a tip to keep the timing chain a bit longer is to decrease the service intervall. Not 2500 miles (25.000 km) and 2 year. 1 year and around 1500 miles. More frequent oil changes - that is what i have red in BMW groups and forums.
@Dan Tallsten Sorry for being confusing. It is counted as in a swedish/european mesurement. The context is just to decrease the service intervall to around the half of what BMW is saying for diesel models. Then ofc. if a car has been driven for around 300.000 km and the chain snaps its caused by ware. The lifetime of a car 200.000 - 300.000 km, all above this is more or less on borrowed time. Everything can happen on these high milage cars.
To all who believe that n57 has no timing chain problem: yes it has. You need to be careful after 200kkm and to be calm replace it soon. I did it on 230kkm, the chain in my car could be already heard at aprox 2200 rpm, it sounded like chain was rubbing into something. After original bmw chain kit replacement (I replaced also few other parts preventively) engine now runs and sounds like new and also gearbox shifts smoother because everything is tight. So do not be fooled with n57 wrong belief. If you drive long distances you can replace it maybe after 300kkm, the most affected engines are those who have normal short trips - meaning way more starts of the engine (starting the engine is the hardest for the chain). And do not replace only chain kit, replace also the rod bearings. COST: I payed around 2k eur in total for - original bmw timing chain set, rod bearings, crankshaft pulley, and few other smaller parts, work. The pulley was expensive (around 500 eur), rod bearings are not but then it takes so much more labour hours to replace it and at the end the number was quite high. Also replace the engine mount since the engine is outside (I already replaced it around 20kkm before so no need now). Now car really rides nice and I will keep it for next three years or something like that👌
The problem is, not the rod bearings failing but the big end bearings. I just did my timing on my N47. pulled the engine and checked all the bearings. 187000 km and the rod bearing are fine but the big end was worn. Brown color. No marks or anything like that but the bearing surface was gone. Also you need to clean the egr and the intake including the intake channels in the cylinder head.
@@Nut_Job. I just sold my E61 2.5d and bought the F11 2.0d. Hmmm one of the BMW's best engine and the worst. I never had any problem with the 525 engine.

Crankshaft bearings, balancing rod bearings, the timing disaster, the chain sprockets on the crankshaft, high pressure pump, egr issues, etc... Disaster.
Scary how many modern cars have timing chains that snap nowadays, I remember a car with a timing chain was always deemed virtually unbreakable years ago, from what I understand modern engines are designed to break the rocker arms instead of bending/ breaking a valve, hope you sort it ok.

I don't think you are going to have any damage to the pistons or valves at all. Those rocker arms are designed to break as they have. This is a design feature that BMW and other manufacturers are now using to reduce the amount of damage to other components should a belt or chain break.

