow up videos of the replacement engine and also installing the pressure gauge (odd why they stopped installing those from factory).
The engines I play with also get damaged due to oil issues but it's more so due to some of them being oil burners and people neglecting to check their oil levels. I think an oil level sensor would be a good idea at least for those engines.*Nissan VK45DE*
I have looked on Merc forums and I see that the sensor will give a warning in the car -*Engine level. Stop, engine off*. I like the simplicity of that. Not everyone who gets in a car knows that the red light that looks like an genie lamp is a Nissan oil pressure indicator and what to do with it.
Oh, also their oil pump inlets/outlets are 2 flat mating surfaces, not a tube-in design.
They do use O-rings as well but they are used like washers, so the inlet is always sealed . 200,000 miles and the O-rings were still rubbery. Nissan did something right.
Yeh the oil level sensor was definitely a good addition in these engines but should have still kept an oil pressure imo. The new o-rings they supply now are a different material so I hope they last longer
At Mercedes I've found they keep their cards close to their chest on some issues.
Great Work , Great Vid..
Good and systematic investigation to the root cause. Well done!
seems like you would have heard those rods hammering well before
it went into self distruct mode !
Well, he said he didn't.
My guess is:
Lack of lube --> friction --> high temperatures --> detonation (pre-ignition) --> high cylinder pressures at advanced timing --> bent con rod.
