[@InsideOfMyOwnMind]

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 👍

[@410kane]

My Clk500 doesn't have a dipstick. You have to believe in a sensor that sends info to the dash about oil level. Great job mercedes👏

[@xfmotorsports]

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.

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.

[@derbigpr500]

Cars1999 You can't really compare some 2 liter 4 cylinder that's so simple nothing on it can go wrong to something as complex as this V8 in the E55.

[@xfmotorsports]

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.

[@joel50i]

do you have plans to add some form of oil pressure monitoring in your new engine ?

[@xfmotorsports]

Yes, already ordered an oil pressure gauge. Will be installing it soon!

[@devanandgovindshetdessai4063]

[@freakasis]

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???

[@curlymyhero]

Does the S55 have the same O-ring issues even though it has just 1 large oil tank? Thx

[@MirchiBoy]

I was ready to blame it on the boost or the tune. I shouldn't have doubted your skills. Lol. Thank you for your findings.

[@UgurAkdag]

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.

[@CarsExposed]

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 ... 😳

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. By the way if you are using your car to the race track you can modify also the oil thermostat it's very easy on M113k. Sorry for your loss

[@xfmotorsports]

Hey Tasos, Thanks for your comment. I also recently discovered your channel. Great content on these engines! Pretty surprising none of the newer models come with oil pressure sensors or switches considering that was something almost all older Mercedes had

[@bounderchris]

I have an 06 S55 with about 30k into it.. 5k in the exhaust alone.. is this an issue on the S too? I realize they don’t have oil pressure sensors but I am talking about the o ring. I know the oil systems / sump Design is totally different

[@Rockport1911]

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...

[@avii5429]

Thanks for not clickbaiting me, you actually explained it immediately, so many youtubers can actually learn something from you.

[@inox1ck]

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!

[@dougjohnson9948]

I can't believe how calmly you present this. Good on you.

[@PlaneEasy]

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.

[@JanicekTrnecka]

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...

[@paulmanson253]

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.

[@TheMoreCylindersTheBetter]

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.

[@paulmanson253]

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.

[@gizmothewytchdoktor1049]

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.

[@davidcisneros1429]

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!

[@NotSoCrazyNinja]

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.

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..

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.

[@seancain7305]

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!

[@suryaprihadi2258]

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.

man just the fact tht you twin charged your e55 is super dope

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.

my uncle was a mercedes mechanic before he passed away. said theres an issue with the low oil sensors in the older mercs. especially if the oil pressure sensor orfice is blocked with carbon from old oil (think extended oil change intervals)...

[@danistheman9055]

Right on man! Glad to hear your keeping it AMG power! Keep us posted.

[@lubakaczmar3198]

Is there a wireless blue tooth oil sensor?

[@azargelin]

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 good troubleshooting !

[@dannoi]

OMG ! sorry man and thank you so much for this video ! its invaluable info for any E55 owner or any other dual sump m113k

[@mahannaidu5228]

Perhaps two o rings should in two separate groves would be an idea, Mercedes please take note. ,,a very good video.

[@ezpz4659]

This man is so brilliant.

[@mysock351C]

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.

My guess is: Lack of lube --> friction --> high temperatures --> detonation (pre-ignition) --> high cylinder pressures at advanced timing --> bent con rod.

Very valuable information! Thank you

Gods of speed demand sacrifices from here to there! Great vid, even though it sucks that your engine was lost in the process.