I know it probably will be, but let's hope it isn't too expensive. What else could you buy in terms of engineering for the price of the engine rebuild.
I had a neighbour who had a BMW 7 series which he bought new. His timing chain went after 18 months. On contacting the local BMW dealer he was told they would take it in no bother but he couldn’t say how long they would be to fix it as there was quite a few vehicles with the same problem ahead of him!!!. He asked why the timing chain was designed to be at the rear of the engine and was told they don’t consider it to be a service item. .???? So much for German engineering?
German engineering is terrible. These cars are sold on badge merit only, they will always give horrendous problems, but the British are absolute suckers for them for some strange reason ? The most bulletproof cars I've ever owned are Japanese, Lexus and Honda exec saloons can frequently do a quarter of a million miles without any major problems. But lessons are never learned.
To be honest, it’s funny how your confidence can grow the more you work on something. I’ve done all this on other engines before, but when faced with a BMW that doesn’t look familiar I was initially a bit worried... but if you have to pull everything on/off a few times you’ll be surprised how ‘familiar’ it all begins to feel! That’s also the reason I began recording myself at the very start on the Range Rover - to retrace my steps if needed 👍
Proper engine oil change every ~10k miles (every year if 10k is not reached) with good oil & filters and you won't see any problems with timing chains (keeping in mind that timing chain is in good condition), same goes for N47 and etc. People took BMW's "life long" term way too serious - there are numerous examples where people took their diesel e90, e60, f10. for first service after 50k+ miles. I haven't heard of engine oil that can withstand and retain it's ability to properly lubricate after 50k miles. It is always sad to hear people blaming BMW for weak chains because, I believe, chains were designed to withstand any possible load that engine can deliver under optimal condition (taking into account proper vehicle services). However, there is one thing BMW can be blamed for, and that is: for trusting new car owners too much. People can be way too reluctant when talking about doing regular services to brand new cars. Why to bother with services if you are getting new car next year? Sadly problem arises to those whom can't afford brand new cars and buy second-handed ones. That was my opinion, feel free to disagree, just wanted to share my two cents. Have a great day all!
While I agree there’s plenty of truth in what you’ve said there, this particular timing chain failure can’t really be down to this because it’s an ex-police traffic car & has had extremely frequent oil changes. I do think the design of the N47/N57 onwards is a bit weak & not designed for seriously long life’s (beyond ~160/200k miles) unfortunately - if you compare with older BMW engine designs or even other manufacturers you can see it. I also think start/stop technology is not good for engines at all. I’m not really upset or mad with BMW but it just seems to be the way the company is headed - customers are well out of warranty by 150k+ so why do they care then? 🤷♂️
@@Nut_Job. One thing is for sure that BMW saved some $ while making chains weaker. I didn't had intention to sound like I'm forwarding my comment directly at you. I just read a bunch of comments and noticed the general trend that I'm tired off. Of course there are many more variables, regarding use of vehicle, that affect components' increased wear and tear, therefore timing chain being one of the more popular parts to break it is pretty easy to tell that there is something wrong with it. And as you mentioned, even regular oil changes might not save it.
@@Nut_Job. Agree. Having to drop engine, remove gearbox, clutch and flywheel takes time. Although if you have car lift that gives enough clearance you can service timing chain by tilting engine on the mounts.
Well done on looking, then passing it on. I doubt if have got as far as you before passing it on. On a separate note, it's nearly end of summer, lots of bargains in the shops, possibly including a gazebo? Would be handy for working under if the weather is a bit typical
Do you think I that the rockers breaking would release the tension off the valves so when the piston hit the valves would not bend valves. Fingers crossed for ya son.
Interesting thing with the N57 is that the inlet + exhaust valves are pretty much vertical with the piston in their alignment. Which suggests to me that they shouldn’t really bend much, but yes they smash the rocker arms to pieces
Bad luck on the timing chain.. but you’ve made the right decision to pass it on. I’m the same as you, if I have the equipment, I’d give it a go... but time is better spent in other areas! Think of it as great content... it’s a shame... but I’m in for the full resolution 👍🙂
Sometimes those rockers are sacrificial so fingers crossed, agree re letting specialists do it, sometimes although you probably could eventually fix it and cobble it all back together, is it worth the hassle and cost of tools v paying someone who has the equipment time and knowledge to do it. From bitter experience and despite brief satisfaction of DIY I wish some jobs I’d left to the pros.
Fix it yourself surely it will be only 530d timing chain rebuild for the home mechanic? And very similar to n47 engine so info applies to them. Used to work at German car specialist it’s a massive job
To be honest, I’m having that change of heart now... I’m already this far, so I’m working out how to do it myself on the driveway. First job is to get the head repaired, head gasket + bolts, timing chain kit... and how to physically do it from underneath by removing gearbox. That’s the way I think im going now anyway - forget what I said in the last video 👍😬
Shame as you put so much effort in to car but right decision at this stage Why bmw haven’t fitted updated tensioner kit as part of recall is beyond belief , not fair that these things are ticking time bombs
Nutjob made this repair far more difficult than needed and the heath robinson ramps and gearbox removal method risked a severe crush injury. Once the broken timing chain had been found that could have been replaced from the top of the engine without needing to remove the transmission. Use the old broken chain to feed in a new one that is then riveted together. Some special tools needed or take the car to an indy. The timing chain is the weaker one of the two so likely to have broken, not the lower chain which is sized for driving the HP fuel pump and the camshafts.
OMG... just no 😩 At no point was a ‘crush injury’ a possibility. I fail to see a problem with ramps as cars have been worked on ramps since before you & I were born. At no point was I beneath the transmission during removal either - the only risk really was to my actual transmission if it were to become unbalanced perhaps & fall? Then that’s my problem really... As for feeding a chain back around the HPFP sprocket from the top of the engine... 😂😂😂 I’m sorry but I just don’t think that’s remotely possible - especially after the chain has snapped & flung itself somewhere... Mending an N57 timing chain is either an engine-out job, or a transmission-out job so that all 3 (probably stretched) chains can be renewed. By all means though, if I’m wrong I would definitely subscribe to someone who posts a timing chain repair video from the top as you describe 👍
@@Nut_Job. Yes, because the BMW TIS method for replacing the timing chain is from the top of the engine, not via the transmission. I noticed you had access to the TIS, I'm puzzled why you took the more difficult route?
@@Nut_Job. If the broken timing chain was not still in one piece then sure best to find all the pieces if possible. But hopefully any loose links would have dropped to the sump. On a high mileage car replacing all three chains is not a bad idea but that does mean removing the transmission - not sure I would have gone to that trouble. BTW on my 530d the HP fuel pump seals went leaking diesel into the sump which caused a high oil level warning. Had the £1000 pump replaced under warranty which I think is possible without removing the back cover off the engine to disconnect the drive sprocket.
Apologies, you are correct - there is a procedure for replacing just the top timing chain without engine or transmission removal on www.newtis.info. This wouldn’t have worked in my situation unfortunately, as the chain had already failed & flung itself around 👍
Well, No. I like the E39 veeery much, but the 530d M57 is, when you buy /bought it, also worth to look at the high pressure pump, vacuum pump, renew complete vacuum system, check injectors, turbocharger, remove "drallklappen" from the intake manifold, clean the intake manifold, check agr valve, thermostat and then you have to deal with the typical rust problems of the E39, specially the tourings have a fatal rust problem at the trunk lid. When it's a 30dA with the automatic tranny, then you will sooner or later repair that thing too. Timing chain can also be a problem. I'd take a F10 rather than a E39 if you want a car that drives without worrying for a good while about repairs and rust. When you really want a E39, pick a good example, check for rust and any odd behaviour of the engine and any noise and buy it. But be prepared: Can be cost a lot of money, but you also might be lucky and the good ol E39 is only taking its regular oil changes and typical service parts...:D (Honestly I like my E39, cost me about 4-5k€ in repairs so far, parts and also some optical additions).
I am wondering what those plastic parts inside the engine will look like after 20 years, seeing all heat cycles and chemicals. My car is 20 years old and many interior trim parts are brittle as hell. Planned obsolescence. By the way - what was the reason for the chain to snap?
I guess it failed due to the mileage?... it’s at about 164k miles I think, but I still think that’s a crap design imo. I don’t have a major problem with the mixture of materials being used today; alloys, plastic/composites - even metal alloys fail due to stress fatigue over time. The problem is the difficulty accessing these parts to perform the service jobs - it’s just short-sighted engineering, basically saying “not our problem when it’s out of warranty” 🤨
@@Nut_Job. normally the chains would elongate due to wear, throwing a code for camshaft timing. Very unfortunate yours snapped. Good luck with the repair!
This is the N57 engine, so it’s not quite the same as the M57. It’s a 2012 F11 model with ~200k km on the clock. No timing chain lasts forever though, so I’d be inclined to get yours checked at least if you’ve got 650k on the clock...
Nut Job i wash so shocked about iT that i saw the title for M57 Instead of N57... the N57 from 2008-2011/12 has this kind of issues ... the first line of M57 is so robust! The chains don’t fail hardly as often by the 2.0d diesels
to days diesel engines are less reliable. due by disign of the timming chain only being a single chain instead of being douplex .wether it is done on purpose i do not know? also i do not believe it is any advantage being at the back of the engine , it is just more expensive to repair . i believe there is a double chain mod available ?
Because its meant to be maintenance free for the cars lifetime however what they dont say is that they only consider the lifetime of the car to be 60-100k miles

Hi there, did you have classic symptoms before the chain snapped such as rattling etc. or did it just snap without warning? I have a well maintained N57 on 120k miles and I'm not sure if I should change mine just to be safe.
I don’t remember hearing anything particularly worrying before it snapped. Maybe there was a tiny sound I didn’t pick up on, but who knows? 🤷♂️ At 120k I wouldn’t be worried, but I would start planning for the top chain replacement at the very least. It’s not a massive job like mine was….
@@Nut_Job. thanks for replying, love all of your F11 videos by the way, really helping me out with my F10 preventative maintenance jobs. I won't do chain DIY but will aim to get it done definitely before 150k for some peace of mind.
Chris Atkinson Well the whole point of a timing chain is that it shouldn’t really have to be replaced (provided the oil is kept changed and you don’t do half a million miles) so putting it at the back of the engine probably wasn’t seen as an issue. The flaw was in the chains used I think!
@@owenb1t5014 the soft chain and srocket is a feature... it just dies not serve owners. For the same cost you could have proper timing components to drive your money worth out of these money-pits
I know... 🤔 Its certainly something to bear in mind if buying almost any modern BMW in my opinion. The 2.0d N47 engines have a far worse reputation by all accounts... if I’d perhaps done my homework a bit better I could have done the timing chain immediately... hindsight is a great thing eh
Loads of timing chains are moving though. Mercedes new inline six has it at the rear. It is all to do with getting the engine low enough for pedestrian impact and less metal being higher in the engine bay

No they tell you Diesel engine needs to be change 120k (km) Gasoline engine 160(km).im asking that at how much Mileage this happened to you.I know a X6 that driven 210k(km) with first timing chain and it broke down.
The chains & guides are all apparently an ‘upgraded’ design - whatever that means? Who knows, but it should at least do another 100k, or I’ll be real mad 😡
It is more the guides that take the stress the chain tensioner changed. BMW b series b47 and 57 share the exact same chain part number, oil sprayer etc. Only a few guides are different in design terms as the final n series engines following the timing chain issues
This is caused by poor maintenance. These engines with proper maintenance are bullet proof. Change oil every 10 000kms with quality oil and you can't go wrong
This was an ex-police traffic car. If you think poor maintenance is the issue then you need to look a little closer. You’ve actually been lucky, rather than the rule. Just look at the pathetic size of the top chain, plus the extremely awkward positioning at the back of the engine. Longevity has slipped down the priority list for BMW since previous generations of engines…. in the name of efficiency & emissions reduction. There’s always a trade off 🤷♂️
Those 2 white cords you have around your neck hanging in the engine are a recipe for disaster or even DEATH tuck them away man image getting them caught up with the engine running it would strangle you?
That’s a reasonable point 👍 However, in this video my engine has a broken timing chain so there’s very little (no) chance of anything turning in this engine right now. I would certainly avoid wearing anything loose like that when inspecting a running engine though 👍
If the car is working normally I think the gearbox should allow you to select Neutral (not 100% sure…) However, if you need to ‘force’ the car into Neutral like I did then you can do that from underneath the vehicle. On the left-hand side of the gearbox you will see a vertically mounted bolt. Above the bolt is a small lever, so that as you tighten the bolt it will push the lever - this will force the gearbox into Neutral. When you tighten the bolt you will hear a ‘clunk’ noise & you should then be free to push the car around. Undo the bolt & the box will re-engage normal gearing 👍

Oh that’s a shame! Are you changing all the high pressure fuel rail parts? If I remember correctly, the concern with a HPFP failure is tiny metallic contamination of the fuel rail/system… even the fuel tank (because of fuel return line?) needs checking/clearing doesn’t it? At least it’ll need new timing chain etc. so you can give it some extra years. I would also advise replacing the oil pump too 👍
@@Nut_Job. the stainless steel lines I'm going to try to clean then examine with microscope or something . And there a 1 micron aftermarket filter I can install at the HPFP so I don't have to change the fuel tank
someone suggested it was a harmonic given off by the flywheel/torque converter that stresses the chains more than if it were on the front of the engine. I'de like to give the engineer that moved the chain to the back a good swift kick in the nuts

Great video. Was wondering at what point you might think ‘I’ve taken this as far as I can’ and think it’s a good decision to get it finished by a pro.

I swapped my 2008 e60 530i for a 2004/05 e60 525d as they still have the older m57 engine with the timing chain in the correct position. Old skool 4 life. Enjoy your 4k bill
What about the swirl flaps that some m57's ingested.

I know it probably will be, but let's hope it isn't too expensive. What else could you buy in terms of engineering for the price of the engine rebuild.
Please put in description how many km/mi is on this chain!?
I had a neighbour who had a BMW 7 series which he bought new. His timing chain went after 18 months. On contacting the local BMW dealer he was told they would take it in no bother but he couldn’t say how long they would be to fix it as there was quite a few vehicles with the same problem ahead of him!!!. He asked why the timing chain was designed to be at the rear of the engine and was told they don’t consider it to be a service item. .???? So much for German engineering?
German engineering is terrible. These cars are sold on badge merit only, they will always give horrendous problems, but the British are absolute suckers for them for some strange reason ? The most bulletproof cars I've ever owned are Japanese, Lexus and Honda exec saloons can frequently do a quarter of a million miles without any major problems. But lessons are never learned.
It is on the rear to reduce noise. But it doesn ´t work
Did he mention how many kms he had on it?
Plastic fantastic BMW engineering. Hate working on BMW. Ut good effort!
I’m beginning to feel that way...
Zed Man
Are BMW cars any worse than Audi or Merc of a similar year ?
you have bigger balls than me..... i wouldn't have even got to this stage of stripping it down lol.... good luck with the fix dude
To be honest, it’s funny how your confidence can grow the more you work on something. I’ve done all this on other engines before, but when faced with a BMW that doesn’t look familiar I was initially a bit worried... but if you have to pull everything on/off a few times you’ll be surprised how ‘familiar’ it all begins to feel!
That’s also the reason I began recording myself at the very start on the Range Rover - to retrace my steps if needed 👍
Proper engine oil change every ~10k miles (every year if 10k is not reached) with good oil & filters and you won't see any problems with timing chains (keeping in mind that timing chain is in good condition), same goes for N47 and etc. People took BMW's "life long" term way too serious - there are numerous examples where people took their diesel e90, e60, f10. for first service after 50k+ miles. I haven't heard of engine oil that can withstand and retain it's ability to properly lubricate after 50k miles.
It is always sad to hear people blaming BMW for weak chains because, I believe, chains were designed to withstand any possible load that engine can deliver under optimal condition (taking into account proper vehicle services). However, there is one thing BMW can be blamed for, and that is: for trusting new car owners too much. People can be way too reluctant when talking about doing regular services to brand new cars. Why to bother with services if you are getting new car next year? Sadly problem arises to those whom can't afford brand new cars and buy second-handed ones.
That was my opinion, feel free to disagree, just wanted to share my two cents. Have a great day all!
While I agree there’s plenty of truth in what you’ve said there, this particular timing chain failure can’t really be down to this because it’s an ex-police traffic car & has had extremely frequent oil changes. I do think the design of the N47/N57 onwards is a bit weak & not designed for seriously long life’s (beyond ~160/200k miles) unfortunately - if you compare with older BMW engine designs or even other manufacturers you can see it. I also think start/stop technology is not good for engines at all.
I’m not really upset or mad with BMW but it just seems to be the way the company is headed - customers are well out of warranty by 150k+ so why do they care then? 🤷♂️
@@Nut_Job. One thing is for sure that BMW saved some $ while making chains weaker.
I didn't had intention to sound like I'm forwarding my comment directly at you. I just read a bunch of comments and noticed the general trend that I'm tired off.
Of course there are many more variables, regarding use of vehicle, that affect components' increased wear and tear, therefore timing chain being one of the more popular parts to break it is pretty easy to tell that there is something wrong with it. And as you mentioned, even regular oil changes might not save it.
Totally 👍
Also, putting it at the back of the engine didn’t help either...
@@Nut_Job. Agree. Having to drop engine, remove gearbox, clutch and flywheel takes time. Although if you have car lift that gives enough clearance you can service timing chain by tilting engine on the mounts.
Well done on looking, then passing it on. I doubt if have got as far as you before passing it on.
On a separate note, it's nearly end of summer, lots of bargains in the shops, possibly including a gazebo? Would be handy for working under if the weather is a bit typical
Btw HSS hire out engine cranes over the WE for £40
Do you think I that the rockers breaking would release the tension off the valves so when the piston hit the valves would not bend valves.
Fingers crossed for ya son.
Interesting thing with the N57 is that the inlet + exhaust valves are pretty much vertical with the piston in their alignment. Which suggests to me that they shouldn’t really bend much, but yes they smash the rocker arms to pieces
Bad luck on the timing chain.. but you’ve made the right decision to pass it on. I’m the same as you, if I have the equipment, I’d give it a go... but time is better spent in other areas!
Think of it as great content... it’s a shame... but I’m in for the full resolution 👍🙂
Its not bad luck. This happens to a lot of these engines. They are not built to last.
Sometimes those rockers are sacrificial so fingers crossed, agree re letting specialists do it, sometimes although you probably could eventually fix it and cobble it all back together, is it worth the hassle and cost of tools v paying someone who has the equipment time and knowledge to do it. From bitter experience and despite brief satisfaction of DIY I wish some jobs I’d left to the pros.
I know exactly what you mean 👍
I do hate passing on jobs sometimes though... 😬
Need a gallon of petrol to fix that ................. over roof and light it
A wise decision. Did a VW polo chain twice in two years. PITA job and that was done with the engine in place and only half the cylinders.
this Bmw series have this issue of chain broke,begin with a tic tic sound and after they crack
Tatăl Luptătorilor mine broke, no tictic sound.
good luck keep us posted
Fix it yourself surely it will be only 530d timing chain rebuild for the home mechanic? And very similar to n47 engine so info applies to them.
Used to work at German car specialist it’s a massive job
To be honest, I’m having that change of heart now... I’m already this far, so I’m working out how to do it myself on the driveway. First job is to get the head repaired, head gasket + bolts, timing chain kit... and how to physically do it from underneath by removing gearbox. That’s the way I think im going now anyway - forget what I said in the last video 👍😬
Nut Job That’s a £3k plus job at a recognised specialist? Second hand engine hoists are £300 on eBay just use and resell back on again.
Shame as you put so much effort in to car but right decision at this stage
Why bmw haven’t fitted updated tensioner kit as part of recall is beyond belief , not fair that these things are ticking time bombs
Amazing detail as I know its not easy keeping the camera running at the same time.
Bad news mate! Funny thing is I’ve just done the timing chain on a 53 plate 1.0 corsa and the rocker arms look identical!
Nutjob made this repair far more difficult than needed and the heath robinson ramps and gearbox removal method risked a severe crush injury. Once the broken timing chain had been found that could have been replaced from the top of the engine without needing to remove the transmission. Use the old broken chain to feed in a new one that is then riveted together. Some special tools needed or take the car to an indy. The timing chain is the weaker one of the two so likely to have broken, not the lower chain which is sized for driving the HP fuel pump and the camshafts.
OMG... just no 😩
At no point was a ‘crush injury’ a possibility. I fail to see a problem with ramps as cars have been worked on ramps since before you & I were born. At no point was I beneath the transmission during removal either - the only risk really was to my actual transmission if it were to become unbalanced perhaps & fall? Then that’s my problem really...
As for feeding a chain back around the HPFP sprocket from the top of the engine... 😂😂😂 I’m sorry but I just don’t think that’s remotely possible - especially after the chain has snapped & flung itself somewhere...
Mending an N57 timing chain is either an engine-out job, or a transmission-out job so that all 3 (probably stretched) chains can be renewed. By all means though, if I’m wrong I would definitely subscribe to someone who posts a timing chain repair video from the top as you describe 👍
@@Nut_Job. Yes, because the BMW TIS method for replacing the timing chain is from the top of the engine, not via the transmission. I noticed you had access to the TIS, I'm puzzled why you took the more difficult route?
@@Nut_Job. If the broken timing chain was not still in one piece then sure best to find all the pieces if possible. But hopefully any loose links would have dropped to the sump. On a high mileage car replacing all three chains is not a bad idea but that does mean removing the transmission - not sure I would have gone to that trouble. BTW on my 530d the HP fuel pump seals went leaking diesel into the sump which caused a high oil level warning. Had the £1000 pump replaced under warranty which I think is possible without removing the back cover off the engine to disconnect the drive sprocket.
Apologies, you are correct - there is a procedure for replacing just the top timing chain without engine or transmission removal on www.newtis.info.
This wouldn’t have worked in my situation unfortunately, as the chain had already failed & flung itself around 👍
The e39 would be a better shout. The m57 6 cylinder is bulletproof in the 530d
Ryan Davison even the e60 used the m57 to start with. I think they made them until about 2008ish. Yes m57 is a brilliant engine
Well, No. I like the E39 veeery much, but the 530d M57 is, when you buy /bought it, also worth to look at the high pressure pump, vacuum pump, renew complete vacuum system, check injectors, turbocharger, remove "drallklappen" from the intake manifold, clean the intake manifold, check agr valve, thermostat and then you have to deal with the typical rust problems of the E39, specially the tourings have a fatal rust problem at the trunk lid.
When it's a 30dA with the automatic tranny, then you will sooner or later repair that thing too. Timing chain can also be a problem.
I'd take a F10 rather than a E39 if you want a car that drives without worrying for a good while about repairs and rust. When you really want a E39, pick a good example, check for rust and any odd behaviour of the engine and any noise and buy it. But be prepared: Can be cost a lot of money, but you also might be lucky and the good ol E39 is only taking its regular oil changes and typical service parts...:D (Honestly I like my E39, cost me about 4-5k€ in repairs so far, parts and also some optical additions).
Cooper 2004 they made the m57 until the end of the e60 mate, then the f10 went over to the n57, that m57 was used for ages 😳
BexonBoy123 yeah ur right, I realised that after I said it. I was thinking of the e90 3 series that used both types in its lifetime 👍
Wort investing in a engine hoist mines served me well

It’s definitely on the list... it’s finding a place to store it though 🤨
Why do all N series engines seem to suffer with timing chains?
George Austers cheap materials
All N series use chain guides made in China, all of them, and they all disintegrate and fall off, then the chain breaks.
What's the mileage?
200.000-250.000 km
Good job
Thank you for your vídeos
I am wondering what those plastic parts inside the engine will look like after 20 years, seeing all heat cycles and chemicals. My car is 20 years old and many interior trim parts are brittle as hell. Planned obsolescence. By the way - what was the reason for the chain to snap?
I guess it failed due to the mileage?... it’s at about 164k miles I think, but I still think that’s a crap design imo.
I don’t have a major problem with the mixture of materials being used today; alloys, plastic/composites - even metal alloys fail due to stress fatigue over time. The problem is the difficulty accessing these parts to perform the service jobs - it’s just short-sighted engineering, basically saying “not our problem when it’s out of warranty” 🤨
@@Nut_Job. normally the chains would elongate due to wear, throwing a code for camshaft timing. Very unfortunate yours snapped. Good luck with the repair!
How many km’s does the car have? Its the first time i heard that the chain of the m57 could break! Had an e39 530dT with 650000km on, and yet going...
This is the N57 engine, so it’s not quite the same as the M57. It’s a 2012 F11 model with ~200k km on the clock.
No timing chain lasts forever though, so I’d be inclined to get yours checked at least if you’ve got 650k on the clock...
Nut Job i wash so shocked about iT that i saw the title for M57 Instead of N57... the N57 from 2008-2011/12 has this kind of issues ... the first line of M57 is so robust! The chains don’t fail hardly as often by the 2.0d diesels
to days diesel engines are less reliable. due by disign of the timming chain only being a single chain instead of being douplex .wether it is done on purpose i do not know? also i do not believe it is any advantage being at the back of the engine , it is just more expensive to repair . i believe there is a double chain mod available ?
I did have a quick look at duplex chain options. The bankroll is a bit low at this point though unfortunately ☹️
Which specialist did you take it to?
What did you do glue it back together
Don’t forget to let us know how much it cost and what was done.
Definitely 👍
Nut Job . My V8 X5 had the timing chain guides break and that cost £2200... That was without any head damage. Good luck.
This puts me off BMW. They really should have stepped in more on these chain issues
m47/m57 was miles better & easier to service
I think you’re right 👍
What is with BMW putting their timing chain on the back of the engine . It's such a pain doing it that way .
I know... 😫
Because its meant to be maintenance free for the cars lifetime however what they dont say is that they only consider the lifetime of the car to be 60-100k miles
Almost criminal IMO as any failure would result in three times the work / price (at least)
@@gegwen7440 that's the point all german cars are designed to maximise after market services from parts to mechanical issues that require specialist bmw technicians. That is how the german economy has thrive with a little Ingenuity in their marketing and a product every wants germany have become the powerhouse of the eu solely from their criminal exploitation of consumers.
How much Kilometers had your engine?
oil probably changed every 18,000 miles. And not every 6000 miles
Unlikely, as it’s an ex-police car. In for servicing every 4-6 weeks on average
Am I right in thinking that the rockers are designed to break to stop the valves bending ??
I don’t know for sure, but looking at the orientation & design I’d be inclined to agree it looks that way
*Orientation of the valve stems
I know the Mondeo 2016 model diesel has very similar rockers that are designed to snap that letting the valves bend look at Alan howlett he’s a utuber and recently had very similar problem on a mondeo
Alan howlatt
@@Nut_Job. I think it is to protect the piston and conrod. It seems very unlikely a valve would be usable after being hit with a piston.
Hi there, did you have classic symptoms before the chain snapped such as rattling etc. or did it just snap without warning? I have a well maintained N57 on 120k miles and I'm not sure if I should change mine just to be safe.
I don’t remember hearing anything particularly worrying before it snapped. Maybe there was a tiny sound I didn’t pick up on, but who knows? 🤷♂️
At 120k I wouldn’t be worried, but I would start planning for the top chain replacement at the very least. It’s not a massive job like mine was….
@@Nut_Job. thanks for replying, love all of your F11 videos by the way, really helping me out with my F10 preventative maintenance jobs. I won't do chain DIY but will aim to get it done definitely before 150k for some peace of mind.
Gotta love German engineering hey lets put timing chains at the back of the engine smh

I would love someone to explain to me the benefits of placing them on the back of the engine.
@@chrisj197438 only reason I can think of is more money for the dealerships in repairs.
Such a shame
Chris Atkinson
Well the whole point of a timing chain is that it shouldn’t really have to be replaced (provided the oil is kept changed and you don’t do half a million miles) so putting it at the back of the engine probably wasn’t seen as an issue.
The flaw was in the chains used I think!
@@owenb1t5014 the soft chain and srocket is a feature... it just dies not serve owners.
For the same cost you could have proper timing components to drive your money worth out of these money-pits
What year is the BMW Dean ?
Well done mate let's hope those rockers have sacrificed themselves for the good of the engine! Nutty place for a timing setup right at the back!
I know... 🤔
Its certainly something to bear in mind if buying almost any modern BMW in my opinion. The 2.0d N47 engines have a far worse reputation by all accounts... if I’d perhaps done my homework a bit better I could have done the timing chain immediately... hindsight is a great thing eh
Loads of timing chains are moving though. Mercedes new inline six has it at the rear. It is all to do with getting the engine low enough for pedestrian impact and less metal being higher in the engine bay

I changed my mind... 😁
What caused to happen this?You didn’t change the timing chain in time?After how many km it past from the change time?
BMW don’t tell you to change it.... it’s supposed to last the lifetime of the car (more like the lifetime of the warranty 🙄)
No they tell you Diesel engine needs to be change 120k (km) Gasoline engine 160(km).im asking that at how much Mileage this happened to you.I know a X6 that driven 210k(km) with first timing chain and it broke down.

Hi nut job 😄 Great effort but a sensible call 👍🏻
As this is a known fault can you get modified parts to stop this happening again or is it fit and forget and fingers crossed
The chains & guides are all apparently an ‘upgraded’ design - whatever that means? Who knows, but it should at least do another 100k, or I’ll be real mad 😡
It is more the guides that take the stress the chain tensioner changed.
BMW b series b47 and 57 share the exact same chain part number, oil sprayer etc. Only a few guides are different in design terms as the final n series engines following the timing chain issues

@@Nut_Job. laugh, just sold a 520d 2009 with 180k miles. Original chain from the dreaded "n47" engine. Proper maintenance and motorway miles 💪🏻
This was an ex-police traffic car. If you think poor maintenance is the issue then you need to look a little closer. You’ve actually been lucky, rather than the rule. Just look at the pathetic size of the top chain, plus the extremely awkward positioning at the back of the engine. Longevity has slipped down the priority list for BMW since previous generations of engines…. in the name of efficiency & emissions reduction. There’s always a trade off 🤷♂️

Is the N57 less reliable than the M57?

Those 2 white cords you have around your neck hanging in the engine are a recipe for disaster or even DEATH tuck them away man image getting them caught up with the engine running it would strangle you?
That’s a reasonable point 👍
However, in this video my engine has a broken timing chain so there’s very little (no) chance of anything turning in this engine right now.
I would certainly avoid wearing anything loose like that when inspecting a running engine though 👍
How do you get car into Neutral without starting engine??
If the car is working normally I think the gearbox should allow you to select Neutral (not 100% sure…)
However, if you need to ‘force’ the car into Neutral like I did then you can do that from underneath the vehicle. On the left-hand side of the gearbox you will see a vertically mounted bolt. Above the bolt is a small lever, so that as you tighten the bolt it will push the lever - this will force the gearbox into Neutral. When you tighten the bolt you will hear a ‘clunk’ noise & you should then be free to push the car around. Undo the bolt & the box will re-engage normal gearing 👍
@@Nut_Job. thank you brother ! I love the videos you made they give me hope overall. I just had my hpfp fail in my 2014 535d xdrive I will fix slowly but surely
Oh that’s a shame! Are you changing all the high pressure fuel rail parts? If I remember correctly, the concern with a HPFP failure is tiny metallic contamination of the fuel rail/system… even the fuel tank (because of fuel return line?) needs checking/clearing doesn’t it?
At least it’ll need new timing chain etc. so you can give it some extra years. I would also advise replacing the oil pump too 👍
